Start by marinating the chicken. In a bowl, combine sweet chili sauce, minced garlic, soy sauce, honey, and grated ginger. Mix well.
Place the chicken breasts in a large resealable bag or dish, and pour the marinade over the chicken, ensuring it is well-coated. Seal the bag or cover the dish and refrigerate for at least 30 minutes (or up to 2 hours for more flavor).
Preheat your oven to 400°F (200°C).
In a large oven-safe skillet, heat olive oil over medium-high heat. Remove the chicken from the marinade, allowing excess marinade to drip off, and season with salt and pepper.
Once the oil is hot, add the chicken breasts to the skillet and sear for about 3-4 minutes on each side until they develop a golden-brown crust.
Pour the remaining marinade over the chicken in the skillet.
Transfer the skillet to the preheated oven and bake for 20-25 minutes, or until the internal temperature of the chicken reaches 165°F (75°C).
Once done, remove the skillet from the oven and let the chicken rest for about 5 minutes before slicing.
Serve the chicken garnished with sesame seeds and chopped green onions. Drizzle with any remaining sauce from the skillet.
Notes
For more flavor, marinate the chicken for up to 2 hours.
