Instructions
 

Preparation

  • Preheat your oven to 350 degrees F (175 degrees C).

  • Press the mixture into the bottom of a greased baking dish.
  • Bake the meatloaf in the preheated oven for about 20 minutes.

Cooking

  • In a medium saucepan, melt butter over medium heat. Stir in flour and cook for about one minute.
  • Gradually whisk in milk and cook until thickened.
  • Stir in salt, pepper, paprika, and dry mustard. Add in 1 1/2 cups of shredded cheese until melted.
  • Stir the cooked macaroni into the cheese sauce until well coated.
  • Pour this mixture over the partially cooked meatloaf. Sprinkle any remaining cheese on top.
  • Return to the oven and bake for an additional 25 minutes, or until cheese is melted and bubbly.

Notes

Serve hot from the oven, cut into squares for easy serving. Pairs well with a side salad or steamed vegetables. Store leftovers tightly covered in the refrigerator for up to 3 days or freeze for longer storage.
