1 teaspoon dried parsley

For the Homemade Mac and Cheese

Kitchen Equipment

Before you begin, gather the following kitchen tools:

Large mixing bowl
Large pot
Medium saucepan
Whisk
Wooden spoon
9×13-inch baking dish
Measuring cups and spoons
Aluminum foil
Cheese grater

Step-by-Step Instructions

Step 1: Prepare the Oven

Preheat your oven to 375°F (190°C). Lightly grease your baking dish with cooking spray or butter to prevent sticking.

Step 2: Make the Meatloaf

In a large bowl, combine the ground beef, breadcrumbs, eggs, diced onion, minced garlic, milk, ketchup, Worcestershire sauce, salt, pepper, paprika, parsley, and onion powder.

Mix everything together gently using your hands or a spoon until just combined. Avoid overmixing, as this can make the meatloaf dense instead of tender.

Transfer the mixture into your prepared baking dish and press it into an even layer.

Bake for 30 minutes.

Step 3: Cook the Pasta

While the meatloaf bakes, bring a large pot of salted water to a boil.

Cook the elbow macaroni until just al dente according to the package instructions. Since the pasta will continue cooking in the oven, avoid overcooking it.

Drain the pasta and set it aside.

Step 4: Prepare the Cheese Sauce

In a medium saucepan, melt the butter over medium heat.

Whisk in the flour and cook for about one minute until smooth.

Gradually pour in the milk while whisking constantly to avoid lumps.

Continue cooking until the sauce thickens.

Add the cheddar cheese, mozzarella cheese, garlic powder, mustard powder, salt, and pepper.

Stir continuously until the cheese melts completely into a rich and creamy sauce.

Step 5: Mix the Macaroni

Add the cooked macaroni to the cheese sauce.

Stir gently until every piece of pasta is coated in the creamy cheese mixture.

Step 6: Assemble the Casserole

Remove the meatloaf from the oven.

Spread the macaroni and cheese evenly across the meatloaf.

Sprinkle the remaining cheddar cheese generously over the top.

Return the casserole to the oven and bake for another 15 to 20 minutes, or until the cheese is melted, bubbly, and lightly golden.

Step 7: Rest Before Serving

Allow the casserole to rest for 10 minutes before cutting into portions.

This helps the layers hold together and makes serving much easier.

Garnish with freshly chopped parsley before serving if desired.

Expert Tips for the Best Results

For the creamiest mac and cheese, always shred cheese from a block instead of using pre-shredded cheese. Freshly grated cheese melts more smoothly because it doesn’t contain anti-caking agents.

Using ground beef with an 80/20 fat ratio creates a juicy meatloaf without becoming greasy.

Don’t skip the resting time after baking. Allowing the casserole to cool slightly helps it slice neatly while keeping all the flavors together.

If you enjoy extra flavor, mix a little smoked paprika or cayenne pepper into the cheese sauce.

Delicious Variations

One of the best things about this casserole is how easy it is to customize.

Try adding crispy bacon pieces between the meatloaf and macaroni layers for a smoky flavor.

Swap cheddar for Monterey Jack, Gouda, Colby, or Pepper Jack cheese.

Add sautéed mushrooms, spinach, roasted peppers, or caramelized onions.

Use ground turkey or chicken for a lighter version.

Top with seasoned breadcrumbs before baking for an extra crispy finish.

What to Serve with Mac and Cheese Meatloaf Casserole

Although this casserole is filling on its own, it pairs wonderfully with simple side dishes.

Some great serving ideas include:

Fresh green salad
Garlic bread
Roasted broccoli
Steamed green beans
Honey glazed carrots
Caesar salad
Roasted asparagus
Corn on the cob

These sides balance the richness of the casserole while creating a complete family meal.

Storage Instructions

Allow leftovers to cool completely before storing.

Place portions in airtight containers and refrigerate for up to 4 days.

For longer storage, wrap tightly and freeze for up to 3 months.

To reheat, microwave individual servings for 2–3 minutes or bake at 350°F (175°C) until hot throughout.

Frequently Asked Questions

Can I prepare this casserole ahead of time?

Yes. Assemble the entire casserole, cover it tightly, and refrigerate for up to 24 hours before baking. Add a few extra minutes to the baking time if baking directly from the refrigerator.

Can I freeze Mac and Cheese Meatloaf Casserole?

Absolutely. Freeze it either before or after baking. Wrap it well to prevent freezer burn and thaw overnight in the refrigerator before reheating.

What is the best cheese for mac and cheese?

Sharp cheddar is the most popular choice because of its bold flavor, but combining it with mozzarella, Monterey Jack, Gouda, or Colby creates an even creamier texture.

How do I keep my meatloaf from falling apart?

Eggs and breadcrumbs act as binders, helping the meatloaf hold its shape. Mixing gently and allowing the casserole to rest after baking also improves the texture.

Can I make this recipe gluten-free?

Yes. Simply use gluten-free breadcrumbs, gluten-free pasta, and a gluten-free flour blend for the cheese sauce.
