In-N-Out Secret Menu Hacks

What is on the In-N-Out Secret Menu?

This is the most complete and accurate list of In-N-Out Burger secret menu items. Some might argue that In-N-Out's Off-Menu Hacks are even more popular than regular In-N-Out items - and we agree that they would have a pretty strong argument. But why are the secret menu customizations so popular ? We don't know for sure, but we bet all the other fast food chains wish they knew the answer.

What's on the In-N-Out secret menu?

There are tons of secret menu items at In-N-Out, but we will start with the secret menu burgers! You can order a 3x3 (three by three), 4x4 (four by four), or anything inbetween a hamburger and a 4x4. The first number signifies how many burger patties you want, while the second number lets them know how many slices of melty American cheese you want on your burger.

Besides switching up the amount of meat and cheese, you can add some flavor by getting the oh-so-popular Animal Style Burger. You can get your burgers cooked medium-rare, well done or even mustard grilled. And if you don't like meat, you can always get the vegetarian-friendly Grilled Cheese Sandwich. Secret toppings for your burgers include grilled onions, pickles, yellow sport chili peppers, extra tomatoes, extra lettuce, and extra spread.

What about the fries at In-N-Out, any secrets there? You better believe it. You can get Animal Style Fries or upgrade to the Ultimate Animal Style Fries if you are feeling extra hungry. They also sell cheese fries if you feel like you want something inferior to the Animal Style Fries, just sayin'. Besides that, you can get your fries cooked to many different levels of "done-ness". From light fries to extra well done, you can get your fries just how you like them and made to order.

The secret In-N-Out Burger drinks and shakes are guaranteed to put a smile on your face. They will make root beer floats, neapolitan milkshakes, and any other combination that you can think of! If you can't find something you like, you are just way too picky, because everyone knows that In-N-Out is amazing!

What makes the Flying Dutchman unique is its simplicity. It’s the bare essence of a burger, just two slices of American cheese melted between two beef patties. That’s it! No bun, no lettuce, no tomato, no onions, no spread.

There’s something liberating about the idea of stripping down a burger to its most basic elements. It’s a reminder that sometimes, less really is more. The Flying Dutchman isn’t trying to be fancy or elaborate; it’s just delivering pure beefy, cheesy goodness.

Of course you can add on as many fixings as you want to customize it even further, but this is the OG flying dutchman secret recipe.
