Ultimate Mac and Cheese Meatloaf Casserole


 

1. Prep the Meatloaf Mixture

  • In a bowl, mix ground beef, breadcrumbs, onion, egg, ketchup, Worcestershire sauce, and seasonings until combined.

  • Press evenly into the bottom of a greased 9x13-inch baking dish.

2. Cook the Macaroni

  • Boil macaroni 2 minutes less than package instructions (it’ll finish cooking in the oven). Drain and set aside.

3. Make the Cheese Sauce

  • Melt butter in a saucepan, whisk in flour to make a roux.

  • Slowly add milk, whisking until smooth. Cook until slightly thickened.

  • Remove from heat, stir in cheddar, mozzarella, Parmesan, and seasonings until melted.

  • Toss with cooked macaroni.

4. Assemble & Bake

  • Spread mac & cheese over the meatloaf layer.

  • Top with extra cheese and fried onions (if using).

  • Bake at 375°F (190°C) for 30-35 mins until bubbly and golden.

  • Let rest 5-10 mins before serving.


Pro Tips for the Best Casserole

🔹 Pre-cook the meatloaf 10 mins alone for extra browning (optional).
🔹 Use a mix of cheeses for maximum flavor (Gruyère works great too!).
🔹 Make ahead – Assemble, refrigerate, and bake when ready.
🔹 Crispy topping hack – Broil for 2-3 mins at the end.


3 Delicious Variations

  1. BBQ Style – Swap ketchup for BBQ sauce in the meatloaf.

  2. Bacon Lovers – Add crumbled bacon between layers.

  3. Spicy Kick – Mix in diced jalapeños or hot sauce.


Why This Dish is a Game-Changer

This casserole solves the "What’s for dinner?" debate by combining two all-time favorites. The meatloaf stays juicy, the mac & cheese is ultra-creamy, and the cheesy topping adds crunch. It’s comfort food perfection with minimal cleanup!
