Step-by-Step Instructions on How to Make Mac and Cheese Meatloaf Casserole

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). Lightly grease your baking dish and set aside.

Step 2: Prepare the Meatloaf Base

In a large mixing bowl, combine ground beef, bread crumbs, eggs, milk, garlic powder, onion powder, salt, pepper, and 1 cup shredded cheese. Mix just until combined — don’t overmix or the meatloaf will be tough.

Press the mixture evenly into the prepared baking dish to form your meatloaf layer.

Step 3: Bake the Meatloaf Layer

Bake for 20–25 minutes, or until mostly cooked through. You’ll add the mac and cheese layer next, so it doesn’t need to be fully done at this stage.

Step 4: Make the Mac and Cheese

While the meatloaf bakes, melt butter in a medium saucepan over medium heat. Whisk in the flour and cook for 1 minute. Slowly pour in milk, whisking constantly, until the sauce thickens (about 3–4 minutes).

Stir in 1 ½ cups shredded cheese, mustard powder, salt, and pepper. Stir until melted and smooth.

Add the cooked macaroni noodles and mix until fully coated.

Step 5: Assemble the Casserole

Remove the meatloaf from the oven and spread the mac and cheese mixture evenly on top. Sprinkle the remaining ½ cup of cheddar cheese over the top for that gooey, golden finish.

Step 6: Bake and Finish

Return the casserole to the oven and bake for another 15–20 minutes, or until the top is bubbly and golden brown.

Step 7: Cool and Serve

Let the casserole cool for about 10 minutes before slicing. This helps it set up and makes serving easier.

The smell when this comes out of the oven is incredible — cheesy, savory, and comforting all at once! You’ll be tempted to dig in right away (I always do — and I’m kicking myself for not taking more photos before devouring it!).

What to Serve with Mac and Cheese Meatloaf Casserole

• Steamed green beans or broccoli for a lighter side.
• Simple salad with ranch or balsamic dressing.

• Roasted carrots or corn on the cob for a full, homey meal.

Storage Instructions

• Refrigerator: Store leftovers in an airtight container for up to 4 days.
• Freezer: Wrap tightly in foil or freezer-safe wrap and freeze for up to 2 months.
