How to Make Cheesy Potato Meatball Casserole Recipe
Step 1: Prepare and Cook the Meatballs
Start by combining ground beef, breadcrumbs, Parmesan, parsley, egg, garlic powder, salt, and pepper in a large bowl. Mixing everything thoroughly ensures your meatballs are flavorful and hold together beautifully. Shape the mixture into small, one-inch meatballs — the perfect bite size for layering. Heat olive oil in a skillet and brown the meatballs on all sides until cooked through. Browning adds that irresistible crust and locks in juices, so don’t rush through this part. Once cooked, set them aside while you prepare the next layers.
Step 2: Mix Your Creamy Mashed Potato Layer
In a large bowl, combine your prepared mashed potatoes with shredded cheddar, mozzarella, sour cream, milk, butter, garlic powder, onion powder, salt, and pepper. This mixture brings a rich, creamy texture that contrasts wonderfully with the hearty meatballs. Stir everything until smooth and uniform — this will be the luscious base and top layer of your casserole.
Step 3: Assemble the Layers
Grease a 9×13-inch baking dish and spread half of the mashed potato mixture evenly across the bottom. Then, nestle the cooked meatballs in a single layer over the potatoes, making sure each bite will have some meaty goodness. Finally, cover the meatballs completely with the remaining mashed potato mixture. This layering technique locks in moisture and creates a stunning presentation once baked.
Step 4: Add the Finishing Touches and Bake
Drizzle the marinara sauce over the top of the casserole for a tangy counterpoint to the creamy potatoes and savory meatballs. If you’re a cheese lover, sprinkle a little extra shredded cheese over everything for a bubbly, golden crust. Pop the dish into a preheated oven at 375°F (190°C) and bake for 25 to 30 minutes until the top is beautifully browned and bubbling with cheesy goodness.
How to Serve Cheesy Potato Meatball Casserole Recipe

Garnishes
Fresh parsley isn’t just for looks — it adds a burst of freshness that cuts through the richness of the casserole. A sprinkle of chopped parsley right before serving is a simple way to brighten the dish with color and flavor.
Side Dishes
Serving this casserole with a crisp green salad or steamed vegetables balances the hearty flavors with some lightness and crunch. Roasted Brussels sprouts or green beans tossed with a little lemon juice and olive oil also make for excellent companions.
Creative Ways to Present
Try serving individual portions in small ramekins for a charming presentation at dinner parties. You can also prepare this casserole in muffin tins for portable, single-serving bites great for potlucks or lunches on the go. Adding a swirl of marinara or a drizzle of pesto on top can add a delightful visual and flavor twist.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover the casserole tightly with plastic wrap or foil and refrigerate for up to 3 days. The flavors actually deepen after sitting, making leftovers even tastier.
Freezing
The Cheesy Potato Meatball Casserole Recipe freezes beautifully. Assemble the casserole in a freezer-safe dish, cover well, and freeze for up to 2 months. Thaw overnight in the fridge before baking as usual.
Reheating
Reheat leftovers in the oven at 350°F (175°C) covered with foil to prevent drying out, for about 20 minutes or until heated through. You can also microwave single servings, but the oven method helps retain that fresh-out-of-the-oven texture.
FAQs
Can I use ground turkey instead of beef?
Absolutely! Ground turkey works wonderfully in this recipe and offers a lighter alternative without sacrificing flavor or texture.
Can I make the mashed potatoes from scratch?
Yes, homemade mashed potatoes will elevate this casserole even more. Just make sure they’re creamy and well-seasoned to complement the meatballs and cheese.
What if I don’t have marinara sauce?
You can substitute with tomato sauce or even a mild salsa, depending on your taste preferences. The sauce adds acidity and moisture to the dish, so feel free to get creative.
Is it possible to make this casserole vegetarian?
For a vegetarian version, try using meatless meatballs or hearty vegetable patties and vegetable broth-based mashed potatoes. The cheeses and potatoes still provide plenty of comfort and flavor.
How spicy is the casserole?
This recipe is mild, making it great for all ages. You can add red pepper flakes or chopped jalapeños to the meat mixture if you’d like to introduce a little kick.
