What Is Mac and Cheese Meatloaf Casserole?

Mac and Cheese Meatloaf Casserole is exactly what it sounds like: a baked dish that combines a classic meatloaf base with a layer of creamy macaroni and cheese on top. Instead of serving these two comfort foods separately, they’re layered together and baked as one cohesive casserole.

The bottom layer is a traditional meatloaf mixture—ground beef, breadcrumbs, egg, onion, and seasonings—pressed into a baking dish and partially baked. On top goes homemade mac and cheese, made with a buttery roux and melted cheddar. Everything finishes baking together until hot, bubbly, and lightly golden.

The result? A fork-tender slice that gives you savory meatloaf and creamy mac and cheese in every bite.

Ingredient Tips for Best Results

Ground Beef

Use 80/20 ground beef for the best balance of flavor and moisture. Leaner beef can dry out, while fattier beef may release too much grease.

Cheese

Sharp cheddar gives the most flavor, but you can mix cheeses for extra depth. Monterey Jack, Colby, or even a little mozzarella work well.

Macaroni

Classic elbow macaroni is ideal, but shells or cavatappi also work because they hold onto the cheese sauce beautifully.

Breadcrumbs

Plain breadcrumbs are best so they don’t overpower the flavor. Panko works too for a lighter texture.

Step-by-Step Instructions

1. Preheat the Oven

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

2. Prepare the Meatloaf Layer

In a large bowl, combine the ground beef, diced onion, breadcrumbs, egg, ¼ cup milk, salt, and pepper. Mix gently until just combined—do not overmix.

Press the meat mixture evenly into the prepared baking dish, forming a compact but not dense layer.

3. Bake the Meatloaf

Bake the meatloaf layer for 20 minutes, just until it begins to set. This step ensures the meatloaf cooks evenly once the mac and cheese is added.

4. Cook the Macaroni

While the meatloaf bakes, cook the macaroni according to package instructions in salted water. Drain and set aside.

5. Make the Cheese Sauce

In a saucepan over medium heat, melt the butter. Whisk in the flour and cook for about 1 minute, forming a smooth roux.

Gradually whisk in the milk, stirring constantly until the sauce thickens. Season with paprika and dry mustard.

Stir in most of the shredded cheddar cheese until melted and smooth.

6. Assemble the Casserole

Mix the cooked macaroni with the cheese sauce until evenly coated.

Carefully spoon the mac and cheese over the partially baked meatloaf layer. Sprinkle the remaining cheese on top.

7. Final Bake

Return the casserole to the oven and bake for 25 minutes, until bubbly and lightly golden on top.

8. Rest and Serve

Let the casserole rest for 5–10 minutes before slicing. This helps it hold together when serving.

Pro Tips for Perfect Mac and Cheese Meatloaf Casserole

• Don’t overmix the meatloaf – Overmixing makes it dense and tough.

• Season generously – Pasta and meat both need seasoning to shine.

• Grate your own cheese – Pre-shredded cheese doesn’t melt as smoothly.

• Let it rest before slicing – This improves texture and presentation.

• Broil for a crispy top – Broil for 2–3 minutes at the end if desired.

Variations to Try

Cheesy Deluxe Version

Add cream cheese or a splash of heavy cream to the cheese sauce for extra richness.

Veggie-Packed Version

Mix peas, corn, spinach, or sautéed mushrooms into the mac and cheese layer.

BBQ Meatloaf Twist

Add a thin layer of BBQ sauce on top of the meatloaf before adding the mac and cheese.

Spicy Version

Add cayenne pepper or chopped jalapeños to the cheese sauce.

Different Proteins

Swap ground beef for ground turkey, chicken, or a beef-pork blend.
