Creating Sticky Sweet Chili Chicken Thighs can be a straightforward process if you follow these easy steps:

1. Prepare Marinade: In a bowl, mix together sweet chili sauce, soy sauce, honey, garlic, and ginger until well combined.
2. Marinate Chicken: Place the chicken thighs in a resealable bag or shallow dish. Pour the marinade over the chicken, ensuring each piece is well coated. Seal the bag or cover the dish and refrigerate for at least 30 minutes.
3. Preheat Oven: Preheat your oven to 400°F (200°C).
4. Sear Chicken: Heat vegetable oil in a large oven-safe skillet over medium-high heat. Remove the chicken from the marinade (reserve the marinade) and season with salt and pepper. Sear the chicken thighs skin-side down for about 5-7 minutes, until golden brown.
5. Flip and Add Marinade: Flip the chicken thighs over, pour the reserved marinade over them, and bring to a simmer.
6. Bake: Transfer the skillet to the preheated oven and bake for 20-25 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (75°C).
7. Glaze: For an extra sticky finish, broil the chicken for 2-3 minutes to caramelize the sauce slightly.
8. Garnish: Remove the chicken from the oven, and garnish with chopped green onions and sesame seeds if desired.
9. Rest: Allow the chicken to rest for a few minutes before serving.

Following these steps will lead you to an incredible meal that is both satisfying and delicious.
