Ingredient Notes
Ground beef is the classic choice for the meatloaf layer because it gives the casserole a rich, savory base. A meat mixture with a little fat usually works best because it keeps the meatloaf tender instead of dry.
Breadcrumbs, eggs, and milk help bind the meatloaf and keep it soft. Ketchup and Worcestershire sauce add flavor and moisture, while onion and garlic build that classic home-style meatloaf taste.
For the mac and cheese layer, elbow macaroni is the most traditional choice and works perfectly because it holds onto the sauce so well. Cheddar is the main cheese here because it gives that classic mac and cheese flavor, while mozzarella and Parmesan can add extra melt and depth if you want the casserole even richer.
The ketchup topping on the meatloaf adds sweetness, tang, and that classic glossy finish that makes the bottom layer taste even more like true meatloaf.
How to Make
1. Preheat the oven
Preheat your oven to 375°F and lightly grease a baking dish.
A 9×13-inch dish usually works well and gives enough room for both layers.
2. Make the meatloaf mixture
In a large mixing bowl, combine the ground beef, breadcrumbs, eggs, chopped onion, garlic, milk, ketchup, Worcestershire sauce, garlic powder, onion powder, salt, and black pepper.
Mix just until everything is combined. Try not to overmix, because that can make the meatloaf denser instead of tender.
3. Press the meatloaf into the dish
Spread the meat mixture evenly into the bottom of the prepared baking dish, pressing it down gently so it forms a solid layer.
Try to make the thickness even across the dish so it bakes consistently.
4. Add the meatloaf topping
In a small bowl, stir together the ketchup, brown sugar, and mustard.
Spread this mixture evenly over the meatloaf layer. This adds flavor and keeps the meatloaf from drying out too much while baking.
5. Bake the meatloaf layer first
Place the dish in the oven and bake for about 25 to 30 minutes.
This first bake helps the meatloaf set before the macaroni and cheese goes on top.
6. Cook the macaroni
While the meatloaf layer bakes, bring a pot of salted water to a boil and cook the elbow macaroni until just al dente.
Drain well and set aside. Be careful not to overcook it, since it will bake again later.
7. Make the cheese sauce
In a saucepan over medium heat, melt the butter. Whisk in the flour and cook for about 1 minute.
Slowly pour in the milk, whisking constantly so the sauce stays smooth. Let it cook until it thickens slightly.
Then stir in the cheddar cheese, and mozzarella or Parmesan if using. Add salt, black pepper, and paprika. Stir until the sauce is creamy and smooth.
8. Combine the macaroni and cheese sauce
Add the cooked macaroni to the cheese sauce and stir until all the pasta is evenly coated.
At this point, the mac and cheese should be creamy and rich, not dry. If needed, add a splash of milk to loosen it.
9. Add the mac and cheese layer
Once the meatloaf layer has baked, carefully remove the dish from the oven.
Spread the macaroni and cheese evenly over the top of the partially baked meatloaf layer.
10. Bake again
Return the casserole to the oven and bake for another 15 to 20 minutes, until the mac and cheese is hot and the casserole is fully cooked through.
If you want a more golden cheesy top, sprinkle extra cheddar over the top and broil briefly at the end.
11. Rest before serving
Let the casserole sit for about 10 minutes before slicing and serving.
This helps the layers settle and makes it easier to serve cleaner portions.
Tips for Best Results
Do not overmix the meatloaf layer. Mix only until combined so the meat stays tender and not too compact.
Bake the meatloaf layer before adding the mac and cheese. That step is important because it helps the base set properly and keeps the casserole from becoming too messy.
Cook the macaroni just until al dente. Since it bakes again later, slightly firmer pasta gives the best final texture.
Use freshly shredded cheese if possible. It usually melts more smoothly and gives a creamier mac and cheese layer.
Let the casserole rest before serving. Straight from the oven, the layers are softer and harder to slice neatly.
If the mac and cheese seems too thick before adding it to the casserole, stir in a little extra milk. A creamy top layer bakes better than a dry one.

What to Serve With It
This casserole is rich and filling, so lighter sides work especially well.
- Green salad
- Roasted broccoli
- Green beans
- Steamed vegetables
- Roasted carrots
- Dinner rolls
- Coleslaw
- Cucumber salad
A fresh or crisp vegetable side helps balance the heaviness of the casserole really nicely.
Storage and Reheating
- Refrigerator: Store in an airtight container for up to 4 days
- Freezer: Freeze for up to 2 months
- Reheating: Warm in the microwave or oven until heated through
- Best tip: Cover with foil in the oven so the top does not dry out too quickly
If reheating from the fridge, a small splash of milk over the mac and cheese layer can help keep it creamy.
Common Mistakes to Avoid
One common mistake is skipping the first bake for the meatloaf layer. If the base is not partially cooked first, the casserole can end up too loose.
Another is overcooking the macaroni before it goes into the cheese sauce. Since it bakes again, softer pasta can become mushy.
Using too little seasoning in the cheese sauce can also make the top layer taste flat, so be sure to season it well.
Finally, cutting the casserole too quickly after baking can make it harder to serve neatly. A short resting time helps a lot.
