For the Mac and Cheese
- Macaroni – The staple carb, contributing to the comforting texture. Preparation: Use 2 cups uncooked macaroni; adjust if necessary based on personal preference.

- Cheddar Cheese (2 cups) – Provides a rich, creamy flavor and gooey texture in the casserole. Substitution: Use a blend of cheeses for enhanced flavor.
- Butter – Used to create a roux for the cheese sauce. Together with flour, it makes the creamy base for the macaroni.

Step‑by‑Step Instructions for Mac and Cheese Meatloaf Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures that it’s hot enough to properly cook the Mac and Cheese Meatloaf Casserole once assembled. While the oven heats up, gather and prep your ingredients so everything is ready for the next steps.
Step 2: Prepare the Meatloaf Mixture
In a large mixing bowl, combine ground beef, finely diced onion, breadcrumbs, one egg, ¼ cup milk, and a generous pinch of salt and pepper. Use your hands or a spoon to mix until just combined, being careful not to overwork the meat. Once mixed, press this mixture evenly into a greased 9×13-inch baking dish to form the base of your casserole.
Step 3: Bake the Meatloaf
Place the meatloaf into your preheated oven and bake it for 20 minutes. This partially cooks the meatloaf, ensuring it will be moist and flavorful when combined with the macaroni and cheese. You’re looking for it to firm up slightly but not be fully cooked yet, so keep an eye on it!
Step 4: Cook the Macaroni
While the meatloaf bakes, cook the macaroni according to package instructions until al dente. Once cooked, drain the macaroni well and set it aside. This will serve as the delicious pasta layer that complements the savory meatloaf in your Mac and Cheese Meatloaf Casserole.
Step 5: Make the Cheese Sauce
In a medium saucepan over medium heat, melt 2 tablespoons of butter. Stir in 2 tablespoons of flour, cooking for about one minute until bubbly. Gradually whisk in 2 cups of milk, stirring until the mixture thickens. Remove from heat and incorporate salt, pepper, paprika, and 1.5 cups of shredded cheddar cheese until creamy and melted.
Step 6: Combine Macaroni with Cheese Sauce
Add the cooked macaroni to the cheese sauce, stirring gently until each piece is well-coated with that luscious, cheesy goodness. This will create the ultimate comfort layer for the Mac and Cheese Meatloaf Casserole. Spread the macaroni mixture evenly over the partially baked meatloaf in the dish.
Step 7: Top with Remaining Cheese
Sprinkle the remaining half cup of shredded cheddar cheese evenly over the macaroni layer. This will create a wonderfully creamy and gooey top layer that melts beautifully during the final bake. Make sure every inch is covered to maximize that cheesy flavor!
Step 8: Final Bake
Return the casserole to the oven and bake for an additional 25 minutes. You’ll know it’s done when the cheese on top is melted and bubbling, creating a beautiful golden crust. Let it cool for a few minutes before slicing, allowing all those incredible layers to set. Enjoy your Mac and Cheese Meatloaf Casserole!

Make Ahead Options
These Mac and Cheese Meatloaf Casserole preparations are perfect for busy home cooks looking to save time during the week! You can prepare the meatloaf mixture and layer it in the baking dish up to 24 hours in advance, ensuring to cover it tightly with plastic wrap to maintain freshness. The cheese sauce can also be made and refrigerated for up to 3 days—just reheat it gently before mixing it with the cooked macaroni. When you’re ready to serve, simply assemble the casserole and bake it directly from the fridge, adding an extra 5-10 minutes to the baking time as needed. This way, you’ll have a delightful dish that’s just as delicious, without the last-minute rush!
