In-N-Out Burger is perhaps one of the best known fast food joints in the American Southwest. Their menu consists of the usual cheeseburger, regular hamburger, and the Double-Double, which has two slices of cheese and two burger patties. They come with onions, spread, lettuce, or tomato, and customers are asked to specify if they want the ingredients fresh or grilled. But what a lot of people don’t know about is the In-N-Out secret menu.
Although they are not advertised, these menu items are available in most locations. They have ingredients that can be mixed and matched to come up with an original recipe. You can’t go wrong on this secret menu, but before you can enjoy it, you need to know what’s on it.
Flying Dutchman
The Flying Dutchman is a bizarre-looking concoction, sort of reminiscent of the KFC Double Down but with beef patties instead of fried chicken. It’s a burger with no buns, no onions, and no lettuce—only two slices of melted cheese, sandwiched by two beef patties. If that sounds too plain for you, you can always add grilled onion or ask for the burger “Animal Style.” Speaking of that…
Animal Style

Animal Style is arguably the most well-known “secret” on the secret menu. It’s the social media phenomenon that you’ve seen circulate on Instagram – the In-N-Out burger and/or fries with loads of cheesy, beefy goodness on top. An Animal Style Burger is a beef patty made with mustard and loaded with extra spread (thousand island sauce), pickles, and caramelized onions. You can also get Animal Style Fries, which comes the same ingredients in the burger but layered on top of the fries.
Veggie Burger
In-N-Out is known for its beef burgers, but that doesn’t mean vegetarians can’t still enjoy the fast food chain. The secret menu houses a makeshift Veggie Burger that is essentially the same thing as the Grilled Cheese, without the cheese. Toppings include onion, pickle, lettuce, and tomato, and well as mustard and ketchup and In-N-Out’s signature spread.
Double Meat
Not all secret menu items have to be out there. This one is a classic burger with basic toppings, but it’s a no-fail option if you’re craving a hearty meal. The Double Meat burger comes with two beef patties, sliced tomato, spread, hand-leafed lettuce, and onions (optional) on a bun.
Grilled Cheese

In-N-Out’ Grilled Cheese is far from two slices of bread and melted cheddar. It’s a “loaded” sandwich with all the fixings, and it’s an excellent option if you’re a vegetarian or want something other than a meaty burger. The Grilled Cheese includes American Cheese, sliced tomato, lettuce, and spread on two pieces of toasty warm bread.
Animal-Style Flying Dutchman
Still no bun, of course, but with your Flying Dutchman, you can add spread (a variety of Thousand Island dressing), grilled onions, and fried mustard. Speaking of onions, you get the grilled and chopped ones if the ingredients are hot, like those with melted cheese. On the other hand, fresh onions are added to ingredients that are cold—those with fresh lettuce and tomatoes, for example.
Monkey Style
Would you like fries with your burger? Yes? Then stuff your animal style fries inside a Double-Double. This menu isn’t a big secret since a Twitter rumor started this a few years ago. Try to request for this from In-N-Out and see if they will make it for you; if not, you can always do it yourself. It tastes absolutely wonderful. Try it!
Protein Style

If you’re on a keto diet or simply want to cut back on calories and carbs, you can opt for ordering your burger “protein style.” All that means is that you get your sandwich wrapped in lettuce instead of a bun. It’s just as delicious and is the perfect excuse to add extra toppings or make it Animal Style.
Veggie Sandwich
As stated above, this creation is really for those who don’t want animal products in their food. What you’ll have is a combination of a freshly baked bun, tomatoes, onions, and lettuce, which will be appreciated by vegans. If you’re vegetarian, you can add the spread, if you want. And to make things a little bit exciting, since the patties and cheese were already removed, add fries inside the sandwich. They are fried using “100% pure, cholesterol-free vegetable oil,” so you should have no worries about how it was done. Get the extra-well ones to add crisp in every bite.
3 x 3

You may recognize the 3 x 3 from other secret menus. You can technically order it anywhere that serves burgers, but it’s especially delicious at In-N-Out. Ask for it by name or explain the order to the worker – either way, you’ll get a burger with three patties, tomato, spread, lettuce, three slices of American cheese, and onions on a bun.
4 x 4
The 4 x 4 is exactly the same thing as a 3 x 3, except with four beef patties and four slices of cheese, as well as tomato, spread, hand-leafed lettuce, onions, and a bun. Good luck eating this sucker – it’s as massive (and full of calories) as it sounds.
Other In-N-Out Menu Hacks
Let’s be honest, most people know about the In-N-Out secret menu, but a lot of fans don’t know about the options when it comes to condiments, onion styles, fries, and drinks. Yes, there’s the basics on the regular menu, but did you know you can order any of these options with your meal?
- Condiments – Spread, hot yellow chili peppers, cold cheese
- Onion styles – Raw sliced/standard, chopped; fresh or grilled
- Fries ($1.60) – Light, light well, well, extra-well, animal style
- Drinks – Root beer floats, Lemon-Up, lemonade and tea mix, choco-vanilla swirl shake, Neapolitan shake, large and extra large shake
An extra patty will cost $0.75, while an extra cheese will cost $0.30. If you’re going to get a meal, the cost would be from $5.25 to $8, depending on the kind of sandwich you’re having or the add-ons you want to include. Enjoy mealtime with your friends so you can compare notes about who made the best combinations.
Food is best enjoyed with friends and loved ones. Go get the different combinations so you will have an idea what to order in your next visit. And don’t forget to order the other items from their secret menu, like the floats and the milkshakes.
