These Mozzarella-Stuffed Turkey Meatballs pack a wonderful surprise in every bite - the center bursts with melty cheese that turns plain meatballs into something special. Using lean turkey mixed with fresh spinach and fragrant garlic makes these lighter than regular meatballs while keeping all the taste you want. After trying tons of different meatball recipes over time, my family can't get enough of these - even the kids who usually push green stuff aside gobble these up without complaint.
When I made these last weekend for the family get-together, my super picky nephew asked for more food twice. Want to know the trick? Making sure the cheese stays completely wrapped inside builds excitement with each mouthful.
Key Ingredients and Smart Shopping Advice
- Ground Turkey - Go for 93% lean to get good flavor without too much fat. I've learned that super lean turkey often leaves meatballs too dry
- Mozzarella - Those little mozzarella pearls work perfectly, but cutting up regular mozzarella is fine too. Just keep it in the fridge until you need it for easier handling
- Spinach - Use fresh spinach chopped really small. I always chop it more than it already comes, so there aren't any big pieces left
- Breadcrumbs - The Italian-flavored ones add nice taste, but regular ones are good too. I always have both crunchy panko and normal ones at home for different dishes
- Fresh Garlic - Don't use the stuff from jars - it won't taste as good. Take a minute to chop fresh garlic yourself
After making these many times, I can tell you that buying good mozzarella really changes how well these meatballs turn out.
Step-by-Step Cooking Guide
- 1. Creating Your Meatball Mix
- First, chop your spinach super tiny so it blends in completely. Mix it with your turkey meat but don't squeeze too much. Throw in your chopped garlic, grated Parmesan, breadcrumbs, egg, and spices. I prefer mixing with my hands using gentle movements instead of squeezing hard, which keeps meatballs soft.
- 2. Getting the Cheese Ready
- If you're not using those little pearl mozzarellas, cut yours into same-sized pieces. Keep them in the fridge until you need them - cold cheese is so much easier to work with and stays together better while cooking. For bigger chunks, try for about 1/2-inch squares.
- 3. Putting Them Together
- Take about 2 spoonfuls of meat mix and flatten it in your hand. Put a cheese piece right in the middle, then carefully wrap the meat all around it, making sure it's totally covered. Roll it between your hands to make a nice round ball. The most important part is making sure no cheese shows - any tiny gaps will cause leaks.
- 4. First Cooking Step
- Get your pan hot enough that water drops sizzle immediately. Add some olive oil and brown your meatballs in small batches - don't put too many in at once or they'll get steamy instead of crispy. Let them cook about 2-3 minutes on each side until they look golden before moving them to your baking tray.
- 5. Finishing in the Oven
- Bake at 375°F for 15-20 minutes. I always cut one open to check - you want the turkey fully cooked but the cheese still runny.

My mom always told me that taking your time makes the best meatballs. She wasn't wrong - hurrying usually means cheese bursting out or uneven cooking.
Mastering the Right Temperature
Turkey needs to reach 165°F inside to be safe, but be careful when checking with a thermometer - if you stick it in the cheese, you'll get the wrong reading.

Clever Prep-Ahead Ideas
You can shape your meatballs a day early and keep them in the fridge until cooking time. You can also freeze them raw on a baking sheet, then put them in a freezer bag once solid.
Keeping Leftovers Fresh
Cooked meatballs stay good in the fridge for 3-4 days. Warm them up in the oven instead of the microwave to keep them from getting rubbery.
Pro Kitchen Tricks
- Dampen your hands slightly while rolling to stop the meat from sticking
- If you notice a crack forming while rolling, start that meatball over - it's better than losing cheese during cooking
- Make a small dent in your palm when wrapping meat around cheese - it helps cover everything evenly

Closing Thoughts
These cheese-filled turkey meatballs have become more than just food in my kitchen - they show how good-for-you ingredients can turn into something you really crave. Whether you put them on pasta, stuff them in a sandwich, or eat them straight from the oven (carefully!), they prove that lighter versions of old favorites can taste just as good as the originals. The mix of lean turkey, fresh spinach, and that amazing stretchy cheese creates something that's both healthy and a bit indulgent - exactly what modern comfort food should be.
