Cook Chicken:Season chicken with garlic powder, onion powder, paprika, salt, and pepper. Heat olive oil in a skillet over medium heat. Sear chicken 5–6 minutes per side until golden brown and fully cooked. Remove and set aside.
Sauté Aromatics:In the same skillet, sauté diced onion for 2–3 minutes until soft. Add minced garlic and cook for 1 minute.
Make Creamy Sauce:Sprinkle flour over the onions and stir for 1 minute. Slowly whisk in chicken broth, then add cream. Simmer until thickened, about 5 minutes.
Smother the Chicken:Return chicken to the skillet. Spoon sauce over it, cover, and simmer on low heat for 5–10 minutes. Add cheese (optional) and stir gently.
Serve:Plate warm rice and top with smothered chicken and sauce. Garnish with chopped parsley if desired.
