Vietnamese beef noodle salad (bun bo xao) is packed with fresh herbs, flavorful beef, and refreshing lime fish sauce dressing. It takes only 30 minutes to make, and you can enjoy it either as a main or side dish.

Overview of Vietnamese Beef Noodle Salad (Bun Bo Xao)
Vietnamese Beef Noodle Salad goes by “bun bo xao” or “bun bo Nam Bo” in Vietnamese. A bowl of this tasty noodle salad is usually substantial enough to be a full meal by itself. I think this dish says quite a lot about Vietnamese cuisine which values a fresh, pure and clean taste.
If you visit Hanoi, it is quite easy to find a street food shop selling this dish. Bun Bo Xao and Bun Cha (Vietnamese grilled pork meatballs with noodles) are two popular noodle street food dishes in Hanoi.
It is super easy to replicate this noodle salad at home. Stir-fried beef and colorful vegetables and herbs are placed on a bed of soft vermicelli noodles. To make it even more delicious, we sprinkle it with crunchy fried shallots and roasted peanuts.
We then drizzle Vietnamese signature fish sauce dressing over the salad and give it a good mix before eating. Simple as it may sound, it is a feast to the eyes and stomach.
Cooking Vietnamese Beef Noodle Salad (Bun Bo Xao)
Ingredients
The main ingredients for this dish are beef, rice vermicelli noodles (bun), your choice of vegetables and fresh herbs.
Fried shallots and roasted peanuts are somewhat optional, but their crunchiness and nuttiness do increase the deliciousness. You can buy fried shallots packed in a jar at Asian grocery stores.
My favorite beef cut for stir-frying is flank steak which is very flavorful. It becomes tender when marinated long enough. I recommend using flank steak, slice it against the grain as thinly as you can and marinate for about 25-30 minutes.
You can certainly choose another cut you like. The key here is to slice it against the grain thinly, marinate, and stir-fry in small batches.
In terms of vegetables, there is an array from which you can choose. I usually use at least two types of vegetables from this list:
- lettuce,
- micro greens,
- bean sprouts,
- carrot,
- cucumber
As for herbs, I often choose mint and cilantro for their refreshing flavor and not too strong aroma.
If you cook Vietnamese food frequently, it is always a good idea to have a pack of rice vermicelli noodles in the pantry. My favorite brand is Bamboo Tree (Ba cay tre). After trying several brands, I can conclude that their vermicelli noodles are the best.
If your local Asian grocery stores don’t carry Bamboo tree vermicelli noodles, the second best brand to try is Three Ladies Brand Rice Vermicelli.
Some Products I Used to Make this Dish
- Bamboo Tree vermicelli noodles, the best vermicelli noodle brand. If you cannot find it, get Three Ladies brand.
- Red Boat fish sauce, which contains just anchovies and salt. It doesn’t contain sugar or any weird ingredients.
- Oyster sauce
- Scanpan nonstick skillet: I like my stainless steel and cast iron skillets a lot, however Scanpan is my go-to skillet when I need to stir-fry thinly-sliced meat. Hand wash it and don’t use metal utensils and it will last for a while.
Cooking notes
It may be a matter of preference, but I like to eat my Vietnamese beef noodle salad warm. To do that, everything else must be ready before stir-frying the beef.
The noodles can be warmed up by running them through hot water very briefly or microwaving them quickly. To warm up the dressing, you can microwave it for about 30 seconds.
Put the noodles, veggies and herbs in the serving bowls, and then stir-fry the beef. Add the beef to the bowls, sprinkle peanuts and fried shallots, then serve immediately with the dressing.
This Lemongrass Pork Noodle Salad (Bun Thit Xao) is also delicious and the cooking method and many of the ingredients are similar. You may want to check it out since I made a video showing how to make it as well as how to slice cucumbers quickly for noodle salad.

To warm up the dressing, you can microwave it for about 30 seconds. Put the noodles, veggies and herbs in the serving bowls, and then stir-fry the beef.
- Work in small batches when stir-frying the beef if needed. I stir-fry 1 lb of beef in 3 batches.

What can I use as a substitute for Oyster sauce?
That’s the only ingredient I don’t have 🙁
Sophie
Hi Noni,
You can add a dash of soy sauce instead. It’s slightly different but should be fine. Other options may be recap manis or hoisin sauce but I’ve never tried myself. Please feel free to season the beef to your liking :).
Mary
Yum. Looks tasty. I’ll have to try this out.

Hi Sophie, First off you have a great blog and i am loving it. mainly because you have all of the recipes I have been looking for since moving away from my source for all Vietnamese cooking connections I had in CA , So thank you for what you have created here. Its really special and your doing a great job. I like that you have English titles that included the veitnamese words after them, this is very helpful. Also the pictures are great showing the labels of what to buy, this helps when i go to H Mart to find the right brand. On this note can you tell me what brand of oyster sauce is the best to use? Loved the link for the fish sauce that was very helpful.
thank you, Wes

Hi Wes,
Thank you so much for your kind words! I greatly appreciate it and comments like yours are the reasons why I enjoy sharing Vietnamese recipes on the blog. I’m very happy to know that you find my information and links for ingredients helpful. For oyster sauce, I usually buy Lee Kum Kee oyster sauce. It is available in all Asian grocery stores as well as many Western grocery stores. Dynasty brand is good too, and cheaper than Lee Kum Kee if I remember correctly. Please let me know if you have other questions :).
Thanks again,
Sophie
