In-N-Out Secret Menu: Items, Codes, and How to Order

Updated August 2026

In-N-Out's famous secret menu includes customer-created and company-recognized ways to customize its simple burger menu, including Animal Style, Protein Style, Double-Meat, the 3x3, the 4x4, and Grilled Cheese. In-N-Out officially calls it the "Not So Secret Menu" because the company says these items are simply popular ways customers have asked to have their burgers prepared over the years.

There are also other well-known In-N-Out orders, such as the Flying Dutchman, Animal Style fries, extra-toasted buns, chopped chilies, different onion preparations, and customized shakes.

However, there is an important difference between an actual In-N-Out customization and something invented by social media.

The internet is filled with enormous lists claiming to reveal dozens of "secret" In-N-Out foods. Not every viral name is an official In-N-Out menu item.

The real story is more interesting.

In-N-Out keeps its regular menu extremely small, but employees can use the same ingredients in different combinations. Over decades, customers developed favorite ways of ordering those ingredients. Some became so popular that In-N-Out eventually started recognizing the names itself.

This guide explains the real In-N-Out secret menu, what each item contains, how Animal Style started, what the Flying Dutchman actually is, which internet orders should be treated cautiously, and why having a secret menu has become such an important part of the In-N-Out brand.

What Is the In-N-Out Secret Menu?

The In-N-Out secret menu is a collection of popular customizations that are not all displayed prominently on the standard restaurant menu board.

In-N-Out officially refers to this as its Not So Secret Menu.

The company explains that it does not really have secrets. These are simply different ways customers like their burgers prepared.

The regular menu remains remarkably simple:

• Double-Double
• Cheeseburger
• Hamburger
• French fries
• Shakes
• Beverages

Instead of adding dozens of completely different burgers, In-N-Out lets customers modify those core products.

Official In-N-Out Not So Secret Menu at a Glance

In-N-Out's current Not So Secret Menu page highlights popular customizations rather than claiming that these are the only possible ways to order.

1. Animal Style

Animal Style is the most famous item on the In-N-Out secret menu.

Customers can order their burger Animal Style.

An Animal Style burger includes:

• A beef patty cooked with mustard
• Pickles
• Extra In-N-Out spread
• Grilled onions
• Hand-leafed lettuce
• Tomato

The mustard-cooked patty is particularly important.

Rather than simply putting mustard on the finished burger, mustard is applied as part of the cooking process.

Combined with grilled onions, pickles, and extra spread, the result is tangier, richer, and more heavily seasoned than a standard burger.

Where Did Animal Style Come From?

Animal Style has been around much longer than social media.

In-N-Out's official history traces Animal Style back to 1961.

The company says the preparation developed in response to customer requests.

That is important because it explains how the entire secret-menu culture developed.

In-N-Out did not necessarily sit down and create a large hidden menu as a marketing campaign.

Customers asked for different preparations.

Employees made them.

Certain combinations became popular.

Customers gave those combinations recognizable names.

Eventually, some became part of In-N-Out culture.

Can You Order a Double-Double Animal Style?

Yes.

Animal Style is a preparation rather than one specific burger size.

A customer can order:

• Hamburger Animal Style
• Cheeseburger Animal Style
• Double-Double Animal Style

You can also combine Animal Style with other permitted customizations.

That flexibility is one reason the secret menu feels much larger than it really is.

2. Animal Style Fries

Animal Style fries are among the most famous In-N-Out orders, even though the company's online Not So Secret Menu focuses primarily on burger preparations.

The popular fry customization combines In-N-Out's freshly cut fries with:

• Melted American cheese
• Grilled onions
• In-N-Out spread

The result is considerably richer than an ordinary order of fries.

For many first-time visitors, a Double-Double Animal Style with Animal Style fries has become one of the classic ways to experience In-N-Out.

What Is In-N-Out Spread?

Spread is In-N-Out's signature burger sauce.

It is a creamy and tangy sauce containing ingredients including:

• Oil
• Cucumbers
• Tomatoes
• Vinegar
• Egg
• Sugar
• Mustard seed
• Spices

Customers can also request packets of spread.

Extra spread is one of the defining components of an Animal Style burger.

3. Protein Style

Protein Style replaces the hamburger bun with lettuce.

Instead of placing the burger between two toasted buns, In-N-Out wraps it in hand-leafed lettuce.

You can order several burgers Protein Style, including:

• Hamburger Protein Style
• Cheeseburger Protein Style
• Double-Double Protein Style

The meat, cheese, tomato, spread, and other selected toppings remain inside the lettuce wrap.

Is Protein Style the Same as No Bun?

Not exactly.

Ordering a burger without a bun simply removes the bread.

Protein Style specifically replaces the bun with lettuce, creating a wrap around the burger and toppings.

That makes the burger easier to hold and eat.

Can You Order Protein Style Animal Style?

Yes.

This is a perfect example of how In-N-Out's menu system creates so many combinations.

You can ask for a burger:

Protein Style and Animal Style.

You then receive the Animal Style preparation while the traditional bun is replaced with lettuce.

4. Double-Meat

Double-Meat is for customers who want more beef without automatically adding cheese.

It contains:

• Two 100% American beef patties
• Lettuce
• Tomato
• Spread
• Onions if requested
• Toasted bun

The important difference is that it does not include the two slices of cheese found on a Double-Double.

Double-Meat vs. Double-Double

The Double-Meat demonstrates how In-N-Out can create another recognizable menu item without introducing any new ingredients.

5. The 3x3

The 3x3 is also known as the Triple Triple.

It contains:

• Three beef patties
• Three slices of American cheese
• Lettuce
• Tomato
• Spread
• Onions if requested
• Toasted bun

The name is extremely easy to understand.

The first number represents the patties.

The second represents the slices of cheese.

Therefore:

3x3 = three patties and three slices of cheese.

Can You Make a 3x3 Animal Style?

Yes.

A customer can combine the larger burger with Animal Style preparation.

That creates a much heavier burger with mustard-cooked beef, grilled onions, pickles, and extra spread.

6. The 4x4

The 4x4 is the next step above the 3x3.

It is also referred to as the:

• Four by Four
• Quad Quad

The burger contains:

• Four beef patties
• Four slices of cheese
• Lettuce
• Tomato
• Spread
• Optional onions
• Toasted bun

Like the 3x3, it is made from ingredients already used elsewhere in the restaurant.

Can You Order a 5x5, 10x10, or Even Bigger Burger?

This is where internet secret-menu lists can become confusing.

In-N-Out has historically been associated with customers trying to order enormous numbers of patties and cheese slices.

The company's current public Not So Secret Menu specifically promotes the 3x3 and 4x4 as its larger burger options.

If you see an internet article claiming that any enormous number automatically represents an official In-N-Out secret menu item, do not assume that is current policy.

Restaurant policies and available customizations can change.

The safest approach is to order one of the combinations the company currently recognizes or ask the restaurant what it can prepare.

7. Grilled Cheese

In-N-Out's Grilled Cheese uses the burger ingredients without the beef.

It includes:

• Two slices of melted American cheese
• Hand-leafed lettuce
• Tomato
• Spread
• Onions if requested
• Toasted bun

This is one of the official items included on In-N-Out's Not So Secret Menu.

Is In-N-Out Grilled Cheese Vegetarian?

The Grilled Cheese does not contain a beef patty and is commonly ordered as the chain's vegetarian sandwich option.

However, customers following strict vegetarian diets or concerned about cross-contact should ask the restaurant directly about current preparation procedures.

Can You Order Grilled Cheese Animal Style?

Customers can request many of the same available toppings and modifications on the Grilled Cheese.

Because there is no beef patty, however, the mustard-cooked-patty component of a traditional Animal Style burger does not apply in the same way.

It is often clearer to simply ask for the toppings you want, such as:

• Grilled onions
• Pickles
• Extra spread

8. The Flying Dutchman

The Flying Dutchman is one of In-N-Out's most famous minimalist orders.

It consists of:

• Two beef patties
• Two slices of cheese

There is traditionally no bun and no standard lettuce, tomato, or spread.

In-N-Out's own company history officially identifies the Flying Dutchman as a Not So Secret Menu item.

Who Created the Flying Dutchman?

According to In-N-Out's official history, the Flying Dutchman was created by Guy Snyder, the son of founders Harry and Esther Snyder.

Guy Snyder later served as the company's chief executive.

The fact that the Flying Dutchman has a connection to the Snyder family makes it particularly interesting compared with internet-created secret-menu names.

Flying Dutchman vs. Protein Style

The two are not the same.

Protein Style is essentially a burger with lettuce replacing the bun.

The Flying Dutchman strips the concept down to meat and cheese.

Can You Add Onions to a Flying Dutchman?

In-N-Out already offers onions and grilled onions as burger ingredients, and customers frequently customize their orders further.

If you want onions or another available topping with a Flying Dutchman, the simplest approach is to describe exactly what you want when ordering rather than relying on an internet nickname.

What Other Customizations Can You Ask for?

The secret menu becomes much larger when you stop thinking in terms of named items and start thinking in terms of ingredients.

In-N-Out's current ingredient information identifies add-ons including:

• Pickles
• Chopped chilies
• Grilled onions

Customers can also request changes involving the bun, onions, spread, mustard, cheese, and other standard burger ingredients.

Chopped Chilies

Customers looking for more acidity and heat can ask for chopped chilies.

These peppers can be added to a burger or eaten alongside the meal.

Because the restaurant already stocks them as an add-on, this is a relatively simple way to change the flavor of a standard burger.

Grilled Onions

Grilled onions are one of the defining ingredients in Animal Style, but customers do not need to order an entire burger Animal Style to get them.

You can simply request grilled onions.

This is another example of how ingredient-level customization works at In-N-Out.

Raw Onion vs. Grilled Onion

The type of onion can noticeably change a burger.

Raw onion provides:

• Crunch
• Sharpness
• Fresh onion flavor

Grilled onion provides:

• Softer texture
• Sweeter flavor
• More cooked and caramelized notes

This is a relatively small kitchen modification that creates a noticeably different burger.

Can You Ask for Extra Toast on the Bun?

In-N-Out's buns are toasted as part of the normal preparation.

Customers commonly request different levels of toasting when the restaurant can accommodate them.

If you want a particularly crisp bun, it is better to explain that preference when ordering rather than rely on a complicated secret-menu nickname.

Can You Order Fries Well Done?

In-N-Out fries are made from whole potatoes cut inside the restaurant and cooked in sunflower oil.

Customers sometimes request different levels of fry cooking, including a crispier preparation.

These requests are better viewed as customizations rather than major official secret-menu items.

Availability can depend on current restaurant procedures and how busy the kitchen is.

What Is a Neapolitan Shake?

One of the best-known unofficial In-N-Out drink customizations is commonly called a Neapolitan shake.

It combines the chain's three traditional shake flavors:

• Chocolate
• Vanilla
• Strawberry

Because In-N-Out already makes all three flavors from real ice cream, combining flavors is a natural extension of the existing shake menu.

However, it is better to think of mixed shake flavors as a customization rather than assume every nickname found online is part of the company's official Not So Secret Menu.

Is There Really a Root Beer Float?

In-N-Out sells both soft drinks and real ice cream shakes, which has led customers to develop various beverage combinations over the years.

Again, this demonstrates the central idea behind the secret menu.

Customers experiment with ingredients already available in the restaurant.

Some combinations become widely known even though they may never appear on the main menu board.

What In-N-Out Secret Menu Items Are Fake?

This is an increasingly important question because social media and food blogs constantly create new names.

You may encounter online lists mentioning names that In-N-Out itself does not use.

A viral nickname does not automatically mean employees are trained to recognize it.

If an online item involves normal In-N-Out ingredients, the restaurant may still be able to make a similar combination.

But instead of saying an obscure name, describe the ingredients.

For example, saying:

"Can I get grilled onions and chopped chilies on my Double-Double?"

is clearer than assuming an employee will recognize a name created by a TikTok account.

Why Does In-N-Out Have a Secret Menu?

The most important answer is that In-N-Out's menu has always been highly customizable.

The company itself says its Not So Secret Menu represents ways customers like their burgers prepared.

Over time, several operational and marketing advantages developed from that system.

1. Customers Created Many of the Ideas

Animal Style is the clearest historical example.

In-N-Out says it began preparing Animal Style burgers in 1961 in response to customer requests.

Instead of telling customers they could only order exactly what was printed on the menu board, the company developed a culture of customization.

2. In-N-Out Can Keep Its Main Menu Small

This is one of the smartest aspects of the system.

Imagine two restaurant strategies.

Strategy A

Put all of these on the menu:

• Hamburger
• Cheeseburger
• Double burger
• Triple burger
• Quadruple burger
• Lettuce-wrap burger
• Mustard-grilled burger
• Grilled-onion burger
• Vegetarian cheese sandwich
• Meat-and-cheese burger without bread

Strategy B

Put only a few core burgers on the main menu and teach employees how to customize them.

In-N-Out essentially chose Strategy B.

The menu board stays simple while experienced customers still have many choices.

3. Most Secret Items Use the Same Ingredients

This is extremely important from a restaurant operations perspective.

In-N-Out does not need to stock a completely separate pantry for the secret menu.

The same major ingredients can be recombined:

• Beef patties
• American cheese
• Buns
• Lettuce
• Tomatoes
• Onions
• Pickles
• Spread
• Mustard
• Chilies

A 3x3 does not require a new protein.

Protein Style does not require a specialty bread.

Animal Style does not require a completely separate sauce.

The restaurant gets variety without the inventory complexity that normally comes with a huge menu.

4. The Secret Menu Creates Insider Knowledge

Knowing how to order at In-N-Out became part of the experience.

A first-time customer might order:

"A Double-Double."

A longtime fan might say:

"Double-Double Animal Style, Protein Style, add chopped chilies."

The second customer feels like they know something about the restaurant that casual visitors do not.

That feeling creates loyalty.

5. Customers Tell Other Customers About It

The secret menu generated word of mouth long before TikTok, Instagram, or YouTube existed.

Someone might tell a friend:

• "Next time, order Animal Style."
• "Try a 3x3."
• "You can get it wrapped in lettuce."
• "Ask for grilled onions."

Every conversation becomes free advertising for In-N-Out.

6. The Menu Gives Fans Something to Debate

People love discussing their perfect In-N-Out order.

One customer prefers:

• Double-Double Animal Style
• Animal Style fries

Another prefers:

• Protein Style
• No tomato
• Chopped chilies
• Grilled onions

Another may prefer a plain cheeseburger.

This creates endless social-media posts and conversations without In-N-Out needing to release a new burger every month.

7. It Makes a Simple Menu Feel Much Bigger

In-N-Out appears to have one of the smallest menus in fast food.

In reality, customization creates dozens of possible combinations.

A customer can change:

• Number of patties
• Amount of cheese
• Bun or lettuce
• Onion preparation
• Pickles
• Spread
• Mustard preparation
• Chilies

A limited ingredient list therefore produces a surprisingly large number of possible meals.

Why Doesn't In-N-Out Just Put Everything on the Menu Board?

A giant menu board would work against one of In-N-Out's biggest strengths: simplicity.

A new customer can walk into the restaurant and immediately understand the main choices.

They do not need to read several digital screens filled with:

• Limited-time sandwiches
• Breakfast
• Chicken
• Salads
• Wraps
• Seasonal burgers
• Dozens of side dishes

The secret-menu system lets the company serve both groups.

New customers get simplicity.

Regular customers get customization.

Is the In-N-Out Secret Menu Actually Secret?

No.

That is why In-N-Out calls it the Not So Secret Menu.

The company publishes several of these preparations on its own website.

Employees are familiar with the major company-recognized items.

The "secret" part mostly comes from the fact that not every option is printed on the main menu board hanging above the counter.

Why Is Animal Style Not on the Regular Menu?

Animal Style is one of the most famous In-N-Out orders, but keeping it as part of the customization culture helps preserve the company's simple menu format.

It also reinforces the idea that In-N-Out fans can personalize their burgers rather than choosing between dozens of preset sandwiches.

What Is the Best In-N-Out Secret Menu Item for a First Visit?

For someone who has never tried In-N-Out, a Double-Double Animal Style is probably the most recognizable secret-menu experience.

It includes:

• Two beef patties
• Two slices of cheese
• Mustard-cooked beef
• Grilled onions
• Pickles
• Extra spread
• Lettuce
• Tomato
• Toasted bun

Customers who want the standard In-N-Out experience first may prefer trying a regular Double-Double before comparing it with Animal Style.

Best Secret Menu Order for More Meat

Consider:

• Double-Meat if you want two patties without extra cheese
• 3x3 if you want three patties and three cheese slices
• 4x4 if you want four patties and four cheese slices

Best Secret Menu Order Without the Regular Bun

Protein Style replaces the bun with lettuce.

For an even simpler combination, the Flying Dutchman consists primarily of beef patties and cheese.

Best Secret Menu Order Without Beef

The Grilled Cheese removes the beef patty while retaining cheese and standard burger-style toppings.

Best Secret Menu Order for More Flavor

Animal Style is the obvious starting point.

Customers can also experiment with:

• Chopped chilies
• Grilled onions
• Pickles
• Extra spread

How to Order From the In-N-Out Secret Menu

Ordering is usually straightforward.

For widely recognized options, simply say the name.

Examples:

• "Double-Double Animal Style."
• "Cheeseburger Protein Style."
• "I'll have a 3x3."
• "I'll have a 4x4."
• "Grilled Cheese."
• "Double-Meat."

For less common modifications, describe exactly what you want.

For example:

"Double-Double with grilled onions and chopped chilies."

This reduces confusion.

What Not to Do When Ordering a Secret Menu Item

Do not assume every strange name from social media is something employees are required to recognize.

If you saw an order online and are unsure whether the nickname is real, describe the ingredients instead.

This is easier for:

• The customer
• The cashier
• The kitchen

Why the Secret Menu Is Brilliant Restaurant Marketing

From a business perspective, In-N-Out's secret menu is one of the most successful examples of customer-driven menu marketing.

It Creates Curiosity

The phrase "secret menu" immediately makes people want to know what they are missing.

It Creates Free Content

Customers constantly produce:

• TikTok videos
• YouTube videos
• Instagram posts
• Reddit discussions
• Food articles

explaining how to order.

It Rewards Repeat Visits

A customer may try a regular Double-Double on the first visit.

Then:

• Animal Style
• Protein Style
• A 3x3
• Chopped chilies
• A different onion preparation

on later visits.

The restaurant has not changed its core menu, but the customer still has something new to try.

It Strengthens Brand Culture

Knowing the menu language makes customers feel like members of an In-N-Out community.

That is difficult for competitors to recreate simply by adding more burgers.

What Other Restaurants Can Learn From In-N-Out

The biggest lesson is not necessarily that every restaurant should create a fake secret menu.

The smarter lesson is that menu variety does not always require additional inventory.

A restaurant can ask:

• Can existing ingredients create additional combinations?
• Are customers already requesting the same modification?
• Can a popular customization receive a memorable name?
• Can customers personalize dishes without slowing down the kitchen?

When done properly, customization can increase customer choice while keeping the kitchen relatively simple.

Is there a Neapolitan shake?

Mixing chocolate, vanilla, and strawberry has long been a popular In-N-Out customization, but mixed shake combinations should be distinguished from the core items the company currently displays on its official Not So Secret Menu.

Can I customize my fries?

Customers commonly request different fry preparations and toppings. The restaurant's ability to accommodate a particular request can depend on current policies and operations.

Final Thoughts

In-N-Out's secret menu is famous because it turns one of the smallest menus in fast food into one of the most customizable.

The company officially calls it the Not So Secret Menu because there is not really a hidden kitchen full of ingredients customers are not supposed to know about.

Instead, most of the famous orders rearrange ingredients In-N-Out already uses every day.

Animal Style adds mustard-cooked beef, pickles, grilled onions, and extra spread.

Protein Style replaces the bun with lettuce.

Double-Meat increases the beef without automatically adding cheese.

The 3x3 uses three patties and three cheese slices.

The 4x4 uses four of each.

Grilled Cheese removes the beef while keeping cheese and familiar burger toppings.

The Flying Dutchman reduces the burger to two patties and two cheese slices.

Customers can then go even further with available ingredients such as grilled onions, chopped chilies, pickles, and spread.

The system is particularly clever because In-N-Out gets menu variety without maintaining the massive inventory required by many competing fast-food chains.

It also gives customers something equally valuable: a feeling that they know how to order like an In-N-Out regular.

That insider culture has generated decades of word of mouth.

People tell their friends to try Animal Style.

Tourists search for the secret menu before visiting California.

TikTok creators film unusual combinations.

Food websites debate the best order.

All of that keeps people talking about a restaurant whose main menu remains centered on essentially the same burgers, fries, shakes, and drinks.

Perhaps the most impressive part is that this did not begin with TikTok or an internet marketing campaign.

In-N-Out traces Animal Style to 1961, when the company began preparing burgers that way in response to customer requests.

The secret menu therefore reflects something that has been central to In-N-Out for decades: keeping the restaurant simple while still trying to give customers the burger they want.
