In a large mixing bowl, combine the olive oil, smoked paprika, oregano, onion powder, minced garlic, lemon zest, salt, and pepper. Mix well to create a marinade.
Add the chicken thighs to the marinade, ensuring they are well coated. Let them marinate for about 15 minutes while you prepare the vegetables.
In a large oven-safe skillet or pan, arrange the marinated chicken thighs in a single layer. Surround them with the trimmed green beans and halved cherry tomatoes.
Squeeze the lemon juice over the entire dish for extra flavor.
Place the skillet in the preheated oven and roast for about 25-30 minutes, or until the chicken is cooked through (internal temperature of 165°F/74°C) and the green beans are tender yet vibrant.
For a crispy finish, broil the dish for an additional 3-5 minutes after roasting, keeping a close eye to prevent burning.
Once done, remove from the oven and let rest for a few minutes. Garnish with fresh basil leaves if desired.
Notes
Serve directly from the pan for a rustic look, or transfer to a serving platter with extra lemon wedges and basil.
