Ingredients + Tips

Main Ingredients (Scale: 1x)

• 1 lb ground beef
  Use 80/20 ground beef for the best balance of flavor and moisture. Leaner beef works but may result in a slightly drier meatloaf.

• 2 cups uncooked macaroni
  Classic elbow macaroni is ideal, but small shells or cavatappi also work well.

• 2 cups shredded cheddar cheese
  Sharp cheddar adds bold flavor, while mild cheddar creates a creamier profile. Shred your own for best melting results.

• 1/2 cup diced onion
  Finely dice the onion so it blends smoothly into the meatloaf.

• 1/2 cup breadcrumbs
  Breadcrumbs help bind the meatloaf and keep it tender. Panko or traditional breadcrumbs both work.

• 1 large egg
  Essential for structure and moisture in the meatloaf.

• 1/4 cup milk (for meatloaf)
  Softens the breadcrumbs and keeps the meatloaf juicy.

• 2 tbsp butter (for cheese sauce)
  Forms the base of the roux for a smooth sauce.

• 2 cups milk (for cheese sauce)
  Whole milk creates the creamiest texture, but 2% works as well.

• 2 tbsp flour
  Thickens the cheese sauce.

• 1 tsp salt
  Enhances all the flavors in both layers.

• 1/2 tsp black pepper
  Adds gentle warmth.

• 1/2 tsp paprika
  Provides subtle smokiness and color.

• 1/2 tsp dry mustard
  Boosts the cheesy flavor without overpowering the dish.

Ingredient Tips

• Avoid pre-shredded cheese when possible; it contains anti-caking agents that prevent smooth melting.

• Slightly undercook the macaroni so it doesn’t become mushy during baking.

• Season every layer lightly to ensure balanced flavor throughout the casserole.

Step-by-Step Instructions

1. Prepare the Oven and Baking Dish

Preheat your oven to 350°F (175°C). Lightly grease a baking dish to prevent sticking and ensure easy serving.

2. Make the Meatloaf Base

In a large bowl, combine ground beef, diced onion, breadcrumbs, egg, 1/4 cup milk, salt, and black pepper. Mix gently until just combined—overmixing can make the meatloaf dense.

3. Form the Meatloaf Layer

Press the meat mixture evenly into the prepared baking dish, smoothing the surface so it cooks uniformly.

4. Partially Bake the Meatloaf

Bake the meatloaf for 20 minutes. This step helps set the base before adding the macaroni layer.

5. Cook the Macaroni

While the meatloaf bakes, cook the macaroni according to package instructions. Drain well and set aside.

6. Make the Cheese Sauce

In a saucepan over medium heat, melt the butter. Stir in the flour and cook for about 1 minute to eliminate the raw flour taste.

7. Add the Milk

Gradually whisk in the milk, stirring constantly until the sauce thickens and becomes smooth.

8. Season the Sauce

Add paprika and dry mustard, stirring well to distribute the seasoning.

9. Melt the Cheese

Remove the saucepan from heat and stir in the shredded cheddar cheese until fully melted and silky.

10. Combine Macaroni and Cheese Sauce

Add the cooked macaroni to the cheese sauce and stir until evenly coated.

11. Assemble the Casserole

Spread the mac and cheese evenly over the partially baked meatloaf layer.

12. Final Bake

Return the dish to the oven and bake for 25 minutes, or until bubbly and lightly golden on top.

13. Rest and Serve

Allow the casserole to rest for 5–10 minutes before slicing. This helps it hold together when serving.

Tips for Best Results

• Don’t overmix the meatloaf: Gentle mixing keeps it tender.

• Customize the cheese: Cheddar, mozzarella, Monterey Jack, or Colby all work beautifully.

• Add vegetables: Finely chopped bell peppers, peas, or corn add color and nutrition.

• Create a crispy top: Sprinkle extra cheese or breadcrumbs before the final bake.

• Let it rest: A short resting time improves texture and presentation.
