Step 1: Prepare the Marinade
In a mixing bowl, combine the minced lemongrass, garlic, shallot, soy sauce, fish sauce, oyster sauce, honey, black pepper, salt, and sriracha (if using). Stir well to create a fragrant marinade. Add the chicken pieces and toss to coat evenly. Let it marinate for at least 30 minutes, but for the best flavor, refrigerate it for 2–4 hours.
Step 2: Cook the Chicken
Heat a large skillet or wok over medium-high heat and add the vegetable oil. Once the oil is hot, add the marinated chicken in a single layer, making sure not to overcrowd the pan. Let it sear for about 2–3 minutes without stirring, allowing a nice golden-brown crust to develop.
Flip the chicken pieces and continue cooking for another 4–5 minutes until fully cooked and slightly caramelized. If you want a slight glaze, dissolve 1 teaspoon of cornstarch in 1 tablespoon of water and pour it into the pan. Stir well and cook for another minute.
Step 3: Garnish and Serve
Transfer the cooked chicken to a serving plate and sprinkle fresh cilantro and sliced green onions on top. Serve hot with steamed rice and lime wedges on the side for an extra burst of freshness.
