For the Meatloaf
• Ground Beef – Main protein that provides structure and flavor; can use ground turkey or lamb for variety.

For the Cheese Sauce

Now that you have all the ingredients ready for your Mac and Cheese Meatloaf Casserole, let’s get cooking and enjoy this delightful dish together!
Step‑by‑Step Instructions for Mac and Cheese Meatloaf Casserole
Step 1: Preheat the Oven
Begin your mac and cheese meatloaf casserole by preheating your oven to 350°F (175°C). This ensures that your casserole will bake evenly and thoroughly. As the oven warms, prepare your baking dish by greasing it lightly with cooking spray or butter to prevent sticking and help achieve that perfect crust.
Step 2: Combine the Meat Mixture
In a large mixing bowl, combine your ground beef, finely chopped onion, breadcrumbs, egg, milk, salt, and pepper. Use your hands or a spoon to mix everything together until well incorporated. You want a slightly sticky mixture that holds together well. This mixture will form the base of your hearty mac and cheese meatloaf casserole.
Step 3: Shape and Bake the Meatloaf
Transfer the meat mixture into your greased baking dish, pressing it firmly to form an even layer. Smooth the top with a spatula for a uniform appearance. Bake this layer in the preheated oven for about 20 minutes, or until it begins to brown slightly on the edges and is firm to the touch—a sure sign it’s ready for the next steps.
Step 4: Cook the Macaroni
While your meatloaf is baking, cook the macaroni according to the package instructions until it’s al dente. This usually takes about 7-9 minutes. Drain the macaroni in a colander and set it aside. You want the pasta to still have a bit of bite, as it will absorb some moisture while baking in the casserole, combining beautifully with the creamy cheese sauce.
Step 5: Make the Cheese Sauce
In a medium saucepan over medium heat, melt the butter until bubbly. Gradually whisk in the flour, stirring continuously for about a minute until it forms a roux. Next, slowly add in the milk, whisking constantly to avoid lumps. Cook this mixture until it thickens, which should take around 3-5 minutes. Once thickened, add paprika, dry mustard, salt, and pepper, stirring well to incorporate.
Step 6: Incorporate the Cheese
Remove the saucepan from the heat and stir in your shredded cheese until fully melted and smooth. This creamy cheese sauce is the star of your mac and cheese meatloaf casserole! Next, fold in the cooked macaroni, ensuring each piece is coated with the deliciously rich sauce, creating that gooey texture everyone loves.
Step 7: Assemble the Casserole
Take the now-baked meatloaf out of the oven. Carefully pour the macaroni and cheese mixture over the top, spreading it evenly to ensure every bite has a little of everything. For an extra cheesy topping, sprinkle any remaining shredded cheese over the macaroni layer. This will create a beautiful, gooey top as it bakes.
Step 8: Final Bake
Return your assembled mac and cheese meatloaf casserole to the oven and bake for an additional 25 minutes. Look for the cheese to be melted, beautifully bubbly, and golden brown on top. This visual cue indicates the dish is ready and ensures that all the flavors have melded together beautifully.
Step 9: Rest Before Serving
Once the casserole is done baking, remove it from the oven and let it rest for about 10 minutes. This allows the layers to set slightly, making it easier to serve. After resting, slice into your mac and cheese meatloaf casserole and enjoy a heartwarming, comforting meal that your family will love!

Make Ahead Options
Preparing the Mac and Cheese Meatloaf Casserole ahead of time is a fantastic way to save precious minutes on busy weeknights! You can mix the meatloaf ingredients and press them into the baking dish up to 24 hours in advance—simply cover and refrigerate it until you’re ready to bake.

Mac and Cheese Meatloaf Casserole Recipe FAQs
How do I choose the best meat for my casserole?
Absolutely! When selecting meat, aim for high-quality ground beef that’s around 80% lean. This will help maintain juiciness and prevent the meatloaf from becoming dry. You can also experiment with ground turkey or lamb for a different flavor profile.
What’s the best way to store leftover casserole?
Very! Store your Mac and Cheese Meatloaf Casserole in an airtight container in the refrigerator for up to 3 days. Make sure the casserole has cooled completely before sealing it to preserve its freshness and flavors.
Can I freeze my casserole?
Definitely! To freeze, wrap the casserole tightly in plastic wrap, then cover it with aluminum foil to prevent freezer burn. It can be stored for up to 3 months. When you’re ready to enjoy it, defrost in the fridge overnight before reheating.
What should I do if my meatloaf is dry?
If you find that your meatloaf is dry, there are a couple of things you can do. First, ensure you’re using a good ratio of fat in the meat, ideally around 20%. Additionally, if you’ve managed to over-bake it, adding a splash of milk or broth while reheating can help reintroduce moisture.
Are there any dietary considerations for the casserole?
For sure! If you’re catering to dietary restrictions, consider substitutes like gluten-free breadcrumbs and plant-based milk to make it lactose-free. If anyone in your household has allergies, be sure to check all labels and opt for allergy-friendly cheese alternatives if needed.
How can I incorporate more vegetables?
Great question! Sneaking in veggies can be fun and nutritious. Finely chop spinach, bell peppers, or zucchini and mix them into the meatloaf or the cheese sauce. You can also layer cooked broccoli on top of the meatloaf before adding the macaroni to ensure every bite is filled with wholesome goodness.
