Preheat your oven to 400°F (200°C).

Rinse the chicken thighs under cold water and pat them dry with paper towels.

In a mixing bowl, combine ranch dressing, garlic powder, onion powder, paprika, salt, and pepper.

Brush the ranch mixture generously over each chicken thigh.

Place the coated chicken thighs in an oven-safe baking dish, skin side up.

Bake in the preheated oven for 30 minutes or until the internal temperature reaches 165°F (75°C).

If desired, switch the oven to broil for the last 3-5 minutes for extra crispiness.

Remove the chicken from the oven and let it rest for 5 minutes before serving.
