Preheat your oven to 400°F (200°C).
In a bowl, mix honey, soy sauce, red pepper flakes, olive oil, minced garlic, and black pepper.
Toss the chicken thighs in the marinade until they are well coated.
Place the chicken thighs on a baking sheet lined with parchment paper.
Bake the chicken for 25-30 minutes or until internal temperature reaches 165°F (75°C).
Optional: Broil for an additional 2-3 minutes for extra caramelization.
Remove from the oven and let rest for 5 minutes.
Garnish with chopped green onions and serve.
