Make the sauce: In a bowl, whisk together all sauce ingredients. It should make 2 cups of sauce. Reserve one cup of the sauce in the fridge for later thickening and serving.
3/4 cup soy sauce, 1/2 cup pineapple juice, 1/3 cup granulated sugar, 1/4 cup water, 4 cloves garlic, 2 Tbsp. rice vinegar, 1 Tbsp. fresh ginger, 1 tsp. fish sauce, 1 Tbsp. sesame oil
Marinate the chicken: Place chicken thighs in a bowl or zip-top bag and pour the remaining 1 cup of sauce over the top. Marinate for at least 30 minutes, or up to 8 hours. Start Timer
2 lbs boneless skinless chicken thighs
Bake: Preheat oven to 400°F. Remove the chicken from the marinade and arrange it on a baking sheet or in a baking dish sprayed with nonstick cooking spray. Discard marinade. You can spoon a couple of Tbsp. of the reserved marinade from the fridge onto the chicken if you’d like. Bake for 15 minutes, or until mostly cooked through. Start Timer
Thicken the sauce: Meanwhile, in a small bowl, whisk together cornstarch and water to make a slurry. Heat the reserved sauce in a small saucepan over medium heat. Stir in the slurry and cook until thickened and coats the back of a spoon, about 2–3 minutes. Start Timer
2 tsp. cornstarch, 2 tsp. water
Broil: The rack should be about 8-10 inches away from the heat source. Switch oven to broil and cook for about 5-8 minutes Start Timer, or until lightly charred and caramelized on top. Keep an eye on it so it doesn’t burn. I like to brush some of the thickened sauce on top of the chicken during the final broil minutes. Chicken should reach an internal temperature of 165°F in the thickest part of the chicken. Remove and loosely cover with foil for 5 minutes to rest. Start Timer
Serve: Slice or serve the chicken whole and spoon the thickened sauce over the top. Garnish with scallions, sesame seeds, and chili flakes if desired and serve over rice, udon noodles, veggies, etc. Sliced scallions, Sesame seeds, Chili flakes
