Ingredients

Instructions

  1. Step 1: Season 6 boneless, skin-on chicken thighs with 1 1/2 tsp salt and 1 tsp black pepper. Heat 2 tbsp olive oil in a large skillet over medium-high heat. Add chicken skin side down and cook for 6-7 minutes until the skin is golden and crisp, then flip and cook 5 minutes more until cooked through. Remove chicken and set aside.
  2. Step 2: Reduce heat to medium and melt 2 tbsp unsalted butter in the same skillet. Add 8 oz sliced cremini mushrooms and sauté for 5 minutes until browned and tender.
  3. Step 3: Add 4 minced garlic cloves and cook for 1 minute until fragrant. Stir in 5 cups fresh spinach leaves and cook until wilted, about 2 minutes.
  4. Step 4: Pour in 1 cup heavy cream and 1/2 cup grated Parmesan cheese, stirring until the sauce thickens and coats the mushrooms and spinach, about 3 minutes. Sprinkle 1 tsp dried thyme and adjust seasoning with salt and pepper.
  5. Step 5: Return chicken thighs to the pan and spoon sauce over them. Simmer for 2 minutes to meld flavors before serving.
