Poulet à La Moutarde, also known as Chicken with Mustard, is a classic French dish that features tender chicken cooked in a creamy mustard sauce. The chicken is first seared to lock in the juices and then simmered in a flavorful sauce made with mustard, cream, white wine, and herbs. The result is a rich and indulgent dish with a perfect balance of flavors. Serve this delicious chicken with mashed potatoes or crusty bread for a complete meal.
