01 - Season the chicken breasts with salt, pepper, and paprika on both sides.
02 - In a large skillet, heat olive oil over medium-high heat. Sear the chicken for 3–4 minutes per side until golden. Remove from the skillet and set aside.
03 - Reduce heat to medium. Add butter to the same skillet. Sauté onion and mushrooms for 3–4 minutes until soft. Add garlic and cook for 30 seconds.
04 - Stir in flour and cook for 1 minute. Gradually whisk in chicken broth, milk, and heavy cream.
05 - Add thyme, parsley, salt, and pepper. Simmer for 2–3 minutes, stirring often, until slightly thickened. Stir in Parmesan.
06 - Return chicken to the skillet, nestling it into the sauce. Cover and cook on low heat for 15–20 minutes, until chicken is cooked through (internal temperature: 165°F).
07 - Rinse rice under cold water until water runs clear. In a saucepan, bring water or broth and salt to a boil. Add rice, cover, reduce heat to low, and simmer for 15–18 minutes until tender. Remove from heat and let sit, covered, for 5 minutes. Fluff with a fork.
08 - To serve, place a portion of rice on each plate, top with chicken breast, and spoon creamy sauce over everything.
