In a small bowl, combine paprika, chili powder, garlic powder, onion powder, erythritol, salt and black pepper.
Place drumsticks in a large bowl and pour melted butter over the chicken.
Sprinkle prepared seasoning over the drumsticks and toss to coat.
Preheat your air fryer to 375F. Grease an air fryer basket with olive oil and arrange seasoned drumsticks inside. Inset the basket in the air fryer and cook for 20 minutes, flipping halfway. You may need to cook the chicken drumsticks in batches, depending on the size of your air fryer.
When the cooking time ends, take the drumsticks out and serve with your favorite sauce and some leafy greens.
