Preheat your oven to 400°F (200°C). Line a baking sheet with foil or parchment paper for easier cleanup.

Pat the chicken legs dry with paper towels. This helps the seasoning stick better and promotes crispy skin.

In a large bowl, toss the chicken legs with olive oil until evenly coated.

In a small bowl, combine garlic powder, onion powder, paprika, salt, and pepper. Sprinkle this seasoning mixture over the chicken legs, making sure they're evenly coated on all sides.

Place the seasoned chicken legs on the prepared baking sheet, leaving space between each piece. If using a wire rack, place it on the baking sheet and arrange the chicken on top for crispier results.

Bake in the preheated oven for 25 minutes.

Remove the chicken from the oven and brush generously with barbecue sauce, turning to coat all sides.

Return to the oven and bake for an additional 10-15 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the sauce has caramelized.

For extra saucy chicken, brush with additional barbecue sauce during the final 5 minutes of cooking.

Allow the chicken legs to rest for 5 minutes before serving to help the juices redistribute.
