Ingredients You’ll Need
- Ground beef 80/20: The fat content keeps the meatballs juicy and flavorful during baking. Look for a bright cherry red color at the store.
- Ground pork: Adds moisture and a deeper savory flavor to the beef blend. Choose fresh pork that looks pink and firm.
- Italian seasoned breadcrumbs: Soaked in milk, these create a tender texture that prevents dry meatballs. The seasoning adds built-in herb flavor.
- Whole milk: Hydrates the breadcrumbs to form a paste that locks in moisture. Always use whole milk for the best richness.
- Large egg: Acts as the binder that holds your meatballs together. Use fresh eggs that sink in water.
- Grated Parmesan cheese: Brings salty, nutty umami to the meat mixture. Freshly grated cheese melts and blends better than pre-shredded.
- Fresh garlic cloves: Minced garlic infuses every bite with aromatic warmth. Always choose firm cloves with no green sprouts.
- Fresh parsley: Finely chopped parsley adds a fresh, clean herbal note. It balances the richness of the meat and cheese.
- Dried oregano: Provides that classic Italian-American herb flavor. Crush it between your fingers before adding to release the oils.
- Kosher salt: Essential for bringing out all the savory flavors in the meat. Coarse salt distributes more evenly than fine salt.
- Black pepper: Adds a gentle heat and complexity to the seasoning. Freshly ground pepper has much more punch than pre-ground.
- Fresh mozzarella cubes: The star ingredient that creates the molten cheese center. Always use fresh mozzarella packed in water for the best melt.
- Olive oil: Needed to sear the meatballs and create a flavorful fond in the pan. Extra virgin olive oil adds the best flavor.
- Marinara sauce: Creates the saucy base that cooks the meatballs and adds moisture. A good quality jarred sauce works perfectly here.
- Fresh basil leaves: Optional garnish that adds a bright, peppery finish to the finished dish. Tear them by hand to prevent bruising.
- Additional Parmesan: Extra cheese for serving is always a welcome addition. More nutty flavor makes every bite better.
- Red pepper flakes: For those who like a little heat with their comfort food. Add a pinch at the table for customization.
How to Make It
Preheat and Prepare:
Start by preheating your oven to 400°F. Line a large baking sheet with parchment paper or aluminum foil for easy cleanup later. This temperature ensures the meatballs cook through while the cheese inside gets perfectly melty.
Soak the Breadcrumbs:
In a small bowl, combine the breadcrumbs and milk. Let this mixture sit for about 5 minutes until the breadcrumbs absorb the liquid and become pasty. This step is crucial for keeping your meatballs tender instead of dense.
Mix the Meat Base:
In a large mixing bowl, add the ground beef, ground pork, soaked breadcrumbs, egg, Parmesan, minced garlic, parsley, oregano, salt, and pepper. Gently mix with your hands until just combined – overmixing creates tough meatballs. The mixture should hold together but not be overworked.
Form and Stuff the Meatballs:
Take about 2 tablespoons of the meat mixture and flatten it in your palm. Place one cube of mozzarella in the center, then carefully wrap the meat around it, sealing completely. Roll into a smooth ball about 1.5 inches in diameter. Repeat with the remaining meat and cheese until all 12 meatballs are formed.
Sear for Flavor:
Heat olive oil in a large oven-safe skillet over medium-high heat. Working in batches, sear the meatballs for 2-3 minutes per side until golden brown. They don’t need to be cooked through yet, but this step creates flavorful fond in the pan that will deepen your sauce.
Build the Sauce:
Remove the meatballs from the skillet and drain any excess fat. Pour the marinara sauce into the skillet, then carefully return the meatballs to the sauce, turning them to coat evenly. The sauce should surround but not completely submerge the meatballs.
Bake to Perfection:
Transfer the skillet to the preheated oven and bake for 15-18 minutes. The meatballs are done when they reach an internal temperature of 165°F and the cheese inside is fully melted. Use an instant-read thermometer for accuracy.
Rest Before Serving:
Let the meatballs rest in the sauce for 5 minutes after removing them from the oven. This allows the molten cheese to set slightly so it doesn’t all pour out when you cut into them. The residual heat will finish cooking the meatballs perfectly.
You Must Know

Storage Tips
Store leftover mozzarella stuffed meatballs in an airtight container in the refrigerator for up to 4 days. To reheat, place them in a saucepan with a splash of marinara sauce over medium-low heat until warmed through, about 8-10 minutes. You can also freeze them for up to 3 months by freezing individually on a tray first, then transferring to freezer bags. When reheating from frozen, let them thaw in the fridge overnight or add extra sauce and cook gently on the stovetop.
Ingredient Substitutions
If you can’t find fresh mozzarella packed in water, low-moisture mozzarella will work but won’t be quite as gooey. For a gluten-free version, use gluten-free breadcrumbs or crushed gluten-free crackers instead. To make dairy-free mozzarella stuffed meatballs, substitute the cheese with dairy-free mozzarella shreds and omit the Parmesan – the texture will be slightly different but still delicious. For a lighter version, you can use ground turkey instead of beef and pork, but you’ll need to add a tablespoon of olive oil to the mixture to keep it moist.
Serving Suggestions
Serve these mozzarella stuffed meatballs over spaghetti or penne pasta with extra marinara sauce for the ultimate comfort meal. Pair with garlic bread for dipping into that incredible cheese and sauce mixture. For a lighter option, try serving them over zucchini noodles or with a simple arugula salad dressed with lemon vinaigrette. They also make amazing meatball subs on toasted hoagie rolls with melted provolone on top. I love serving them with roasted vegetables like broccoli or bell peppers for a complete weeknight dinner.

Frequently Asked Questions
To prevent leaks, use fresh mozzarella cubes that are cold from the fridge. Ensure the meat mixture fully encases the cheese and pinch the seams tightly. Cooking the meatballs immediately after forming helps maintain their shape.
Yes, you can substitute ground turkey or chicken, but these meats are leaner. To prevent dry Mozzarella Stuffed Meatballs, consider adding a tablespoon of olive oil to the ground poultry or slightly reducing the cook time to keep them moist.
Both methods work well for Mozzarella Stuffed Meatballs. Baking is easier for large batches and uses the olive oil listed in the ingredients. Pan-frying creates a delicious crust but requires more attention to ensure the cheese doesn’t burn.
Since the meat is a blend of beef and pork, cook until the internal temperature reaches 160°F (71°C). The meatballs should be browned on the outside, and the cheese inside will be melted and gooey.
These meatballs are a main dish staple. Serve them over spaghetti or zucchini noodles with extra marinara sauce. They are also delicious in a sub roll with melted provolone for a meatball sandwich.
