Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

1 lb (450 g) ground beef or a mix of beef and ground turkey
1 cup fresh spinach, finely chopped
3 cloves garlic, minced
1/2 cup breadcrumbs
1/4 cup grated Parmesan cheese
1 large egg
2 tbsp fresh parsley, chopped
1 tsp Italian seasoning
1/2 tsp salt
1/4 tsp black pepper
6 to 8 small mozzarella balls or mozzarella cubes
2 tbsp olive oil for cooking
Optional: 1 1/2 cups marinara sauce for serving

Optional for extra moisture:

1/4 cup milk

Directions

Prepare the meatball mixture
In a large mixing bowl, combine the ground meat, chopped spinach, garlic, breadcrumbs, Parmesan cheese, egg, parsley, Italian seasoning, salt, and black pepper. If you want softer meatballs, add the milk at this stage. Mix gently using your hands or a spoon until everything is evenly combined. Avoid overmixing to keep the meatballs tender.
Shape and stuff the meatballs
Scoop a golf ball-sized amount of the mixture and flatten it slightly in your palm. Place one mozzarella ball or cube in the center. Carefully wrap the meat mixture around the cheese and roll into a smooth ball, making sure the cheese is fully sealed inside. Repeat with the remaining mixture and cheese.
Cook the meatballs
Heat olive oil in a large skillet over medium heat. Place the meatballs into the skillet, leaving a little space between each one. Cook for about 12 to 15 minutes, turning occasionally so they brown evenly on all sides. The meatballs should be fully cooked and golden brown.
Optional marinara simmer
For extra flavor, pour marinara sauce into the skillet once the meatballs are cooked. Let them simmer gently for about 5 minutes until the sauce is warm and flavorful.
Serve
Serve hot with a sprinkle of fresh parsley. These meatballs pair perfectly with pasta, mashed potatoes, roasted vegetables, or toasted slider buns.

FAQs

Can I use frozen spinach instead of fresh spinach?

Yes, frozen spinach works well. Make sure to thaw it completely and squeeze out excess moisture before adding it to the mixture.

How do I keep the mozzarella from leaking out?

Seal the meat mixture tightly around the cheese and avoid cracks in the meatballs before cooking.

Can I bake these meatballs instead of frying them?

Yes, bake them at 400°F (200°C) for about 20 minutes until fully cooked.

What type of mozzarella works best?

Small mozzarella balls or firm mozzarella cubes work best because they melt nicely without releasing too much liquid.

Can I prepare the meatballs ahead of time?

Yes, you can shape the meatballs and refrigerate them uncooked for up to 24 hours before cooking.

What should I serve with these meatballs?

They are delicious with pasta, garlic bread, salad, rice, or inside sandwich rolls.

Can I make this recipe gluten-free?

Yes, simply replace regular breadcrumbs with gluten-free breadcrumbs.

How do I know when the meatballs are cooked through?

The internal temperature should reach 165°F (74°C), and the meatballs should no longer be pink inside.

Can I freeze uncooked meatballs?

Yes, freeze them on a tray first, then transfer to a freezer-safe container once solid.

Why are my meatballs dry?

Overmixing the meat or overcooking can make them dry. Adding milk also helps keep them moist.
