Ingredients and Their Role in the Recipe

• 1 small onion, grated: Adds natural sweetness and moisture to the meatballs, ensuring they stay tender.
• 1/2 cup fresh flat-leaf parsley, chopped: Infuses the meatballs with fresh, herbaceous notes that balance the richness of the beef and cheese.
• 2/3 cup grated Parmesan cheese: Adds salty, nutty depth and helps bind the meat mixture.
• 1/3 cup Italian bread crumbs: Provide structure and absorb moisture so the meatballs hold together while baking.
• 1 large egg: Acts as a natural binder, keeping all ingredients together while contributing richness.
• 2 tablespoons marinara sauce plus 1/3 cup: Brings tangy tomato flavor into the meat mixture and provides a flavorful base for baking.
• 3 garlic cloves, minced: Adds aromatic depth and a punch of savory flavor.
• 1 pinch crushed red pepper flakes: Offers a subtle heat that enhances the overall taste without overwhelming.
• Salt and pepper to taste: Essential for seasoning the meatballs perfectly.
• 1 package ground beef (1.5-2 lbs): The primary protein, providing the hearty, juicy base for the meatballs.
• 16 cubes mozzarella cheese (1/2 inch): The star of the dish, creating a melty, cheesy center that elevates these meatballs to unforgettable levels.

Step-by-Step Instructions for Perfect Baked Mozzarella Stuffed Meatballs

1. Preheat the oven: Position the rack in the lower third of your oven and preheat to 400°F (200°C). This ensures even baking and a slightly caramelized bottom.
2. Prepare the meatball mixture: In a large mixing bowl, combine the grated onion, chopped parsley, Parmesan cheese, bread crumbs, egg, 2 tablespoons of marinara, minced garlic, crushed red pepper flakes, salt, and pepper. Mix thoroughly to evenly distribute flavors.
3. Add the ground beef: Incorporate the beef into the mixture, using your hands for the best results. Mix gently to combine without overworking the meat, which keeps the meatballs tender.
4. Form the meatballs: Divide the mixture into 16 equal portions. Roll each portion into a ball, creating a smooth, compact surface. This will ensure even baking and a beautiful presentation.
5. Stuff with mozzarella: Make a small indentation in the center of each meatball. Insert a cube of mozzarella and carefully reform the meatball to completely enclose the cheese. Properly sealing the cheese prevents it from leaking during baking.
6. Prepare the baking dish: Spoon 1/3 cup of marinara sauce into the bottom of a baking dish, spreading it evenly. This acts as a flavorful base that prevents the meatballs from sticking and keeps them moist.
7. Place and drizzle: Arrange the meatballs in the dish and drizzle lightly with extra virgin olive oil. This promotes a slightly golden exterior while retaining juiciness inside.
8. Bake to perfection: Place the dish in the oven and bake for 15 minutes, or until meatballs are cooked through and the internal temperature reaches 160°F (71°C). The mozzarella inside should be perfectly melted, creating a delightful cheese pull when served.

Why These Meatballs Are Loved

These Baked Mozzarella Stuffed Meatballs are adored for multiple reasons. The combination of tender ground beef, aromatic herbs, and molten mozzarella creates a burst of flavor with every bite. They are also visually appealing—perfectly round, golden on the outside, and oozing cheesy goodness on the inside. Unlike fried meatballs, baking ensures a lighter texture while still keeping them moist and succulent.

Pro Tips for Perfect Mozzarella Stuffed Meatballs

• Use fresh mozzarella cubes: Fresh cheese melts beautifully and creates that classic gooey texture inside each meatball.
• Don’t overmix the meat: Overworking can result in dense meatballs. Mix gently until just combined.
• Seal the cheese carefully: Press the meat around the mozzarella firmly to prevent leakage during baking.
• Preheat your baking dish: Warm it slightly to encourage even cooking and prevent sticking.
• Try a thermometer: To avoid overcooking, check that the meatballs reach an internal temperature of 160°F (71°C).
