Ingredients

Scale
  • 1 lb ground beef

  • 2 cups uncooked macaroni

  • 2 cups shredded cheddar cheese (divided)

  • ½ cup diced onion

  • ½ cup breadcrumbs

  • 1 large egg

  • ¼ cup milk (for meatloaf)

  • 2 tablespoons butter

  • 2 tablespoons flour

  • 2 cups milk (for cheese sauce)

  • 1 teaspoon salt

  • ½ teaspoon black pepper

  • ½ teaspoon paprika

  • ½ teaspoon dry mustard

Instructions

  • Preheat the Oven
    Preheat your oven to 350°F (175°C) and lightly grease a baking dish.

  • Prepare the Meatloaf Layer
    In a large bowl, combine ground beef, diced onion, breadcrumbs, egg, ¼ cup milk, salt, and pepper. Mix until just combined.
    Press the mixture evenly into the prepared baking dish.

  • Bake the Meatloaf
    Bake for 20 minutes until partially cooked.

  • Cook the Macaroni
    While the meatloaf bakes, cook the macaroni according to package instructions. Drain and set aside.

  • Make the Cheese Sauce
    In a saucepan over medium heat, melt the butter. Stir in the flour and cook for 1 minute.
    Gradually whisk in 2 cups milk, stirring constantly until thickened. Season with paprika and dry mustard.
    Stir in most of the shredded cheddar cheese until smooth and melted.

  • Assemble the Casserole
    Mix the cooked macaroni with the cheese sauce.
    Spoon the mac and cheese evenly over the baked meatloaf layer. Sprinkle remaining cheese on top.

  • Final Bake
    Return to the oven and bake for 25 minutes, or until bubbly and lightly golden on top.

  • Serve
    Let rest for a few minutes before slicing and serving.

Notes

  • Don’t overmix the meatloaf to keep it tender and juicy.

  • Add veggies like peas, corn, or spinach to the mac and cheese for extra nutrition.

  • Switch up the cheese by using Monterey Jack, Colby, or a cheddar blend.

  • Make it ahead: Assemble the casserole, cover, and refrigerate up to 24 hours before baking.

  • Extra crispy top: Broil for 2–3 minutes at the end (watch closely).
