Ingredients

Meatloaf Layer

• 1 lb ground beef
• 1/2 cup diced onion
• 1/2 cup breadcrumbs
• 1 large egg
• 1/4 cup milk
• 1 tsp salt
• 1/2 tsp pepper

Mac and Cheese Layer

• 2 cups uncooked macaroni
• 2 cups shredded cheddar cheese
• 2 tbsp butter
• 2 tbsp flour
• 2 cups milk
• 1/2 tsp paprika
• 1/2 tsp dry mustard
• 1/2 tsp pepper
• Additional salt to taste

Substitution Options

• Swap ground beef with ground turkey for a lighter version.
• Use gluten-free breadcrumbs and pasta if needed.
• Any melting cheese works well, including Colby Jack or mozzarella.

Step-by-Step Instructions

1. Preheat and start the meatloaf
   Preheat your oven to 350°F (175°C). In a large bowl, mix ground beef, diced onion, breadcrumbs, egg, milk, salt, and pepper until fully combined but not overmixed.
2. Shape and bake
   Press the meat mixture firmly into a greased baking dish. Bake for 20 minutes to partially cook the meatloaf before adding the macaroni and cheese layer.
3. Cook the macaroni
   Prepare the macaroni according to package directions. Drain well and set aside. Avoid overcooking the pasta, as it will continue to soften in the oven.
4. Make the cheese sauce
   Melt butter in a medium saucepan over medium heat. Add flour and stir for one minute to create a smooth roux. Gradually whisk in milk until the sauce begins to thicken, then season with paprika, dry mustard, pepper, and salt.
5. Melt the cheddar
   Add shredded cheddar cheese to the hot sauce, stirring until smooth and fully melted. If the sauce becomes too thick, add one to two tablespoons of milk.
6. Combine and layer
   Stir the cooked macaroni into the cheese sauce until evenly coated. Pour the mixture on top of the partially baked meatloaf and spread it into an even layer. Sprinkle extra cheddar over the top for a crisp finish.
7. Final bake
   Return the dish to the oven and bake for an additional 25 minutes, or until the top is bubbly and lightly golden. Let the casserole rest for five minutes before slicing.

Expert Tips for Success

• Press the meatloaf firmly into the pan to ensure it cooks evenly.
• For the smoothest cheese sauce, add the milk slowly while whisking continuously.
• Let the casserole rest briefly after baking to help the layers set for cleaner slices.
• Use freshly shredded cheese for better melting and flavor.

FAQs

Can I make this casserole ahead of time?
Yes, you can assemble it up to one day in advance and refrigerate. Add five extra minutes to the final bake to ensure full heating.

Can I use pre-shredded cheese?
Yes, but freshly shredded cheese melts more smoothly. Pre-shredded cheese sometimes contains starch that affects sauce texture.

Can I double the recipe for a crowd?
You can double it and use a larger baking dish. Increase the first bake by five minutes to ensure the meatloaf layer cooks evenly.

Can I make it without breadcrumbs?
You can replace breadcrumbs with crushed crackers or oats. These absorb moisture well and maintain the meatloaf structure.

Can this be made in individual ramekins?
Yes, but reduce the final bake to 15–20 minutes. Smaller portions heat more quickly.
