Season both sides of the chicken breasts with salt, pepper, garlic powder, paprika, and flour.
In a large skillet or pan, heat olive oil and butter over medium-high heat. Add the chicken breasts and cook for about 4-5 minutes on each side until they turn golden brown. Remove the chicken from the skillet and set it aside.
Stir in the rice, add the chicken broth and then add the green beans to one side. Bring to a low simmer.
Place the browned chicken breasts on top of the rice mixture. Cover the skillet with a lid and reduce the heat to low. Let it simmer for 15-20 minutes, or until the rice is cooked and the chicken is fully done.
Once the rice is cooked and the chicken is tender, remove the skillet from heat. Allow it to rest for a few minutes before serving.
Season with salt and pepper. Enjoy your hearty and comforting one-pot meal! ?
