Ingredients:

1 lb lean ground beef
1 cup yellow onion, diced
1/2 cup real bacon bits
1/4 cup mayonnaise
1/4 cup ketchup
1 tbsp yellow mustard
1/2 tsp salt
1/2 tsp black pepper
2 tsp onion powder
12 slices white or whole wheat bread
1/2 cup margarine or butter, softened
4 cups shredded mozzarella and cheddar cheese blend

Preparing the Beef and Bacon Mixture

The first step in creating our delicious Beef Bacon Cheeseburger Grilled Cheese Casserole is to get the savory foundation ready. In a large skillet over medium-high heat, add the 1 lb of lean ground beef. Break it apart with a spatula and cook until it’s browned, ensuring there are no pink pieces remaining. Once the beef is fully cooked, carefully drain off any excess grease. This is an important step to prevent the casserole from becoming oily.

Next, add the 1 cup of diced yellow onion to the same skillet with the browned beef. Sauté the onions with the beef for about 5-7 minutes, or until they become softened and translucent. The gentle caramelization of the onions will add a wonderful depth of flavor to the entire casserole. After the onions have softened, stir in the 1/2 cup of real bacon bits. These bits are a fantastic shortcut for that smoky, crispy bacon flavor without the fuss of cooking actual bacon strips. Cook for another 2 minutes, allowing the bacon bits to warm through and mingle with the beef and onion mixture.

Now, it’s time to build the flavor profile of our cheeseburger filling. Reduce the heat to low. Add the 1/4 cup of mayonnaise, 1/4 cup of ketchup, and 1 tbsp of yellow mustard to the skillet. Stir everything together until the ground beef, onions, and bacon bits are thoroughly coated in this creamy, tangy sauce. This combination of condiments is reminiscent of your favorite cheeseburger sauce, bringing that familiar and comforting taste to our casserole. Season this mixture with 1/2 tsp of salt, 1/2 tsp of black pepper, and 2 tsp of onion powder. Mix well to ensure the seasonings are evenly distributed. Cook for another 2-3 minutes on low heat, allowing the flavors to meld together beautifully. Remove the skillet from the heat.

Assembling the Casserole

With our flavorful beef and bacon mixture ready, we can move on to assembling the Beef Bacon Cheeseburger Grilled Cheese Casserole. Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish. This will prevent sticking and make for easier serving.

Now, let’s prepare the bread. Lay out the 12 slices of white or whole wheat bread on a clean surface. We’re going to create a cheesy bread layer. Take half of the shredded mozzarella and cheddar cheese blend (approximately 2 cups) and sprinkle it evenly over 6 of the bread slices. These will act as the bottom layer of our bread “crust.”

Next, carefully spoon the prepared beef and bacon mixture evenly over the cheese-covered bread slices. Make sure to distribute the meat and onion mixture as evenly as possible, so each bite of the casserole has a good balance of flavors. Don’t be afraid to spread it right to the edges.

Now, it’s time for the second layer of cheese. Sprinkle the remaining 2 cups of shredded mozzarella and cheddar cheese blend over the beef and bacon mixture. This generous layer of cheese will become wonderfully gooey and melted during baking, creating that signature cheeseburger experience.

Finally, place the remaining 6 slices of bread on top of the cheese layer, completing the sandwich structure of our casserole.

Preparing the Topping and Baking

The final touch before baking is to create that golden-brown, buttery crust that mimics a perfectly grilled cheese sandwich. In a small bowl, combine the 1/2 cup of softened margarine or butter. Using a pastry brush or the back of a spoon, spread a generous layer of the softened margarine or butter evenly over the top of each bread slice. This is what will give our Beef Bacon Cheeseburger Grilled Cheese Casserole that irresistible grilled cheese finish. Make sure to get good coverage for a consistent golden color.

Once your casserole is assembled and topped with butter, cover the baking dish tightly with aluminum foil. This helps the casserole cook evenly and prevents the top from browning too quickly. Place the covered casserole into the preheated oven and bake for 25 minutes.

After 25 minutes, carefully remove the aluminum foil from the baking dish. Continue baking, uncovered, for another 15-20 minutes, or until the top of the casserole is beautifully golden brown and the cheese is melted and bubbly. You’ll notice the edges of the bread will become delightfully crispy, and the cheese will be oozing out in delicious pockets. The aroma filling your kitchen at this point will be absolutely divine!

Allow the Beef Bacon Cheeseburger Grilled Cheese Casserole to rest for about 5-10 minutes before slicing and serving. This resting period allows the casserole to set slightly, making it easier to cut into neat portions and ensuring the molten cheese doesn’t run everywhere. Serve hot and enjoy the comforting, familiar flavors of a cheeseburger transformed into a hearty, crowd-pleasing casserole.

Frequently Asked Questions:

Can I make this ahead of time?

Absolutely! You can assemble the entire casserole, minus the very top layer of bread if you’re doing a distinct bread topping, and refrigerate it for up to 24 hours. For best results when reheating, allow it to come to room temperature for about 30 minutes before baking, and you might need to add a few extra minutes to the baking time.

What kind of bread works best?

A sturdy bread is ideal to hold up to the fillings and baking. Sourdough, challah, or even a thick-cut white bread are excellent choices. Avoid very soft or thinly sliced breads, as they might become too soggy.
