1Heat oil in a wok over high heat until shimmering. Add chicken pieces and cook until golden and cooked through, about 8–10 minutes. Remove and set aside.
2In the same wok, add minced garlic and sliced shallot. Stir-fry for about 30 seconds until fragrant.
3Return chicken to the wok. Add fish sauce, oyster sauce, palm sugar, and sliced chilies. Toss everything together and cook for 2 minutes to combine flavors.
4Remove from heat and fold in thai basil leaves gently so they wilt into the dish but stay bright.
5Serve immediately over white rice. Spoon the pan sauce over each portion.
