Instructions

  1. Step 1: Preheat oven to 400°F. Carefully create a pocket in each of the 4 boneless skin-on chicken thighs and stuff each pocket with 1 oz sliced mozzarella cheese.
  2. Step 2: Season the stuffed chicken thighs evenly with 1 1/2 tsp salt, 1 tsp black pepper, and 1/2 tsp dried oregano.
  3. Step 3: Heat 2 tbsp olive oil in a large oven-safe skillet over medium-high heat. Add chicken thighs skin-side down and sear for 5 minutes until skin is golden and crispy.
  4. Step 4: Flip chicken thighs and transfer skillet to the preheated oven. Bake for 15-20 minutes until chicken is cooked through and cheese is melted.
  5. Step 5: While chicken bakes, melt 3 tbsp unsalted butter in a saucepan over medium heat. Add 2 minced garlic cloves and cook for 1 minute until fragrant.
  6. Step 6: Add 3 cups roughly chopped fresh spinach to the butter and garlic, cooking until wilted, about 3 minutes.
  7. Step 7: Pour in 1/2 cup heavy cream and simmer gently for 5 minutes until sauce thickens and coats the back of a spoon.
  8. Step 8: Serve the cheese-stuffed chicken thighs topped with warm spinach cream sauce.
