A comforting yet refined dish featuring tender chicken simmered in a creamy Dijon mustard sauce with earthy mushrooms, served over a silky cauliflower purée. This elegant meal feels indulgent while remaining light and balanced.

Ingredients

  • For the chicken:
  • 4 boneless, skinless chicken breasts
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • 2 tablespoons olive oil
  • 8 ounces mushrooms, sliced
  • 3 cloves garlic, minced
  • 1 cup chicken broth
  • ½ cup heavy cream
  • 2 tablespoons Dijon mustard
  • 1 teaspoon fresh thyme leaves
  • For the cauliflower purée:
  • 1 large head cauliflower, cut into florets
  • 2 tablespoons butter
  • ¼ cup milk or cream
  • ½ teaspoon salt
  • ¼ teaspoon black pepper

Instructions

  1. Steam or boil cauliflower florets for 12–15 minutes until very tender.
  2. Season chicken breasts with salt and pepper.
  3. Heat olive oil in a large skillet over medium heat and sear chicken on both sides until golden. Remove and set aside.
  4. In the same skillet, sauté mushrooms until browned and tender.
  5. Add garlic and cook for 30 seconds until fragrant.
  6. Pour in chicken broth and simmer, scraping up browned bits from the pan.
  7. Stir in heavy cream, Dijon mustard, and thyme.
  8. Return chicken to the skillet and simmer gently for 8–10 minutes until fully cooked and sauce thickens slightly.
  9. Drain cauliflower and blend with butter, milk or cream, salt, and pepper until smooth.
  10. Serve chicken and mushrooms over cauliflower purée, spooning extra sauce on top.

Notes

  • Chicken thighs can be substituted for extra richness.
  • Add whole-grain mustard for stronger flavor and texture.
  • Replace heavy cream with half-and-half for a lighter option.
  • Add fresh spinach to the sauce during the final minutes for extra greens.
  • Deglaze the pan with a splash of dry white wine for added depth.
  • Store in the refrigerator for up to 3 days and reheat gently with a splash of broth or cream.
