Heat the olive oil in a large skillet over medium-high heat.
Season the chicken breasts with salt, pepper, garlic powder, onion powder, and paprika.
Sear the chicken in the heated skillet for 5-6 minutes on each side until golden brown.
Remove the chicken from the skillet and set aside.
Add the chicken broth to the skillet, scraping the bottom to release any stuck bits.
Stir in the heavy cream and bring to a gentle simmer.
Add the chicken back to the skillet, cover, and simmer for 10-15 minutes.
Stir in the cooked white rice and cheese (if using), gently mixing until combined.
Taste and adjust seasoning before serving, adding more salt or pepper if necessary.
Serve hot, garnished with fresh herbs if desired.
