Whip up the Marinade: In a small bowl or liquid measuring cup, combine the hot water and brown sugar sweetener, stirring until it fully dissolves. Then, mix in the low-sodium soy sauce, minced garlic, and ginger until everything is well blended. This creates your simple yet flavorful teriyaki marinade!
Marinate for Flavor: Place the chicken thighs into a large zip-top bag or a shallow dish. Pour the delicious teriyaki marinade over the chicken, ensuring each piece is thoroughly coated. Seal the bag or cover the dish and refrigerate for at least 1 hour, or for up to 48 hours for even deeper flavor.
Grill to Perfection: When you're ready to cook, preheat your grill to high heat (around 500°F). Carefully remove the chicken from the marinade, letting any excess drip off. Make sure to set aside the remaining marinade if you plan to make a glaze, or discard it if not used. Place the chicken thighs directly on the hot grill grates. Cook for 4-5 minutes per side until beautiful grill marks appear and the internal temperature reaches at least 165°F (for extra tender thighs, aiming for 185°F is ideal).
Make a Simple Glaze: Pour the reserved marinade into a small saucepan and bring it to a rolling boil over medium-high heat. Let it simmer for 5-8 minutes, stirring occasionally, until it thickens slightly. This ensures the glaze is safe to consume. For an even thicker glaze, you can mix 1 tablespoon of cornstarch with 2 tablespoons of water to create a slurry, then stir it into the simmering sauce until it reaches your desired consistency. Spoon this delicious, cooked-down glaze over your grilled chicken just before serving.
Serve & Enjoy: Garnish your healthy grilled teriyaki chicken with a sprinkle of sesame seeds and sliced green onions for an extra touch of flavor and freshness. It’s wonderfully satisfying and pairs beautifully with a side of grilled pineapple!
