Preheat the oven to 425°F. Season chicken thighs evenly with smoked paprika, garlic powder, onion powder, black pepper, salt, and cayenne if using.
Place the chicken thighs skin side up on a baking sheet and roast uncovered until skin is crisp and chicken is cooked through, about 35 to 40 minutes.
While chicken roasts, bring chicken broth to a boil in a pot. Add rice, butter, smashed garlic, and thyme or bay leaf, reduce heat to low, cover, and simmer until rice is tender.
Remove garlic and herb from rice, fluff with fork, and let it absorb any remaining juices from the pot.
In a skillet, melt butter and sauté minced garlic briefly until fragrant. Add green beans and a splash of chicken broth.
Cook green beans until tender but still crisp, about 5 to 7 minutes. Season with black pepper and a touch of lemon juice or vinegar.
Serve the crispy chicken thighs over the buttery rice alongside the green beans.
Optionally drizzle pan gravy, hot honey, or pepper jelly over the chicken and garnish with fresh parsley. Serve with cornbread or biscuits if desired.
