Chicken Supreme is a classic French dish that features tender chicken breasts cooked in a creamy mushroom sauce. The chicken is first seared to lock in the juices, then simmered in a flavorful combination of mushrooms, onions, garlic, and white wine. The sauce is made with heavy cream and chicken broth, giving it a rich and velvety texture. This elegant and delicious dish is perfect for a special occasion or a fancy dinner party.
