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 temperature ensures your Mac and Cheese Meatloaf Casserole bakes evenly, allowing the meatloaf to form a delicious crust while the cheese sauce maintains its creamy consistency. Make sure to set a timer so you’re ready when it’s time to bake!
Step 2: Prepare the Meatloaf Mixture
In a large mixing bowl, combine 1 pound of ground beef, 1 finely chopped onion, 1 cup of breadcrumbs, 1 beaten egg, ½ cup of milk, and a generous sprinkle of salt and pepper. Use clean hands or a wooden spoon to mix until all ingredients are well incorporated, creating a flavorful meatloaf base that’s moist and delicious.
Step 3: Form the Meatloaf
Transfer the meatloaf mixture into a greased baking dish, pressing it down firmly to form a cohesive loaf. The structure is crucial, as it will hold the layers together in your Mac and Cheese Meatloaf Casserole. Bake in your preheated oven for 20 minutes, until the edges begin to brown slightly and the meatloaf is set.
Step 4: Cook the Macaroni
While the meatloaf is baking, bring a pot of salted water to a boil and cook 2 cups of macaroni according to package directions until al dente. Once cooked, drain the pasta and set it aside, allowing it to cool slightly. This will create a perfect cheesy layer that won’t become mushy in the casserole.
Step 5: Make the Cheese Sauce
In a medium saucepan over medium heat, melt 4 tablespoons of butter. Once melted, whisk in ¼ cup of flour to form a roux, cooking for about 1 minute. Gradually whisk in 2 cups of milk, stirring constantly until the mixture thickens and bubbles. Add salt, pepper, 1 teaspoon of paprika, and 1 teaspoon of dry mustard, then mix in 2 cups of shredded cheese until fully melted and creamy.
Step 6: Combine the Pasta and Cheese Sauce
In a large bowl, combine the cooked macaroni with the prepared cheese sauce, stirring until the pasta is completely coated. This layer of cheesy goodness is what makes your Mac and Cheese Meatloaf Casserole truly irresistible! Ensure every piece is enveloped in that creamy sauce for maximum flavor.
Step 7: Assemble the Casserole
Carefully pour the macaroni and cheese mixture over the pre-baked meatloaf in the baking dish, spreading it out evenly. To add an extra touch of cheesiness, sprinkle any remaining shredded cheese over the top. This will create a beautifully melty layer as it bakes.
Step 8: Final Bake
Return the assembled casserole to the oven and bake for an additional 25 minutes. You’ll know it’s ready when the cheese on top is bubbly and golden, creating a perfectly appetizing finish to your Mac and Cheese Meatloaf Casserole. Let it rest for a few minutes before serving to allow the layers to set.

Storage Tips for Mac and Cheese Meatloaf Casserole
Fridge: Store leftovers in an airtight container for up to 3 days. Reheat portions in the microwave or oven until warmed through for the best flavor.
Freezer: To freeze, cool completely, then wrap tightly in plastic wrap and aluminum foil. The casserole can be frozen for up to 3 months. Thaw overnight in the fridge before reheating.
Reheating: When reheating, add a splash of milk if the casserole seems dry. Warm in the oven at 350°F (175°C) until heated evenly and cheese is melty.
Tip: The flavorful layers of the Mac and Cheese Meatloaf Casserole can sometimes taste even better the next day!

Mac and Cheese Meatloaf Casserole Recipe FAQs
What kind of meat can I use in this casserole?
Absolutely! While the recipe calls for ground beef, you can easily substitute with ground turkey or lamb for a different flavor profile. If you’re aiming for a meatless option, consider using plant-based ground meat or firm tofu crumbled up for a vegetarian twist.
How should I store leftovers?
To store your delicious Mac and Cheese Meatloaf Casserole, place any leftovers in an airtight container in the fridge, where they will stay fresh for up to 3 days. If you’re anything like me, you’ll find that the flavors meld wonderfully overnight!
Can I freeze the casserole?

How do I reheat the casserole properly?
When reheating, sprinkle a little splash of milk over the casserole to keep it moist. Preheat your oven to 350°F (175°C), then place the casserole in the oven and warm it until heated through and the cheese is melty again, about 20-25 minutes. If you’re in a hurry, a microwave will work too—just cover it to prevent drying out!
Is this casserole safe for my pet or people with allergies?
For pets, it’s best to keep this Mac and Cheese Meatloaf Casserole far from their reach, as ingredients like onion and certain cheeses can be harmful to them.

For a gluten-free variation, simply replace the breadcrumbs and macaroni with suitable substitutes.
How can I prevent my meatloaf from being dry?
Very good question! To avoid a dry meatloaf, make sure to use high-quality ground meat with some fat, as low-fat options can lead to dryness.
