Prepare Ingredients: Preheat your oven to 400°F (200°C). Lightly grease a large baking sheet with olive oil or line with parchment paper. In a large bowl, combine the ground turkey, breadcrumbs, Parmesan cheese, fresh parsley, milk, beaten egg, minced garlic, grated onion, oregano, salt, and black pepper. Ensure all ingredients are ready for mixing.
Mix the Meatball Mixture: Gently mix all the ingredients using your hands until just combined. Be careful not to overmix, as this can lead to tough meatballs. The mixture should be uniform but not overworked. Mixing too much can also contribute to dry meatballs.
Form the Meatballs: Roll the mixture into 1-inch to 1.5-inch balls. Aim for approximately 18-20 meatballs, ensuring they are roughly the same size for even cooking. Place the formed meatballs in a single layer on the prepared baking sheet, leaving a small space between each one.
Bake the Meatballs: Bake the Turkey Meatballs in the preheated oven for 20-25 minutes, or until they are golden brown and cooked through. The internal temperature should reach 165°F (74°C). Baking is a fantastic alternative to frying, offering a healthier option with less mess.
Serve and Enjoy: Once cooked, remove the Turkey Meatballs from the oven. Let them rest for a few minutes before serving. They are delicious on their own, with your favorite pasta sauce, or nestled in a sub roll. Enjoy your perfectly cooked, juicy Turkey Meatballs!
