Preheat the oven to 400°F (200°C) and line a baking sheet with foil for easy cleanup.
Season the chicken drumsticks with salt and black pepper.
Prepare the glaze by mixing orange marmalade, Dijon mustard, barbecue sauce, sambal oelek, and soy sauce in a bowl.
Coat the chicken with half of the glaze and arrange it on the baking sheet.
Bake for 15 minutes, then brush the remaining glaze over the drumsticks.
Continue baking for another 10 minutes until the chicken is caramelized and fully cooked (internal temperature of 165°F/75°C).
Broil for 2 minutes for extra crispiness, if desired.
Let it rest for a few minutes before serving. Enjoy with your favorite sides!
