Ingredients for Mac and Cheese Meatloaf Casserole

For the meatloaf:

• 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
• 1/2 tsp paprika
• 1/2 tsp dry mustard

For the mac and cheese:

• 2 cups uncooked macaroni
• 2 tbsp butter
• 2 tbsp flour
• 2 cups milk
• 2 cups shredded cheddar cheese
• 1 tsp salt

These ingredients create a well-balanced dish where the meatloaf is savory and flavorful while the macaroni and cheese adds creaminess and indulgence.

Understanding the Ingredients

Ground beef forms the base of the meatloaf, providing protein, heartiness, and richness. Using 80/20 ground beef ensures the right balance of flavor and moisture.

Breadcrumbs and milk bind the meatloaf together, keeping it tender and preventing it from drying out.

Egg acts as a binder, giving the meatloaf structure while helping it hold together during baking.

Onion adds natural sweetness and depth of flavor, balancing the richness of the beef.

Salt, pepper, paprika, and dry mustard season the meatloaf, creating a flavorful foundation that complements the creamy macaroni and cheese.

Uncooked macaroni provides the base for the cheesy pasta layer. The pasta will cook in the oven as it bakes with the sauce, absorbing flavor and creating a tender texture.

Butter and flour form the roux for the cheese sauce, which thickens the milk into a creamy base that coats the pasta perfectly.

Milk and shredded cheddar cheese create the rich, creamy sauce essential to classic mac and cheese, adding indulgence and a comforting flavor that pairs beautifully with the savory meatloaf.

Preparation Method

Step 1: Preheat the oven
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter or cooking spray.

Step 2: Prepare the meatloaf mixture
In a large mixing bowl, combine ground beef, diced onion, breadcrumbs, egg, 1/4 cup milk, salt, pepper, paprika, and dry mustard. Mix gently until the ingredients are evenly incorporated. Avoid overmixing to keep the meatloaf tender.

Step 3: Shape the meatloaf
Spread the meat mixture evenly in the bottom of the prepared baking dish. Flatten gently so it forms an even layer that will support the mac and cheese topping.

Step 4: Cook the macaroni
Cook the macaroni according to package instructions until al dente. Drain and set aside.

Step 5: Make the cheese sauce
In a medium saucepan, melt butter over medium heat. Stir in flour and cook for 1–2 minutes, whisking constantly to form a smooth roux. Gradually whisk in 2 cups milk, continuing to stir until the mixture thickens. Remove from heat and stir in shredded cheddar cheese and 1 tsp salt until smooth.

Step 6: Combine pasta and cheese sauce
Add the cooked macaroni to the cheese sauce, stirring to coat the pasta evenly.

Step 7: Assemble the casserole
Pour the macaroni and cheese mixture over the meatloaf layer in the baking dish, spreading it evenly. Optionally, sprinkle additional shredded cheddar cheese on top for an extra golden, bubbly crust.

Step 8: Bake
Bake the casserole in the preheated oven for 25–30 minutes, or until the top is golden and bubbly, and the meatloaf is cooked through. A thermometer inserted into the center of the meatloaf should read at least 160°F (71°C).

Step 9: Rest and serve
Remove the casserole from the oven and let it rest for 5–10 minutes before serving. This allows the layers to set slightly, making it easier to cut and serve.

Tips for Perfect Mac and Cheese Meatloaf Casserole

• Use freshly shredded cheese for a smoother melt and better flavor.
• Avoid overmixing the meatloaf mixture to prevent a dense texture.
• Make sure the macaroni is al dente; it will cook slightly more in the oven.
• For extra flavor, add a pinch of smoked paprika or cayenne pepper to the cheese sauce.
• Resting the casserole before serving helps maintain its shape and prevents the cheese from separating.

Serving Suggestions

Serve the casserole with a side salad, roasted vegetables, or steamed green beans to balance the richness. For a comforting family dinner, pair it with garlic bread or dinner rolls. This casserole also works well as a make-ahead meal for busy weeknights, as leftovers reheat beautifully in the oven or microwave.

Storage and Make-Ahead Tips

Store any leftovers in an airtight container in the refrigerator for up to 3–4 days. Reheat in the oven at 350°F (175°C) to restore the creamy texture and melted cheese. You can also assemble the casserole ahead of time, cover it, and refrigerate before baking, making it perfect for meal prep or entertaining.
