Combine milk and breadcrumbs in a small bowl, then let it sit for 2 minutes until the breadcrumbs absorb the liquid. This creates a paste that keeps your turkey meatballs recipe incredibly moist and tender. Meanwhile, preheat your oven to 400°F and line a baking sheet with parchment paper for easy cleanup.
In a large mixing bowl, combine the ground turkey, eggs, Parmesan cheese, onion, minced garlic, fresh parsley, oregano, salt, black pepper, and smoked paprika. Don't overmix — I learned this the hard way when I stirred too vigorously and ended up with dense, tough meatballs. Gently fold in the milk and breadcrumb mixture until everything's just combined.
Roll the mixture into 20 meatballs about the size of a golf ball, placing them on your prepared baking sheet with a little space between each one. Bake at 400°F for 18-20 minutes until they're golden brown on the outside and cooked through. The internal temperature should reach 165°F when checked with a meat thermometer.
Remove from the oven and let them cool for 2-3 minutes before serving or transferring to a container. They'll continue to firm up slightly as they cool, so don't panic if they seem a little soft right out of the oven. This turkey meatballs recipe stays warm on the counter for about 15 minutes.
For marinara sauce, combine your meatballs with about 2 cups of marinara in a skillet over medium heat for 5 minutes until they're coated and warmed through. Stir occasionally so they heat evenly. The sauce absorbs into the meatballs and makes them even more flavorful.
If you're making meatball subs, toast your rolls lightly in a 350°F oven for 3-4 minutes before filling them. Layer the warm turkey meatballs recipe with sauce and melted cheese for the ultimate sandwich. I personally like adding fresh basil right before serving.
For meal prep, let the cooked meatballs cool completely before storing them in an airtight container in the refrigerator for up to 4 days. You can reheat them gently in the microwave for 60-90 seconds or in a 325°F oven for about 10 minutes. Frozen meatballs last up to 3 months.
