Mac and Cheese Meatloaf Casserole layers savory beef with creamy mac and cheese for a crowd-pleasing, bake-and-slice comfort classic.
Imagine a tender meatloaf base—juicy, well-seasoned, and glazed—topped with a blanket of ultra-cheesy macaroni that turns golden at the edges. It’s weeknight-friendly comfort, designed for hungry families and potlucks alike.
You’ll mix a quick meatloaf (hello, buttery cracker crumbs and onion soup mix for big flavor), bake it partway, then crown it with stovetop mac and cheese and finish until bubbly. Slice into squares and watch it disappear.
What You Need to Make This Mac and Cheese Meatloaf Casserole
- Lean ground beef — Meaty foundation that bakes juicy and sturdy for slicing.
- Buttery round crackers — Crushed to stand in for breadcrumbs, adding richness and tender texture.
- Onion soup mix & eggs — Savory depth plus structure that binds the loaf.
- Ketchup & barbecue sauce — Whisked into a sweet-smoky glaze that caramelizes on top.
- Elbow macaroni — Classic shape that grabs sauce without drying out in the oven.
- Milk & condensed cheddar soup — Quick, creamy base that turns noodles silky.
- Salt, pepper, garlic and onion powders — Pantry seasonings for balanced flavor.
- Shredded mozzarella–cheddar blend — Melts stretchy and sharp for a gooey, golden finish.
Cooking Steps
- Heat the oven to 350°F. Grease a 9×13-inch dish. Stir ketchup and barbecue sauce together; set aside.
- Mix the meatloaf. Combine beef, finely crushed crackers, onion soup mix, eggs, and ½ cup of the glaze. Press evenly into the dish and spread remaining glaze over the top.
- Par-bake. Bake 30 minutes to set the loaf and develop flavor.
- Cook the pasta. Meanwhile, boil macaroni until just shy of al dente; drain.
- Make the mac. Whisk milk with condensed cheddar soup and seasonings. Toss with hot macaroni and half the shredded cheese.
- Layer and finish. Spoon the mac over the meatloaf, sprinkle remaining cheese, and bake 17–20 minutes until bubbling and lightly browned. Rest a few minutes before slicing.
Can I prep this ahead of time?
Yes. Assemble through Step 5, cover, and refrigerate up to 24 hours. Bake the meatloaf 5 extra minutes to account for the chill, then add the mac layer and finish as directed until hot and bubbly.
What crackers or binders can I swap?
Any buttery cracker works, or use plain breadcrumbs or crushed saltines. Keep the total volume similar so the loaf holds together. For a gluten-free option, choose GF crackers and verify the soup mix is GF.
How do I keep the mac and cheese creamy after baking?
Undercook pasta slightly and toss while it’s hot so starch helps emulsify the sauce. Don’t skimp on milk, and rest the casserole a few minutes before slicing to let everything settle without drying.
Can I use different cheeses?
Absolutely. Try sharp cheddar alone for bolder flavor, or mix in Colby Jack or Monterey Jack for extra melt. A little mozzarella adds stretch, while a handful of parmesan on top boosts savory browning.
Will ground turkey work instead of beef?
Yes. Use 93% lean turkey, add a tablespoon of olive oil to the mix for moisture, and season assertively. Bake to 165°F internal temperature; the turkey base will be lighter but still holds up under the mac.
Pro Tips for Mac and Cheese Meatloaf Casserole
- Crush crackers finely. Powdery crumbs bind better than big pieces and give a tender slice.
- Rest before cutting. Five to ten minutes firms layers for clean squares and fewer crumbs.
- Broil for color. Want extra golden cheese? Broil 30–60 seconds—watch closely to avoid scorching.
What to Serve with Mac and Cheese Meatloaf Casserole
- Simple green salad with lemony vinaigrette to cut the richness.
- Roasted broccoli or green beans for crisp, caramelized contrast.
- Garlic bread (or dinner rolls) to swipe through cheesy edges and glaze.
Storage & Reheating
Cool completely, then cover and refrigerate up to 4 days. Freeze tightly wrapped portions for 1–2 months. Reheat, covered, at 325°F until hot (add a splash of milk around the edges if needed). Microwave individual slices in short bursts, then rest a minute so the cheese re-sets and the slice stays neat.
Mac and Cheese Meatloaf Casserole
Ingredients
- 2 large eggs
- 2 pounds of lean ground beef
- 1 tablespoon granulated garlic
- 4 cups of a shredded blend of mozzarella and cheddar
- 1 cup of hickory and brown sugar-style barbecue sauce such as Sweet Baby Ray’s
- 1 teaspoon ground black pepper
- 1 teaspoon of table salt
- 2 ounces of dry onion soup seasoning mix
- 1 tablespoon onion granules
- 1 cup of classic ketchup
- 30 crushed buttery round crackers e.g., Ritz
- 10.5 ounces of condensed cheddar-style soup
- 3 cups dry elbow macaroni
- 2 cups whole milk
Instructions
- Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking dish and set aside.
- In a medium bowl, combine the ketchup and barbecue sauce until evenly blended. Reserve for later use.
- Place the lean ground beef into a large mixing bowl. Crush the crackers in a sealed plastic bag using a rolling pin, then add the crumbs to the beef.
- Incorporate the dry onion soup mix and crack the eggs directly into the bowl. Add ½ cup of the prepared ketchup-barbecue mixture.
- Using clean hands, knead the ingredients together until fully integrated. Press this mixture evenly into the greased baking dish to form the meatloaf base.
- Spread the remaining ketchup-barbecue sauce mixture across the top of the meatloaf layer.
- Bake the meatloaf uncovered for 30 minutes.
- While the meatloaf is baking, cook the elbow macaroni according to the instructions on the package. Drain thoroughly.
- In a large bowl, whisk together the milk and condensed cheddar soup until smooth and free of lumps.
- Add the salt, pepper, garlic, and onion powder into the mixture, whisking again until incorporated.
- Stir the drained macaroni into the sauce, coating all noodles evenly. Mix in 2 cups of the shredded cheese blend until well distributed.
- Once the meatloaf has finished its initial bake, remove it from the oven. Spoon the macaroni mixture over the meatloaf and spread it out evenly.
- Sprinkle the remaining 2 cups of shredded cheese across the surface.
- Return the casserole to the oven and bake for an additional 17–20 minutes, or until the cheese topping is melted and beginning to brown.
- Allow the dish to rest for a few minutes before slicing and serving.
