  • 1 cup dill pickles, chopped
  • 2 cups cheddar cheese, shredded
  • 1 cup mozzarella cheese, shredded
  • 1/4 cup mayonnaise
  • 1/4 cup ketchup
  • 2 tbsp yellow mustard
  • 1 tbsp Worcestershire sauce
  • 1 tsp salt
  • 1/2 tsp pepper

  • 4 hamburger buns, torn into bite-sized pieces

Instructions

  1. Preheat Oven: Begin by preheating your oven to 350°F (175°C) to prepare for baking the casserole.
  2. Cook Ground Beef: In a large skillet over medium heat, cook the ground beef until browned. Remove excess fat to avoid greasiness.
  3. Sauté Onions and Garlic: Add the diced onions and minced garlic to the skillet and sauté until they are softened and fragrant, melding with the beef.
  4. Mix Seasonings and Condiments: Stir in salt, pepper, Worcestershire sauce, mayonnaise, ketchup, yellow mustard, and the beaten eggs into the beef mixture. Mix everything thoroughly to evenly distribute flavors.
  5. Prepare Baking Dish: Spray a 9×13 inch baking dish with cooking spray to prevent sticking.
  6. Layer the Casserole – First Layer: Spread half of the beef mixture evenly into the bottom of the baking dish.
  7. Add Pickles and Cheese: Sprinkle the chopped dill pickles over the beef, then layer half of the shredded cheddar and mozzarella cheeses on top.
  8. Add Bread Pieces: Tear the hamburger buns into bite-sized pieces and scatter them evenly over the cheese layer.
  9. Final Beef and Cheese Layer: Top the bun pieces with the remaining cheese and then spread the rest of the beef mixture evenly over everything.
  10. Bake: Place the casserole in the preheated oven and bake for 25-30 minutes or until the top is golden brown and the cheese is bubbly.
  11. Rest and Garnish: Let the casserole rest a few minutes after baking, then garnish with optional shredded lettuce, diced tomatoes, extra pickles, and additional ketchup or mustard as desired before serving.

Notes

  • Use fresh hamburger buns for the best texture in the casserole. Day-old buns can also work if torn into properly sized pieces.
  • Feel free to adjust cheese types—Swiss or American cheese can be interesting substitutes.
  • If preferred, reduce salt to lower sodium content, especially with canned or processed pickles.
  • Letting the casserole rest after baking helps it set and makes it easier to serve.
  • For a spicier version, add a dash of hot sauce or some diced jalapeños to the beef mixture.
