Set your air fryer to 400°F (200°C). Letting it preheat for 3 to 5 minutes ensures that the meatballs start cooking immediately and get that desired golden crust.
In a large mixing bowl, add the ground turkey, almond flour, parmesan cheese, egg, garlic powder, onion powder, oregano, salt, and pepper. Use your hands or a spatula to gently mix everything until just combined. Be careful not to overwork the meat, as this can make the meatballs tough.
Scoop about 1 to 2 tablespoons of the mixture and roll it between your palms to form a ball roughly 1.5 inches in diameter. You should get approximately 16 to 20 meatballs from the mixture.
Lightly spray the air fryer basket with olive oil. Place the meatballs in the basket in a single layer, ensuring they are not touching so the air can circulate freely. You may need to cook in batches depending on the size of your air fryer.
Cook the meatballs at 400°F for 10 to 12 minutes. Halfway through the cooking time, gently shake the basket or use tongs to turn the meatballs. Cook until the internal temperature reaches 165°F (74°C) and they are browned on the outside.
