Preheat your air fryer on the “air fry” mode at 375°F.
Add your cleaned chicken legs into a large bowl. Drizzle the avocado oil all over the chicken. Use tongs or gloved hands to rub the oil into each drumstick.
Now sprinkle in all of your seasonings including the: Cajun seasoning, lemon pepper seasoned salt (if using it), garlic powder, onion powder, paprika, and black pepper.
Mix the seasonings in with the chicken so that each piece is fully covered.
Place your chicken into the air fryer in one single layer. Cook for 12 minutes, then flip it over and cook for an additional 8 minutes.
The chicken legs should be golden brown and crispy. Serve right away.
