Step-by-Step Instructions
Prepare the Meatball Mixture:
Step 1: Combine the Base In a large mixing bowl, gently combine ground beef or turkey, finely chopped spinach, minced garlic, panko breadcrumbs, grated Parmesan, and egg using clean hands—this gentle method keeps the texture tender.
Step 2: Season Perfectly Add oregano, basil, salt, and pepper to the mixture, combining just until ingredients are evenly distributed. Don’t overmix, as this can make meatballs tough.
Create the Stuffed Meatballs:
Step 3: Prepare the Cheese Cut mozzarella into ¾-inch cubes and chill in refrigerator for 10-15 minutes to make stuffing easier and prevent melting during handling.
Step 4: Form and Stuff Take about 2 tablespoons of meat mixture and flatten in your palm. Place one mozzarella cube in the center, then carefully wrap the meat around it, sealing completely to prevent cheese from leaking during cooking.
Step 5: Shape Consistently Roll each stuffed portion into a smooth ball, ensuring the cheese is completely enclosed. You should have about 12-16 meatballs depending on size.
Cook to Perfection:
Step 6: Heat the Oil In a large skillet over medium heat, warm 2-3 tablespoons olive oil until it shimmers but doesn’t smoke.
Step 7: Brown the Meatballs Add meatballs to the skillet in batches, avoiding overcrowding. Cook for 8-10 minutes, turning occasionally to achieve golden brown color on all sides.
Step 8: Finish Cooking Reduce heat to low, cover the skillet, and cook for an additional 5-7 minutes until meatballs are cooked through (internal temperature 165°F) and cheese is melted inside.
Serve:
Step 9: Rest and Plate Let meatballs rest for 2-3 minutes to allow cheese to set slightly, then serve immediately over pasta, with marinara sauce, or as desired.

Make-Ahead Tips
Perfect for Meal Prep These meatballs are incredibly freezer-friendly for busy weeknight solutions:
Freezing Cooked Meatballs Cool completely, place on baking sheet until frozen solid, then transfer to freezer bags for up to 3 months. Reheat in marinara sauce.

Spinach Garlic Meatballs Stuffed with Mozzarella FAQs
Can I bake these instead of pan-frying? Yes! Bake at 400°F for 20-25 minutes on a lined baking sheet, finishing under the broiler for crispy exterior if desired.
What if the cheese leaks out during cooking? Ensure meat is completely sealed around cheese, and chill formed meatballs for 15 minutes before cooking to help cheese stay put.
Can I use frozen spinach instead of fresh? Yes, but thaw completely and squeeze out excess moisture first. Fresh spinach provides better texture and color.
How do I know when they’re fully cooked? Internal temperature should reach 165°F, and juices should run clear. The cheese inside should be completely melted.
Can I make these dairy-free? Use your favorite dairy-free mozzarella alternative and nutritional yeast instead of Parmesan for similar flavors.
