01 - Preheat the oven to 425°F.
02 - In a large bowl, whisk together olive oil, minced garlic, lemon zest, lemon juice, dried oregano, dried thyme, smoked paprika, salt, and black pepper.
03 - Add chicken thighs to the marinade and toss to coat evenly. Set aside to marinate while preparing the potatoes.
04 - Spread halved potatoes and sliced onion on a large roasting pan. Drizzle with olive oil and season lightly with salt and pepper.
05 - Place marinated chicken thighs skin side up atop the potatoes and onions. Pour remaining marinade over all ingredients.
06 - Roast in the preheated oven for 40 to 45 minutes, or until the chicken skin is golden and crisp, internal temperature reaches 165°F, and potatoes are tender.
07 - For extra crispy skin, broil for 2 to 3 minutes, monitoring closely to prevent burning.
08 - Allow to rest for 5 minutes before garnishing with fresh parsley and serving with lemon wedges.
