01 - Preheat the oven to 425°F.
02 - In a large bowl, whisk together olive oil, minced garlic, lemon zest, lemon juice, oregano, thyme, smoked paprika, salt, and black pepper.
03 - Add chicken thighs to the bowl and toss to coat thoroughly. Set aside to marinate.
04 - Spread halved potatoes and sliced onion in a large roasting pan or rimmed baking sheet. Drizzle with olive oil and season with salt and pepper.
05 - Place marinated chicken thighs skin side up on top of the potatoes and onions. Pour any remaining marinade over everything.
06 - Roast in the oven for 40 to 45 minutes until chicken skin is golden, the meat reaches an internal temperature of 165°F, and potatoes are tender.
07 - For extra crispy skin, broil for the last 2 to 3 minutes, monitoring carefully to prevent burning.
08 - Let rest for 5 minutes. Garnish with chopped parsley and serve with lemon wedges.
