In a medium mixing bowl, combine the chopped spinach, finely chopped sun-dried tomatoes, crumbled feta cheese, softened cream cheese, minced garlic, dried oregano, salt, and black pepper. Mix together until all ingredients are well incorporated into a creamy filling.
Take each chicken breast and carefully slice a pocket into the thickest part, ensuring not to cut all the way through so that the filling stays inside.
Generously stuff each chicken breast with the prepared filling mixture, pressing gently to pack it in without overfilling.
In a large oven-safe skillet, heat the olive oil over medium-high heat. Once shimmering, gently add the stuffed chicken breasts to the pan. Sear each side for about 3-4 minutes until they turn a beautiful golden brown.
Pour the chicken broth around the chicken in the skillet; this will keep the chicken moist during roasting.
Carefully transfer the skillet to your preheated oven. Bake for 20-25 minutes or until the chicken is thoroughly cooked and reaches an internal temperature of 165°F (75°C).
After baking, remove the skillet from the oven and let the chicken rest for 5 minutes. Garnish your gourmet stuffed chicken with fresh basil leaves before serving.
Notes
Let the chicken rest after baking for juicier meat.
