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.

An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).
Cooking Frozen Meatballs in the Oven. Preheat your oven to 350 degrees. Pull out the desired number of meatballs from the freezer and line them up on your cookie sheet, evenly spaced apart. Place the cookie sheet with the meatballs on it on the center rack in the oven. Set your kitchen timer to 30 minutes and take it with you if you are going leave the room, or at least make sure that you will be able to hear it from where you are at.
