Preheat your oven to 425 degrees Fahrenheit (220 degrees Celsius).
Pat the chicken thighs completely dry using paper towels. This step is crucial for crispy skin.
In a small bowl, mix the salt, pepper, paprika, garlic powder, and thyme.
Rub the olive oil over the chicken thighs, coating the skin lightly.
Sprinkle the seasoning mix evenly over the chicken thighs, focusing on coating the skin surface.
Arrange the chicken thighs skin-side up on a wire rack placed over a baking sheet. This allows air to circulate for even crisping.
Bake for 35 to 45 minutes, or until the internal temperature reaches 175 degrees Fahrenheit (80 degrees Celsius) when checked with a meat thermometer in the thickest part of the thigh, avoiding the bone.
For extra crispness, switch the oven to the broiler setting for the last 1 to 3 minutes, watching closely to prevent burning.
Remove the chicken from the oven and let it rest on the rack for 5 minutes before serving.
Notes
For boneless, skinless thighs, reduce the baking time to 25 to 30 minutes at 400 degrees Fahrenheit (200 degrees Celsius).
To keep the meat juicy, do not overcook; check the temperature early.
If you prefer a simple flavor, use only salt and pepper.
