Preheat oven to 375°F (190°C).
Season the chicken thighs with garlic powder, onion powder, paprika, salt, and pepper.
In a large oven-safe skillet or Dutch oven, heat olive oil over medium heat.
Sear chicken thighs skin-side down for about 4-5 minutes until browned. Flip and cook 2 more minutes. Remove and set aside.
Add butter and chopped onion to the skillet and sauté until translucent.
Stir in the rice, cream of chicken soup, and chicken broth. Mix well.
Nestle the chicken thighs into the rice mixture, skin-side up.
Cover with foil and bake for 35 minutes. Remove foil and bake an additional 10-15 minutes until the chicken is fully cooked and rice is tender.
Serve hot, garnished with fresh herbs if desired.
