These copycat In-N-Out cheeseburgers are simply amazing! We don't eat fast food much at all but if we do In-N-Out is our go-to place. Let's not forget about that sweet and tangy sauce, each bite sends your taste buds into overdrive. No need for ketchup for the fries when you have this amazing sauce to dunk them in. If you prefer a grilled burger try my Pepper Jack Burger.

Why this recipe works

I'm not sure why such a simple burger can taste so amazing, and this secret sauce is spot on. These are so close to the real thing you have to give it a try. The burgers are extremely simple to make like my Skillet Burger and easy Smash Burgers. Just some salt and pepper and a spread of mustard then cooked on a hot skillet to form an amazing crust.

Recipe faq's

What is In n Out?

If you haven't heard in-n-out restaurant is a delicious fast-food chain primarily on the west coast. They use fresh simple ingredients prepped daily, and make each burger one at a time.

What is animal style burger?

It's one of the options on their secret menu, like double double animal style. Onions are cooked down in a skillet and then caramelized onions are added to a burger to make it animal-style.

Can you make these ahead of time?

This in-n-out cheeseburger is best made fresh but I will prep the beef patties and place them on parchment paper in an airtight container and make the rest the next day. The in-n-out sauce can be made ahead and stored in a container in the refrigerator.

Can you taste the mustard?

Adding the mustard on one side is an In-n- out trick to get that unique crust. Don't worry the mustard cooks and you don't taste it.

  • 1 pound ground beef 80/20
  • 1 teaspoon kosher salt
  • 1/2 teaspoon fresh ground black pepper
  • 4 tablespoons mustard
  • 8 slices American cheese
  • 1 large beefsteak tomato
  • Iceberg lettuce leaves
  • 1 large onion cut into slices
  • 8 hamburger buns

For the special sauce

  • 1/4 cup mayonnaise
  • 2 tablespoons ketchup
  • 1 tablespoon sweet pickle relish


  • Form meat into eight patties on a piece of parchment paper then cut a square around each patty, this helps place the patty into the hot skillet. You want the patties thin and slightly larger than the size of your bun. Sprinkle with salt and pepper. Let come to room temperature for about 15 minutes.

  • Meanwhile mix the mayonnaise, ketchup, and relish in a small bowl

  • Preheat a cast-iron skillet on medium-high heat add 1/2 teaspoon oil and place your buns split side down in the heated pan, cook until toasted about 1 minute. Set aside and cover to keep warm.

  • Pick up a patty and place the salt and pepper side down into the hot skillet, then pull off the parchment paper. Cook without moving until well browned and crusty on the first side, about 2½ minutes. While they are cooking, spread 2 teaspoons of mustard on the raw side. Then flip and top each side with 2 slices of cheese continue cooking for 1 more minute.

  • Spread sauce on the bottom toasted bun, place tomato, onion, and lettuce then patty with melted cheese add the top bun and serve.

    Hello, I saw this recipe on my FB feed and I had to try it. Since I didn't have a cast iron I cooked the burgers on my electric griddle and it formed the outer crust, and I prefer the griddle because as the burgers cook all the grease drains out. I am not a big burger eater but this came out delicious and my whole family loved them. I grilled the onions on the side, since we really don't like raw onions too much...thanks for sharing 🙂
