Mac and Cheese Meatloaf Casserole Ingredients
For the Meatloaf Base
• Ground Beef – Provides a hearty base for flavor and protein; choose lean (85/15 or 80/20) to minimize grease.
• Breadcrumbs – Binds the meatloaf mixture while adding texture; use store-bought or homemade; panko can lighten it.
• Egg – Acts as a binder, essential for keeping the meatloaf intact when sliced.
• Milk – Adds moisture to prevent the meatloaf from becoming dry; any fat percentage works.
• Onion – Introduces aromatic flavor and moisture; ensure a fine chop for even distribution.
• Garlic Powder – Infuses savory flavor evenly without adding texture; ideal over fresh garlic.
• Barbecue Sauce – Creates a tangy glaze on the meatloaf that caramelizes during baking, enhancing flavor.
For the Mac and Cheese Layer
• Elbow Macaroni – Classic pasta choice for mac and cheese; alternatives include other short pasta shapes.
• Butter – Essential for creating a roux, forming a base for a smooth cheese sauce.
• Flour – Works with butter to form a roux, thickening the milk for a rich cheese sauce.
• Milk – Adds creaminess; use any fat percentage based on personal preference.
• Cheddar Cheese – Brings sharp, rich flavor to the mac and cheese; feel free to mix with other cheeses for a different taste.
• Paprika – Adds subtle warmth and color; optional based on pantry availability.
This Mac and Cheese Meatloaf Casserole is destined to become a family favorite!
Step‑by‑Step Instructions for Mac and Cheese Meatloaf Casserole
Step 1: Preheat and Prepare Your Dish
Begin by preheating your oven to 350°F (175°C). While it heats, grease a 9×13 inch baking dish with cooking spray or a touch of butter to prevent sticking. This simple preparation step ensures that your Mac and Cheese Meatloaf Casserole will come out perfectly every time, making clean-up a breeze!
Step 2: Make the Meatloaf Mixture
In a large mixing bowl, combine the ground beef, breadcrumbs, egg, milk, finely chopped onion, garlic powder, and barbecue sauce. Use your hands or a spoon to mix until all ingredients are well incorporated, forming a cohesive mixture. Spread this flavorful meat mixture evenly into the bottom of your greased baking dish, creating a solid base for the casserole.
Step 3: Cook the Elbow Macaroni
Bring a pot of salted water to a boil and cook the elbow macaroni until just al dente, about 6-8 minutes, depending on package instructions. Once cooked, drain and set aside. This ensures your macaroni will maintain a slight firmness when baked with the casserole, providing the perfect texture.
Step 4: Prepare the Cheese Sauce
In a medium saucepan over medium heat, melt two tablespoons of butter. Add an equal amount of flour, stirring continuously for about 2 minutes to form a roux. Gradually whisk in 2 cups of milk, cooking until thickened, around 4-5 minutes. Once thickened, remove from heat and stir in the shredded cheddar cheese until melted and smooth, creating a delicious cheese sauce for the macaroni.
Step 5: Combine Mac and Cheese
Gently fold the drained elbow macaroni into the cheese sauce until evenly coated. The creamy texture from the cheese sauce will envelop the pasta beautifully, completing the mac and cheese layer for your casserole. This step brings the rich flavor that pairs so wonderfully with the savory meatloaf below!
Step 6: Assemble the Casserole
Spoon the mac and cheese mixture over the meatloaf layer in the baking dish, spreading it out gently with a spatula to cover the meatloaf completely. This creates a delightful two-layer effect in your Mac and Cheese Meatloaf Casserole, ensuring each bite is packed with flavor.
Step 7: Bake to Perfection
Cover the baking dish with aluminum foil and bake in the preheated oven for 30 minutes. After that, uncover the dish and bake for an additional 15 minutes, until the top is bubbling and golden brown. This final bake gives the casserole a comforting, inviting appearance—it’s hard to resist!
Step 8: Serve and Enjoy
Once out of the oven, let the casserole cool for a few minutes before slicing into squares to serve. This resting period helps the layers set together while the aromas fill your kitchen. Your comforting Mac and Cheese Meatloaf Casserole is now ready to be served—perfect for sharing with family and friends!
