Ingredients
  

Chicken breasts
  • 4 boneless skinless chicken breasts
  • 0.5 tsp salt To taste (amount placeholder for consistency).
  • 0.5 tsp pepper To taste (amount placeholder for consistency).
  • 0.5 tsp garlic powder To taste (amount placeholder for consistency).
  • 0.5 tsp dried thyme To taste (amount placeholder for consistency).
Sauté base and sear
  • 2 tbsp olive oil
  • 2 tbsp butter
  • 2 shallots Finely minced.
  • 8 oz cremini mushrooms Sliced.
  • 3 garlic Minced.
Whiskey cream sauce
  • 1.33 cup Irish whiskey (Jameson) 1/3 cup total; listed as 1.33 cup is incorrect, adjust? (See pro tip to measure 1/3 cup).
  • 1 cup heavy cream
  • 0.5 cup chicken broth
  • 1 tbsp Dijon mustard
  • 1 tsp fresh thyme leaves
  • fresh thyme sprigs For garnish.

Equipment

  • 1 cast iron skillet

Method
 

Season and sear the chicken
  1. Season boneless skinless chicken breasts with salt, pepper, garlic powder, and dried thyme. Heat olive oil in a large cast iron skillet over medium-high heat, sear chicken for 5-6 minutes per side until golden and cooked through to 165°F (use a thermometer), then remove to a plate.
Cook mushrooms and build the aromatics
  1. Melt butter in the same skillet over the stove. Cook shallots and cremini mushrooms for 5-6 minutes until golden, then add garlic and cook 1 minute while fragrant.
Deglaze with whiskey and simmer the sauce
  1. Remove the skillet from heat and carefully pour in Irish whiskey (Jameson). Return to medium heat and let it bubble for 1-2 minutes to cook off the alcohol, stirring as needed.
  2. Stir in heavy cream, chicken broth, Dijon mustard, and fresh thyme leaves. Simmer for 5-6 minutes until the sauce thickens and coats the back of a spoon.
Finish and garnish
  1. Return the chicken breasts to the skillet. Spoon whiskey cream sauce over each breast to coat the top and edges, then let the sauce re-warm for 1 minute.
  2. Garnish with fresh thyme sprigs for a bright, herb-flecked finish. Serve immediately while the sauce is thick and amber.

Notes

Pro tip: Keep the whiskey pour controlled—remove from heat first so the alcohol won’t flare, then simmer until bubbling calms. Refrigerate leftovers in an airtight container up to 3 days; reheat gently in a skillet over low heat until warmed through. Freeze yes—freeze chicken and sauce separately if possible, thaw in the fridge, then reheat slowly. Dietary swap: For a lighter option, use half-and-half instead of heavy cream (the sauce may be slightly thinner).
