How To Make In-N-Out Animal Style Grilled Cheese Recipe

A vegetarian twist on the classic In-N-Out burger, this grilled cheese is loaded with caramelized onions, melted cheese, and special sauce.

Preparation: 15 minutes
Cooking: 25 minutes
Total: 40 minutes



  • 8 slices of bread
  • 4 tbsp of unsalted butter
  • 1 large yellow onion, sliced thin
  • 1/4 cup of mayonnaise
  • 2 tbsp of ketchup
  • 1 tbsp of yellow mustard
  • 1 tbsp of white vinegar
  • 2 cups of shredded cheddar cheese
  • Salt and black pepper


  1. In a skillet over medium-low heat, melt 2 tbsp of butter and add sliced onions. Cook, stirring occasionally for 20-25 minutes, until caramelized. Season with salt and black pepper and set aside.

  2. In a bowl, mix mayonnaise, ketchup, yellow mustard, and white vinegar to make the special sauce.

  3. Heat a griddle over medium heat and butter one side of each slice of bread. Place bread butter-side down on griddle and top with shredded cheddar cheese, caramelized onions, and a drizzle of special sauce. Top with another buttered slice of bread and grill until cheese is melted and bread is golden brown, about 3-4 minutes per side.

  4. Cut sandwiches in half and serve hot.
