Instructions

  1. Step 1: Preheat oven to 375°F. In a bowl, mix 2 cups chopped fresh spinach, 4 oz softened cream cheese, and 1/2 cup shredded mozzarella until well combined.
  2. Step 2: Carefully loosen the skin of 6 boneless skin-on chicken thighs and spread the spinach-cheese mixture evenly under the skin. Season each thigh with 1 1/2 tsp salt and 1 tsp black pepper.
  3. Step 3: Heat 2 tbsp olive oil in an oven-safe skillet over medium-high heat. Add the chicken thighs skin-side down and sear for 5 minutes until the skin is golden and crispy.
  4. Step 4: Flip the chicken thighs over, add 3 tbsp butter and 3 minced garlic cloves to the skillet, spoon the melted garlic butter over the chicken, then transfer the skillet to the oven and bake for 15-18 minutes until the chicken reaches an internal temperature of 165°F.
  5. Step 5: Remove from oven and let rest for 5 minutes before serving, spooning any remaining garlic butter from the pan over the chicken.
