Equipment

Ingredients

  • 1 pound bag frozen French fries restaurant style
  • 1 tablespoon olive oil or melted butter
  • 1 cup yellow onion finely diced
  • ½ teaspoon salt
  • 7 slices American cheese

For the In-N-Out Sauce

  • ½ cup mayonnaise
  • ⅓ cup ketchup
  • 2 tablespoons sweet relish
  • 1 tablespoon yellow mustard

Optional Garnishes

Instructions

Cook the Fries

  • Cook the fries according to package directions. You want them extra crispy, so they don't get soggy when topped with cheese and sauce.

Prepare the Sauce

  • Mix all the sauce ingredients in a bowl until smooth.
  • Refrigerate until ready to serve.

Cook the Onion

  • Heat olive oil in a skillet over medium heat.
  • Add onion and salt and cook for 7-10 minutes, stirring occasionally. Once the onions are browned, set aside.

Broil the Animal Fries

  • Preheat the oven to broil on high and transfer the fries onto a baking sheet.
  • Add 7 slices of American cheese on top of the cooked French fries and broil for a few minutes, just until the cheese melts, watching closely.
  • Remove from the oven.

Add the Toppings

  • Spread most of the In-N-Out sauce over the melted cheese, and top with the cooked onions.

Garnish and Serve

  • Grind over a little black pepper and/or add fresh chopped parsley, if liked.
  • Serve immediately with the reserved sauce on the side.

Notes

  • Sauce amount: The recipe makes about a cup of sauce, so you may have extra for dipping.
  • Cheese coverage: Tear the slices as needed to cover gaps between the fries.
  • Frozen fry brands: Make sure to follow the package directions because cooking temperatures and times vary.
  • Parsley garnish: Parsley is optional and isn’t part of the original restaurant topping. I like the pop of color it adds but you can omit it if preferred.
