01 - Preheat oven to 425°F (220°C). Line a baking sheet with parchment paper or aluminum foil and set aside.
02 - Pat the chicken thighs thoroughly dry with paper towels and place them in a large mixing bowl. Drizzle with olive oil and toss until all pieces are evenly coated.
03 - In a small bowl, whisk together the kosher salt, black pepper, paprika, garlic powder, onion powder, dried thyme, and dried oregano until well combined. Sprinkle the seasoning blend over the chicken thighs, turning each piece to ensure full, even coverage on all sides.
04 - Place the seasoned chicken thighs on the prepared baking sheet, skin side up, spacing them at least 1 inch apart to allow proper air circulation for crisping.
05 - Bake on the center rack for 35–40 minutes, until the skin is deeply golden and crisp and an instant-read meat thermometer inserted into the thickest portion of the thigh registers 165°F (74°C).
06 - Remove the baking sheet from the oven and let the chicken rest for 5 minutes to allow juices to redistribute. Garnish with chopped fresh parsley and serve with lemon wedges alongside.
