Prepare the marinade by combining soy sauce, honey, sriracha, minced garlic, grated ginger, sesame oil, and rice vinegar in a bowl.
Add the chicken thighs to the marinade, making sure they are fully coated, then refrigerate for at least 30 minutes.
Preheat the oven to 400°F (200°C).
Transfer the marinated chicken to a baking dish and pour any remaining marinade over the top.
Bake in the oven for 25-30 minutes until the chicken is cooked through and the internal temperature reaches 165°F (75°C).
Remove the chicken from the oven and let it rest for 5 minutes before serving.
Garnish with chopped green onions before serving.
