Heat your oven to 400 degrees Fahrenheit.
Rinse the chicken thighs in a bowl of water and pat them completely dry.
In a small bowl, stir together the smoked paprika, garlic powder, salt, black pepper, thyme, and parsley.
Place the chicken, halved potatoes, and green beans in a large mixing bowl; drizzle with olive oil and sprinkle the seasoning blend on top.
Use your hands to toss everything thoroughly until all pieces are coated evenly.
Arrange the potatoes and green beans in a single layer on a baking sheet.
Set a wire rack over the vegetables and place the chicken thighs on the rack, leaving about an inch of space between each.
Cook in the preheated oven for 45 to 48 minutes or until the chicken reaches an internal temperature of 165 degrees Fahrenheit.
After baking, transfer the chicken to the baking sheet with the vegetables and brush some of the pan juices over everything.
Serve warm and enjoy your effortless, one pan meal!
