01 - Preheat oven to 425°F. Pat the chicken thighs thoroughly dry with paper towels to ensure crispy skin.
02 - In a large bowl, whisk together the olive oil, lemon zest, lemon juice, black pepper, kosher salt, minced garlic, thyme, and oregano until well combined.
03 - Add the chicken thighs to the marinade, turning each piece to coat thoroughly. Allow to marinate for at least 10 minutes at room temperature, or cover and refrigerate up to 2 hours for more pronounced flavor.
04 - Place the chicken thighs skin-side up on a rimmed baking sheet or in a large ovenproof skillet. Spoon any remaining marinade over the top of each piece.
05 - Roast in the preheated oven for 30 to 35 minutes, until the skin is deeply golden and crisp and an instant-read thermometer inserted into the thickest part of the thigh registers 165°F.
06 - Remove from the oven and let the chicken rest for 5 minutes before serving. Garnish with chopped fresh parsley and lemon slices.
