Preheat oven to 400°F. Line a large baking sheet with parchment paper or spray with olive oil spray. Set aside.
Add all of the ingredients to the bowl of a food processor. Blend on high for 30 seconds to 1 minute or until the mixture is combined and starts to pull away from the sides of the bowl.
1 lb ground chicken, 2 cups finely grated or chopped sweet potatoes, 2 tablespoons tapioca flour, arrowroot starch or cornstarch, 1 1/2 teaspoons onion powder, 1 teaspoon EACH: paprika, garlic powder, and kosher salt
Use a tablespoon to scoop out the mixture and place ½ inch apart on the prepared baking sheet. Use your hands to form the mixture into chicken nugget shapes. You should have about 18-21 chicken nuggets. The mixture will be wet and sticky. Dip your fingers in water to keep them from sticking while you shape the nuggets.
Bake chicken nuggets in the preheated oven for 18 to 20 minutes, turning halfway through, until the internal temperature reaches 165°F. Broil for the last 2 minutes for a crispier exterior.
Cool slightly and serve with your favorite sauce like sugar-free ketchup, BBQ sauce, honey mustard or sriracha.
