Mac and Cheese Meatloaf Casserole Ingredients
For the Meatloaf
• Ground Beef – Primary protein for robust flavor and structure; consider swapping with ground turkey for a leaner option.
• Onion – Adds a punch of flavor; if you prefer something milder, use shallots instead.
• Breadcrumbs – Helps to bind the meatloaf together; gluten-free breadcrumbs can work well for a gluten-free dish.
• Egg – Acts as a binder; use a chia or flax egg for a vegan alternative.
• Milk – Keeps the meatloaf moist; opt for plant-based milk to make it dairy-free.
• Salt – Essential for enhancing flavor; remember to adjust to your taste.
• Pepper – Adds a touch of seasoning; garlic powder is a great option for those looking for extra flavor.
For the Pasta and Cheese Sauce
• Pasta (Macaroni) – The foundational base of the creamy cheese mixture; try whole wheat or gluten-free pasta for healthier options.
• Butter – Used in the cheese sauce for richness; replace with olive oil for a lighter twist.
• Flour – Helps thicken the cheese sauce; cornstarch can serve as a gluten-free thickener.
• Cheese (shredded) – Brings creaminess and flavor; mix cheeses like mozzarella and gouda for an exciting blend.
• Paprika – Adds depth to the flavor profile; cayenne can be used for those who prefer a spicier kick.
• Dry Mustard – Enhances the cheese flavor; it’s optional but a nice touch for those who enjoy a punch of zest.
Gather these ingredients, and you’ll be well on your way to creating the unforgettable Mac and Cheese Meatloaf Casserole!
Step‑by‑Step Instructions for Mac and Cheese Meatloaf Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This temperature is crucial for baking the Mac and Cheese Meatloaf Casserole evenly. While the oven heats up, you can gather your ingredients and prepare your baking dish by greasing it lightly to ensure an easy release after baking.
Step 2: Prepare the Meatloaf Mixture
In a large mixing bowl, combine ground beef, finely chopped onion, breadcrumbs, egg, milk, salt, and pepper. Use your hands or a wooden spoon to mix the ingredients until they are fully combined, ensuring that you don’t overwork the mixture. Once blended, press the meat mixture into the greased baking dish, forming an even layer at the bottom.
Step 3: Bake the Meatloaf
Place the meatloaf in the preheated oven and bake for approximately 20 minutes. During this time, the meatloaf will start to firm up and develop a nice golden brown hue on the top. Keep an eye on it; you want it to be just cooked through, as the following steps will introduce more moisture with the macaroni.
Step 4: Cook the Macaroni
While the meatloaf is baking, cook the macaroni according to the package directions until al dente. This typically takes about 7-9 minutes. Once cooked, drain the pasta and set it aside, allowing it to steam off while you prepare the cheese sauce. The pasta will absorb some of the sauce’s creaminess for that delightful texture you crave in the casserole.
Step 5: Make the Cheese Sauce
In a medium saucepan over medium heat, melt 2 tablespoons of butter. Once melted, whisk in 2 tablespoons of flour and cook for about a minute to create a roux. Gradually whisk in 2 cups of milk, continuing to stir until the mixture thickens, about 3–5 minutes. Add salt, pepper, paprika, and dry mustard, stirring until fully incorporated, then mix in the shredded cheese until melted and creamy.
Step 6: Combine Macaroni and Cheese Sauce
Add the cooked macaroni to the cheese sauce, stirring gently to ensure every piece is coated. This creamy mix is the heart of the Mac and Cheese Meatloaf Casserole. Once combined, pour this delightful mixture over the partially baked meatloaf, spreading it evenly. For an extra cheesy topping, sprinkle additional shredded cheese on top of the macaroni.
Step 7: Bake the Casserole
Return the dish to the oven and bake for an additional 25 minutes. The cheese should melt and become bubbly, while the top turns a lovely golden brown—this is what you want for the perfect Mac and Cheese Meatloaf Casserole. Keep an eye on it towards the end to avoid over-browning.
Step 8: Let It Rest
After baking, remove the casserole from the oven and let it sit for about 10 minutes. This resting time will allow the casserole to set, making it easier to cut and serve. The smells in your kitchen will be incredible, as you can prepare to serve up comforting slices of this delicious dish!

Expert Tips for Mac and Cheese Meatloaf Casserole
-
Quality Matters: Choose high-quality ground beef to ensure moisture and flavor. Avoid lean options that may dry out during baking.
-
Macaroni Precision: Cook macaroni al dente, as it will continue to cook in the oven. This prevents a mushy texture in your casserole.

Season Generously: Don’t skimp on seasoning both the meatloaf and cheese sauce. A well-seasoned dish enhances the overall flavor profile.
