Step‑by‑Step Instructions for Mac and Cheese Meatloaf Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). Meanwhile, grease a medium-sized baking dish, as this is where your Mac and Cheese Meatloaf Casserole will come to life! Set the dish aside and gather the rest of your ingredients to ensure a smooth cooking process.
Step 2: Mix the Meatloaf
In a large mixing bowl, combine ground beef, finely chopped onion, breadcrumbs, egg, milk, salt, and pepper. Use your hands or a sturdy spoon to blend everything until well combined. Make sure the mixture is cohesive but avoid overworking it. Once ready, press the mixture evenly into the greased baking dish.
Step 3: Bake the Meatloaf
Place the baking dish in the preheated oven and bake for 20 minutes. You’ll know it’s ready when the edges are browned, and juices run clear. This step forms the savory base for your Mac and Cheese Meatloaf Casserole, so keep an eye on it as it cooks!
Step 4: Cook the Macaroni
While the meatloaf is baking, cook the macaroni according to package instructions, aiming for an al dente texture since it will continue to cook later. Once cooked, drain the pasta and set it aside to cool slightly. This will be the creamy heart of your casserole.
Step 5: Create the Cheese Sauce
In a saucepan over medium heat, melt the butter, then stir in the flour to create a roux. Gradually whisk in milk while stirring constantly until the mixture thickens, about 3–5 minutes. The sauce should be thick enough to coat a spoon. This rich cheese sauce will elevate your Mac and Cheese Meatloaf Casserole.
Step 6: Add Flavorful Seasonings
Once thickened, stir in paprika, dry mustard, and your shredded cheese of choice, mixing until the cheese fully melts and incorporates into the sauce. Taste the sauce and adjust seasoning if necessary; it should be creamy and flavorful, ready to grace your casserole.
Step 7: Combine Pasta and Sauce
Fold the drained macaroni into the cheese sauce, ensuring every bite is coated with that luscious flavor. This cheesy mixture will overflow atop the meatloaf, creating a delightful contrast in textures for your Mac and Cheese Meatloaf Casserole.
Step 8: Assemble and Bake
Pour the cheese-coated macaroni over the baked meatloaf layer. Spread it evenly to ensure every piece has a generous portion. Finally, sprinkle any remaining shredded cheese on top, enhancing the casserole’s gooey goodness as it bakes.
Step 9: Final Bake
Put your assembled Mac and Cheese Meatloaf Casserole back in the oven for an additional 25 minutes. Look for a bubbling top and a light golden color indicating that the cheese has melted beautifully. You can also broil for a minute or so for an extra crispy finish, but watch it closely!
Step 10: Cool and Serve
Once baked to perfection, remove the casserole from the oven and let it rest for about 10 minutes. This resting time makes cutting and serving easier. Get ready to enjoy the flavorful layers of your Mac and Cheese Meatloaf Casserole with family or friends!

Make Ahead Options
These Mac and Cheese Meatloaf Casserole make ahead options are a lifesaver for busy weeknights! You can prepare the meatloaf mixture (ground beef, onion, breadcrumbs, egg, milk, salt, and pepper) up to 24 hours in advance; just cover it tightly and refrigerate to keep it fresh. For even more convenience, cook the macaroni and cheese sauce ahead, allowing both components to cool before storing separately. When you’re ready to serve, simply layer the macaroni atop the meatloaf and bake as directed, adding an extra few minutes if stored in the fridge. This method ensures your casserole is just as delicious, saving you valuable time while still satisfying your family’s cravings!

Mac and Cheese Meatloaf Casserole Recipe FAQs
What should I look for when choosing ground beef for this recipe?
When selecting ground beef for your Mac and Cheese Meatloaf Casserole, look for meat with a balance of lean and fat, ideally around 80/20. This ratio keeps your meatloaf moist and flavorful. Avoid any packages with excessive dark spots or odors, as they could indicate spoilage. Fresh meat should feel firm to the touch and have a bright red color.
How should I store leftovers from the casserole?
Store any leftover Mac and Cheese Meatloaf Casserole in an airtight container in the refrigerator for up to 3 days. Make sure it cools down to room temperature before sealing it up. When you’re ready to enjoy the leftovers, simply reheat them in the microwave or oven until heated through. This dish tastes just as delightful even on the second day!
Can I freeze the Mac and Cheese Meatloaf Casserole?
Absolutely! If you want to freeze the casserole, I recommend wrapping it tightly in plastic wrap and then in aluminum foil to prevent freezer burn. It can be stored in the freezer for up to 3 months. Just remember to label it with the date! When you’re ready to cook it, thaw it overnight in the fridge before baking at 350°F (175°C) for about 30-40 minutes until heated through.
What if my cheese sauce isn’t thickening properly?
No worries! If your cheese sauce isn’t thickening as expected, make sure you are cooking the roux long enough before adding the milk—about 1-2 minutes should suffice. If it still seems too runny, you can mix an additional tablespoon of flour with a little bit of cold milk in a separate bowl to create a slurry. Gradually whisk this into the simmering cheese sauce on medium heat until it thickens.
Is there a way to make this casserole dairy-free?
Absolutely! To make a dairy-free version of your Mac and Cheese Meatloaf Casserole, use plant-based ground meat or lentils for the meatloaf mixture. For the cheese sauce, swap out regular milk for unsweetened almond milk or a dairy-free milk alternative, and use vegan cheese or nutritional yeast instead of shredded cheese. The flavors will still come together beautifully while accommodating your dietary needs!
