Pat the chicken legs dry with paper towels to remove excess moisture. This helps achieve a crispy skin.

In a mixing bowl, combine olive oil, garlic powder, paprika, onion powder, salt, black pepper, dried thyme, and lemon juice. Mix well to create a marinade.

Add the chicken legs to the bowl and toss them in the marinade until they are evenly coated. Let them marinate for at least 15 minutes, or up to 2 hours in the refrigerator for deeper flavor.

Preheat your air fryer to 400°F (200°C) for about 5 minutes. Preheating ensures the chicken cooks evenly and gets crispy.

Place the marinated chicken legs in the air fryer basket in a single layer, ensuring they are not overcrowded. This allows hot air to circulate and cook the chicken evenly.

Cook the chicken legs at 400°F (200°C) for 25-30 minutes, flipping them halfway through the cooking time for even browning. Use a meat thermometer to check for doneness; the internal temperature should reach 165°F (74°C).

Once cooked, remove the chicken legs from the air fryer and let them rest for 5 minutes before serving. This helps the juices redistribute, making the chicken more tender.
