Quy Nhơn and the fishing towns up and down the central coast turned bánh canh into a workday staple during the lean bao cấp years, when a bowl needed to stretch a small catch across a family meal without pretending to be anything fancier than it was. Cheap fish frames became a clean, sweet broth; odd cuts and bycatch became chả cá, fried fish cakes bound with a little starch. It's humble food built on the same instinct that runs through most of Vietnamese cooking under scarcity — waste nothing, and let long simmering do the flavor work that expensive cuts would otherwise provide.
The noodle itself is the small marvel here: bánh canh's tapioca-rice dough gives it a chew no wheat noodle replicates, thick and glassy and slippery against the fish cake's crisp edge. Fry the chả cá twice — once to set it, once to wake it back up — and the bowl earns its place beside phở and bún bò as one of the country's three great noodle-soup traditions, even if it rarely gets the postcard treatment the other two do.
Fry the fish cakes in two stages — once to set the crust, once just before serving to re-crisp it. A cake fried once and left to sit in broth goes soft in minutes; the second fry is what keeps the bite.

Ingredientsnguyên liệu
Serves 4
The fish cakes (chả cá)
- 500 gfirm white fish fillet — about 1 lb — mackerel or wahoo are traditional on the central coast; snapper or cod work fine off the boat
- 1.5 tbspfish sauce
- 1 tbspsugar
- 2 tsptapioca starch
- 1 tspbaking powder — for spring, the same trick as nem nướng's paste
- 1 tspground white pepper
- 60 mlneutral oil, for frying — 1/4 cup
The broth
- 1.5 kgfish bones and heads, or a whole cheap fish — about 3 lb — ask the fishmonger for frames; this is where the broth's clean sweetness comes from
- 2.5 lwater — 10 cups
- 2shallots, charred
- 2 cmginger, sliced and charred — charring the aromatics on a dry pan or open flame first keeps the broth clear instead of murky
- 2 tbspfish sauce
- 1pinch sugar
- 1pinch salt
To finish
- 500 gfresh bánh canh noodles (tapioca-rice) — about 1 lb — thick, round, and translucent-white; sold fresh or frozen at Vietnamese markets. No honest substitute matches the chew, but fresh udon in a pinch gets you a soup that's genuinely good, just wheat-soft instead of tapioca-springy — say so if you serve it that way
- 2scallions, sliced
- 2 tbspfried shallots
- 1lime, cut into wedges
- 1chili, sliced, or chili oil
Methodcách làm
Step 1: Make the fish paste
Blitz the fish fillet with fish sauce, sugar, tapioca starch, baking powder, and pepper in a food processor until it turns pale and sticky and pulls away from the sides — about 90 seconds. Chill the paste 15 minutes; cold paste shapes cleanly and fries with a better crust than paste straight from the processor.
Step 2: Shape and first-fry the cakes
With wet hands, shape the paste into flat discs about 6 cm across and 1 cm thick. Shallow-fry in the oil over medium heat, 2–3 minutes a side, until golden and just cooked through, then drain on paper. This first fry sets the shape and can be done hours ahead.
Step 3: Build the broth
Rinse the fish bones well, then simmer with water, charred shallot, and charred ginger for 30 minutes, skimming foam in the first 10. Strain through a fine sieve, discard the solids, and season with fish sauce, sugar, and salt to a broth clean enough to drink on its own — this soup has few toppings, so the broth is doing most of the talking.
Step 4: Cook the noodles
Boil the bánh canh noodles directly in a separate pot of water until they turn glossy and lose their opaque core, 4–6 minutes for fresh, longer for frozen — check the package, since brands vary more than most noodles. Drain and portion straight into bowls; unlike rice vermicelli, they don't need a cold rinse.
Step 5: Re-fry the fish cakes
Just before serving, fry the cakes again for about a minute a side to re-crisp the surface, then slice each in half or quarters. This second pass is the difference between a fish cake that snaps and one that's gone soft waiting its turn.
Step 6: Assemble
Ladle hot broth over the noodles, top with sliced fish cakes, scallions, and fried shallots, and serve with lime and chili on the side. Stir the lime in at the table — it should stay bright, not simmer into the broth.

Questions from the kitchen
What exactly are bánh canh noodles, texture-wise?
They're thick, round, and slightly translucent, made from a rice-and-tapioca dough that gives them a distinctive chew — springier and slipperier than wheat noodles, closer to Japanese udon in girth but stretchier. If you can only find udon, the soup is still delicious; just expect a softer bite and call it what it is rather than pretending it's the same dish.
Can the fish cakes be made ahead and frozen?
Yes — after the first fry, cool completely and freeze in a single layer, then bag them. Fry from frozen (a couple of minutes longer) rather than thawing first, which keeps them from going mushy at the edges.
My broth turned cloudy — what went wrong?
Either the bones weren't rinsed of blood before simmering, or the broth boiled hard instead of holding a gentle simmer. A rolling boil emulsifies fish fat into the water and turns it milky; a fish broth wants a bare, patient simmer with the foam skimmed early.
