This Copycat In and Out Burger Animal Style Recipe is easy to make at home. Enjoy caramelized onions, sweet pickles and a special sauce. It all comes together for a delicious meal.
Mix the sauce ingredients together in a small bowl.
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.
Form the ground beef into 4 balls approximately ¼ pound each.
Drizzle the olive oil on a skillet, cast iron pan or griddle over medium high heat.
Place the buns on the preheated pan for 2 minutes to toast them and then set them aside while you prepare the beef.
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.
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.
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.
Then the burgers are ready to enjoy!
Notes
These burgers are best served fresh, but you can store the leftover patties in an airtight container for up to 1 week.
