How to Make Warm Up with a Delicious Meatball and Mashed Potato Casserole Tonight!
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
- In a large bowl, mix ground beef, breadcrumbs, Parmesan, egg, garlic, Italian seasoning, salt, and pepper until just combined. Form into 1 ½-inch meatballs.
- Place the meatballs in the baking dish and pour marinara sauce evenly over them. Cover with foil and bake for 25 minutes, until meatballs are cooked through.
- Meanwhile, boil cubed potatoes in salted water until fork-tender, about 15 minutes. Drain and mash with butter and milk until smooth and creamy.
- Once meatballs are baked, spread the mashed potatoes evenly on top, then sprinkle mozzarella cheese over the surface.
- Return the casserole to the oven uncovered, bake for another 15 minutes until cheese is melted and golden.
- Remove from oven and let rest for 5 minutes. Garnish with chopped parsley and serve warm.
Tips for the Best Results
- Use fresh, quality ground beef for juicy meatballs.
- Don’t overmix the meat mixture to keep meatballs tender.
- For extra creaminess, add a dollop of sour cream to your mashed potatoes.
- If you prefer, substitute ground turkey or chicken for the beef.
- Let the casserole rest after baking to set before serving.

Frequently Asked Questions
Can I make this casserole ahead of time?
Absolutely! You can prepare the meatballs and mashed potatoes separately in advance, then assemble and bake the casserole when ready. This saves time on busy days.
What can I use instead of mozzarella cheese?
Cheddar, Monterey Jack, or a blend of Italian cheeses work well here. Choose one that melts nicely for a gooey, delicious topping.
Is it possible to make this recipe gluten-free?
Yes, simply substitute gluten-free breadcrumbs and check the marinara sauce ingredients to ensure they contain no gluten. The rest of the recipe is naturally gluten-free.
Can I add vegetables to this casserole?
Definitely! Stir cooked spinach, mushrooms, or diced bell peppers into the marinara sauce before baking for added nutrition and flavor.
