Preparation Phase & Tools to Use

Before diving in, get your tools ready—having the right equipment makes prep smoother and ensures the best texture.

Mixing Bowls: You’ll need a large one for combining meatball ingredients and a smaller one for your egg mix.
Baking Sheet or Cast Iron Skillet: For browning the meatballs. A skillet adds that golden crust before simmering.
Tongs or Slotted Spoon: Helpful for turning meatballs while browning or transferring to sauce.
Cheese Grater or Pre-Cubed Mozzarella: Use fresh mozzarella cubes for the perfect molten center.
Dutch Oven or Saucepan: For simmering meatballs in marinara until tender and infused with flavor.
Thermometer (optional): To ensure the meat is fully cooked (internal temp of 160°F for beef).

Prep everything before you start rolling to stay organized and ensure each step flows easily. Keeping your hands slightly wet while shaping the meatballs also helps prevent sticking.

Ingredients for the Stuffed Meatballs with Mozzarella Cheese

Let’s break down what you need and why each ingredient matters in creating the perfect cheesy meatball.

Ground Beef (80/20): The fat content ensures the meatballs stay juicy and flavorful.
Breadcrumbs: Acts as a binder and gives the meatballs a tender texture.
Parmesan Cheese: Adds a nutty, savory depth to the meat mixture.
Fresh Garlic: Enhances the overall flavor with a bold, aromatic punch.
Fresh Parsley: Adds freshness and a pop of color.
Egg: Binds everything together to keep the meatballs from falling apart.
Salt & Pepper: Essential for seasoning and balance.
Italian Seasoning: Brings in those traditional herb flavors of oregano, basil, and thyme.
Mozzarella Cheese Cubes: The gooey heart of the meatballs.
Olive Oil: For browning the meatballs, adding extra flavor and a crisp exterior.
Marinara Sauce: Provides a rich, tomatoey base to simmer and serve the meatballs in.

How To Make the Stuffed Meatballs with Mozzarella Cheese

Step 1: Mix the Meatball Base

In a large bowl, combine the ground beef, breadcrumbs, grated Parmesan, minced garlic, chopped parsley, egg, salt, pepper, and Italian seasoning. Mix gently with your hands until just combined—don’t overwork it.

Step 2: Stuff with Mozzarella

Take a scoop of the meat mixture (about 2 tablespoons), flatten it in your palm, and place a cube of mozzarella in the center. Fold the meat around the cheese and roll gently into a ball.

Step 3: Brown the Meatballs

In a large skillet or cast iron pan, heat olive oil over medium heat. Sear the meatballs on all sides until nicely browned. This step locks in moisture and adds flavor.

Step 4: Simmer in Marinara Sauce

Transfer the browned meatballs to a saucepan or Dutch oven with warm marinara sauce. Cover and simmer on low for 20-25 minutes, allowing the meatballs to fully cook and soak up the rich tomato flavor.

Step 5: Serve and Enjoy

Once cooked through, serve the meatballs over pasta, on sub rolls, or on their own with extra sauce and a sprinkle of Parmesan.

How to Serve and Store Stuffed Meatballs with Mozzarella Cheese

These mozzarella-stuffed meatballs are incredibly versatile and pair well with a variety of dishes. Serve them hot over spaghetti, tucked inside a toasted sub roll with melted provolone, or plated solo with a sprinkle of Parmesan and fresh basil.

For a dinner party or appetizer platter, arrange them on skewers or in a bowl with toothpicks for easy grabbing. Garnish with chopped parsley or red pepper flakes for a pop of color and heat.

Storage Tips:

Refrigerator: Store cooled meatballs in an airtight container with sauce for up to 4 days.
Freezer: Flash-freeze cooked meatballs on a baking sheet, then transfer to freezer bags. Keep for up to 3 months.
Reheating: Warm in the oven at 350°F or gently simmer in marinara on the stovetop until heated through.
