Preheat the oven to 400°F (200°C) and prepare a large baking dish.

In a bowl, coat the chicken thighs with olive oil, smoked paprika, garlic powder, salt, and pepper.

Toss the halved potatoes and sliced bell peppers in olive oil, salt, and pepper until well-coated.

Arrange the seasoned chicken in the baking dish and surround it with the potatoes and peppers.

Roast for 45-50 minutes or until the chicken reaches an internal temperature of 165°F (75°C) and vegetables are tender.

Let rest for 5 minutes before serving.
