Recipe Notes

(1) To make it easier to slice the beef, place in the freezer for 15 minutes. 

(2) You can find frozen minced lemongrass in the freezer section of international groceries. If you can't find it, replace with fresh lemongrass but using white part only. 

(3) Chicken powder gives it more flavor, you can omit if you don't have it on hand. 

It is best to stir fry beef in batches to avoid crowding the pan. I have a medium skillet and cooked the beef in two batches. Also high heat is very important so make sure the skillet is extremely hot before adding in the beef. 

To save time, while the beef is resting, prepare the noodles, herbs and dipping sauce.
