Preheat your oven to 425°F (220°C).
Pat the chicken thighs dry with paper towels to ensure crispy skin.
In a large bowl, combine olive oil, garlic powder, onion powder, smoked paprika, dried thyme, salt, and black pepper.
Add the chicken thighs to the bowl and toss them until they are evenly coated with the seasoning mixture.
Place the chicken thighs skin-side up on a baking sheet lined with parchment paper or aluminum foil.
Bake in the preheated oven for 35-40 minutes, or until the internal temperature reaches 165°F (74°C) and the skin is crispy.
For extra crispiness, broil the chicken for an additional 2-3 minutes at the end of baking.
Let the chicken rest for 5 minutes before serving.
