This Meatball and Mashed Potato Bake delivers everything you want in a cozy dinner creamy mashed potatoes savory meatballs brown gravy and a gooey cheese topping all layered together in one comforting dish. It is my favorite solution for using up leftover potatoes or giving simple store bought meatballs a flavor boost. This bake really is a family favorite that feels like a treat but comes together fast.
I made this during a busy work week to clear out the fridge and my family immediately asked for it again the next night. It has become our go to Sunday meal when we want something that feels special but is easy enough for a weeknight.

Step by Step Instructions
- Preheat the Oven:
- Set your oven to 375 degrees Fahrenheit so it is fully heated when you assemble the dish This helps the bake cook evenly and the cheese brown beautifully
- Prepare the Baking Dish:
- Lightly grease your baking dish with butter or nonstick spray This prevents sticking and makes cleanup easier
- Arrange the Meatballs:
- Place the fully cooked meatballs evenly across the bottom of your dish If using frozen make sure they are thawed and heated through so the bake does not get watery
- Add the Gravy:
- Pour your brown gravy carefully over the meatballs Gently stir to ensure each meatball is coated this will keep them juicy and flavorful during baking
- Layer the Mashed Potatoes:
- Using a spoon or spatula spread the mashed potatoes in an even layer all the way to the edges If using leftover potatoes warm them slightly first so they are easy to spread
- Top with Cheese:
- Generously sprinkle the shredded cheese across the mashed potatoes Try to cover the whole top for the best crust
- Bake Until Golden:
- Place the dish uncovered in the oven and bake for twenty five to thirty minutes Watch for the cheese to bubble and the edges to turn golden brown
- Rest and Garnish:
- After removing from the oven let it sit for a few minutes so the layers set up This makes serving cleaner Scatter parsley or green onions over the top for color and freshness

My favorite part is the way mozzarella melts into little golden pockets across the top It always reminds me of cozy winter weekends when everyone asked for seconds before their plates were even empty This is a dish that honestly never gets old in our home
Storage Tips
Leftovers keep well in an airtight container in the fridge for up to three days Warm in the oven at three hundred and fifty degrees for about twenty minutes covered so it stays moist For longer storage freeze individual portions wrapped tightly and reheat from frozen for a quick meal
Ingredient Substitutions
Try turkey or plant based meatballs for a lighter version For a dairy free option swap in vegan cheese and use olive oil mashed potatoes The cheese blend can be changed to whatever you like Swiss provolone or pepper jack all add fun flavor twists
Serving Suggestions
I love to add a crisp green salad tossed in vinaigrette or simple steamed broccoli to balance the richness This meal also goes well with roasted carrots If you want a bigger feast serve alongside a loaf of crusty bread to soak up extra gravy
