Ingredients

For the chicken

  • 1 pound boneless skinless chicken breasts
  • ¼ cup cornstarch
  • 2 tablespoons vegetable oil, divided

For the sauce

  • 1 small shallot, diced
  • 1 clove garlic, minced
  • 1 thumb-sized piece of ginger, minced
  • ½ cup soy sauce, *use tamari for gluten-free
  • 3 tablespoons maple syrup
  • 2 tablespoons gochujang, Korean chili sauce
  • 2 tablespoons rice wine vinegar
  • 1 tablespoon cider vinegar, optional
  • 1 tablespoons toasted sesame oil

To Serve:

  • Steamed tenderstem broccoli or kale
  • Steamed white rice

Instructions

  • Cut the chicken into chunks and toss them in cornstarch to coat evenly. Set aside.

To make the sauce

  • Heat a heavy-bottomed saucepan on medium heat. Add a tablespoon of vegetable oil, then sauté the shallot, garlic, and ginger until softened and fragrant.
  • Stir in the soy sauce, maple syrup, gochujang, and both vinegars. Bring the mixture to a boil and let simmer for 1 minute until the sauce thickens slightly. Stir in the sesame oil.

To make the chicken

  • In a separate skillet, heat the remaining vegetable oil over medium-high heat. Add the diced chicken and cook until the exterior is crispy and golden and the interior is fully cooked.
  • Once the chicken is cooked, pour the sauce into the pan with the chicken and toss to coat. Serve the chicken over hot white rice with a side of green vegetables like broccoli or kale.

Notes

  • Adjusting heat: the amount of gochujang based on your preference for heat. Gochujang is moderately spicy but also brings a unique, complex flavor. Start with less if you're sensitive to spice, or add more for an extra kick. 
  • Gochujang: If gochujang is unavailable, consider using a mix of red chili paste and a little honey or sugar to mimic its sweet heat.
  • Maple Syrup: Honey or brown sugar can be substituted for maple syrup if preferred.
  • Rice Wine Vinegar: Apple cider vinegar or white wine vinegar are good alternatives if rice wine vinegar is unavailable.
  • Cornstarch Coating: Ensure the chicken is dry before tossing it with cornstarch. This helps in getting a crisper finish when cooked.
  • Sauce Consistency: If the sauce is too thick, thin it with a little water or additional soy sauce for the right consistency.
  • Sautéing Aromatics: Cook the shallot, garlic, and ginger on low heat to avoid burning, which can impart a bitter taste to the sauce.
  • Garnish: Sprinkle toasted sesame seeds or sliced green onions on top for added texture and a pop of color.
  • Vegetable Options: In addition to broccoli and kale, bok choy or snap peas make great green additions that cook quickly and add crunch.
  • Prep Ahead: Chop the chicken and vegetables and prepare the sauce a day ahead; store separately in the refrigerator to make dinner prep even faster.
  • Storage: Leftovers can be stored in an airtight container in the refrigerator for up to three days. Reheat gently to avoid overcooking the chicken.
