For the sauce and vegetables:
  • 2 teaspoons garlic finely minced
  • 2 large jalapeño peppers thinly sliced
  • ½ yellow onion thinly sliced
  • ⅓ cup soy sauce
  • ⅓ cup light brown sugar packed
  • ¼ cup cornstarch
  • ⅓ cup water
  • 1 teaspoon sesame oil
For serving:

  • Sesame seeds for garnish
  • These ingredients work together to create a sticky savory-sweet, and spicy chicken dish that feels restaurant-quality but is completely homemade.

Equipment

  • Large skillet or wok
  • Sharp knife
  • Cutting board
  • Measuring cups and spoons
  • Mixing bowl
  • Whisk or fork
  • Spatula or wooden spoon
  • Optional:
  • Rice cooker or saucepan for cooking rice

Method
 

Step 1:
  1. Cut the chicken thighs into bite-sized pieces. Pat them dry with paper towels, then season evenly with kosher salt and black pepper.
Step 2:
  1. In a small bowl, whisk together the soy sauce, brown sugar, cornstarch, water, and sesame oil until smooth. Set the sauce aside.
Step 3:
  1. Heat the olive oil in a large skillet or wok over medium-high heat. Once hot, add the chicken pieces in a single layer.
Step 4:
  1. Cook the chicken for 5–7 minutes, stirring occasionally, until it is browned on the outside and nearly cooked through. Remove excess moisture if needed to help with browning.
Step 5:
  1. Add the sliced onion and jalapeño peppers to the skillet. Stir and cook for 2–3 minutes until the onions soften slightly and the jalapeños become fragrant.
Step 6:
  1. Add the minced garlic and cook for about 30 seconds, stirring constantly to avoid burning.
Step 7:
  1. Pour the prepared sauce into the skillet. Stir well to coat the chicken evenly.
Step 8:
  1. Reduce the heat to medium and allow the sauce to simmer for 3–5 minutes, stirring frequently, until it thickens and becomes glossy.
Step 9:
  1. Once the sauce has thickened and the chicken is fully cooked, remove the skillet from heat.
Step 10:
  1. Sprinkle with sesame seeds and serve immediately over warm white rice.
