Cook the rice according to package instructions. Fluff with a fork and keep warm.
Heat olive oil in a large skillet over medium-high heat.
Season the chicken pieces with garlic powder, onion powder, smoked paprika, salt, and black pepper.
Add the chicken to the hot skillet and sear for 2–3 minutes.
Stir and continue cooking for another 3–4 minutes, or until the chicken reaches an internal temperature of 165°F (74°C).
Remove the chicken from the skillet and set aside.
Reduce the heat to medium and add the butter.
Once melted, stir in the minced garlic and cook for about 30 seconds until fragrant.
Add the flour and whisk continuously for about 1 minute to create a smooth roux.
Slowly whisk in the chicken broth followed by the heavy cream.
Bring the mixture to a gentle simmer and cook for 1–2 minutes until slightly thickened.
Stir in the salt, pepper, nutmeg, and Parmesan cheese until smooth.
Return the chicken to the skillet and stir to coat completely in the creamy sauce.
Simmer for 2–3 minutes until everything is heated through.
Serve the Creamy Smothered Chicken and Rice by spooning the chicken and sauce over the cooked rice.
Garnish with freshly chopped parsley and serve immediately.
