Ingredients

Instructions

  1. Step 1: Pat dry 2 boneless skinless chicken breasts (6 oz each), season with 1 tsp salt and 1/2 tsp black pepper evenly. Heat 2 tbsp unsalted butter and 1 tbsp olive oil in a large skillet over medium-high heat until shimmering.
  2. Step 2: Place chicken breasts in the skillet and sear for 5-6 minutes on each side until golden brown and cooked through (internal temperature 165°F). Remove chicken and keep warm.
  3. Step 3: Reduce heat to medium, add 2 tbsp finely minced shallots to the skillet and sauté for 2 minutes until translucent and fragrant.
  4. Step 4: Pour in 1/3 cup dry white wine and simmer for 3 minutes until reduced by half and slightly syrupy.
  5. Step 5: Whisk in 2 tbsp Dijon mustard and 1/2 cup heavy cream, stirring continuously over low heat until the sauce thickens and coats the back of a spoon, about 4 minutes.
  6. Step 6: Return chicken breasts to the skillet, spoon sauce over them, and cook for an additional 2 minutes to meld flavors.
  7. Step 7: Sprinkle 1 tbsp chopped fresh parsley on top before serving warm.
