Start by cutting your chicken into even, bite-sized pieces. This ensures they cook quickly and evenly. Pat the pieces dry with a paper towel to remove any excess moisture.
Mix soy sauce, honey, brown sugar, rice vinegar, sesame oil, garlic, and ginger in a bowl. Stir well to blend all the flavors. Don’t forget to whisk the cornstarch with water separately before adding it to the sauce. This prevents lumps!
Heat a non-stick skillet over medium heat and add the vegetable oil. Once the oil is hot, toss in the chicken pieces. Cook until golden brown, flipping occasionally (about 5–7 minutes).
Pour that beautifully whisked sauce over the chicken. Stir and coat evenly. Reduce the heat to low and simmer for about 10 minutes. The sauce will thicken and cling to the chicken. Keep an eye on it so it doesn’t burn!
Remove the pan from the heat, sprinkle sesame seeds generously, and add chopped green onions for that final touch.
