Step 1

In a small bowl, combine fish sauce, oyster sauce, sugar and water. Mix well and set aside.

Step 2

Heat 1 tbsp oil in a wok (or skillet) over med-high heat and add garlic and chilies. Stir-fry for 10 seconds, then add the beef. Stir-fry until the beef is no longer in pink, about 2 minutes. Transfer the beef to a plate and set aside.

Step 3

Add the remaining 1 tablespoon oil to the wok. Add the onion and the sauce. Stir-fry for 1-2 minutes until the onions are just soft.

Step 4

Add the beef and heat through. Add the basil leaves and remove the wok from the heat and shake everything to mix well. Serve immediately with jasmin rice.
