Vietnamese Beef & Watercress Salad (Bo Xao Xa Lach Xoong)

warm beef wilted watercress salad vietnamese bo xao xa lach xoong

Growing up, I loved hanging out at the nearby creek. I spent most of my days fishing for crawfish with a homemade fishing pole and a piece of bacon, while Mom collected watercress that grew abundantly along the muddy banks. Mom was very reluctant to cook up my catch of crawfish due to the questionable water, but she always took home the watercress where we had it in several dishes. 

The most traditional and popular way to use watercress in Vietnamese home cooking is in a salad with stir-fried beef and a tangy vinegar fish sauce dressing (Bo Xao Xa Lach Xoong). This can be served as a simple appetizer or one of the many sides dishes in a traditional home cooked Vietnamese meal. 

To make the salad, slice beef sirloin thinly then season with salt and pepper. Quickly pan-fry with a little vegetable oil and lots of garlic. Mix the stir-fried beef and all its juices with the watercress. The heat from the beef will wilt down the watercress and meld the flavors together. Lightly dress the salad with the fish sauce and vinegar dressing and top it with coarsely chopped roasted peanuts for a nice crunch.
