Ingredients:
- 2 lbs ground beef (I use 80/20 for that authentic fast food flavor)
- 1 medium onion, finely diced (about 1 cup)
- 3 cloves garlic, minced (or more, I won’t judge)
- 2 tablespoons Worcestershire sauce
- 1 tablespoon yellow mustard
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 6 hamburger buns, torn into bite-sized pieces (stale ones actually work better!)
- 2 tablespoons butter, melted
- 1 teaspoon sesame seeds
- 1/2 teaspoon garlic powder
- 1 cup mayonnaise (full fat is best here)
- 1/4 cup ketchup
- 2 tablespoons sweet pickle relish (the secret ingredient!)
- 1 tablespoon yellow mustard
- 1 tablespoon white vinegar
- 1 teaspoon sugar
- 1 teaspoon paprika
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 2 cups shredded cheddar cheese (the orange kind for that classic look)
- 1 cup shredded lettuce
- 1/2 cup dill pickles, chopped
- 1/4 cup diced onion
- 8 slices American cheese (yes, the plastic-wrapped kind)
Method:
Step 1: Prepare the Ground Beef Mixture
In a large skillet over medium heat, brown the ground beef with the diced onion and minced garlic. Cook until the meat is no longer pink, about 7-10 minutes. Drain excess fat, then stir in Worcestershire sauce, mustard, salt, black pepper, garlic powder, and onion powder. Mix until well combined.
Step 2: Toast the Bun Pieces
In a mixing bowl, combine the torn hamburger buns with melted butter, sesame seeds, and a sprinkle of garlic powder. Toss until the buns are well-coated. Set aside.
Step 3: Create the Sauce
In another bowl, whisk together the mayonnaise, ketchup, sweet pickle relish, yellow mustard, white vinegar, sugar, paprika, and the remaining garlic and onion powders to create a creamy, tangy sauce.
Step 4: Layer the Casserole
Preheat your oven to 350°F (175°C). In a greased 9×13 inch baking dish, spread half of the ground beef mixture on the bottom. Add half of the bun pieces, followed by half of the sauce. Sprinkle with 1 cup of shredded cheddar cheese. Repeat layers, finishing with a rich topping of the remaining cheese.
Step 5: Bake to Perfection
Cover the dish with aluminum foil and bake for 25 minutes. Remove the foil, then bake for an additional 10 minutes or until the cheese is bubbly and slightly golden.
Step 6: Garnish and Serve
Once out of the oven, let the casserole cool for a few minutes. Top with shredded lettuce, dill pickles, and diced onions for that fresh crunch. Serve hot and watch it disappear!
Serving Suggestions & Pairings

Storage & Leftovers Guide
Refrigerate any leftovers in an airtight container for up to 3-4 days. You can reheat in the oven at 350°F until warmed through, or in the microwave for quick servings.
