This Meatball and Mashed Potato Bake is what I reach for on busy nights when my family craves something filling yet fuss free. Just picture juicy meatballs cozied up under a cloud of buttery mashed potatoes and all of it bubbling with melted cheese. It is the culinary equivalent of a warm blanket on a chilly evening and has saved more than a few weeknights in my kitchen when everyone is hungry and tired.
I whipped up this bake on a whim one night with leftover mashed potatoes and a bag of frozen meatballs. It was such a hit that now it is a permanent fixture in our dinner rotation. There is never a single bite left when my kids are at the table.
Ingredients
- Meatballs: fully cooked homemade or frozen Look for ones with little filler for a meatier texture
- Mashed potatoes: creamy and fluffy are best If using leftovers give them a stir with a splash of milk for fresh taste
- Brown gravy: rich and savory Choose homestyle or make your own for best flavor
- Shredded mozzarella or cheddar cheese: for a melty topping Freshly shredded melts best and gives a richer taste
- Salt and pepper: to taste Use flaky sea salt for finishing if you have it
- Optional parsley or green onions: for garnish Adds a fresh pop of color and brightness Sprinkle right before serving
Step-by-Step Instructions
- Prepare the Oven:
- Preheat your oven to three hundred seventy five degrees F so everything cooks evenly
- Build the Meatball Layer:
- Lightly grease a baking dish and spread the meatballs in a single layer making sure they are not crowded This helps them heat evenly and soak up the gravy
- Add the Gravy:
- Pour the brown gravy over the meatballs and gently mix to coat each one well Try to get the gravy into all the spaces for full flavor
- Spread the Mashed Potatoes:
- Spoon the mashed potatoes over the meatball mixture and smooth with a spatula for an even layer You want to create a seal so the gravy stays underneath
- Add the Cheese:
- Sprinkle the shredded cheese generously over the mashed potatoes covering every inch This is what gives you the golden bubbling crust
- Bake to Perfection:
- Put the dish on the center rack and bake uncovered for twenty five to thirty minutes until the top is golden and the edges are bubbling
- Let It Rest and Serve:
- Take out of oven and let sit for a few minutes before scooping This helps everything set up Garnish with a sprinkle of parsley or green onions for freshness

The cheese layer on top is always the part my family fights over and I have learned the hard way to go a little heavy with it No one complains about extra cheese at our house and it always makes this dish feel extra special Around the holidays this bake brings everyone to the kitchen before it even comes out of the oven The smell is irresistible
Storage Tips
Cool any leftovers completely then cover tightly before refrigerating They will keep for three days and reheat beautifully in the oven or microwave If you want to freeze the whole bake assemble it but hold off on the cheese layer until ready to bake Wrap it tightly and freeze for up to two months
