Mac and Cheese Meatloaf Casserole Ingredients
For the Meatloaf Base
- Ground Beef – A hearty source of protein; substitute with turkey or plant-based options for a lighter dish.
- Onion (1/2 cup, diced) – Adds essential flavor and moisture; shallots offer a subtler taste if preferred.
- Breadcrumbs (1/2 cup) – Binds the meatloaf together; crushed crackers or oats work well for varying textures.
- Egg (1 large) – Acts as a binder; a flax egg is a great vegan alternative.
- Milk (1/4 cup) – Moistens the meatloaf; use almond or oat milk for a dairy-free version.
- Salt (1.5 tsp total) – Enhances flavor; adjust according to taste, especially with salted ingredients.
- Pepper (3/4 tsp total) – Adds warmth and seasoning; white pepper can be used for a milder kick.
For the Mac and Cheese Layer
- Macaroni (2 cups, uncooked) – Forms the cheesy layer; gluten-free pasta is a fantastic substitute for dietary needs.
- Cheddar Cheese (2 cups, shredded) – Provides creaminess and flavor; try Monterey Jack for a different meltiness.
- Butter (2 tbsp) – Essential for creating the cheese sauce; margarine or a non-dairy spread can be used.
- Flour (2 tbsp) – Thickens the cheese sauce; consider cornstarch or a gluten-free flour mix as alternatives.
For Flavor Enhancements
- Paprika (1/2 tsp) – Adds color and an extra layer of flavor; smoked paprika can intensify the taste.
- Dry Mustard (1/2 tsp) – Boosts flavor in the cheese sauce; Dijon mustard can add a delightful tang.
This Mac and Cheese Meatloaf Casserole is not just a meal; it’s a heartwarming experience wrapped in comfort and nostalgia.
Step‑by‑Step Instructions for Mac and Cheese Meatloaf Casserole
Step 1: Preheat the Oven
Set your oven to 350°F (175°C) and let it warm up while you prepare the casserole. Preheating ensures that the Mac and Cheese Meatloaf Casserole cooks evenly, giving you that perfect cheesy, bubbly top and firm meatloaf base.
Step 2: Prepare the Meatloaf Base
In a large mixing bowl, combine 1 pound of ground beef, 1/2 cup of diced onion, 1/2 cup of breadcrumbs, 1 large egg, 1/4 cup of milk, 1.5 teaspoons of salt, and 3/4 teaspoon of pepper. Mix gently until just combined, avoiding overmixing, and then press the mixture into a greased 9×13-inch baking dish, forming an even layer.
Step 3: Bake the Meatloaf
Place the baking dish in the preheated oven and bake for 20 minutes. This initial bake allows the meatloaf to firm up slightly, creating a solid base for your Mac and Cheese Meatloaf Casserole. You’ll know it’s ready when it’s browned on the edges.
Step 4: Cook the Macaroni
While the meatloaf is baking, bring a large pot of salted water to a boil. Add 2 cups of uncooked macaroni and cook according to package directions until al dente; usually about 6-8 minutes. Once cooked, drain the macaroni in a colander and set it aside for later.
Step 5: Make the Cheese Sauce
In a medium saucepan over medium heat, melt 2 tablespoons of butter. Once melted, whisk in 2 tablespoons of flour and cook for about 1 minute to form a roux. Gradually pour in 2 cups of milk, stirring continuously until the sauce thickens, usually about 5 minutes. Then, mix in 1.5 cups of shredded cheddar cheese, 1/2 teaspoon of paprika, and 1/2 teaspoon of dry mustard until completely melted and creamy.
Step 6: Combine and Layer
Fold the cooked macaroni into the cheese sauce, ensuring each piece is well-coated. Carefully pour this cheesy macaroni mixture over the slightly baked meatloaf, spreading it evenly across the top. Finish by sprinkling the remaining 1/2 cup of cheese over the macaroni for an extra cheesy layer.
Step 7: Bake Again
Return the Mac and Cheese Meatloaf Casserole to the oven and bake for another 25 minutes. You’ll want to see the cheese melt and bubble, creating a delightful golden crust on top. Keep an eye on it to ensure it doesn’t over-brown.
Step 8: Serve and Enjoy
Once baked, remove the casserole from the oven and let it rest for about 5 minutes before serving. This slightly cooling period helps the layers settle, making it easier to cut and serve delectable slices of the Mac and Cheese Meatloaf Casserole.

Make Ahead Options
This Mac and Cheese Meatloaf Casserole is a fantastic option for busy home cooks looking to save time during hectic weeknights! You can prepare the meatloaf and cheese sauce components up to 24 hours in advance. Simply place the formed meatloaf in the baking dish and cover with plastic wrap, and refrigerate. The cheese sauce can be made ahead too; allow it to cool before storing in an airtight container. When you’re ready to enjoy, just cook the macaroni and assemble the casserole; pour the cheese sauce over the meatloaf, then bake everything together as instructed. This way, you’ll have a comforting dish that tastes just as delicious as if it were made fresh, all with minimal effort!
