Instructions

Step 1: Pat dry 2 boneless skinless chicken breasts and season both sides with 1 tsp salt and 1/2 tsp black pepper.
Step 2: Heat 2 tbsp olive oil in a large skillet over medium-high heat until shimmering. Add the chicken breasts and sear for 5-6 minutes on each side until golden brown and internal temperature reaches 165°F. Remove chicken and keep warm.
Step 3: Reduce heat to medium and add 1 tbsp unsalted butter and 2 minced garlic cloves to the same skillet. Sauté for 1 minute until fragrant.
Step 4: Stir in 2 tbsp Dijon mustard and 1/2 cup heavy cream, simmering gently for 3-4 minutes until the sauce thickens and coats the back of a spoon.
Step 5: In a separate pan, heat 1 tbsp olive oil over medium heat. Add 4 cups fresh spinach and 1 tsp lemon juice. Sauté for 2-3 minutes until wilted but still bright green.
Step 6: Serve the chicken breasts topped with mustard cream sauce alongside the sautéed spinach.
