Preheat Oven: Set your oven to 400°F. Line a baking sheet with foil or coat it with nonstick cooking spray.
Sauté Vegetables: Heat olive oil in a small skillet over medium heat. Add diced onion and minced garlic. Sauté for 5-7 minutes, or until onions are translucent.
Prepare Stuffing Mix: In a small bowl, combine the stuffing mix with chicken broth. Let it sit for 5 minutes to rehydrate. Lightly mash with a fork to break up any large chunks.
Mix Ingredients: In a large bowl, combine the sautéed onion and garlic with the stuffing mixture, ground turkey, beaten egg, salt, poultry seasoning, and parsley (if using). Gently mix until just combined—avoid overmixing.
Form Meatballs: Shape the mixture into 20 meatballs, each about 3 tablespoons in size. Place them on the prepared baking sheet, spacing them 1-2 inches apart.
Bake: Cook for 14-16 minutes, or until the internal temperature reaches 165°F. For extra browning, you can broil the meatballs for an additional 2-3 minutes.
Serve: Enjoy with herbed gravy.
