01 - Season chicken breasts on both sides with salt, pepper, and paprika, ensuring even coverage.
02 - Heat olive oil in a large skillet over medium-high heat. Sear chicken for 3–4 minutes per side until golden brown. Remove from skillet and set aside.
03 - Reduce heat to medium. Add butter to the skillet and sauté onion and mushrooms for 3–4 minutes until softened. Add garlic and cook for 30 seconds until fragrant.
04 - Stir in flour and cook for 1 minute to remove raw flour taste. Gradually whisk in chicken broth, milk, and heavy cream until smooth.
05 - Add thyme, parsley, salt, and pepper. Simmer for 2–3 minutes, stirring frequently, until slightly thickened. Stir in Parmesan until melted and incorporated.
06 - Return chicken to the skillet, nestling into sauce. Cover and cook over low heat for 15–20 minutes until chicken reaches 165°F internally.
07 - Rinse rice under cold water until clear. Bring water or broth and salt to a boil in a saucepan. Add rice, cover, reduce heat to low, and simmer for 15–18 minutes until tender. Remove from heat, covered, for 5 minutes. Fluff with fork.
08 - Place rice on plates, top with chicken breast, and spoon generous amount of creamy sauce over everything.
