Instructions

1. Step 1: Preheat oven to 375°F. Using a sharp knife, cut a horizontal pocket into each of the 4 chicken breasts without cutting all the way through.
2. Step 2: In a medium skillet over medium heat, add 1 tbsp olive oil and sauté 2 cups fresh spinach for 2-3 minutes until wilted. Remove from heat and let cool slightly.
3. Step 3: In a bowl, mix the sautéed spinach, 4 oz softened cream cheese, and 1/2 cup shredded mozzarella cheese until combined.
4. Step 4: Stuff each chicken breast pocket evenly with the cheese and spinach mixture. Secure with toothpicks if needed.
5. Step 5: Season the stuffed chicken breasts with 1 tsp salt, 1/2 tsp black pepper, and 1/2 tsp dried oregano.
6. Step 6: Heat remaining 1 tbsp olive oil and 2 tbsp unsalted butter in an oven-safe skillet over medium-high heat. Add chicken breasts and sear for 3-4 minutes per side until golden brown.
7. Step 7: Transfer the skillet to the oven and bake for 15-18 minutes until the chicken is cooked through (internal temperature 165°F).
8. Step 8: Meanwhile, melt the remaining 2 tbsp butter in a small pan over low heat, add 4 minced garlic cloves, and cook for 2 minutes until fragrant. Drizzle this garlic butter sauce over the finished chicken before serving.
