Whether you’re feeding a hungry family or prepping a casserole to share, this one is guaranteed to become a regular in your dinner rotation.

Ingredients Overview

This casserole is made with familiar pantry staples, but the magic lies in how they’re combined.

Ground Beef

Lean ground beef (80/20 or 85/15) forms the base of the meatloaf layer. It provides rich flavor and hearty texture. For a leaner option, you can use ground turkey or chicken, but expect a slightly lighter taste.

Breadcrumbs and Eggs

These act as binding agents in the meatloaf. Italian-seasoned breadcrumbs add a subtle herb flavor, while the eggs help hold everything together. Panko can also be used for a crumblier texture.

Onion and Garlic

Finely chopped onion adds moisture and sweetness to the meatloaf. Fresh garlic brings depth—don’t skip it unless you’re sensitive to its bold flavor.

Worcestershire Sauce and Ketchup

Classic meatloaf ingredients that balance savory and sweet. Worcestershire adds umami richness, while ketchup brings a mild tang. You can substitute BBQ sauce for a smokier flavor profile.

Macaroni

Elbow macaroni is traditional, but any short pasta (like shells or cavatappi) works. Cook just until al dente so it holds its shape during baking.

Cheddar Cheese

Sharp cheddar is ideal for its strong flavor and meltability. A blend of cheddar and mozzarella can give you both stretch and depth. Avoid pre-shredded cheese if possible—it doesn’t melt as smoothly.

Milk and Butter

These create the base of the cheese sauce. Whole milk is best for creaminess, but 2% works in a pinch. Use real butter for richer flavor.

Flour

Used to make a roux for the cheese sauce. All-purpose flour works best.

Topping Options

For extra crunch, top with crushed Ritz crackers, toasted panko, or even French-fried onions. A light sprinkle of paprika or parsley adds visual contrast and flavor.

Step-by-Step Instructions

This casserole is made in layers: first the meatloaf, then the mac and cheese, then baked to golden perfection.

1. Prepare the Meatloaf Layer

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish.

In a large mixing bowl, combine:

• 1 ½ pounds ground beef

• 1 cup Italian breadcrumbs

• 2 eggs

• ½ cup finely chopped onion

• 2 garlic cloves, minced

• 2 tablespoons Worcestershire sauce

• ¼ cup ketchup

• 1 teaspoon salt

• ½ teaspoon black pepper

Mix gently with your hands or a fork—overmixing can lead to a dense meatloaf.

Press the meat mixture evenly into the bottom of the prepared baking dish to form a flat, compact layer. Bake uncovered for 20–25 minutes, until lightly browned and set.

2. Cook the Macaroni

While the meatloaf bakes, boil a pot of salted water and cook 2 cups of elbow macaroni until al dente. Drain and set aside.

3. Make the Cheese Sauce

In a medium saucepan over medium heat:

• Melt 4 tablespoons of butter

• Whisk in ¼ cup flour to form a roux

• Cook for 1 minute, whisking constantly

Slowly whisk in 2 cups of warm milk. Let the mixture thicken (3–5 minutes), then add:

• 3 cups shredded sharp cheddar cheese

• ½ teaspoon salt

• ¼ teaspoon black pepper

• ½ teaspoon dry mustard (optional, for a tangy note)

Stir until cheese is melted and sauce is smooth. Combine with the cooked pasta.

4. Assemble the Casserole

Once the meatloaf base is done, carefully drain off any excess fat.

Spread the mac and cheese evenly over the meatloaf layer.

Optional: Top with ½ cup shredded cheddar or a crunchy topping like crushed crackers or panko.

5. Bake Until Bubbling

Return the dish to the oven and bake for another 20 minutes at 375°F, until the top is golden and bubbly.

Let rest for 5–10 minutes before slicing. This helps everything hold together when served.

Tips, Variations & Substitutions

Cooking Tips

• Don’t overbake the meatloaf layer—it finishes cooking with the pasta.

• Let the casserole sit before slicing for cleaner portions.

• Use freshly shredded cheese for the smoothest sauce.

Flavor Variations

• BBQ Twist: Swap ketchup with BBQ sauce in the meatloaf.

• Southwestern Style: Add diced green chiles and taco seasoning to the beef, and use pepper jack cheese in the macaroni.

• Bacon-Topped: Crumble cooked bacon over the top before baking.

Dietary Substitutions

• Gluten-Free: Use GF pasta, gluten-free breadcrumbs, and a 1:1 GF flour for the roux.

• Dairy-Free: Use plant-based butter, unsweetened oat or almond milk, and dairy-free shredded cheese.

• Low-Carb: Replace pasta with cauliflower florets and use almond flour instead of breadcrumbs.

Serving Ideas & Occasions

This casserole is filling enough to stand alone, but pairs beautifully with:

• Steamed green beans or broccoli

• A crisp garden salad with tangy vinaigrette

• Garlic bread or buttery dinner rolls

It’s a wonderful choice for:

• Cozy weeknight dinners

• Potlucks or family gatherings

• Game-day spreads or weekend meal prep

The flavor combination is nostalgic and comforting—perfect for feeding both picky eaters and comfort food lovers alike.

Nutritional & Health Notes

Mac and Cheese Meatloaf Casserole is a hearty, indulgent meal that packs protein, carbs, and dairy all in one.

• Protein: Ground beef and cheese offer over 20g of protein per serving.

• Carbs: Pasta and breadcrumbs contribute most of the carbs. Use whole wheat pasta or a veggie-based version for added fiber.

• Fats: Rich in saturated fat from cheese and beef. Lighten it up with leaner meats or reduced-fat cheese.

• Portion Tips: Serve with a side of greens to balance the richness, or portion into meal prep containers with roasted vegetables.

While not a diet dish, it’s satisfying in moderation and perfect for when you crave a home-cooked classic.

FAQs

Q1: Can I make Mac and Cheese Meatloaf Casserole ahead of time?

A1: Yes, you can assemble the casserole up to a day in advance. Store it covered in the refrigerator and bake just before serving. If baking from cold, add 10–15 minutes to the cook time.

Q2: Can I freeze this casserole?

A2: Absolutely. Bake the meatloaf layer, cool completely, then add the mac and cheese. Wrap tightly in foil and freeze for up to 2 months. Thaw overnight in the fridge and bake as directed.

Q3: What’s the best cheese for mac and cheese in this recipe?

A3: Sharp cheddar is the classic choice for bold flavor and smooth melting. For extra creaminess, you can mix in Monterey Jack, Colby, or mozzarella.

Q4: Can I make this with leftover meatloaf?

A4: Yes. Crumble or slice leftover meatloaf and layer it in the bottom of your dish. Then prepare the mac and cheese and bake as usual.

Q5: Is there a vegetarian version?

A5: You can replace the meatloaf with a lentil or chickpea loaf and use plant-based cheese and milk. It won’t have the same flavor, but it’s a hearty and satisfying meat-free option.

Q6: Can I use boxed mac and cheese?

A6: If you’re short on time, boxed mac and cheese works, but the homemade version has a richer, creamier taste. Use 2–3 prepared boxes for a full casserole.

Q7: How do I reheat leftovers?

A7: Reheat single portions in the microwave or warm the whole dish in a 350°F oven, covered, for 20–25 minutes. Add a splash of milk if the mac and cheese seems dry.
