Ingredients You’ll Need
For the Meatballs
- 1 1/2 pounds (680 g) ground beef: Choose ground beef with some fat for tender, flavorful meatballs.
- 1/2 cup (about 50 g) plain breadcrumbs: Helps bind the mixture and retain moisture.
- 1/3 cup (80 ml) milk: Softens the breadcrumbs.
- 1 large egg: Helps bind the ingredients.
- 1/2 cup (50 g) freshly grated Parmesan cheese: Adds savory flavor.
- 2 garlic cloves: Finely minced.
- 2 tablespoons chopped fresh parsley: Or 2 teaspoons dried parsley.
- 1 teaspoon Italian seasoning: Adds classic herb flavor.
- 1 teaspoon salt: Adjust to taste.
- 1/2 teaspoon black pepper: Freshly ground if possible.
- 8 ounces (225 g) low-moisture mozzarella: Cut into approximately 18 small cubes.
- 1–2 tablespoons olive oil: For browning the meatballs.
For the Marinara Sauce
- 24 ounces (680 g) marinara sauce: Homemade or store-bought.
- 1/2 teaspoon dried oregano: Optional, for extra herbal flavor.
- Fresh basil or parsley: For garnish.
- Extra grated Parmesan: Optional, for serving.
How to Make Cheesy Stuffed Meatballs
Step 1: Prepare the Mozzarella
Cut the mozzarella into small cubes, approximately 1/2 inch (1.25 cm) each. Pat the cheese dry if it has excess moisture. Keep the cubes chilled while preparing the meat mixture to make them easier to handle.
Step 2: Soak the Breadcrumbs
Place the breadcrumbs in a large mixing bowl and pour in the milk. Let them stand for about 5 minutes until softened. This helps create a tender meatball mixture instead of a dense one.
Step 3: Mix the Meatball Ingredients
Add the ground beef, egg, Parmesan, minced garlic, parsley, Italian seasoning, salt, and black pepper to the softened breadcrumbs.
Mix gently with clean hands or a fork until the ingredients are just combined. Avoid overmixing, which can make the meatballs firm and dense.
Step 4: Stuff the Meatballs with Cheese
Divide the meat mixture into approximately 18 equal portions. Flatten one portion in your palm and place a mozzarella cube in the center.
Carefully fold the meat around the cheese and roll it into a ball. Pinch any seams closed and check that no cheese is visible. Repeat with the remaining meat mixture and mozzarella.
Important tip: Do not make the cheese cubes too large. Smaller pieces are easier to seal inside the meat and reduce the chance of the cheese leaking during cooking.
Step 5: Chill the Meatballs
Arrange the shaped meatballs on a plate or tray and refrigerate them for 15–30 minutes if time allows. Chilling helps the meatballs hold their shape during browning.
Step 6: Brown the Meatballs
Heat the olive oil in a large skillet over medium to medium-high heat. Add the meatballs in batches, leaving space between them.
Turn them carefully until several sides are browned, about 5–7 minutes in total depending on their size. They do not need to be fully cooked at this stage because they will finish cooking in the sauce.
Step 7: Add the Marinara Sauce
Reduce the heat to medium-low. Pour the marinara sauce around the browned meatballs and add the oregano if desired. Gently spoon some sauce over the meatballs.
Step 8: Simmer Until Cooked Through
Cover the skillet and simmer gently for approximately 15–20 minutes, turning the meatballs carefully once if needed. Cooking time depends on their size and the heat of your stove.
For food safety, check the center of a meatball with a food thermometer. Ground beef should reach at least 160°F (71°C). If using ground poultry instead, cook it to 165°F (74°C).
Step 9: Garnish and Serve
Remove the skillet from the heat and let the meatballs rest for a few minutes. Sprinkle with fresh basil or parsley and extra Parmesan if desired.
Serve hot over spaghetti, with garlic bread, or alongside roasted vegetables. When you cut into a meatball, the mozzarella center should be soft and melted.
Tips for the Best Cheese-Stuffed Meatballs
- Use low-moisture mozzarella: It is easier to handle and generally releases less liquid than fresh mozzarella.
- Seal every meatball carefully: Check for cracks and exposed cheese before cooking.
- Do not overmix: Combine the ingredients only until evenly distributed.
- Brown in batches: Overcrowding the pan can cause the meatballs to steam instead of brown.
- Simmer gently: A vigorous boil can cause the meatballs to break apart and the cheese to escape.
- Use a thermometer: Color alone cannot reliably tell you whether ground meat is fully cooked.
- Let them rest briefly: A short rest helps the meatballs settle before serving.
Easy Variations
Beef and Pork Cheesy Meatballs
Replace part of the ground beef with ground pork. A mixture of beef and pork creates a different flavor and texture. Keep the mozzarella cubes small and seal them completely inside the meat.
Turkey Mozzarella-Stuffed Meatballs
Use ground turkey instead of beef. Because lean turkey can dry out more easily, avoid overmixing and check the internal temperature carefully. Ground turkey must reach 165°F (74°C).
Spicy Cheese-Stuffed Meatballs
Add a pinch of red pepper flakes or a little chili powder to the meat mixture. You can also choose a spicy marinara sauce for extra heat.
Cheesy Meatballs Without Marinara
Brown and bake the meatballs until cooked through, then serve them with garlic butter, roasted vegetables, or a dipping sauce of your choice. Always verify the safe internal temperature before serving.
What to Serve with Cheesy Stuffed Meatballs
- Spaghetti: A classic pairing with marinara sauce and Parmesan.
- Garlic bread: Perfect for soaking up the tomato sauce.
- Mashed potatoes: A comforting option for a hearty dinner.
- Roasted vegetables: Broccoli, zucchini, or bell peppers balance the richness.
- Green salad: A crisp salad with a light vinaigrette adds freshness.
- Meatball subs: Place the meatballs in toasted rolls with sauce and extra mozzarella.
How to Store and Reheat Leftovers
Let the meatballs cool slightly, then transfer them with the sauce to a shallow airtight container. Refrigerate within two hours and use within 3–4 days.
To reheat, warm the meatballs and sauce in a covered skillet over medium-low heat until hot throughout. Add a small splash of water if the sauce has thickened too much. You can also microwave individual portions in a microwave-safe dish, stirring or turning the meatballs as needed for even heating.
For longer storage, freeze the cooked meatballs with their sauce in a freezer-safe container. For best quality, use within about 3 months. Thaw in the refrigerator before reheating, and heat until steaming hot throughout.
Frequently Asked Questions
Why does the cheese leak out of my meatballs?
The meat may not be sealed tightly around the cheese, or the cheese cubes may be too large. Use small cubes, close every seam, and avoid cooking the meatballs at an excessively high temperature.
Can I bake cheese-stuffed meatballs instead?
Yes. Arrange the stuffed meatballs on a lightly greased baking sheet and bake at 400°F (200°C), checking their internal temperature as they cook. Depending on their size, they may take around 18–25 minutes. Add them to warm marinara sauce after baking if desired.
Can I prepare the meatballs ahead of time?
Yes. Shape and stuff the meatballs, cover them, and refrigerate for up to one day before cooking. Keep them cold and cook them thoroughly before serving.
What cheese works best inside meatballs?
Low-moisture mozzarella is a reliable choice because it melts well and is easy to cut into small cubes. Provolone can also work, although the flavor and melting behavior will differ.
Can I freeze cheese-stuffed meatballs?
Yes. Freeze cooked meatballs with the sauce in a freezer-safe container. You can also freeze uncooked shaped meatballs, but keep them properly sealed and thaw them safely in the refrigerator before cooking.
What is the best way to serve these meatballs for a party?
Serve them in a warm dish with marinara sauce and toothpicks, or keep them warm in a slow cooker after cooking. Make sure the meatballs remain at a safe serving temperature.
