Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F. Using a sharp knife, cut a horizontal slit in each of the 4 boneless skinless chicken breasts to create a pocket about 3 inches long.
  2. Step 2: In a medium bowl, combine 1 cup thawed and squeezed dry frozen chopped spinach, 1/2 cup crumbled feta cheese, and 2 minced garlic cloves. Mix well.
  3. Step 3: Stuff each chicken breast pocket evenly with the spinach and feta mixture, securing with toothpicks if needed.
  4. Step 4: Rub the outside of each chicken breast with 2 tablespoons olive oil, then season all sides with 1 teaspoon salt, 1/2 teaspoon black pepper, and 1 teaspoon dried oregano.
  5. Step 5: Place the stuffed chicken breasts in a baking dish and bake for 25-30 minutes until the internal temperature reaches 165°F and the chicken is cooked through.
  6. Step 6: Let rest for 5 minutes before slicing and serving.
