Ingredients

• 1 pound ground beef or turkey
• 1/2 cup breadcrumbs
• 1/4 cup grated Parmesan cheese
• 1 egg
• 2 cloves garlic, minced
• 1 teaspoon Italian seasoning
• Salt and pepper to taste
• 2 cups mashed potatoes (prepared)
• 1 cup marinara sauce
• 1 cup shredded mozzarella cheese
• 2 tablespoons olive oil
• Fresh parsley for garnish (optional)

How To Make Meatball Mashed Potato Casserole

Step 1: Prepare the Meatball Mixture

In a large mixing bowl, combine the ground beef or turkey with breadcrumbs, grated Parmesan cheese, egg, minced garlic, Italian seasoning, salt, and pepper. Use your hands or a spoon to mix thoroughly until all ingredients are evenly incorporated.

Step 2: Form and Cook the Meatballs

Shape the mixture into small, bite-sized meatballs—about 1 inch in diameter works best for even cooking. Heat the olive oil in a large skillet over medium heat. Add the meatballs in batches, making sure not to overcrowd the pan. Cook for about 5-7 minutes, turning occasionally, until they are browned on all sides and cooked through. Remove from heat and set aside.

Step 3: Assemble the Casserole

Preheat your oven to 375°F (190°C). In a baking dish, spread the prepared mashed potatoes evenly on the bottom. Then, layer the cooked meatballs over the mashed potatoes. Pour the marinara sauce evenly over the meatballs and potatoes, ensuring good coverage.

Step 4: Add Cheese and Bake

Sprinkle the shredded mozzarella cheese evenly over the top of the casserole. Place the dish in the oven and bake for 20-25 minutes, or until the cheese is melted, bubbly, and golden around the edges.

Step 5: Garnish and Serve

Remove the casserole from the oven and let it cool slightly. Garnish with fresh parsley if desired before serving. This dish pairs wonderfully with a fresh green salad or steamed vegetables for a complete meal.

Expert Tips

• For extra juicy meatballs, avoid overmixing the meat mixture as it can make the meatballs dense.
• If you prefer a spicier flavor, add a pinch of red pepper flakes to the meatball mixture or marinara sauce.
• Use leftover mashed potatoes to make this dish even quicker. Just make sure they are creamy and well-seasoned.
• To save time, you can bake the meatballs in the oven at 400°F (200°C) for 15-20 minutes instead of pan-frying.
• For an even richer flavor, mix a little garlic powder or onion powder into the mashed potatoes.
• Make sure to use a good quality marinara sauce or homemade sauce for the best taste.
• Try layering some sautéed onions or mushrooms between the meatballs and mashed potatoes for added depth.

Variations and Customizations

• Swap mozzarella for cheddar or provolone cheese for a different cheesy profile.
• Use ground chicken instead of beef or turkey for a lighter option.
• Mix fresh herbs like basil or oregano into the meatball mixture for a fresh twist.
• Add a layer of sautéed spinach or kale under the mashed potatoes for extra greens.
• Use sweet potatoes instead of regular mashed potatoes to add natural sweetness and color.
• Top the casserole with breadcrumbs mixed with melted butter for a crunchy crust.
