Vietnamese-American Cooking — Pho, Banh Mi, and the Refugee Cookbook Boom

The arrival

Vietnamese immigration to the US is overwhelmingly post-1975. The fall of Saigon triggered a refugee diaspora, primarily to Southern California (Westminster's Little Saigon is the largest concentration outside Vietnam), Houston, the DC suburbs, San Jose, and New Orleans (the latter has a substantial Vietnamese-American shrimping community in Versailles and other Gulf Coast parishes).

The cuisine they brought is a regionally varied one. North Vietnamese (Hanoi) cooking — pho, bun cha, herbal, lighter spicing. Central Vietnamese (Hue) cooking — imperial, refined, spicier. South Vietnamese (Saigon) cooking — sweeter, more fish sauce-forward, the basis of most American Vietnamese restaurants.

What's on the menu

Pho. The northern Vietnamese beef noodle soup, slow-simmered, aromatic with star anise, cinnamon, and charred onion and ginger. Pho ga (chicken) is the lighter sibling.
Banh mi. The colonial-era French baguette filled with Vietnamese cha lua (steamed pork sausage), pickled daikon and carrot, cilantro, cucumber, chile. The sandwich is younger than the pho; it traveled to the US in the 1980s and is now ubiquitous.
Goi cuon (summer rolls). Rice paper, shrimp, pork, herbs, vermicelli. Cold, fresh, dipped in peanut-hoisin sauce.
Bun bo Hue. Spicy beef noodle soup from central Vietnam — lemongrass, shrimp paste, chile oil. The fiery cousin to pho.
Com tam. Broken rice with grilled pork chop, egg, pickles. A Saigon working-class breakfast that became a flagship of Vietnamese-American restaurant menus.

The "is pho Vietnamese or French" question

It is Vietnamese. Pho draws on Vietnamese broth-making technique. The French colonial period influenced it (Vietnamese beef butchery patterns came from French slaughtering practices, and pho's name may relate to pot-au-feu), but the dish itself is Hanoi, early 20th century, Vietnamese.

The banh mi is a clearer case of French-Vietnamese fusion. The baguette is a French colonial bread style; the filling is Vietnamese. The sandwich is unambiguously a Vietnamese invention using a French bread vehicle.

What to cook to start

Andrea Nguyen's pho bo from The Pho Cookbook. Plan for half a day. The broth is the dish; nothing else compensates if the broth is wrong.
Goi cuon — 30 minutes, no cooking once the shrimp is poached.
Banh mi at home — buy a baguette, pickle daikon-and-carrot the day before, grill some chicken or pork, assemble.

Reading and watching

Anthony Bourdain: No Reservations — the Vietnam episodes are still some of the best food television about the cuisine.

The migration

Vietnamese immigration to the United States was triggered primarily
by the end of the Vietnam War in 1975. The first wave (1975) was
roughly 130,000 refugees, evacuated through Operation Frequent
Wind and subsequent military and civilian efforts. The second wave
(1978 to 1990) was the boat-people exodus, with hundreds of
thousands of Vietnamese refugees arriving via Southeast Asian
refugee camps.

The community settled densely in southern California (Orange
County's Little Saigon is the largest Vietnamese diaspora community
outside Vietnam), Houston, San Jose, and Northern Virginia. By
2000 the US Vietnamese-American population was roughly 1.2 million;
contemporary estimates are around 2 million.

The food infrastructure

The Vietnamese-American food infrastructure built rapidly in the
1980s and 1990s. The wave of restaurants in Orange County and San
Jose established the contemporary American familiarity with pho,
banh mi, and the broader Vietnamese cuisine.

Andrea Nguyen's writing — Into the Vietnamese Kitchen (2006),
The Pho Cookbook (2017), Vietnamese Food Any Day (2019) — has
been the major English-language reference for the cuisine. Diana
Wuy and Helen Le have built large YouTube followings for home
cooking instruction.

The dishes

The Vietnamese-American canon as it stands:

Pho. The beef noodle soup. The Northern (Hanoi-style) version
is clean-broth; the Southern (Saigon-style) version is more
garnish-heavy with bean sprouts, basil, hoisin, sriracha. Both
exist in the US; the Southern style dominates the diaspora.
Banh mi. The sandwich on a baguette (French colonial
inheritance) with pâté, mayonnaise, pickled vegetables, cilantro,
jalapeño, and roasted meat or tofu.
Goi cuon (summer rolls). Rice-paper rolls with shrimp, pork,
herbs, vermicelli.
Bun bo Hue. The spicy beef noodle soup from central Vietnam.
Com tam. Broken-rice plate with grilled pork.

The refugee cookbook boom

The 2010s and 2020s have produced a substantial wave of
Vietnamese-American cookbooks that frame the cuisine through the
refugee experience. These include:

Andrea Nguyen's continued bibliography.
Andy Ricker, Pok Pok Noodles (2012) and the Pok Pok restaurant
group — Ricker is not Vietnamese but his Thai cuisine work has
been important.
Charles Phan, Vietnamese Home Cooking (2012) and the Slanted
Door restaurant group.
More recently, second-generation Vietnamese-American chefs
(Diep Tran, Tu David Phu, others) writing memoirs of food and
family.

The pattern is consistent across the genre: food as a vehicle for
preserving and transmitting refugee history.

The contemporary scene

Vietnamese restaurants in the US span a spectrum from the modest
neighborhood pho shop (typically $12 to $18 per bowl) to the
high-end Vietnamese tasting-menu format pioneered by Charles Phan
and continued by The Slanted Door's various Bay Area successors.

The home-cooking tradition is also active. Vietnamese-American
families maintain food practice across generations; the
Lunar New Year (Tet) celebrations remain anchored in specific
home-cooked dishes.
