Prepare the ingredients. Wash the chicken thoroughly, then fry until the skin is crispy. Remove from heat.

Sauté the garlic and onion until fragrant, then add water. Add salt, sugar, sweet soy sauce, oyster sauce, and ground pepper. Stir until well mixed.

Add the chicken, cook until the chicken is tender, the flavors are absorbed, and the sauce thickens. Adjust seasoning to taste.
