1 Combine turkey, bread crumbs, spinach, egg, onion powder, and garlic powder together in a bowl. Roll mixture into palm-size meatballs and place 2 inches apart on a baking sheet.  Bake in the preheated oven until no longer pink in the center and outside is browned, 15 to 20 minutes. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).
How long do you cook meatballs and at what temperature? Bake at 350 degrees until cooked through, between 15 and 35 minutes, depending on the size of the meatball and your particular oven. The surest method is to use a meat thermomâ¦eter, with the internal temperature being at least 165 degrees Fahrenheit. Making the world better, one answer at a time.
