How to Make Mac and Cheese Meatloaf Casserole
-
Preheat your oven to 350°F (175°C). This is essential for evenly cooking your casserole, ensuring a perfectly baked top and a cozy meal.
-
Combine the ground beef, onion, breadcrumbs, egg, milk, salt, and pepper in a bowl. Mix thoroughly until everything is well incorporated, creating a flavorful base for your meatloaf.
-
Press the meat mixture into a greased baking dish and bake for 20 minutes. This helps to create a solid foundation for your casserole that holds all the delicious layers together.
-
Cook the macaroni until al dente, then drain. The pasta will continue to cook in the oven, so slightly undercooking it is key to maintaining the perfect texture.
-
Melt the butter in a saucepan, then stir in the flour and cook for about 1 minute. This forms a roux that thickens your cheese sauce beautifully.
-
Whisk in the milk gradually, cooking until thickened; then stir in the seasoning and cheese until melted. This creamy cheese sauce is the heart of the dish, bringing that comforting flavor!
-
Mix the cooked macaroni into the cheese sauce and layer it on top of the meatloaf. This creates a delightful combination of flavors and textures that everyone will love.
-
Top with remaining cheese and bake for an additional 25 minutes until bubbly. You want that beautiful golden brown finish to signal it’s ready to take out of the oven!

Mac and Cheese Meatloaf Casserole Recipe FAQs
How do I choose the right ground meat for this casserole?
Absolutely! For the best flavor, I recommend using high-quality ground beef. Look for a blend that’s 80/20 (meat to fat) for optimal juiciness. If you’re looking for a leaner option, ground turkey works well too, though you may want to add some extra seasoning for depth.
What’s the best way to store leftovers?
Easy peasy! Store any leftovers in an airtight container in the refrigerator for up to 3 days. Make sure it’s completely cooled before sealing to avoid moisture build-up, which can make your casserole soggy.
Can I freeze the Mac and Cheese Meatloaf Casserole?
Certainly! To freeze, wrap the casserole tightly in plastic wrap, then in aluminum foil to prevent freezer burn. It can be stored in the freezer for up to 2 months. When you’re ready to enjoy it again, just thaw in the fridge overnight, then reheat in the oven until heated through.
What should I do if the cheese sauce is too thick?
No worries! If your cheese sauce is thicker than you like, simply whisk in a little more milk, gradually, until you reach your preferred consistency. Always taste and adjust the seasoning as necessary—after all, you want every bite to be tasty!
Are there any dietary adjustments I can make?
Very much! For a gluten-free version, substitute regular breadcrumbs with gluten-free breadcrumbs and use cornstarch instead of flour for the cheese sauce. If you’re vegan, swap out the meat for lentils or a plant-based ground meat and use a flaxseed meal mixture instead of the egg. Your creativity can shine through in this savory dish!
How do I know when the casserole is done baking?
To ensure your casserole is perfectly cooked, check for bubbling edges and a golden top after the final bake of 25 minutes. A thermometer inserted into the center should read at least 160°F (70°C). Let it cool for a few minutes before serving to help with slicing!
