Ingredients for Mac and Cheese Meatloaf Casserole

- 1 lb ground beef, tender and juicy
- 1/2 cup diced onion, fragrant and savory
- 1/2 cup breadcrumbs, for that perfect binding
- 1 large egg, to hold everything together
- 2 cups macaroni, uncooked and ready to boil
- 2 cups shredded cheddar cheese, gooey and melty
- 4 cups milk (divided), for creaminess
- 2 tbsp butter, rich and smooth
- Various seasonings: salt, pepper, paprika, and dry mustard, to elevate the flavors
Step-by-Step Directions
- Preheat your oven to 350°F (175°C). This ensures that your casserole cooks evenly and thoroughly.
- In a mixing bowl, combine the ground beef, diced onion, breadcrumbs, egg, and 2 cups of milk. Season generously with salt, pepper, and a pinch of paprika. Mix well until all ingredients are thoroughly incorporated. This mixture should smell fragrant and full of potential.
- Press the seasoned meat mixture into a greased 9×13-inch baking dish, ensuring an even layer that will form the base of your casserole.
- Bake the meatloaf in the preheated oven for 20 minutes, letting it start to set and brown on the edges.
- Meanwhile, cook your macaroni according to package instructions. Once al dente, drain and set aside.
- In a separate saucepan, melt the butter over medium heat. Stir in a bit of flour to create a roux, and gradually whisk in 2 cups of the remaining milk until thickened, creating a luscious cheese sauce.
- Add the seasonings and 1½ cups of shredded cheddar cheese to the sauce, stirring until everything is melted and beautifully creamy.
- Gently mix the cooked macaroni into the cheese sauce, ensuring that every piece is coated in that cheesy goodness.
- Pour the prepared macaroni and cheese mixture over the baked meatloaf in the baking dish. Sprinkle the remaining cheese on top, letting it bubble and brown together in the oven.
- Return the casserole to the oven and bake for an additional 25 minutes. By this time, your kitchen will smell divine, and the dish will be bubbling with cheesy perfection!
Tips & Tricks
To make your Mac and Cheese Meatloaf Casserole even more special, consider these chef’s secrets:

- If you want to save time, prepare the meatloaf mixture the night before and assemble the casserole the next evening.
Serving Suggestions & Pairings
This casserole is a showstopper on its own, but pairing it with a side salad or some steamed vegetables can create a well-rounded meal. For a fun presentation, serve it with a dollop of sour cream or a sprinkle of fresh herbs like parsley or cilantro for an eye-catching final touch. A side of garlic bread would add a cozy feel and make for the perfect family dinner setting.
