Vietnamese noodle bowls come with a side plate of fresh herbs. Here's every herb identified, its purpose, and where to find it in the US.

When you order phở or bún bò Huế at a US Vietnamese restaurant, a separate plate arrives with a pile of fresh herbs, bean sprouts, lime wedges, and chilies. Most Western diners pick a few familiar leaves and ignore the rest. That's a mistake — each herb on the plate does specific work in the bowl.
This guide identifies every herb you'll see and explains what it's for, so you can use the plate intentionally.
| Herb | Vietnamese Name | Use | Substitute |
|---|---|---|---|
| Thai basil | Húng quế | Anise-sweet brightness | Italian basil (close enough) |
| Cilantro | Ngò rí | Citrus-grassy lift | None — use parsley reluctantly |
| Mint (spearmint) | Bạc hà | Cool, sweet, palate cleanse | Regular mint |
| Perilla | Tía tô | Earthy, slightly bitter, anise notes | None — skip if unavailable |
| Vietnamese coriander | Rau răm | Peppery, sharp, often in chicken phở | None — distinct flavor |
| Culantro / sawtooth herb | Ngò gai | Stronger version of cilantro | Cilantro + bay leaf |
| Bean sprouts | Giá đỗ | Cold crunch, texture contrast | None |
| Lime wedges | Chanh | Acid to brighten broth | Lemon, but worse |
| Thai chili | Ớt | Heat | Jalapeño or serrano |
The traditional Vietnamese order for adding herbs to phở:
Don't add everything at once. Each herb has a different cooking time in the broth, and timing the additions changes the bowl significantly.
Some herbs are mainstream in Vietnam but rare in US grocery stores. Where to find them:
If you can only find Western mainstream herbs, Thai basil + cilantro + mint + lime gets you 80% of the way to authentic.
Most Vietnamese herbs grow well in US climates. Thai basil, mint, perilla, and Vietnamese coriander all do fine in containers on a sunny windowsill or balcony. Many Vietnamese-American households grow their own — and once you do, you stop noticing the difference between restaurant phở and homemade.
Seed sources:
The presence of an herb plate is the diagnostic sign of a real Vietnamese restaurant. Cheap pan-Asian restaurants skip it (or send a sad scoop of bean sprouts and lime). Real Vietnamese restaurants send a generous plate that's bigger than it needs to be.
If your bowl of phở comes without a side plate, you're at a Vietnamese-themed restaurant, not a Vietnamese restaurant. Take note.
