Most of what pho tastes like comes out of one pot of broth. It is savory and lightly sweet, built on beef bones, and it finishes with a warm anise and cinnamon note. Charred ginger and onion, star anise, cinnamon, clove and fish sauce do the seasoning.
There is no heat in it. Chili, hoisin sauce and lime get added at the table, and each one pulls the flavor somewhere different.
Even the regional split is murkier than most pages make it sound. Tuoi Tre News (2021) calls northern pho salty and southern pho sweet, but Vietnam Airlines’ Hanoi guide describes the northern broth as naturally sweet.
What Does Pho Taste Like?
Savory first, sweet second. Under the broth sit rice noodles, thin-sliced meat and a handful of fresh herbs, but those only nudge the flavor around. The broth carries nearly all of it.
How one spoonful unfolds
Lift the bowl and the first thing you get is smoke from the charred onion and ginger, with star anise right behind it.
The sip itself is savory beef with a rounded sweetness underneath. Cinnamon and clove warmth show up late, along with a faint licorice note. Add lime, Thai basil or bean sprouts and the finish brightens.
What surprises first-time eaters
The missing heat catches a lot of people off guard. Chili and sriracha come from the table, not the pot.
The broth also goes into the bowl boiling, so the first spoonful needs a pause. And yes, there is fish sauce in there, but it adds depth rather than a fishy taste.
The flavor keeps moving as you add toppings, so the last spoonful doesn’t taste like the first.
Pho Broth Flavor: Savory Depth and Light Sweetness
Every part of the broth’s flavor traces back to a specific ingredient or step, which is why two bowls can taste so different.
Where the sweetness comes from
Charred onion and yellow rock sugar do most of the work. Tasting Table notes that charring caramelizes the sugars in onion and ginger, which adds a smoky, slightly bitter edge next to the sweetness.
Rock sugar rounds the broth out without making it taste like dessert. According to Tasting Table, its sweetness is milder and more delicate than granulated sugar’s, and Food Network Kitchen notes that granulated sugar can stand in for it.
Where the savory depth comes from
Knuckle and marrow bones give the broth its beefy depth and a silky, gelatin-rich body.
Fish sauce adds umami and a faint savory aroma, according to Orange Coast. Red Boat, a brand that makes its sauce in Vietnam from only anchovies and salt, says it ferments the sauce for 12 months.
Why the broth tastes clean, not greasy
Cooks agree on the method and disagree on the clock. Parboiling the bones and skimming during a low simmer produce the clarity.
Andrea Nguyen of Viet World Kitchen simmers beef pho broth for 3 hours total. Saveur’s short rib pho goes much longer and calls for a very low simmer of 6 to 8 hours. Parboiling the bones is enough for a clean, traditional broth, and roasting them first is the option for a beefier one.
So the shorter route gets you a clean, traditional broth, and the longer one gets you something deeper.
Seasoning runs strong on purpose. Nguyen says the broth should taste slightly over-seasoned, because the noodles and toppings go into the bowl unsalted.
That is also why a restaurant bowl can push sodium intake up even when the soup tastes light.
Which Spices Give Pho Its Aroma?
Star anise leads, with cinnamon and clove framing it. Cook’s Illustrated describes star anise as licorice-like, with herbal and lemony notes. Cinnamon is warm and sweet, and clove adds a spicy warmth that balances the sweeter spices.
Depending on the cook, coriander seed may go in too, which is light and lightly citrusy, or fennel seed, sweet and anise-like with piney notes. Cardamom turns up now and then as a warm background note.
Charred ginger and onion
Charring adds a smoky edge the dried spices cannot supply. Nguyen chars the skins until the flesh is slightly cooked and fragrant, and says the whole surface does not need to blacken.
Push it too far and the bitterness takes over. Tasting Table describes the char as slightly bitter even when done right, so the margin is small.
When the spices take over
Cook’s Illustrated names trans-anethole, at about 90%, as the dominant flavor compound in star anise. It is the same compound behind licorice.
That is why one extra pod shows up fast. The Cook’s Illustrated testers also picked out the difference when fennel or anise seed replaced star anise in a pho broth.
Too much star anise and the bowl tastes of licorice and not much else. With too little, you are basically drinking plain beef stock.
Noodle and Meat Texture in a Bowl of Pho
Banh pho noodles are soft and slightly chewy, and the meat runs from tender rare slices to firm brisket. Both change the bite of the bowl more than its flavor.
Banh pho noodles
Banh pho are flat rice noodles with a square or rectangular cross-section. CooksInfo says they have no real flavor of their own, but they absorb the broth well.
Texture depends on where you eat. In Vietnam the noodles are tender and soft, while Viet expats often prefer them more al dente, according to Nguyen.
Dried banh pho must be softened but kept chewy. The noodle types are covered in more detail in this guide to the kind of noodles pho uses.
Rare, cooked and fatty beef
| Cut | What it is | Texture in the bowl |
|---|---|---|
| Tai | Rare sliced beef | Tender, cooks in the hot broth |
| Chin | Well-done beef | Firmer, fully cooked |
| Nam | Flank | Fibrous, a more substantial bite |
| Gau | Fatty brisket | Rich, with a layer of fat |
Tai slices are thin enough to cook through when the boiling broth hits them.
For a first bowl, tai or chin is the easy pick. Jungle Boss Tours’ ordering guide suggests skipping gan (tendon) and sach (tripe) until you know you like the chewier textures.
Beef pho and chicken pho
Chicken pho tastes lighter and cleaner than beef pho.
Beef broth runs deeper and richer, with more body from the bones. Chicken broth, often a whole chicken simmered with ginger and shallots, comes out lighter and clearer.
Spicing varies by cook. Nguyen’s family flavors chicken pho with coriander seeds and cilantro to set it apart from beef pho, though some cooks use the same spices for both.
If you are choosing between them, here is how pho bo and pho ga differ in more detail.
Hanoi Pho vs Saigon Pho: Where the Taste Splits
Northern pho tastes savory and clear, a restrained bowl. The southern version is sweeter and richer, and its herb plate changes the bowl as you eat.
| Attribute | Northern (Hanoi) | Southern (Saigon) |
|---|---|---|
| Broth | Clear, savory, light | Richer, sweeter, murkier with herbs |
| Fat on top | Rarely visible | Often visible |
| Garnishes | Pickled garlic, chili sauce, fried dough sticks (quay) | Herb plate, bean sprouts, hoisin sauce, chili |
The fat and flavor rows come from Tuoi Tre News. Vietcetera and the Michelin Guide describe the garnish and clarity differences the same way.
Why the sweetness differs
Tuoi Tre News calls northern pho salty and savory and southern pho sweet. Vietnam Airlines’ Hanoi guide describes the northern broth as naturally sweet.
Read together, the sources point to two different origins for the sweetness. Vietcetera says Saigon cooks add sugar generously and use chicken bones to sweeten even beef pho, while Vietnam Airlines’ guide credits the Hanoi broth’s sweetness to the beef and spices.
In a Hanoi bowl the sweetness is what a good stock gives you anyway. In Saigon, some of it is added.
Noodle width: sources disagree
Vietcetera says Saigon noodles are thinner, closer to hu tieu strands, but Vietnam Airlines’ Hanoi guide says they run a bit thicker than Hanoi’s. Tuoi Tre News skips width and talks about shape instead, with square noodles in the south and flat ones in the north.
Width is a poor way to identify a style. Trust the garnish plate instead.
A northern bowl in the south
Phu Gia, a Saigon restaurant, has served northern-style pho for more than 20 years without herbs or hoisin sauce, according to Bac Ninh TV. One diner there says the missing herbs let him taste the broth, noodles and beef better.
Tuoi Tre News draws the same line for choosing a style. Go northern for a clear, savory bowl where the broth does the talking, or southern if you have a sweet tooth and like building your own bowl.
How to Adjust Pho at the Table
Taste the broth before touching anything, then add herbs and lime in small amounts. Chili comes after that, and sauces go last. Each addition pushes the bowl in a specific direction.
What each addition does
| Addition | Taste it adds | Watch for |
|---|---|---|
| Thai basil | Peppery, anise-like | A second licorice note |
| Culantro | Strong, slightly sweet cilantro flavor | Use a leaf or two |
| Bean sprouts | Crunch, mild sweetness | Blanching mellows them |
| Lime | Tart brightness | Can cloud the broth and dull its nuance |
| Hoisin sauce | Sweet and salty | Adds sweetness fast |
The herb descriptions come from the Michelin Guide Vietnam and Andrea Nguyen’s Pho Cookbook. Nguyen avoids lime in northern-style pho because she says it clouds the broth and dulls its nuance. She prefers garlic vinegar, which she says amplifies the broth without taking it in a totally different direction the way lime would.
A routine for adjusting a bowl
- Sip the broth plain first. It shows what the kitchen did before you change anything.
- Add herbs and sprouts by the leaf or sprig, not the whole plate.
- Squeeze in some lime or spoon in garlic vinegar, then taste again.
- Add sliced chili a little at a time.
- Use sauces last. Dip the meat, or stir them in only if the broth needs help.
A longer walkthrough of the routine sits in this guide on how to eat pho.
Dip the sauce or stir it in?
Chef Tyler Akin of Stock in Philadelphia said in a Bon Appetit video that hoisin sauce and sriracha ruin the broth, and told viewers to squeeze in all the lime they get. Tuoi Tre News reported that some Vietnamese diners agree and serve sauces in separate small dishes.
Others see it differently. One Vietnamese commenter in the same article was surprised by how much sriracha and hoisin sauce Saigon diners add, yet still said taste is personal.
The split tracks the regional habits above. Dipping keeps the broth the same for the whole bowl, while stirring changes every spoonful after it.
Pho Compared With Ramen and Other Soups
Pho is lighter and more aromatic than ramen, and it sits well away from chicken noodle soup. Bun bo Hue is the closest relative and the spiciest.
| Soup | Broth | Noodle | Dominant flavor |
|---|---|---|---|
| Pho | Light, clear, spiced | Flat rice noodles | Aromatic, savory-sweet |
| Ramen | Heavier, often cloudy | Wheat noodles with kansui | Hearty, salty-savory |
| Chicken noodle soup | Mild chicken stock | Egg or wheat noodles | Mild, herbal |
| Bun bo Hue | Reddish pork-and-beef, lemongrass | Thick round rice noodles | Spicy, funky |
Pho vs ramen: where the variation lives
Daily Meal says ramen varies through its broth seasoning, while pho varies through its toppings, and that pho does not usually come with an egg.
Chowhound gives ramen the more vibrant, complex profile and calls pho’s strength its simple, straightforward taste. Both sources treat pho as the lighter soup, though Chowhound sees that simplicity as a strength rather than a flaw.
Pho vs chicken noodle soup
Chicken noodle soup gets its flavor from the stock and whatever cooks in it. Pho gets part of its flavor after the bowl is poured, from the herbs and lime you add, plus chili if you want it.
Pho vs bun bo Hue: how close are they?
Sources disagree on the distance. World Travel Family says pho bo tastes fairly similar to bun bo Hue, with the Hue soup carrying more spice and lemongrass, while Marion’s Kitchen says the two have very different flavor profiles.
Greatist notes that pho has mild flavors and needs added heat, while bun bo Hue builds a balance of sweet, salty, spicy and umami notes into the pot. Shrimp paste supplies the funk, and most people who enjoy the soup do not pick it out on its own, according to a Designbeep guide.
Both are noodle soups on a bone broth with herbs on the side, and they still don’t taste alike.
When Pho Will Disappoint
Sometimes the problem is your palate and sometimes it’s the bowl. Only the second is the kitchen’s fault.
Palates that clash with pho
Anyone who hates licorice will struggle, since star anise sits in the broth and Thai basil adds a second anise-like note on top, per the Michelin Guide Vietnam.
Heat seekers are on their own too. The broth is mild, so the heat depends entirely on the chili you add. And if richness is what you are after, a clear pho broth can read thin next to a thick ramen broth.
When cilantro tastes like soap
A study in the journal Flavour put the share of people who dislike cilantro at 21% among East Asians and 17% among Caucasians, as Chowhound reports.
A separate genome-wide study in Flavour, covering 14,604 people of European ancestry, linked soapy-taste detection to a variant near a cluster of olfactory receptor genes that includes OR6A2.
Vietnam Airlines’ Hanoi food guide lists fresh cilantro among the toppings for northern pho. Ask for the bowl without it, or skip the herb plate. The broth does not depend on it.
Signs of a poor bowl
A flat, salty broth has salt with no beef or spice behind it. Sweetness that comes only from sugar sits on the tongue with no savory depth under it. Heavy fish sauce is another giveaway, since LovingPho notes a pho broth should not need much of it.
Temperature matters more than people expect. If the broth is lukewarm, the rare beef stays raw, because the broth has to be hot enough to cook it. Noodles also keep softening in hot broth, so a bowl left sitting turns to paste.
None of these is a reason to give up on pho. They are reasons to try a different shop.
Common Questions About the Taste of Pho
Does pho taste like beef stew?
No. Pho broth is clear and light, built on star anise, cinnamon and charred aromatics, while stew is thick and hearty.
Vietnamese-style beef stew is spiced differently too, with lemongrass, curry powder, chili and tomato among its aromatics, according to Boyle McCauley News.
What does vegetarian pho taste like?
Vegetarian pho (pho chay) tastes lighter and cleaner than beef pho, with umami from mushrooms or miso instead of bones. The same star anise and cinnamon carry the pho aroma.
Ask for pho chay by name. Kimecopak’s guide warns that a “no meat” request can still land in a meat-based broth.
How does pho smell?
Pho smells of sweet, anise-like spice over smoky roasted onion and ginger, with a savory beef undertone. The licorice-like top note is star anise, and the smoke comes from the char on the aromatics.
Is there MSG in pho?
Often, yes. Local Vietnam’s guide says MSG is used heavily in Vietnamese cooking, particularly at street stalls and local restaurants, and Nguyen notes that for many Vietnamese people it is part of pho’s flavor profile.
It adds umami to the savory base. If you avoid it, ask the restaurant before ordering.
Choosing Your First Bowl of Pho
A northern-style pho bo with rare or well-done beef makes the best first bowl. The clear, restrained broth sets a baseline before sweetness and herbs start moving the flavor.
If you plan to eat your way through several, start with the northern bowl. Follow it with a southern one and the full herb plate, then pho ga to see how a lighter broth compares.
The catch is that a northern first bowl is plainer and less sweet. Anyone with a sweet tooth should still order the southern bowl before deciding, since one northern spoonful can read as austere.
