How to Make Cheesy Potato Meatball Casserole Recipe
Step 1: Prepare the Meatball Mixture
Start by combining your ground beef, breadcrumbs, Parmesan cheese, chopped parsley, egg, garlic powder, salt, and black pepper in a large bowl. Mixing these ingredients thoroughly ensures each meatball will be packed full of flavor and held together just right. This step is where your casserole’s rich, savory foundation begins!
Step 2: Shape and Brown the Meatballs
Roll the mixture into small, bite-sized meatballs about 1 inch in diameter—perfect for even cooking. Heat the olive oil in a skillet over medium heat, then cook the meatballs in batches. Brown them on all sides, which locks in their juices and gives them a lovely crust. This stage is all about building flavor and texture that will shine through once baked.
Step 3: Prepare the Creamy Mashed Potato Layer
While your meatballs are cooling a bit, mix together the prepared mashed potatoes with sour cream, milk, butter, garlic powder, onion powder, salt, and pepper. This mixture should be silky, fluffy, and packed with creamy, savory goodness that will perfectly complement the meatballs and cheese in your casserole.
Step 4: Assemble the Casserole
Spread half of the mashed potato mixture evenly in a casserole dish. Next, nestle the browned meatballs on top, distributing them so every bite will have a bit of meaty goodness. Spoon the marinara sauce evenly over the meatballs, adding just a hint of tang and moisture. Top everything with the remaining mashed potatoes, then sprinkle the shredded cheddar and mozzarella cheeses generously over the top. This layering creates a beautiful medley of flavors and textures once baked.
Step 5: Bake Until Bubbly and Golden
Place your casserole in a preheated oven at 375°F (190°C) and bake for about 25 to 30 minutes until the cheese is bubbling and lightly golden on top. This step finishes the casserole off by melding all the flavors together and creating that irresistible crust of melted cheese that makes this Cheesy Potato Meatball Casserole Recipe so unforgettable.
How to Serve Cheesy Potato Meatball Casserole Recipe

Garnishes
Fresh parsley sprinkled over the top not only adds a pop of vibrant green to brighten up your casserole but also lends a fresh herbal note that balances the richness perfectly. A dollop of sour cream on the side can enhance creaminess even further and bring a touch of cool tang to each bite.
Side Dishes
This hearty dish pairs wonderfully with a light green salad tossed in a citrus vinaigrette or some steamed vegetables like green beans or broccoli. These sides add freshness and crunch, making your meal balanced and well-rounded.
Creative Ways to Present
For a fun spin, serve individual portions of the casserole in small ramekins topped with additional cheese and a cherry tomato for color. Alternatively, you can add a sprinkle of crispy bacon bits or caramelized onions on top for an extra layer of flavor and texture that will impress your guests.
Make Ahead and Storage
Storing Leftovers
Once cooled, store any leftover casserole tightly covered in the refrigerator for up to 3 days. This dish reheats beautifully and keeps its creamy, cheesy texture well, making it a perfect next-day meal.
Freezing
If you want to save it for longer, this casserole freezes nicely. Wrap it securely in plastic wrap and aluminum foil or use an airtight container, then freeze for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating
To reheat, warm the casserole in a preheated oven at 350°F (175°C) for 20-25 minutes until heated through and bubbly again. You can also microwave individual portions, but the oven method helps maintain the best texture and flavor.
FAQs
Can I use ground turkey instead of beef?
Absolutely! Ground turkey is a great leaner alternative that works just as well in this Cheesy Potato Meatball Casserole Recipe. It absorbs all the herbs and spices nicely, making the dish just as delicious.
Can I make the meatballs ahead of time?
Yes! You can prepare and cook the meatballs a day ahead and store them in the fridge. This can make assembling the casserole faster and less stressful when you’re ready to cook.
What if I don’t have marinara sauce?
No worries. You can substitute with plain tomato sauce, a bit of canned diced tomatoes, or a simple mixture of tomato paste thinned with a little water and seasoned with Italian herbs.
Can I use instant mashed potatoes instead of homemade?
Of course! While homemade mashed potatoes add a richer flavor, good-quality instant mashed potatoes can be a convenient shortcut without compromising much on taste or texture.
Is this casserole suitable for freezing after it’s baked?
It’s best to freeze this casserole before baking for the best texture and quality. Freezing after baking is possible but the texture of the potatoes and cheese may change slightly when reheated.

This Cheesy Potato Meatball Casserole Recipe is a true crowd-pleaser that combines so many comforting elements in one dish.
