Instructions

  1. Step 1: Pat 2 boneless skinless chicken breasts dry and season with 1 tsp salt and 1/2 tsp black pepper on both sides.
  2. Step 2: Heat 2 tbsp olive oil in a large skillet over medium-high heat until shimmering. Add chicken breasts and cook for 6-7 minutes per side until golden brown and internal temperature reaches 165°F. Remove chicken and keep warm.
  3. Step 3: Reduce heat to medium, add 1 tbsp unsalted butter, 1 finely chopped shallot and 1 minced garlic clove. Sauté for 2 minutes until softened and fragrant.
  4. Step 4: Pour in 1/4 cup dry white wine, scraping up browned bits, and simmer for 3 minutes until reduced by half.
  5. Step 5: Stir in 1/2 cup heavy cream and 2 tbsp Dijon mustard, cooking for 2-3 minutes until sauce thickens and coats the back of a spoon.
  6. Step 6: In a separate pan, heat 1 tbsp olive oil over medium heat. Add 4 cups baby spinach and sauté for 2 minutes until wilted. Season with 1 tsp lemon juice and a pinch of salt.
  7. Step 7: Plate chicken breasts and spoon mustard cream sauce over top with sautéed spinach on the side.
