See Recipe Card Below This Post For ingtedient Quantites
- Whole milk: Keeps the breadcrumbs moist and helps create tender meatballs that don't dry out during cooking.
- Italian breadcrumbs: Acts as a binder and adds a little extra flavor to the meat mixture.
- Ground meat: Use beef, pork, chicken, turkey, or a mix. I usually combine half ground beef and half Italian sausage for the best flavor.
- Minced garlic: Adds a savory depth that makes the meatballs taste homemade and delicious.
- Minced Italian parsley: Brings a fresh, herby note that brightens up the meat.
- Large egg: Binds everything together so the meatballs hold their shape while cooking.
- Salt: Enhances all the flavors in the meat mixture.
- Black pepper: Adds a gentle kick of warmth.
- String cheese: The secret to that gooey, melty center. Cut each stick into four 1-inch pieces for easy stuffing.
- Olive oil: Used for browning the meatballs and building flavor before they simmer in the sauce.
- Marinara sauce: Choose your favorite store-bought version or make your own for a fresher taste.
- Grated Parmesan cheese: Optional, but it adds a salty, nutty finish when sprinkled on top.
- Garlic bread: Also optional, but highly recommended for dipping into all that marinara.
How to Make Mozzarella Stuffed Meatballs
Follow these steps to make perfect Mozzarella Stuffed Meatballs every time.
Soak the breadcrumbs: In a small bowl, combine the milk and Italian breadcrumbs. Let the mixture sit for about 5 minutes so the breadcrumbs soften and absorb the liquid.
Mix the meat: In a large bowl, combine the soaked breadcrumb mixture with the ground meat, minced garlic, parsley, egg, salt, and black pepper. Use your hands to mix everything together gently until just combined. Don't overwork it, or the meatballs will turn out dense and tough.
Form and stuff: Divide the meat mixture into eight equal portions. Roll each portion into a ball, then press a piece of string cheese into the center. Pinch the meat around the cheese to seal it completely so none of the cheese leaks out during cooking.
Brown the meatballs: Heat the olive oil in a large skillet over medium-high heat. Once the oil shimmers, add the meatballs in batches and brown them on all sides, about 6 to 8 minutes total. Transfer the browned meatballs to a plate and wipe the skillet clean.
Simmer in sauce: Pour the marinara sauce into the same skillet. Return the meatballs to the skillet and gently toss them to coat with the sauce. Cover the skillet with a lid and reduce the heat to low. Let the meatballs simmer for about 10 minutes, until they're cooked through and tender.
Serve: Top the meatballs with grated Parmesan cheese and a sprinkle of fresh parsley. Serve with crusty garlic bread for dipping into the sauce.
Substitutions and Variations
Use different cheeses: Swap mozzarella for provolone, cheddar, or pepper jack if you want a different flavor profile.
Make them spicy: Add a pinch of red pepper flakes to the meat mixture or use spicy marinara sauce.
Go gluten-free: Use gluten-free breadcrumbs and check that your marinara is gluten-free.
Try different meats: Ground chicken or turkey work well if you're looking for a leaner option.
Add more herbs: Fresh basil or oregano can be mixed into the meat for extra Italian flavor.
Bake instead of browning: Skip the stovetop browning step and bake the meatballs at 375°F for 20 minutes before adding them to the sauce.
Equipment For Mozzarella Stuffed Meatballs
- Small mixing bowl: For soaking the breadcrumbs in milk.
- Large mixing bowl: For combining the meat mixture.
- Large skillet with lid: Essential for browning the meatballs and simmering them in the sauce.
- Measuring cups and spoons: To keep your ingredient ratios accurate.
- Plate: For holding the browned meatballs before they go back into the sauce.
- Spoon or spatula: For stirring and turning the meatballs as they cook.
Storage and Reheating Tips
Refrigerator: Store leftover meaMozzarella Stuffed Meatballs tballs in an airtight container with the marinara sauce for up to 4 days. The flavors actually get better as they sit.
Freezer: Freeze cooked meatballs in a freezer-safe container for up to 3 months. Let them cool completely before freezing.
Reheating: Warm the meatballs gently in a skillet over low heat, or microwave them in 30-second intervals until heated through. Add a splash of water or extra marinara if the sauce thickens too much.
Make ahead: You can form the uncooked, Mozzarella Stuffed Meatballs and refrigerate them for up to 24 hours before browning and simmering.
Expert Tips
Don't skip the milk soak: Soaking the breadcrumbs in milk keeps the meatballs moist and tender. It's a small step that makes a big difference.
Seal the cheese well: Make sure the meat completely covers the cheese so it doesn't leak out while cooking.
Use room-temperature ingredients: Let the egg and milk sit out for a few minutes before mixing. It helps everything combine more evenly.
Brown in batches: Don't overcrowd the skillet, or the meatballs will steam instead of getting a nice brown crust.
Simmer gently: Keep the heat low once the Mozzarella Stuffed Meatballs are in the sauce. High heat can make them tough.
Taste the meat mixture: If you're nervous about seasoning, cook a tiny piece of the meat mixture in a pan and taste it before forming all the meatballs.

FAQ
Can you put mozzarella cheese in meatballs?
Yes, absolutely. Mozzarella melts beautifully inside meatballs and creates that gooey, stretchy texture everyone loves. Just make sure to seal the meat around the cheese so it doesn't leak out.
Can you put cheese inside meatballs?
You can stuff meatballs with almost any cheese that melts well. Mozzarella, provolone, cheddar, and pepper jack all work great. Just cut the cheese into small pieces and tuck them into the center before cooking.
What cheese melts best inside meatballs?
Mozzarella is the classic choice because it melts smoothly and stretches when you cut into the meatball. String cheese is especially convenient since it's already portioned into easy-to-use sticks.
Do meatballs need to be cooked before putting in sauce?
Browning the meatballs first adds flavor and helps them hold their shape, but it doesn't fully cook them. Simmering them in the sauce finishes the cooking and lets the Mozzarella Stuffed Meatballs soak up all that delicious marinara flavor.
