• 1 cup breadcrumbs: Binds the meat mixture and adds structure for perfectly shaped meatballs.
• 1/4 cup grated Parmesan cheese: Sharp, salty kick that enhances umami in every bite.
• 1/4 cup chopped fresh parsley: Fresh herbaceous notes that lighten and brighten the meatball mixture.
• 1/2 teaspoon garlic powder: Savory depth and gentle garlicky aroma throughout the meat.
• 1/2 teaspoon onion powder: Adds sweet onion flavor without adding extra moisture.
• 1 large egg: Acts as a binder, holding all the ingredients together in the meatballs.
• Salt and pepper to taste: Essential seasoning to balance flavors and boost taste.
• 2 cups mashed potatoes (homemade or store-bought): Creamy topping that forms a comforting layer.
• 1 cup marinara sauce: Tangy base that coats the meatballs and keeps them moist.

How To Make Meatball and Mashed Potato Bake

Ready to assemble this hearty bake? Follow these straightforward steps to craft juicy meatballs, layer them with zesty marinara, and top with creamy mashed potatoes and gooey cheese for a dinner that feels like a warm hug.

1. Preheat your oven to 375°F (190°C). This ensures even cooking from the start.

2. In a large bowl, combine the ground beef, breadcrumbs, Parmesan cheese, parsley, garlic powder, onion powder, egg, salt, and pepper. Mix thoroughly with your hands or a spatula until ingredients are fully integrated.

3. Form the mixture into meatballs about 1 inch in diameter, aiming for 16–20 evenly sized balls. Place them on a baking sheet lined with parchment paper.

4. Bake the meatballs for 15–20 minutes or until they’re browned and cooked through, reaching an internal temperature of 160°F (71°C).

5. While the meatballs bake, prepare the mashed potatoes if making from scratch: boil peeled and diced potatoes until tender, about 15–20 minutes, then drain and mash with butter, milk, salt, and pepper.

6. Spread half of the marinara sauce on the bottom of a baking dish, creating a sauce bed for the meatballs.

7. Remove the cooked meatballs from the oven and nestle them into the sauce in the baking dish.

8. Spoon the remaining marinara over the meatballs, ensuring each one is well coated.

9. Carefully spread the mashed potatoes over the meatballs and sauce, smoothing the top with a spatula to create an even layer.

10. Sprinkle the shredded mozzarella cheese evenly over the mashed potatoes, then dust with Italian seasoning for extra flavor.

11. Return the baking dish to the oven and bake for an additional 20–25 minutes or until the cheese is melted and bubbly.

12. Remove from the oven and let the bake rest for a few minutes. Garnish with extra parsley if desired before serving.
