Sheet Pan Meatball Gnocchi with Marinara and Mozzarella

This sheet pan meatball gnocchi brings together juicy beef meatballs, pillowy potato gnocchi, and sweet red peppers in a rich marinara sauce, all topped with a golden blanket of mozzarella and parmesan. Everything bakes together on one pan, so the gnocchi soak up the sauce while the cheese turns bubbly and browned. It's the kind of dinner that feels indulgent but comes together in minutes.

This recipe turns a handful of store-bought ingredients into a comforting, one-pan dinner that looks and tastes like it took much more effort. The gnocchi bake directly in the marinara, becoming tender and flavorful, while the meatballs stay juicy and the peppers soften just enough to add sweetness.

A generous layer of mozzarella and parmesan melts into a golden, bubbling crust that makes every bite irresistible. Whether you're feeding a family or just want leftovers for lunch, this sheet pan dinner is as simple as it gets. Serve it straight from the pan for a relaxed, satisfying meal.

Ingredients

Why this recipe works

Baking everything on a single sheet pan allows the flavors to meld together as the sauce reduces and the cheese browns. The gnocchi absorb the marinara as they cook, becoming soft and savory without needing to boil them separately.

The high oven temperature ensures the cheese melts quickly and develops those delicious golden spots, while the meatballs stay moist and the peppers turn tender. This method cuts down on dishes and cleanup, making it a practical choice for busy evenings.

The combination of marinara, mozzarella, and parmesan is a classic Italian-American flavor trio that pairs perfectly with both meatballs and gnocchi. The gnocchi act like tiny pillows that catch the sauce and cheese, creating a satisfying texture contrast with the hearty meatballs and crisp-tender peppers.

Because everything cooks together, the juices from the meatballs and peppers season the entire dish, so every bite is well-rounded. This is comfort food at its easiest and most delicious.

Notes and substitutions

For the best results, use precooked beef meatballs — either from the refrigerated section or frozen. If using frozen, there's no need to thaw them first; just add a few extra minutes to the baking time.

The gnocchi can be shelf-stable or refrigerated; both work well. Avoid using fresh gnocchi that requires boiling, as it may become too soft in the oven. Choose a good-quality marinara sauce that you enjoy eating on its own, since it's a major flavor component.

A rimmed sheet pan is essential to catch the bubbling sauce and prevent spills. Line it with parchment for easy cleanup. The red bell peppers add color and sweetness, but you can swap in other colors or use a mix. For the cheese, a combination of low-moisture mozzarella and parmesan gives the best melt and flavor. If you prefer a spicier kick, use a marinara with red pepper flakes or add a pinch of chili flakes before baking.
