Cook the Rice:
In a saucepan, bring 2 cups of water (or broth) and 1 tbsp butter to a boil.
Stir in the rice and a pinch of salt.
Cover, reduce heat to low, and simmer for 15–18 minutes, or until water is absorbed.
Fluff with a fork and set aside.
Season and Sear the Chicken:
Season chicken on all sides with salt, pepper, garlic powder, onion powder, and paprika.
Heat olive oil or butter in a skillet over medium-high heat.
Sear chicken skin-side down for 4–5 minutes until browned, flip and cook another 3–4 minutes. Remove and set aside.
Make the Creamy Gravy:
In the same skillet, sauté onions (and mushrooms if using) until soft—about 3–5 minutes.
Add garlic and cook another 30 seconds.
Sprinkle in the flour and stir for 1 minute.
Slowly whisk in the chicken broth, then the heavy cream.
Add thyme, red pepper flakes (if using), and season with salt and pepper.
Simmer until slightly thickened—about 5–7 minutes.
Smother the Chicken:
Return the chicken to the skillet, reduce heat to low, and spoon sauce over the chicken.
Cover and simmer for 15–20 minutes, or until chicken is cooked through and tender.
Serve:
Spoon cooked rice onto plates and top with smothered chicken and plenty of that creamy gravy.
