The In-N-Out Secret Menu Items You Never Knew Existed

Nothing makes a fast-food experience more fun than taking things off the menu. It’s like a secret shared language between you and the cashier. Well, believe it or not, at In-N-Out, there are more "secret menu" options than there are regular menu items. 

The beloved West Coast burger joint is known for its classic, limited menu of burgers, fries, and shakes. But, over the years, the most loyal patrons have gotten creative with their orders, coming up with every possible way to repurpose the simple ingredients in the In-N-Out kitchen and produce new fan-favorites. 

From Neapolitan shakes to towering four-story burgers, there are now dozens of menu twists only the real In-N-Out enthusiasts know about, so we’ve scoured the internet to collect them all. If you don’t see it on this list, it probably won’t pass at the counter either (sorry to your 16x16 burger).

So, if you’re rolling up to In-N-Out for the first time, forget the drive-thru board—here’s the real menu to order from. And whatever you do, don’t leave without your free merch—AKA a hat and stickers!

In-N-Out Secret Menu Burgers

Animal Style: This burger has the works: fried mustard (an In-N-Out specialty), grilled onions, pickles, and extra Thousand Island spread will top your regular burger patty. 

3x3: Just like the Double-Double will give you two beef patties and two slices of cheese, the 3x3 will up each of those offerings by one. You‘ll get three beef chuck patties and three slices of American cheese.

4x4: You guessed it, a whopping four patties and four cheese slices will be sandwiched between your burger bun. 

Flying Dutchman: This bun-less burger will be a stack of two burger patties and two cheese slices.

Protein Style: This burger is wrapped in a lettuce bun for low-carb eaters. 

Onion Bun: Onion lovers, you can skip the bun and get whole grilled onions on either side of your burger instead. It offers a seriously savory flavor, but, we're warning you—it's also seriously messy.

Tomato Bun: Tomato slices replace the bun on this burger.

Grilled Cheese: No burger here, but a great option for kids or meat-free eaters. The grilled cheese consists of two slices of melted American cheese sandwiched between toasted burger buns. It doesn't include any toppings, so be sure to order any that you’d like. 

Pup Patty: This one’s for your furry friend! Sometimes referred to as the Scooby Snack, this plain beef patty has no bun or condiments, making it the perfect treat for your canine companion. 

Monkey Style: Sorry, but this order doesn’t exist. It was once rumored you could get an animal-style cheese fry on top of your burger, but the restaurant confirmed the story as false. Don’t order it at the counter, but there’s nothing stopping you from recreating the mythical menu item yourself!

In-N-Out Secret Menu Fries

Animal Style: Just like the burger order, this basket of fries will come topped with fried mustard, grilled onions, extra spread, and melted cheese. It’s arguably the most famous offering on the menu!

Cheese Fries: Don’t feel like going full-animal? Hold the sauce and condiments—these fries will just be covered in melty American cheese.

Roadkill Fries: When you can’t choose between fries or a burger, get both. This combo will give you a basket of animal fries topped with a flying Dutchman (two burger patties and two cheese slices). This order might be too impromptu for some locations, so if they can’t complete the request, just ask for an animal fry and flying Dutchman separately. 

Well-Done: If you like your fries extra crispy, this is the way to order them. These fries come out golden brown and so crispy, they’re almost crunchy. If you like a really fried fry you can even ask for extra well-done, but those will come out nearly burnt.

Light: We can’t say we’d recommend this version, but you can get your fries cooked light or light-well for a softer texture. 

Lemon Pepper Fries: This is more of a DIY fry job, but it’s a great way to add flavor to the regular fries. Ask for salt, pepper, and lemon wedges with your fry order. Dump your fries into an empty In-N-Out bag, sprinkle on salt and pepper, and add a squeeze of lemon juice, then shake until fully coated. 

In-N-Out Secret Menu Drinks

Neapolitan Shake: This is the complete trio of all three shake flavors—chocolate, vanilla, and strawberry—in one.

Black and White Shake: Chocolate and vanilla shakes are swirled together. 

Root Beer Float: This treat is made up of half root beer soda and half vanilla shake. 

Arnold Palmer: Sweet tea and lemonade—a summertime favorite!

Lemon-Up: This drink order will combine the restaurant’s signature pink lemonade with 7Up soda for a fun, fizzy treat.

In-N-Out Secret Menu Extras

Bun: Just like the fries, your bun can be cooked to your extra liking by requesting 'light toast', 'extra toast', or 'no toast'.

Onions: You can get your onions prepared in almost any fashion imaginable. Raw chopped, grilled, whole raw, and whole grilled are all options for your burger topping.

Chopped Chilis: Need a little heat? You can add sliced banana peppers to any burger free of charge or to fries for a small fee. We’d recommend adding these spicy peppers onto anything animal-style. 

Pickles: Another tasty topping option for your burger or fries.

Cold cheese: If you don't dig melted cheese, you can add a slice of American cheese to your burger without it being heated on the grill.

Cut-in-Half: It may seem silly, but it's the easiest way to split a burger among the kids.
