  • 2 shallots finely minced
  • 8 oz cremini mushrooms sliced
  • 3 garlic cloves, minced
Sauce

  • 1 cup heavy cream
  • 0.5 cup chicken broth
  • 1 tbsp Dijon mustard
  • 1 tsp fresh thyme leaves
  • 0.5 fresh thyme sprigs for garnish

Equipment

  • 1 Cast iron skillet

Method
 

Season and sear the chicken
  1. Pat chicken breasts dry and season all over with salt, pepper, garlic powder, and dried thyme to taste.
  2. Heat olive oil in a large skillet over medium-high heat until shimmering, then add chicken and sear for 5-6 minutes per side until golden and cooked through to 165°F; remove to a plate.
Cook the mushroom shallot mixture
  1. Melt butter in the same pan, then add shallots and cremini mushrooms and cook for 5-6 minutes until golden.
  2. Add minced garlic and cook for 1 minute, stirring to prevent burning.
Build the whiskey cream sauce
  1. Remove the pan from the heat and carefully pour in Irish whiskey, then return to medium heat.
  2. Let the alcohol cook off for 1-2 minutes until the bubbling reduces.
  3. Stir in heavy cream, chicken broth, Dijon mustard, and fresh thyme leaves, then simmer for 5-6 minutes until the sauce thickens.
Finish and garnish
  1. Return chicken breasts to the pan and spoon whiskey cream sauce over each breast.
  2. Garnish with fresh thyme sprigs and serve while hot.

Notes

Pro tip: sear the chicken without moving it to develop a deep golden crust, then deglaze carefully with whiskey while the pan is off-heat to reduce splatter. Store leftovers covered in the refrigerator up to 3 days; reheat gently to avoid breaking the cream. Freezing is not recommended because the cream sauce can separate. For a lighter option, use half-and-half instead of heavy cream, expecting a slightly thinner sauce.
