Method
 

Season and sear the chicken
  1. Season the chicken breasts with salt, pepper, garlic powder, and dried thyme. Heat the olive oil in a large skillet over medium-high heat, then sear the chicken 5-6 minutes per side until golden and cooked through to 165°F, and remove to a plate.
Cook shallots and mushrooms
  1. Melt the butter in the same pan. Cook the shallots and mushrooms 5-6 minutes until golden, then add the garlic and cook 1 minute.
Build the whiskey cream sauce
  1. Remove the pan from the heat and carefully pour in the Irish whiskey. Return to medium heat and let the alcohol cook off for 1-2 minutes.
  2. Stir in the heavy cream, chicken broth, Dijon mustard, and fresh thyme leaves. Simmer 5-6 minutes until the sauce thickens.
Finish and garnish
  1. Return the chicken to the pan and spoon the whiskey cream sauce over each breast until coated. Garnish with fresh thyme sprigs right before serving.

Notes

Pro tip: Keep the skillet hot for the first sear so the chicken turns deep golden before it releases moisture. Refrigerate leftovers in an airtight container for up to 3 days; reheat gently to avoid thinning the cream sauce. Freezing is not recommended due to cream texture. Dietary swap: use gluten-free Dijon if needed and choose a gluten-free broth.
