Why You’ll Love This Recipe
This lemongrass beef Vietnamese recipe hits every note — savory, slightly sweet, smoky from a good char, and just the right amount of heat. It works beautifully as a quick weeknight stir fry or as the star of a full Bun Bo Xa Ot noodle bowl.

Instructions
- Make the marinade: Using a mortar and pestle, crush 1 tablespoon sugar, 1 tablespoon minced ginger, 2 crushed garlic cloves, 1 tablespoon minced lemongrass, and 1 sliced Thai chili into a rough paste.
- Toss the paste with the thinly sliced beef, 1 tablespoon fish sauce, oyster sauce, and 1 tablespoon oil. Cover and refrigerate for at least 1 hour, or overnight for the deepest flavor.
- Make the fish sauce dressing: Crush 2 tablespoons sugar, the remaining 1 tablespoon ginger, 4 garlic cloves, and 2 to 4 Thai chilies into a fine paste. Transfer to a jar, then stir in 2 tablespoons fish sauce and 1 cup water. Refrigerate until ready to serve.
- If making quick pickled cucumbers, toss the sliced cucumber with 1 teaspoon salt and 1 tablespoon sugar. Let stand for 15 minutes, then rinse with cold water and pat dry.

Tip on fish sauce: Not all fish sauce is the same. Look for a good quality Thai or Vietnamese brand — it makes a real difference in the depth of flavor. Check out Serious Eats’ guide to the best fish sauce brands if you’re not sure what to grab.
Step-by-Step Instructions
Step 1: Marinate the Beef (At Least 1 Hour, Overnight Is Best)
Grab your mortar and pestle. Crush 1 tablespoon of sugar, half the ginger, 2 garlic cloves, half the lemongrass, and 1 Thai chili into a rough paste. It doesn’t have to be totally smooth — you just want everything bruised and fragrant.
Toss this paste with the thinly sliced beef, 1 tablespoon each of fish sauce, oyster sauce, and oil. Mix well so every piece is coated. Cover and refrigerate for at least 1 hour. Overnight really is better — the beef absorbs all those aromatics and the char you get when cooking is next level.
Pro tip: Slice the beef as thin as you can — around 1/8 inch. Pop it in the freezer for 20 minutes first and it’ll be so much easier to slice.
Step 2: Make the Fish Sauce Dressing
In the same mortar and pestle, crush the remaining 2 tablespoons of sugar, 1 tablespoon of ginger, 4 garlic cloves, and 2–4 Thai chilies into a fine paste. Start with 2 chilies if you’re spice-cautious and work your way up.
Transfer the paste to a jar, add 2 tablespoons of fish sauce and 1 cup of water. Give it a good stir, seal it, and refrigerate until you’re ready to serve. This dressing keeps well for up to a week — make extra and put it on everything.
Step 3: Cook the Vermicelli and Prep Your Vegetables
When you’re ready to eat, cook the vermicelli according to package directions — usually about 3 minutes in boiling water. Drain and rinse well with cold water to stop cooking and prevent clumping. Set aside.
While the noodles cook, prep your vegetables. Slice the cucumber and cabbage, chop the herbs, and get your lime wedges ready. This is also the perfect time to make quick pickled cucumbers if you want them.
How to Make Quick Pickled Cucumbers
Thinly slice 1/4 of an English cucumber. Toss with 1 teaspoon salt and 1 tablespoon sugar. Let it sit for 15 minutes — you’ll see it start to release liquid and soften. Rinse in cold water and pat dry.
These little guys add the most perfect tangy crunch to the bowl. Totally optional but highly recommended. They’re similar to the pickled vegetables you’d find in a classic Vietnamese-style soup bowl.
Step 4: Fry the Lemongrass
Heat a large nonstick skillet over medium heat with 1 tablespoon of oil. Add the remaining tablespoon of minced lemongrass and fry until it turns crispy and golden brown. This takes about 2–3 minutes — watch it closely so it doesn’t burn.
Drain the fried lemongrass on a paper towel and set it aside, but keep the infused oil in the pan. That oil is now packed with flavor and you’ll use it to cook the beef. Don’t waste it!
Step 5: Sear the Beef
Turn the heat up to medium-high. Add the marinated beef to the skillet in a single layer. Let it sit without moving for 1–2 minutes so it gets a proper char on one side, then flip.
You want good color here — don’t rush it. If your pan is small, cook the beef in batches rather than crowding it. Crowded beef steams instead of sears, and that gorgeous char is what makes this vietnamese lemongrass beef stir fry recipe so good.
Step 6: Assemble the Bowl
Now comes the fun part. Arrange vermicelli noodles in a bowl, then layer on the vegetables, charred beef, and any fresh herbs you like. Drizzle generously with about 1/4 cup of the fish sauce dressing.
Top with fried lemongrass, fried shallots, sliced chilies, and a big squeeze of lime. Every single topping adds something — don’t skip the fried shallots. They’re crispy, savory little flavor bombs.
Expert Tips, Variations, and Troubleshooting
Tips for the Best Char
A hot pan is your best friend here. If the skillet isn’t properly hot before you add the beef, you’ll get grey steamed meat instead of caramelized, charred perfection. Give it at least 2 minutes to heat up before adding anything.
Also, make sure your beef is as dry as possible before it hits the pan. Pat it down with a paper towel if the marinade looks very wet. Surface moisture = steaming, not searing.
Ingredient Swaps and Variations
No fresh lemongrass? Frozen or jarred minced lemongrass works in a pinch, though fresh gives a brighter flavor. You can find fresh lemongrass at most Asian grocery stores — it’s worth the trip.
If you can’t find Thai chilies, a red Fresno chili or even a jalapeño will do the job. Adjust the quantity based on your heat preference.
This recipe also works beautifully with chicken thighs or even pork shoulder sliced thin. The marinade is incredibly versatile — kind of like a Vietnamese all-purpose seasoning blend.
Troubleshooting Common Issues
If your beef tastes flat, the most common culprit is under-marinating. Give it the full overnight soak whenever possible. Another option is to check your fish sauce — low-quality brands can taste thin and salty rather than rich and complex.
If the dressing tastes too sharp, add a little more sugar or a splash more water. It should be tangy, savory, and slightly sweet — not mouth-puckeringly sour.
Storage Instructions
| Component | Storage Method | How Long |
|---|---|---|
| Cooked beef | Airtight container in fridge | Up to 3 days |
| Fish sauce dressing | Sealed jar in fridge | Up to 1 week |
| Cooked vermicelli | Airtight container, tossed in a little oil | Up to 2 days |
| Fresh herbs and veg | Wrapped in damp paper towel, in fridge | Up to 2 days |
| Marinated raw beef (uncooked) | Covered in fridge | Up to 24 hours |
Reheating Tips
To reheat the cooked beef, the best method is a quick toss in a hot skillet for 1–2 minutes. This revives the char and keeps the texture right. Microwaving works in a pinch but the beef can turn chewy.
Keep your noodles, dressing, and toppings separate in the fridge and assemble fresh bowls each time. That way everything stays at its best rather than getting soggy.
No-Waste Kitchen Ideas
Leftover beef works great in a lettuce wrap the next day — just add some sliced cucumbers, a drizzle of the dressing, and you’ve got lunch sorted. The fish sauce dressing is also amazing as a dipping sauce for fresh spring rolls.
Don’t toss the lemongrass stalks after mincing — simmer them in hot water for a fragrant herbal tea, or add them to a pot of rice for subtle flavor. Vietnamese cooking is all about using everything.
Frequently Asked Questions
Can I make this Vietnamese lemongrass beef recipe ahead of time?

Absolutely. Just reduce or skip the Thai chilies in both the marinade and the dressing. The dish still has plenty of flavor from the lemongrass, garlic, and ginger. You can always serve sliced chilies on the side so everyone can customize their heat level.
Do I have to use a noodle bowl, or can I serve this differently?
