- 2 tablespoons all-purpose flour

How to Make Mac and Cheese Meatloaf Casserole (Step-by-Step)
Step 1: Prepare the Oven and Pan
Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
Step 2: Make the Meatloaf Layer
In a large mixing bowl, combine ground beef, breadcrumbs, egg, onion, garlic powder, salt, pepper, paprika, and ketchup. Mix until just combined—don’t overwork it. Press the mixture evenly into the bottom of the baking dish.
Step 3: Bake the Meatloaf Base
Bake the meatloaf layer for 20–25 minutes, until the edges start to brown and the internal temperature reaches at least 160°F (71°C).
Step 4: Cook the Macaroni
While the meatloaf bakes, cook macaroni in salted water until al dente. Drain and set aside.
Step 5: Make the Cheese Sauce
In a saucepan over medium heat, melt the butter. Stir in flour and cook for 1 minute, whisking constantly. Gradually add milk, whisking to avoid lumps. Simmer until thickened, about 4–5 minutes.
Remove from heat and stir in shredded cheddar cheese, salt, and mustard powder. Mix until cheese is melted and smooth.
Step 6: Combine Mac and Cheese
Add the cooked macaroni to the cheese sauce and stir to coat evenly.
Step 7: Assemble the Casserole
Spread the mac and cheese mixture evenly over the baked meatloaf. Sprinkle with Parmesan if using.
Step 8: Final Bake
Return the casserole to the oven and bake for another 15–20 minutes, or until bubbly and golden on top.
Step 9: Cool Slightly and Serve
Let the casserole sit for 5–10 minutes before slicing and serving.
Flavor Tips for the Best Meat Casserole
- Use ground beef with some fat – It keeps the meatloaf juicy.
- Grate your own cheese – Pre-shredded cheeses often contain anti-caking agents that affect melting.
- Don’t skip the mustard powder – It enhances the sharpness of the cheese.
- Balance seasoning – Taste the cheese sauce before adding to adjust salt if needed.
- Bake uncovered – To get that golden, crispy top layer.
Kitchen Tools You’ll Need

- Large mixing bowl
- Medium saucepan
- Whisk
- Large spoon or spatula
- Cheese grater
- Measuring cups and spoons
- Oven mitts
Everything needed is common in most home kitchens—no fancy tools required!
Serving Ideas for Meatloaf Casserole with Mac and Cheese

- Garlic bread or cornbread muffins
- Fresh fruit or applesauce (especially for kids)
This casserole also makes a great next-day lunch—just reheat and go.
How to Store, Freeze & Reheat Leftovers
To Store:

To Freeze:

To Reheat:
- Microwave: Heat individual portions for 2–3 minutes
- Oven: Cover and reheat at 350°F for 15–20 minutes
- Avoid drying out: Add a splash of milk to keep the mac and cheese creamy when reheating
Common Mistakes to Avoid in Mac and Cheese Casseroles
- Overcooking the pasta – It continues cooking in the oven
- Underseasoning the meat – Taste test a small cooked portion if unsure
- Not draining meat fat – After baking the meatloaf layer, drain excess fat to avoid greasy results
- Using pre-shredded cheese – It won’t melt as well or taste as fresh
- Assembling too early – Mac and cheese can dry out if it sits too long before baking

- Swap proteins: Use ground turkey, chicken, or a plant-based alternative
