Prepare the Ingredients. Start by mincing the garlic and slicing the chilies and onion. Wash and pick the Thai basil leaves from the stems.
Make the Sauce. In a small bowl, combine the soy sauce, fish sauce, oyster sauce, brown sugar, and water. Stir until the sugar is dissolved.
Cook the Chicken. Heat a large pan or wok over medium-high heat. Add a bit of oil, then sauté the garlic and chilies until fragrant. Add the ground chicken and cook until it’s no longer pink (5-7 minutes), breaking it up with a spoon.
Combine and Stir-Fry. Pour the sauce over the chicken mixture and stir to coat evenly. Cook for another few minutes until the sauce is slightly reduced and the chicken is fully cooked.
Add Basil. Remove the pan from heat and stir in the fresh basil leaves. The residual heat will wilt the basil just right.
Serve. Serve hot over a bed of steamed jasmine rice and top with a fried egg for an authentic touch.
