Preheat your oven to 180°C (350°F) and gather all your ingredients.
Use a sharp knife to carefully slice a horizontal pocket into each chicken breast, making sure not to cut all the way through.
In a small bowl, combine the goat cheese, chopped sun-dried tomatoes, chopped basil, and garlic salt until well mixed—this creates your flavorful stuffing.
Stuff each chicken pocket generously with the cheese mixture, pressing gently to fill evenly.
Secure each stuffed pocket with toothpicks to prevent the filling from spilling out during cooking.
Heat the olive oil in a skillet over medium-high heat until it shimmers and begins to gently smoke.
Sear the chicken breasts for about 3-4 minutes per side until they develop a rich, golden-brown crust.
Transfer the skillet to the preheated oven and bake for 20-25 minutes, until the chicken reaches an internal temperature of 75°C (165°F).
Remove the skillet from the oven and let the chicken rest for 5 minutes—this helps keep the juices locked in.
Carefully remove the toothpicks and slice the chicken to reveal the gooey, flavorful stuffing inside.
Serve the stuffed chicken breasts hot, garnished with extra basil if desired. Enjoy the tender, juicy, and beautifully presented dish!
