In a mixing bowl, combine honey, Sriracha sauce, soy sauce, minced garlic, olive oil, salt, and pepper. Mix well until the ingredients are thoroughly combined.
Place the chicken thighs in a large resealable plastic bag or a shallow dish. Pour the marinade over the chicken, making sure each piece is evenly coated. Seal the bag or cover the dish with plastic wrap. Marinate in the refrigerator for at least 1 hour, or preferably overnight, to allow the flavors to penetrate the meat.
Preheat your grill to medium-high heat, around 375-400°F (190-200°C). Make sure the grates are clean and lightly oiled to prevent sticking.
Remove the chicken thighs from the marinade, shaking off any excess. Place them on the preheated grill. Grill the chicken thighs for about 6-8 minutes per side, or until they are cooked through and have nice grill marks.
While grilling, you can brush the chicken thighs with some of the reserved marinade during the last few minutes of cooking for extra flavor. Be sure to discard any marinade that has come into contact with raw chicken to prevent contamination.
To check for doneness, use a meat thermometer inserted into the thickest part of the chicken thigh. The internal temperature should read 165°F (75°C), indicating that the chicken is fully cooked.
Once the chicken thighs are cooked through, remove them from the grill and transfer them to a serving platter. Allow the chicken to rest for a few minutes before serving. This helps redistribute the juices throughout the meat, ensuring a juicier bite.
Serve the Grilled Honey Sriracha Chicken Thighs hot, garnished with chopped cilantro or green onions if desired. These chicken thighs pair well with rice, grilled vegetables, or a fresh salad.
