These mozzarella stuffed meatballs are comfort food at its best. Imagine a golden, juicy meatball that breaks open to reveal a gooey, melty center. They’re simple enough for a weeknight and special enough for guests.
Serve them over pasta, tuck them into a sub roll, or plate them with a simple salad. However you serve them, they’re a crowd-pleaser that never disappoints.
Ingredients
Method
-
Prep the cheese: Cut low-moisture mozzarella into small cubes and pat them dry with paper towels. Keep them chilled so they stay firm while you work.
-
Make a panade: In a large bowl, stir together breadcrumbs and milk until the crumbs are damp.
Let it sit for 2–3 minutes to form a soft paste that keeps the meatballs tender.
-
Build the mixture: Add ground beef, ground pork, grated onion, minced garlic, eggs, Parmesan, chopped parsley, salt, pepper, and a pinch of red pepper flakes. Mix gently with your hands until just combined.
-
Shape the meatballs: Scoop about 2 tablespoons of meat mixture into your palm. Flatten slightly, tuck a mozzarella cube in the center, and wrap the meat around it.
Roll into a smooth ball, sealing any cracks. Repeat with the remaining mixture.
-
Brown the meatballs: Heat a slick of olive oil in a large skillet over medium-high. Brown the meatballs in batches for 2–3 minutes per side until they develop color.
Don’t cook through yet.
-
Simmer in sauce: Pour marinara into a wide pot or Dutch oven and bring to a gentle simmer. Nestle the browned meatballs in the sauce, cover partially, and simmer 15–20 minutes until cooked through (165°F at the center).
-
Rest and serve: Let the meatballs rest 5 minutes to settle the juices. Serve over pasta, on polenta, or in toasted rolls.
Spoon extra sauce on top and finish with Parmesan and parsley.

How to Store
- Fridge: Store cooled meatballs with sauce in an airtight container for up to 4 days. Reheat gently on the stovetop or in the microwave until hot.
- Freezer: Freeze cooked meatballs (with or without sauce) for up to 3 months. Thaw overnight in the fridge, then warm in sauce on low heat.
- Make-ahead: Assemble raw stuffed meatballs and refrigerate up to 24 hours before cooking.
For longer storage, freeze raw on a baking sheet, then transfer to a bag and cook from frozen, extending cooking time slightly.
Health Benefits
- Protein-rich: The combination of beef, pork, and mozzarella delivers a solid boost of protein to keep you full.
- Calcium from cheese: Mozzarella adds calcium that supports bone health without an overly heavy flavor.
- Iron and B vitamins: Red meat brings iron and B12, which support energy levels and overall wellness.
- Control over ingredients: Making your own lets you manage sodium, choose leaner meats, and add herbs instead of sugar-heavy sauces.
- Balanced meal potential: Pair with a salad, whole-grain pasta, or roasted vegetables for a well-rounded plate.
Pitfalls to Watch Out For
- Cheese leakage: Gaps in the meat seal lead to melted mozzarella escaping. Pinch and smooth any cracks before cooking.
- Overmixing: Working the meat too much makes tough meatballs. Mix just until combined and keep a light touch.
- Dry texture: Skipping the panade or using very lean meat can make them dry.
Use the breadcrumb-milk mix and include some fat in the meat.
- Boiling sauce: A hard boil can break the meatballs and split the cheese. Keep the sauce at a gentle simmer.
- Big cheese cubes: Oversized cubes can push through the meat or prevent even cooking. Aim for about 3/4-inch pieces.
Recipe Variations
- Turkey or chicken: Swap in ground turkey or chicken.
Add an extra tablespoon of olive oil and don’t skip the panade to keep them moist.
- Herb-forward: Add chopped basil and oregano, or use Italian seasoning for a more aromatic profile.
- Spicy: Mix in hot Italian sausage or increase red pepper flakes. A pinch of smoked paprika adds depth.
- Gluten-free: Use gluten-free breadcrumbs or ground oats. Check that your marinara is gluten-free as well.
- Cheese swap: Try provolone or a low-moisture fontina for a different melt and flavor.
- Baked method: Arrange on a parchment-lined sheet, mist with oil, and bake at 400°F for 15–18 minutes, then finish by simmering in sauce for 5–10 minutes.
FAQ
Can I use fresh mozzarella?
Fresh mozzarella has more moisture and can leak or make the meatballs soggy.
Low-moisture mozzarella is best for a clean melt and easier sealing.
Do I need both beef and pork?
No, but the combo gives great texture and flavor. If using only beef, choose 80/20 and make sure to keep the panade for tenderness.
How do I know they’re done?
Use an instant-read thermometer. The center should reach 165°F.
If you don’t have one, cut one open after simmering; the meat should be fully cooked with melted cheese inside.
Can I cook them entirely in the oven?
Yes. Bake at 400°F until browned and nearly cooked through, 15–18 minutes, then simmer briefly in marinara to finish and add moisture.
What’s the best way to reheat?
Warm gently in marinara over low heat until hot. This keeps the meatballs moist and helps the cheese re-melt without drying out.
Can I make them smaller for appetizers?
Absolutely.
Use about 1 tablespoon of meat with a smaller cheese cube. Reduce simmer time by a few minutes.
In Conclusion
Mozzarella stuffed meatballs bring together everything people love about Italian-style comfort food: savory meat, fragrant herbs, and a cheesy surprise. They’re simple, flexible, and perfect for family dinners or casual entertaining.
With a few smart tips and a gentle simmer in sauce, you’ll get meatballs that are tender, flavorful, and irresistibly melty in the center. Make a batch, stash some in the freezer, and you’ll be set for easy, satisfying meals any time.
