Prepare the Ingredients. Start by mincing your garlic and chopping the bird’s eye chilies. If you're sensitive to spice, you can reduce the number of chilies or remove the seeds.
Cook the Meat. In a hot pan or wok, heat the vegetable oil and add the minced garlic, onion, and chilies. Stir-fry until fragrant, then add your ground pork or chicken. Cook the meat until browned and fully cooked.
Add Sauces. Once the meat is cooked, pour in the oyster sauce, soy sauce, fish sauce, and sugar. Stir well to coat the meat with the savory sauce.
Add Thai Basil. Toss in the Thai basil leaves and stir for a few seconds until they wilt. Remove from heat immediately to avoid overcooking the basil.
Fry the Egg. In a separate pan, fry your eggs until the edges are crispy and the yolk is still soft. This step is optional but adds an extra layer of richness.
Serve. Serve the stir-fried meat and basil over steamed jasmine rice and top with the fried egg.
