Bún thang
Hanoi's day-after-Tết bowl — a crystal chicken broth over knife-fine threads of egg crepe, chicken, and giò lụa, laid out with a surveyor's patience.

Bún thang is what Hanoi does with abundance: it takes the leftovers of Tết — the boiled chicken, the giò lụa, the dried shrimp from the pantry — and disciplines them into the most exacting bowl in the northern repertoire. The dish as we know it was polished in the early twentieth century, in the era of Hanoi's great phở flowering, and old cookbooks treat it as a measure of a household's refinement. The name is argued over — soup, medicine dose, ladder — and the arguments are half the fun. What is not argued is the standard: clear broth, and everything on it cut fine.
This is knife work as devotion. Every topping is cut to the width of the noodle — egg crepe, chicken, giò lụa, all in threads, arranged in sectors so the finished bowl looks like a compass rose until the broth arrives. There is no searing, no caramel, nothing to hide behind; the cooking is gentle and the precision is the flavor. Make it once with full attention and you will understand why Hanoians serve it to the guests they most want to impress — and why they check the width of your egg threads when you do.
Sharpen your knife before you start, not during. Every thread in this bowl is a knife cut, and the difference between fine and ragged is the difference between bún thang and chicken soup with toppings.

Serves 4
Broth
- 1.2 kgchicken, whole or bone-in pieces — about 2.5 lb
- 30 gdried shrimp — about 1/3 cup — rinsed; these and the chicken are the broth's two voices
- 1dried squid — optional but traditional; toasted over a flame first. Skip it before you substitute it
- 2shallots — charred and peeled
- 20 gfresh ginger — a thumb, charred
- 15 grock sugar — about 1 tbsp
- 30 mlfish sauce — 2 tbsp, plus more to season
- 2.5 Lwater — about 10 cups
The threads
- 3eggs — beaten with a pinch of salt for paper-thin crepes
- 200 ggiò lụa (Vietnamese pork sausage) — 7 oz — sold in Vietnamese markets, often labeled "pork roll" or chả lụa
- As neededthe poached chicken, breast and thigh — torn along the grain, then cut fine
To serve
- 400 gthin rice vermicelli (bún) — 14 oz dried; the finest gauge you can find
- 1 bunchrau răm (Vietnamese coriander) — cut into ribbons; scallion greens alongside
- 1 tspmắm tôm (fermented shrimp paste) — optional — a fingertip dab per bowl, stirred in at the table
- 4lime wedges
Methodcách làm
Step 1: Build a broth worth seeing through
Poach the chicken in the water with the charred shallots and ginger at a bare shiver, skimming relentlessly. Pull the bird when just cooked, about 35 minutes, then return the carcass with the dried shrimp, toasted squid, rock sugar, and fish sauce for another 45 minutes. Strain through cloth — this broth is served in a wide bowl with nowhere to hide.
Step 2: Make the egg crepes
Wipe a nonstick pan with an oiled paper towel over medium-low heat and pour in just enough egg to film the surface, tilting fast. Cook each crepe until barely set, without color — browning would put a flavor in the bowl that doesn't belong to it. Stack and cool.
Step 3: Cut everything to thread
Roll the crepes and slice them into threads no wider than the bún. Cut the giò lụa into fine matchsticks; tear the chicken along its grain and cut it to match. Uniformity is not fuss here — it is the dish. Every spoonful should carry all three, and that only happens at one width.
Step 4: Compose the bowls
Mound cooked bún in each bowl, then lay the chicken, egg, and giò lụa in separate neat sectors like a compass rose, with rau răm and scallion at the center. The bowl is presented before the broth goes in — the diner should see the work once.
Step 5: Ladle and finish
Bring the seasoned broth back to a full boil and ladle it gently down the side of each bowl so the sectors hold. Offer lime and the dab of mắm tôm at the table — it reads as a threat and lands as depth.

Questions from the kitchen
What does "thang" actually mean?
It's debated. The tidy explanation reads it as the Sino-Vietnamese word for soup or for a dose of medicine — a bowl of restoration; another story says it refers to a ladder, for the layered arrangement. Hanoi tellers pick whichever suits the evening. Nobody disputes the bowl itself.
Is this really a leftovers dish?
In origin, yes — the days after Tết left northern kitchens with boiled chicken and half a roll of giò lụa, and bún thang turned that surplus into the most disciplined bowl of the year. Making it from scratch, as here, is the modern penalty for not having a Tết feast to raid.
I can't find giò lụa. What then?
A good-quality mortadella, cut fine, is the honest stand-in — same family of smooth pork emulsion, slightly louder seasoning. It costs you some delicacy but keeps the third voice in the bowl. Omitting it entirely thins the chord more than you'd think.
