Ingredients (US Measurements)

  • 1 lb ground beef (or half beef, half pork for more flavor and moisture)

  • 1 cup fresh spinach, finely chopped

  • 3 cloves garlic, minced

  • 1/4 cup breadcrumbs

  • 1/4 cup grated Parmesan cheese

  • 1 large egg

  • 1/2 tsp salt

  • 1/4 tsp black pepper

  • 1/2 tsp Italian seasoning

  • 1 cup mozzarella cheese, cut into 1/2-inch cubes

  • 2 tbsp olive oil (for pan-frying or baking tray)

Stage-by-Stage Instructions

Stage 1: Prepare the Meatball Mixture

  1. Start with quality meat. Use fresh ground beef or a 50/50 mix of beef and pork. The pork adds fat and flavor, helping to keep the meatballs juicy.

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

  3. Use your hands or a spoon to gently mix everything together. Don’t overwork it—overmixing can result in tough meatballs.

Tip: Use day-old bread ground into crumbs for a richer flavor. You can also use panko for a lighter texture.

Stage 2: Stuff with Mozzarella

  1. Take about 1 to 2 tablespoons of the meat mixture and flatten it into a small disk in your palm.

  2. Place one cube of mozzarella in the center.

  3. Wrap the meat around the cheese and roll it gently into a ball. Ensure the cheese is fully enclosed.

  4. Place rolled meatballs on a plate or parchment-lined tray. Continue until all meat is used.

Tip: Use part-skim mozzarella for less grease or fresh mozzarella pearls for added creaminess.

Stage 3: Cook the Meatballs

Option A: Pan-Frying

  1. Heat olive oil in a large skillet over medium heat.

  2. Add meatballs in batches. Do not overcrowd the pan.

  3. Cook each meatball for 4–5 minutes per side, turning to ensure even browning and thorough cooking.

  4. Once browned, transfer to a plate lined with paper towels to absorb excess oil.

Option B: Baking (Healthier Option)

  1. Preheat oven to 400°F (200°C).

  2. Arrange meatballs on a baking sheet lined with parchment or foil.

  3. Drizzle with olive oil or spray with nonstick spray.

  4. Bake for 18–22 minutes or until golden and cooked through.

Tip: Use a thermometer—meatballs are done when the internal temperature reaches 165°F (74°C).

Stage 4: Serve

  1. Serve meatballs hot and melty. Great on their own or with dipping sauces.

  2. Garnish with fresh basil, parsley, or more grated Parmesan.

  3. Pair with spaghetti, creamy mashed potatoes, or crusty garlic bread for a full meal.

Flavor Variations and Additions

  • Spicy Kick: Add red pepper flakes or a diced jalapeño to the meat mix.

  • Mushroom Lovers: Add finely chopped sautéed mushrooms into the meat blend.

  • Low Carb: Swap breadcrumbs for almond flour or crushed pork rinds.

Expert Tips

  • Chilling Before Cooking: Chill stuffed meatballs in the fridge for 20 minutes before cooking to help them hold shape better.

  • Perfect Browning: Don’t move the meatballs too much while frying—they need time to develop a golden crust.

  • Double Batch: Make extra and freeze them; future you will thank you.

  • Uniform Size: Use a small cookie scoop to ensure evenly sized meatballs, which cook more consistently.

Common Mistakes to Avoid

  1. Overmixing the meat mixture – This can make the meatballs tough.

  2. Using low-fat cheese – It won’t melt well and can be rubbery.

  3. Skipping the seal – Always make sure the cheese is completely covered to prevent leaks.

  4. Cooking too fast – High heat can brown the outside before the inside is cooked.
