Mozzarella Stuffed Meatballs

There’s something magical about a dish that looks simple on the outside but hides a warm, melty surprise inside. These Mozzarella Stuffed Meatballs are exactly that kind of comfort food: classic, familiar, and yet just a little bit extra. Imagine twirling a forkful of spaghetti, scooping up a perfectly browned meatball, and discovering a pocket of gooey mozzarella waiting inside. It’s the kind of cozy kitchen moment that makes the whole day feel better.

I love making these on chilly evenings or anytime the house needs that “Sunday dinner” aroma — savory beef, roasted garlic, and marinara bubbling gently on the stove. It’s the sort of meal that gathers everyone around the table without you even having to call them.

Ingredients

Meatball Mixture

1 pound 80% lean ground beef or half ground pork and half ground beef
1 large egg, beaten
1/4 cup breadcrumbs
1/4 cup grated Parmesan cheese
2 teaspoons minced garlic
1/4 cup finely chopped onion
3/4 teaspoon Kosher salt
1/4 teaspoon ground black pepper
2 tablespoons chopped fresh Italian parsley

Cheese Filling

4–6 ounces mozzarella, cut into 24 cubes (about 1/2-inch each)

For Serving

Marinara sauce
Cooked spaghetti noodles

Instructions

Get your oven ready.
Preheat to 400°F. Line a baking sheet with foil and mist it with nonstick spray — this keeps cleanup easy later.
Mix the meatball base.
In a large bowl, gently combine the meat, beaten egg, breadcrumbs, Parmesan, garlic, onion, salt, pepper, and parsley. Use your hands if you’re comfortable; it helps everything blend without overmixing. If the mixture feels a little dry, add a tablespoon or two of water for softness.
Portion and stuff.
Scoop the mixture onto the baking sheet in even portions. Press a cube of mozzarella into the center of each one, then shape the meat around it so the cheese is completely hidden. Roll each portion into a 1½-inch ball.
Bake to golden perfection.
Place the meatballs back on the sheet and bake uncovered for 17–20 minutes, turning them once halfway through. They should be nicely browned and cooked through, with no pink in the center.

Presentation

To make these meatballs look as irresistible as they taste, serve them nestled into warm, glossy marinara sauce. A sprinkle of extra parsley adds a fresh pop of green, and a gentle snowfall of Parmesan never hurts. If you’re serving them with spaghetti, spoon a little extra sauce over the noodles so everything feels rich and inviting.

For a charming touch, bring them to the table in a rustic, oven-safe dish — the kind that keeps the heat and makes everyone lean in closer.

Conclusion

These Mozzarella Stuffed Meatballs are the kind of comfort food that feels homemade in the best way — tender, flavorful, and full of that melty-cheese joy in every bite. They’re perfect for family dinners, date nights, or even meal-prep if you’re planning ahead. Give them a try soon… your kitchen will smell amazing, and your dinner table will thank you!
