Ingredients
  

  • 1.5 pounds boneless, skinless chicken breasts or thighs, cut into 1-inch pieces
  • 2 tablespoons soy sauce (low sodium if preferred)
  • 1 tablespoon sesame oil or olive oil
  • 2 cloves garlic, minced
  • 1 teaspoon fresh ginger, grated (or 1/2 teaspoon ground ginger)
  • 1/2 teaspoon black pepper
  • 1 tablespoon brown sugar or honey (for marinade)
  • Neutral oil for grilling (canola or avocado oil)
  • Wooden or metal skewers (optional)
  • 1/2 cup ketchup
  • 1/3 cup rice vinegar (or apple cider vinegar)
  • 1/4 cup brown sugar
  • 2 tablespoons soy sauce
  • 1 tablespoon honey (optional, for extra gloss)
  • 1 tablespoon cornstarch + 2 tablespoons water (slurry)
  • 1/2 cup pineapple juice or water (pineapple juice adds classic flavor)
  • Pinch of red pepper flakes (optional)

Method
 

  1. Prep the chicken: Pat the chicken dry and cut into 1-inch pieces. Dry chicken browns better and cooks evenly.
  2. Make the marinade: In a bowl, mix soy sauce, sesame oil, garlic, ginger, black pepper, and brown sugar or honey.
  3. Marinate briefly: Toss chicken with the marinade. Let sit 20–30 minutes at room temperature, or up to 2 hours in the fridge.
  4. Soak skewers if using: If using wooden skewers, soak them in water for 20–30 minutes to prevent burning.
  5. Preheat the grill: Heat to medium-high (about 425–450°F). Clean and oil the grates to reduce sticking.
  6. Skewer or not: Thread chicken onto skewers with slight gaps, or grill the pieces directly. Brush lightly with neutral oil.
  7. Grill the bites: Cook 6–8 minutes total, turning every 2 minutes. Aim for nice grill marks. Internal temp should reach 165°F.
  8. Rest the meat: Transfer to a plate and rest 3–4 minutes to keep juices in.
  9. Make the sauce: In a small saucepan, combine ketchup, vinegar, brown sugar, soy sauce, honey, and pineapple juice. Bring to a simmer over medium heat.
  10. Thicken: Stir in the cornstarch slurry, whisking until glossy and slightly thick, 1–2 minutes. Add red pepper flakes if you like heat.
  11. Serve: Pile the chicken bites on a platter. Serve sauce on the side for dipping or toss lightly to coat. Garnish with sesame seeds and green onions.
