Preheat the oven to 400ºF and line a large rimmed baking sheet with parchment paper.
In a large bowl, combine the ground turkey, sweet potato, salt, thyme, garlic powder, and black pepper.
Use a fork to mix the ingredients until the mixture looks relatively uniform.
Use a 1-ounce cookie scoop to portion the meatball mixture and drop it onto the lined baking sheet.
Repeat with the remaining mix to create about 24-28 balls.
Use wet hands to shape the balls, if needed.
Bake the meatballs at 400ºF for 15 minutes, or until the center of the meatballs reaches 165ºF with an instant-read thermometer.
Serve the meatballs warm in your favorite sauce.
Leftovers can be stored in an airtight container in the fridge for up to 4 days.
