Mac and Cheese Meatloaf Casserole–two favorite dinners combined into one amazing dish! Meatloaf is baked with macaroni and cheese on top. The Instant Pot speeds up the prep process.
Mac and Cheese Meatloaf Casserole
Don’t knock it until you try it! This mac and cheese meatloaf casserole was there one minute and completely devoured the next! We all agreed that it was delicious and something we should have often. To make this casserole you will start by patting meatloaf mixture into an 8×8 inch baking dish and popping it into the oven. While the meatloaf bakes you’ll make fast and easy macaroni and cheese in your Instant Pot. The two will get done close to the same time. At that point the macaroni and cheese is spooned on top of the meatloaf and then baked for a few more minutes. The cheesy macaroni cheese pairs perfectly with the baked meatloaf.
A few notes…
- This is an easy recipe to double and bake in a 9×13 inch dish if you’re feeding a crowd. Double all the ingredients and keep the cooking time the same.
- The meatloaf recipe I used is quick and easy. It only has 6 ingredients. If you prefer you can use your own favorite meatloaf recipe.
- I suggest using a lean or extra lean ground beef (I used 90% lean) so that the meatloaf doesn’t get too greasy.
- You can use another type of pasta like shells, cavatappi or bowties in the place of elbow macaroni.
- Use your favorite barbecue sauce. I like Sweet Baby Ray’s BBQ sauce the best.
- I like using sharp or extra sharp cheddar for maximum cheese flavor.

- While meatloaf is baking make the mac and cheese in the Instant Pot. Pour 2 cups water into Instant Pot. Sprinkle in the macaroni. Add in the butter, kosher salt, onion powder, garlic powder and pepper.
