Why You’ll Love This Recipe

These aren’t your ordinary meatballs.

Each one hides a delicious cube of mozzarella inside, creating a creamy surprise that pairs perfectly with the savory meat. Fresh spinach adds color, nutrition, and a subtle earthy flavor, while garlic and Parmesan bring extra depth to every bite.

Best of all, they’re incredibly versatile. Serve them over spaghetti, with crusty garlic bread, alongside mashed potatoes, or enjoy them on their own with a generous spoonful of marinara sauce.

Ingredients

• 1 lb (450 g) ground beef (or a beef and pork blend)
• 1 cup fresh spinach, finely chopped
• 2–3 garlic cloves, minced
• 1 large egg
• 1/2 cup breadcrumbs
• 1/2 cup grated Parmesan cheese
• 1 teaspoon Italian seasoning
• Salt and freshly ground black pepper, to taste
• 1 cup mozzarella cheese, cut into small cubes
• 2 cups marinara sauce
• Olive oil for browning

How to Make Spinach & Garlic Mozzarella Meatballs

Step 1: Prepare the Meat Mixture

In a large mixing bowl, combine the ground meat, chopped spinach, garlic, breadcrumbs, Parmesan, egg, Italian seasoning, salt, and pepper.

Mix everything gently until just combined. Overmixing can make the meatballs dense, so keep it light.

Step 2: Stuff with Mozzarella

Take a small handful of the meat mixture and flatten it in your palm.

Place a cube of mozzarella in the center, then carefully wrap the meat around the cheese, sealing it completely before rolling it into a smooth ball.

Repeat until all the meatballs are formed.

Step 3: Brown the Meatballs

Heat a drizzle of olive oil in a large skillet over medium-high heat.

Brown the meatballs on all sides for several minutes. They don’t need to be fully cooked yet—this step simply locks in flavor and creates a delicious golden crust.

Step 4: Bake in Marinara Sauce

Spread the marinara sauce across the bottom of a baking dish.

Arrange the browned meatballs over the sauce, cover loosely with foil, and bake at 400°F (200°C) for 25–30 minutes, or until the meatballs are fully cooked and the cheese inside is perfectly melted.

Allow them to rest for a few minutes before serving.

Tips for Perfect Meatballs Every Time

• Seal the mozzarella completely inside each meatball to prevent cheese from leaking out.
• Don’t overwork the meat mixture—gentle mixing keeps the texture tender.
• Browning the meatballs before baking adds extra flavor and helps them stay juicy.
• Chill the mozzarella cubes before stuffing to reduce the chance of early melting.
• Use freshly grated Parmesan whenever possible for the best flavor.

Serving Ideas

These cheesy meatballs pair beautifully with:

• Classic spaghetti and marinara
• Garlic bread or toasted baguette
• Creamy mashed potatoes
• Buttered rice
• Roasted vegetables
• A fresh green salad

They’re also delicious tucked into a toasted sub roll for an unforgettable meatball sandwich.

Make Ahead & Storage

These meatballs are perfect for meal prep.

You can assemble and freeze them before cooking. Once frozen solid, transfer them to a freezer-safe bag and store for up to three months. Bake directly from frozen, simply adding a few extra minutes to the cooking time.

Leftovers will keep in the refrigerator for 3–4 days and reheat beautifully in the oven, air fryer, or microwave.
