Follow these steps to create the mouthwatering Spicy Sweet Chicken Diablo:

1. Prepare the Marinade: In a mixing bowl, combine pineapple juice, soy sauce, honey, sriracha sauce, minced ginger, minced garlic, and red pepper flakes. Whisk until well combined.
2. Marinate the Chicken: Place the chicken breasts in a large resealable bag or shallow dish. 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).
3. Preheat the Oven: Preheat your oven to 400°F (200°C).
4. Prepare for Baking: Line a baking sheet with aluminum foil or parchment paper for easy cleanup. Remove the chicken from the marinade, allowing excess marinade to drip off.
5. Bake the Chicken: Place the chicken breasts on the prepared baking sheet. Drizzle with sesame oil for added flavor. Bake in the preheated oven for 25-30 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (74°C).
6. Glaze the Chicken: During the last 5 minutes of baking, brush the chicken with any remaining marinade for an extra layer of flavor.
7. Rest the Chicken: Once done, remove the chicken from the oven and let it rest for 5 minutes. This allows the juices to redistribute, ensuring tender chicken.
8. Slice and Serve: Slice the chicken into strips or serve whole. Drizzle with additional glaze if desired.

By following these steps, you’ll create an incredible dish that perfectly balances spicy and sweet.
