Hai Phong crab spring rolls: order one square roll or a bun cha set?

A Hai Phong crab spring roll is usually cut into four pieces before it reaches your table, but the price is for the entire roll. It’s an easy detail to miss, especially when each large, square roll can weigh nearly 200 grams before frying. A first try needs only one roll, some rice vermicelli, and a handful of fresh herbs.

What are Hai Phong crab spring rolls?

Known locally as nem cua bể, nem vuông, or nem vuông cua bể, these square crab spring rolls are one of Hai Phong’s best-loved specialties. They have a crisp, golden wrapper made from Vietnamese rice paper, filled with a savory mixture of sea crab, shrimp, pork, glass noodles, mushrooms, and vegetables.

Their shape is the first thing that catches your eye. Unlike the long, cylindrical fried spring rolls commonly found across Vietnam, Hai Phong’s version is folded into a thick square, roughly the size of an adult’s palm. From the outside, it almost resembles a small savory pastry, but cutting through the crust reveals a generous seafood filling.

Crab meat gives the dish its distinctive flavor. Traditional makers often use fresh sea crabs, steaming or boiling them just until cooked before carefully removing the meat by hand. Crabs may come from coastal areas around Hai Phong, including Do Son, Cat Ba, Trang Cat, and neighboring fishing grounds.

Some cooks particularly favor female crabs with roe, which add extra richness to the filling. Even so, the type of crab and amount of crab meat vary between establishments.

You’ll also find restaurants using fresh swimming crab, known locally as ghẹ, instead of other types of sea crab. That’s one reason two dishes both called nem cua bể can taste surprisingly different.

What’s inside a Hai Phong crab spring roll?

The filling: crab, shrimp, pork, and vegetables

A traditional Hai Phong crab spring roll usually contains:

• Fresh sea crab meat, steamed or boiled and carefully picked from the shell.
• Peeled shrimp, chopped or left in small pieces.
• Ground lean pork, adding richness and helping bind the filling.
• Glass noodles, cut into short lengths.
• Shiitake mushrooms and wood ear mushrooms.
• Bean sprouts, eggs, and black pepper.
• Kohlrabi, carrots, or other vegetables, depending on the recipe.

When you cut one open, you’ll notice strands of glass noodles mixed with white crab meat, shrimp, and dark pieces of wood ear mushroom. The filling isn’t blended into a smooth paste. Instead, you can still distinguish the softness of the seafood, the slightly chewy noodles, and the pleasantly crunchy mushrooms.

In rolls with visible pieces of crab, a slower bite brings out the crab’s own sweetness over the seasoned ground meat.

At some long-established eateries, the ingredients are prepared separately and arranged in layers before wrapping. This helps limit excess moisture, protects the delicate wrapper, and allows the roll to hold its square shape during frying.

Why are Hai Phong crab spring rolls square?

The wrapper is generally made from thin Vietnamese spring roll sheets, sometimes using freshly handmade rice paper.

These sheets are flexible enough to surround a fairly generous portion of filling without tearing. Once fried, they develop a crisp surface with multiple folded layers.

Some restaurants use two layers of rice paper for each roll. Thuan Yen, for example, has traditionally used handmade wrappers from Hang Kenh, an area of Hai Phong known for its rice paper production.

The square folds create four corners and several especially crispy edges. Combined with careful filling preparation and frying, this shape helps the roll maintain its texture despite being considerably thicker than an ordinary spring roll.

Crab spring rolls can also be wrapped into long cylinders, but the square version is by far the most recognizable in Hai Phong.

How are Hai Phong crab spring rolls different from Hanoi spring rolls?

Hai Phong’s large square version and the Vietnamese fried spring rolls, or nem rán, that many visitors already know are both fried spring rolls. Their fillings, sizes, and serving styles differ.

The crab is where they part ways: it’s optional in Hanoi-style fried spring rolls, while sea crab or swimming crab is the defining ingredient in Hai Phong’s nem cua bể.

The larger square rolls need more careful frying so the filling cooks through without burning the outside.

What do you eat with Hai Phong crab spring rolls?

A typical serving includes freshly fried crab spring rolls, rice vermicelli, fresh herbs, and a bowl of sweet-and-sour fish sauce.

The cook usually cuts each square roll into four large pieces with scissors, revealing the crab, shrimp, mushrooms, and noodles inside. The pieces may be served on their own plate or alongside the vermicelli, depending on the restaurant.

The herb plate usually holds lettuce, Vietnamese perilla, coriander, Vietnamese balm or other local herbs, and sometimes sliced cucumber.

The dipping sauce deserves just as much attention as the roll itself.

It’s usually a mixture of fish sauce, sugar, vinegar or lime juice, garlic, and chili, creating a balance of salty, sweet, and sour flavors. Thinly sliced green papaya, carrots, or cucumber may be added for extra crunch.

To eat it the local way, pick up a little vermicelli and some herbs, add a piece of crab spring roll, and dip it into the sauce.

The noodles and vegetables balance the richness of the seafood filling.

Take the first bite of spring roll on its own, without sauce, and the crisp wrapper stands apart from the sweet, savory filling.

Every restaurant has its own dipping sauce recipe, and some versions are sweeter or spicier than others. For a milder meal, simply ask:

"Cho mình để ớt riêng nhé." - Please put the chili on the side.

Bun cha with crab spring rolls: a local Hai Phong breakfast

Crab spring rolls are also served at bún chả restaurants, many of which open early in the morning.

Here diners eat them with grilled pork, rice vermicelli, fresh herbs, and dipping sauce.

A typical meal includes soft rice noodles, smoky grilled pork, crisp crab spring rolls, a plate of greens, and a bowl of sweet-and-sour fish sauce.

The lightly charred pork adds a different kind of richness, while the fried crab roll brings crunch and a seafood flavor.

Check before ordering: each restaurant serves bun cha with crab spring rolls its own way.

This combination suits a late breakfast or lunch. Doors open around 6-7 a.m. at some restaurants, though the busiest period is often between 11 a.m. and 2 p.m.

How much do Hai Phong crab spring rolls cost in 2026?

The price depends on the size, seafood content, and whether the restaurant charges by individual roll or complete meal.

Large square rolls made with fresh crab are generally more expensive than smaller spring rolls served alongside bun cha.

Approximate prices for 2026:

At Thuan Yen, a large roll went for around VND 70,000-80,000 in 2026.

Smaller eateries and market stalls sometimes sell different-sized rolls at lower prices.

Treat these as ballpark figures; each restaurant’s menu may differ a little.

How many crab spring rolls should one person order?

For a first-time visitor, one large square roll cut into four pieces, with vermicelli and herbs, is usually enough for a satisfying meal.

People with bigger appetites may order more. Regular customers sometimes eat two or even three rolls, although the generous pork and seafood filling makes them quite substantial.

Two people exploring Hai Phong’s street food should order one roll to share first. That leaves room for other local favorites later.

A group of four could start with two large rolls, cut into eight pieces, before deciding whether to order more.

Other streets and markets for crab spring rolls

Beyond these three restaurants, several parts of Hai Phong are worth exploring:

• 323 To Hieu Street: A well-known address for bun cha with crab spring rolls, but ask ahead whether it’s still serving.
• Cau Dat Street: An area with long-established local eateries, some serving traditional Hai Phong dishes.
• Cat Bi Market: A popular food market with a variety of affordable local specialties.
• Cat Cut Street, To Hieu Street, and Co Dao Market: Convenient areas to look for both individual crab spring rolls and bun cha combinations.

Market stalls often offer lower prices than full-service restaurants, but their spring rolls may differ in size and crab content.

Compare the actual rolls, not just the menu prices.

How to order Hai Phong crab spring rolls without confusing portions

Ordering a set meal? Confirm whether the price includes an entire crab spring roll or just a smaller portion, and whether rice vermicelli and grilled pork are included.

Buying Hai Phong crab spring rolls to take home

Fried crab spring rolls: best eaten the same day

Many established restaurants sell freshly fried crab spring rolls for takeaway.

The rolls are usually drained of excess oil, placed on absorbent paper, and packed in a takeaway container. Dipping sauce and vegetables are best kept in separate packages.

As fried rolls sit in a closed container, steam and moisture from the filling gradually soften the crispy rice paper. Even a carefully prepared roll won’t have quite the same crunch after several hours.

Fried crab spring rolls are best bought for eating shortly afterward, not for a long journey.

Cooked spring rolls should not sit at room temperature for more than two hours, or more than one hour when the surrounding temperature exceeds approximately 32°C (90°F).

On longer journeys, cool the food promptly and keep it refrigerated.

Frozen uncooked rolls: better for cooking at home

Some Hai Phong producers also sell uncooked crab spring rolls that have been individually wrapped, packaged, and frozen.

These are useful for visitors buying several boxes or hoping to enjoy the dish after returning home.

When prepared correctly, freshly frying uncooked frozen rolls generally produces a better crust than reheating rolls that were already fried.

Before purchasing, ask the seller:

• Are the rolls fully frozen or simply chilled?
• How many rolls are in each box, and how much does each one weigh?
• What storage temperature and expiry date are printed on the label?
• Should the rolls be thawed before frying or cooked directly from frozen?
• Can the producer provide suitable insulated packaging for a longer journey?

Shelf life on frozen roll labels runs from approximately two months at some producers to up to six months from the production date at others.

Go by the date and instructions on the package you buy.

Frozen rolls should generally remain at around -18°C (0°F), unless the packaging specifies otherwise. Once thawed, handle them according to the producer’s instructions and never leave them sitting at room temperature for hours.

How to fry frozen crab spring rolls

Use enough oil to cover the rolls or cook all sides evenly, over moderate heat.

Turn the rolls carefully as they cook.

Some producers suggest frying for around 10 minutes, but the actual cooking time depends on the size of the rolls, whether they are frozen, and the oil temperature.

The filling must be thoroughly cooked all the way to the center, particularly because it contains pork. The wrapper can turn golden before the center is done.

Contacting the restaurant at least a day in advance for larger takeaway orders gives them time to prepare and pack the rolls.

Can you bring Hai Phong crab spring rolls on a plane?

Crab spring rolls may be carried on some domestic flights within Vietnam, provided they meet the airline’s baggage, food safety, and packaging requirements.

International flights are more complicated because the destination country’s food import and quarantine regulations also apply.

Domestic flights: packaging matters

Vietnam Airlines generally permits ordinary food items within the applicable baggage weight, size, and piece limits, although strong-smelling products are subject to additional restrictions.

To pack crab spring rolls for a flight:

1. Place the rolls in sturdy, food-safe containers to prevent crushing.
2. Wrap the containers in leak-resistant bags and protective packaging.
3. For frozen rolls, use an insulated container and an airline-approved cooling method that maintains a safe storage temperature.
4. Pack dipping sauce separately in tightly sealed containers.
5. Confirm the airline’s rules for perishable food and cooling materials before departure.

Vietnam Airlines has specific restrictions on fish sauce and other strong-smelling liquids, including a maximum allowance of 3 liters or 3 kilograms per passenger under its applicable policy.

Plastic bottles must be tightly sealed, taped, and packed in a secure foam container as required by the airline.

The carrier recommends placing strong-smelling items in checked baggage and does not accept such items on ATR72-operated flights.

Vietjet’s conditions of carriage also address the transportation of fresh or frozen meat and seafood, subject to appropriate leakproof packaging, inspection, and airline acceptance.

The airline may refuse packages that do not meet its requirements.

Crab spring rolls contain several perishable ingredients, so the rules for dry snacks don’t cover them; check with your operating airline.

International flights: can you bring crab spring rolls overseas?

An airline accepting food on board says nothing about whether another country will let it in.

Crab spring rolls commonly contain pork, crab, shrimp, and eggs. These ingredients may be regulated as animal products even when fully cooked or frozen.

Rules at some popular destinations:

For travelers returning to the United States, Europe, or Australia, fried or frozen crab spring rolls are unlikely to make it past the border: the pork alone may place the product in a restricted or prohibited category.

Dipping sauce is also subject to international aviation security rules. Carry-on liquids are commonly limited to containers of no more than 100 ml, packed within the applicable one-liter liquid allowance.

Before purchasing food to take overseas, check the destination country’s customs and animal quarantine regulations.

Where declarations are required, declare the food honestly, even when carrying only a small amount.

How long do Hai Phong crab spring rolls last?

Storage time depends on whether the rolls are cooked or uncooked and how consistently they have been kept at a safe temperature.

Reheat cooked rolls from the refrigerator until the filling is hot all the way through.

An oven or air fryer can help restore some crispness to the wrapper, but the heating time must be long enough to warm the center properly.

Discard rolls that develop an unusual sour smell, a slimy texture, visible mold, or that have been left outside refrigeration for too long.

Unsafe food can smell and look normal, so go by storage time and temperature, not smell.

Who should be careful about the ingredients?

Hai Phong crab spring rolls contain several animal-derived ingredients, so travelers with food allergies or specific dietary requirements should check the recipe before ordering.

Common allergens and restricted ingredients include:

• Crab and shrimp: Both are crustacean shellfish.
• Eggs: Often used to bind the filling.
• Pork: A common ingredient in the filling.
• Fish sauce: Usually contains fish.
• Wheat: Some spring roll wrappers may contain wheat flour alongside rice flour or tapioca starch.

Traditional crab spring rolls are not suitable for vegetarians or people avoiding pork.

Travelers following a halal diet should not assume the dish is suitable simply because seafood is a prominent ingredient.

People with celiac disease or who must avoid gluten should ask specifically about the wrapper ingredients and the possibility of cross-contact during preparation.

Useful English questions include "Does this contain pork?" and "I’m allergic to shellfish."

Mention any serious allergy before you order.

When eating crab spring rolls at a restaurant, try dipping the exposed filling into the sauce first, rather than soaking the entire piece. The wrapper stays crisp, and the crab meat picks up a little of the sweet-and-sour sauce.
