CHICKEN BREASTS WITH MUSHROOM AND ONION DIJON SAUCE
In our kitchen, a good-quality Dijon mustard is one of those must-have, staple ingredients that we always have on hand! We add it to so many recipes – vinaigrettes and dressings, and it’s a terrific addition to my husband Jack’s famous potato salad!
But we also love Dijon mustard when it’s been turned into a zesty, creamy sauce – and it plays a starring role in this recipe for Chicken Breasts with Mushroom and Onion Dijon Sauce.
This delicious recipe can best be described as sophisticated comfort food! Tender boneless chicken breasts are sautéed with sliced mushrooms and onions, then smothered in a rich, creamy sauce that has been flavored with a mix of traditional Dijon as well as whole-grain Dijon mustard, plus rosemary and other herbs and spices.
If you have large 12-ounce chicken breasts as we did for this recipe, butterfly them, then cut in half to get two portions, and repeat for the second large breast.

INGREDIENTS
  • 4 boneless skinless chicken breasts about 6 ounces each (1 ½ pounds)
  • ¼ cup flour
  • ½ teaspoon salt
  • ¼ teaspoon freshly ground black pepper
  • 4 tablespoons extra virgin olive oil
  • 4 cups sliced button mushrooms
  • 1 cup sliced red onion
  • 2 tablespoons fresh chopped rosemary
  • 1 tablespoons whole grain mustard
  • 2 tablespoons Dijon mustard
  • ½ cup white wine
  • 2 tablespoons fresh parsley chopped
  • ¼ cup chicken stock
  • ¼ cup heavy cream
  • 2 tablespoons butter

INSTRUCTIONS
  1. In a medium bowl, place flour, salt and pepper and mix. Dredge chicken in four, shake excess and set aside.
  2. In a large skillet heat oil over medium high heat until hot. Add chicken breasts and brown 3-4 minutes per side. If all four pieces will not fit, cook in two batches. Remove chicken to a platter and set aside.
  3. Heat pan back up to high and add mushrooms and cook for about three minutes until just starting to brown. Reduce to medium high and add onions and rosemary. Cook for two to three minutes. The mushrooms will give up some liquid when the onions are added. Add both mustards, and wine and scrape up bottom. Add parsley, stock, cream and butter and mix to combine. Add chicken back in and cover with sauce. Reduce heat to a simmer and cook just until the chicken is cooked through (depending on size). Serve with sauce over each portion.
