Chicken Dijonnaise is a classic French dish made with tender chicken breasts cooked in a creamy Dijon mustard sauce. The chicken is first seared to perfection, then simmered in a flavorful sauce made with Dijon mustard, white wine, and chicken broth. The result is a rich and tangy dish that is perfect for a special dinner or entertaining guests. Serve the Chicken Dijonnaise with mashed potatoes or rice and a side of steamed vegetables for a complete and delicious meal.
