Bacon Cheeseburger Grilled Cheese Casserole combines two comfort-food ideas in a 9-by-13-inch dish. Buttered sandwich bread surrounds seasoned ground beef, bacon, familiar burger condiments, and four cups of mozzarella-cheddar blend before baking to a crisp golden top.

The casserole serves 8 in 44 minutes, with 20 minutes of preparation and 24 minutes of cooking. Lean beef and thorough draining protect the bread layers from excess grease.

The filling needs 1 pound lean ground beef, 1 cup diced yellow onion, ½ cup real bacon bits, ¼ cup mayonnaise, ¼ cup ketchup, 1 tablespoon yellow mustard, ½ teaspoon salt, ½ teaspoon black pepper, and 2 teaspoons onion powder.

For assembly, use 12 slices white or whole-wheat sandwich bread, ½ cup softened margarine or butter, and 4 cups shredded mozzarella-and-cheddar cheese blend. These amounts make one large casserole with 8 servings.

The ultimate comfort food mashup with layers of bread, cheeseburger filling, and melted cheese baked to golden perfection.

Ingredients You'll Need

  • Cheeseburger Filling

  • Casserole Assembly

How to Make It

1.

1. Prep and Start the Beef: Preheat your oven to 400°F and grease a 9x13 inch baking dish. Heat a large skillet over medium-high heat and add the ground beef with a small dab of butter. Cook the beef, breaking it up into small crumbles as it browns - this takes about 6-8 minutes.

2.

2. Add Onions and Season: Once the beef is cooked through, drain any excess grease. Add the diced onions to the pan and cook for another 3-4 minutes, stirring occasionally, until the onions start to soften and become fragrant.

3.

3. Create the Cheeseburger Mixture: Remove the pan from heat and stir in the bacon bits, mayo, ketchup, mustard, salt, pepper, and onion powder. Mix everything together until well combined - this creates that classic cheeseburger flavor throughout the filling.

4.

4. Prepare the Bottom Layer: Spread 6 slices of bread with half the margarine, then cut each slice in half. Place these pieces margarine-side down in your greased baking dish, creating the bottom layer. Sprinkle 2 cups of the cheese mixture over the bread.

5.

5. Add the Filling: Spoon the beef mixture evenly over the cheese layer, spreading it out to cover the bread completely. Top with the remaining 2 cups of cheese - this creates those gooey, melty layers that make this casserole so amazing.

6.

6. Top and Bake: Spread the remaining 6 slices of bread with the rest of the margarine and cut them in half. Place these pieces margarine-side up on top of the casserole. Bake for 20-24 minutes until the top is golden brown and crispy.

7.

7. Serve Hot: Let the casserole rest for about 5 minutes before cutting - this helps it hold together better. Serve hot and watch everyone dig into this comfort food masterpiece!
