Finely grate the zucchini into a mesh strainer. Add 1/2 tbsp salt to extract the excess water and allow it to sit over the sink while you prep the other ingredients. Gently press down on the grated zucchini with your fingers to drain the excess liquid.
In a medium sized mixing bowl, add the ground chicken, garlic powder, red pepper flakes, parsley, oregano, egg, and drained zucchini.
Form the chicken mixture into 16 1-inch balls using a 1 tablespoon cookie scoop.
Place the meatballs in the air fryer with space in between (you might need to work in batches) and cook 10-12 minutes, turning halfway through, until fully cooked through.
