How to Make Mac and Cheese Meatloaf Casserole

Now, let’s talk about how to make this amazing dish. The steps are simple and straightforward, so even novice cooks can follow along easily.

Ingredients:

1 lb ground beef
2 cups uncooked macaroni
2 cups shredded cheddar cheese
1/2 cup diced onion
1/2 cup breadcrumbs
1 large egg
1/4 cup milk (for meatloaf)
2 tbsp butter (for cheese sauce)
2 cups milk (for cheese sauce)
1 tsp salt
1/2 tsp pepper
1/2 tsp paprika
1/2 tsp dry mustard
2 tbsp flour

Directions:

Preheat your oven to 350°F (175°C). This step is essential for even cooking and a nicely browned top.
In a mixing bowl, combine the ground beef, diced onion, breadcrumbs, egg, 1/4 cup of milk, salt, and pepper. Mix everything well. Use your hands or a spoon to ensure it is evenly mixed. Once done, press the mixture into a greased baking dish to form the meatloaf layer.
Bake the meatloaf for 20 minutes. This helps it get a nice sear and begin cooking through.
While the meatloaf bakes, cook the macaroni according to the package directions. Drain the macaroni and set it aside when it is done. It’s essential to ensure the pasta is cooked but still slightly firm, as it will bake further in the casserole.
For the cheese sauce, melt the butter in a saucepan over medium heat. Once the butter is melted, stir in the flour and cook for one minute. This step helps create a roux, which adds thickness to your cheese sauce.
Gradually whisk in the 2 cups of milk until the mixture thickens. Keep stirring to avoid lumps in the sauce. Once thickened, season the sauce with salt, pepper, paprika, and dry mustard.
Stir in the shredded cheddar cheese until it melts completely, creating a smooth and cheesy sauce.
Combine the cooked macaroni with the cheese sauce, mixing until the pasta is well coated.
Pour the cheesy macaroni mixture evenly over the baked meatloaf layer in the dish.
Top the casserole with any remaining shredded cheese for added gooeyness and richness.
Bake for an additional 25 minutes or until the top is bubbly and golden.
