Equipment

Ingredients

  • 1 pound boneless skinless chicken breasts sliced in half horizontally
  • 1 tablespoon olive oil
  • 1 teaspoon paprika
  • 1 teaspoon garlic powder
  • Salt and black pepper to taste
  • 4 garlic cloves minced
  • ¼ cup sweet Marsala wine
  • ¼ cup low-sodium chicken broth or additional Marsala wine
  • 2 cups sliced mushrooms
  • ¼ cup heavy cream
  • 3 tablespoons cornstarch
  • 2–3 tablespoons cold water for slurry
  • Fresh parsley or thyme for garnish

Instructions

    1 pound boneless skinless chicken breasts, 1 teaspoon paprika, 1 teaspoon garlic powder, Salt and black pepper
  • Heat olive oil in a skillet over medium-high heat and sear the chicken 2–3 minutes per side until lightly browned.
    1 tablespoon olive oil
  • Transfer the chicken to the slow cooker and add mushrooms, minced garlic, Marsala wine, and chicken broth.
    4 garlic cloves, ¼ cup sweet Marsala wine, ¼ cup low-sodium chicken broth, 2 cups sliced mushrooms
  • Cover and cook on LOW for 2 hours or until the chicken is fully cooked and tender.
  • Turn the slow cooker to HIGH.
  • In a small bowl, whisk cornstarch with cold water to create a smooth slurry.
    3 tablespoons cornstarch, 2–3 tablespoons cold water
  • Stir the slurry into the slow cooker and cook for 10 minutes until the sauce thickens.
  • Remove chicken and set aside. Stir in heavy cream and mix well.
    ¼ cup heavy cream
  • Serve the chicken with the sauce and garnish with fresh parsley or thyme.

Notes

  • Slice each breast in half horizontally so it cooks evenly and the thick end does not stay underdone.
  • Sear the chicken 2 to 3 minutes per side before it goes in; the browning adds flavor that the slow cooker cannot.
  • Use sweet Marsala for a slightly sweet, nutty sauce; dry Marsala works in a pinch, but skip cooking wine.
  • Whisk the cornstarch with cold water before adding it, or it clumps in the hot liquid.
  • Lift the chicken out and stir the cream in off the direct heat so it does not curdle.
  • Cool the dish completely in the fridge before freezing so the sauce texture stays smoother after thawing.
  • Reheat leftovers gently on the stovetop over low heat so the cream sauce stays smooth.
