Tender chicken breasts are lightly floured and pan-seared in olive oil until golden, then simmered in a creamy Dijon honey mustard sauce enriched with chicken broth and half-and-half. Sweet onions and earthy mushrooms add depth and balance, while a touch of salt and pepper rounds out the flavors. The result is a comforting, slightly tangy dish with a velvety sauce that clings beautifully to the chicken. Perfect served over rice, pasta, or with crusty bread to soak up every drop of the rich, savory-sweet sauce.
