Copycat In-N-Out Animal Style Burger

Report
This Copycat In-N-Out Animal Style Burger recipe recreates the well-known fast food favorite with caramelized onions sautéed in butter, mustard-spread beef patties, American cheese, crisp iceberg lettuce, and a tangy house sauce. The patties are smashed thin and cooked quickly to create a juicy interior with flavorful browning. The special sauce combines mayonnaise, ketchup, pickle relish, and vinegar to complement the savory components, making a layered flavor profile typical of the iconic burger.

Description

The Copycat In-N-Out Animal Style Burger brings together fresh ground beef formed into thin patties pressed and cooked on a hot skillet to develop a crisp edge while keeping the center juicy. Butter-sautéed onions add sweetness and richness to each bite, contrasting with layers of melted American cheese and mustard-spread patties. The sauce, made of mayonnaise, ketchup, pickle relish, and vinegar, adds a creamy and tart note that balances the savory flavors. The burger is topped with crisp iceberg lettuce and fresh tomato slices on lightly toasted hamburger buns, delivering textural variety and fresh elements.

The preparation includes toasting the buns on the griddle, ensuring a warm base to hold the juicy patties and toppings. This burger works well as a satisfying main dish, perfect for a casual meal where a flavorful, saucy burger is desired. Serving immediately helps enjoy the contrast of textures and temperatures at their best.

Leftover patties can be kept refrigerated in an airtight container for up to a week, but the burger is recommended to be served fresh to maintain quality. Reheating may diminish the texture of the patties and wilt the vegetables.

Ingredients

Servings
  • 1 pound ground beef 80/20 (lean to fat ratio
  • 2 tsp olive oil
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • 4 tablespoons mustard
  • 1 tablespoon butter
  • 1 white onion chopped
  • 8 lices American cheese
  • 1 tomato sliced, large
  • 8 iceberg lettuce leaves
  • 4 Hamburger Bun

FOR THE SAUCE:

  • 1/2 cup mayonnaise
  • ¼ cup ketchup
  • 2 Tablespoon pickle relish sweet
  • 2 Tablespoon white vinegar

Instructions

  1. Mix the sauce ingredients together in a small bowl.
  2. Melt the butter in a large skillet (or cast iron pan) over medium high heat.  Then top the melted butter with the chopped onions.  Sauté the onions in the butter until they are caramelized (3-5 minutes).  Remove the onions from the skillet and set aside.
  3. Form the ground beef into 4 balls approximately ¼ pound each.
  4. Drizzle the olive oil on a skillet, cast iron pan or griddle over medium high heat.
  5. Place the buns on the preheated pan for 2 minutes to toast them and then set them aside while you prepare the beef.
  6. Then place the beef balls on the pan. Then top each one with a piece on parchment paper and firmly press down to smash the beef into a thin patty with either a burger press or a large spatula and then discard the parchment paper. Season the patties with salt and pepper.
  7. Cook the patties for 2 minutes until the juices in the beef start to raise to the top and the color starts to change. While the patties are cooking, top each of the patties with 1 tablespoon of mustard on the raw side.  Then scrape under the patty to get under the caramelized parts and flip the patty. Once flipped, do not smash down the patties again. Cook for 1 more minute and place 2 pieces of cheese on each of the patties.  Cook for 1 more minute to allow the cheese to melt.
  8. Then it’s time to assemble your burgers. Spread the sauce on the top and bottom of the bun. Then top the bottom bun with the lettuce, tomatoes, patty and sauté onions.  Then the top bun.
  9. Then the burgers are ready to enjoy!

Notes

  • Store leftover cooked patties in an airtight container up to 1 week in the fridge.
  • For best results, serve the burger fresh to enjoy the crispy edges and juicy center of the patties.
