Short answer: Bánh mì chay (vegetarian banh mi) has two roots: Vietnam's long Buddhist vegetarian tradition, with its skill at making tofu, mushrooms and wheat gluten taste rich, and the 20th-century banh mi itself, born from French bread. For decades the two met mostly near pagodas and on lunar vegetarian days. In the last few years, urban demand from younger Vietnamese and international visitors has pushed vegan banh mi into branded, always-open shops in central Saigon.
Root one: a vegetarian tradition centuries older than the baguette
Long before bread arrived, Vietnam had a sophisticated vegetarian cuisine shaped by Mahayana Buddhism. Monks and nuns eat vegetarian permanently, and many lay Buddhists eat chay on particular days, most commonly the 1st and 15th of each lunar month. Some observe more days, or a whole month, depending on personal vows. This created a steady, predictable demand for food without meat or fish, and with it a professional craft: how to make plant ingredients satisfying enough that a family celebration or a funeral meal could be entirely vegetarian without anyone feeling deprived.
Huế, the former imperial capital, is often described as the heart of this tradition, with pagoda cooking that influenced households across the country. Vietnamese vegetarian cooks became known for đồ chay giả mặn, literally vegetarian food imitating savoury meat dishes: "pork" from wheat gluten, "fish" from tofu skin, "shrimp" from konjac or taro. That skill set, which already existed when banh mi was invented, is what made a convincing vegetarian banh mi possible.
Root two: bread becomes Vietnamese
Wheat bread came with French colonial rule in the second half of the 19th century. At first it was eaten the French way, but over the 20th century Vietnamese bakers and vendors adapted it: a lighter, crisper loaf suited to the climate, and fillings drawn from local cooking, such as pork roll, pickles, herbs and chili. Saigon in the 1950s is commonly cited as the period when the stuffed sandwich we now call banh mi took its recognisable street form. The word went global much later; "banh mi" was added to the Oxford English Dictionary in 2011. Our Banh Mi 101 section tells that story in more depth.
Once banh mi existed, a vegetarian version was almost inevitable. The structure of bread, spread, protein, pickle and herb is modular, and Vietnamese vegetarian cooks already had a whole pantry of meat substitutes. Replace pork roll with a gluten roll, pâté with a mushroom paste, and fish sauce with soy sauce, and the sandwich works.
The quiet decades: pagoda gates and lunar days
For most of its history, bánh mì chay was a modest, local thing. You found it at carts near pagodas, at vegetarian restaurants that sold a few sandwiches in the morning, and at ordinary stalls that switched to vegetarian fillings on mùng một and rằm. It was cheap, often cheaper than the pork version, and aimed at regulars who already knew why they were eating chay. Few of these places advertised; they did not need to.
This pattern had clear limits for anyone outside the community. Hours were short, often only breakfast. Availability depended on the lunar calendar. And at mixed stalls, the line between vegetarian and vegan was blurry, as we explain in our guide on checking whether a banh mi is truly vegan. A visiting vegan could eat well, but only with local knowledge.
What changed: four forces behind the rise
Several shifts in the 2010s and 2020s pushed vegetarian and vegan banh mi into the mainstream. We prefer to describe them as trends rather than give invented numbers, because reliable market data for this niche is scarce.
- Urban health and lifestyle choices. Many younger Vietnamese in big cities now eat plant-based meals a few days a week for health or environmental reasons, not only religious ones, creating demand outside the lunar calendar.
- International visitors. Travellers who are vegan or vegetarian at home arrive wanting to try Vietnam's most famous street food, and they search for it online in English.
- Better plant ingredients. Locally produced tofu, mushrooms and grain-based cold cuts improved in variety and consistency, and nut milks became common in cafés.
- Delivery apps and online search. A shop no longer needs a pagoda-side location to be found; a clear listing and good reviews bring customers from across the city.
From stall to system: the branded vegan shop
The newest stage is the branded vegan banh mi shop: a fixed menu, consistent recipes, standardised prices, English-friendly service and long opening hours. This model answers exactly the limits of the old pattern. A visitor arriving at midnight, or on a day that is not a lunar vegetarian day, can still get a strictly plant-based banh mi without asking a single question about fish sauce.
Bánh Mì XANH, which opened in Saigon on 20 October 2023, is a clear example. It describes itself as a premium vegan banh mi brand, belongs to the Chay 365 vegetarian restaurant group and is operated by Cleo Vietnam JSC. It runs five shops in central and southern areas of the city, all open 24/7 including Sundays and Tết: near Bến Thành Market on Lê Thị Riêng, on Nguyễn Thị Minh Khai near Đa Kao, a small grab-and-go shop on Trần Hưng Đạo, on Đề Thám in the backpacker area, and inside the Chay 365 restaurant on Bùi Văn Ba in Tân Thuận ward (former District 7). According to the brand, many of its shops serve more international customers than local ones, which says a lot about who was underserved before.

What the modern vegan banh mi tastes like
The newer shops did not reinvent the sandwich; they tightened it. Fillings lean on the same pillars as pagoda cooking, namely tofu, mushrooms and grain-based cold cuts, but with more attention to contrast: crisp-edged spicy tofu next to cool pickles, a richer eggless spread, a more generous build. Some offer sweet options too, such as the butter-sugar style Vietnamese children grew up with. Drinks have followed the same path, with nut-milk coffee and nut-milk bubble tea replacing condensed milk, so a full breakfast or late-night snack can stay plant-based.
Prices are higher than at a pagoda cart, which is fair: rent in central Saigon, 24-hour staffing and imported or specialised ingredients cost money. As a reference, Bánh Mì XANH lists sandwiches from 28,000đ for the sweet Bơ Đường to 75,000đ for the large Thượng Hạng Premium.
Where to find both versions as a visitor
The best trip includes both worlds. In the morning, look for vegetarian restaurants and stalls near pagodas, where bánh mì chay sells alongside sticky rice and noodle soups; arrive early, as many sell out before late morning. On the 1st and 15th lunar days, ordinary neighbourhoods offer more vegetarian food than usual. For late nights, airport arrivals or any time you want zero ambiguity, a 24/7 fully vegan shop is the dependable choice. For area-by-area ideas, our Saigon Food Guide covers Bến Thành, Đa Kao and the Đề Thám–Bùi Viện area.

Why do Vietnamese people eat vegetarian on certain days?
Many lay Buddhists eat vegetarian on the 1st and 15th days of the lunar month as a religious practice. Some observe more days. This tradition created a long-standing market for meat-free food.
Is vegan banh mi more expensive than pork banh mi?
At traditional stalls it is often similar or cheaper. At branded shops in central Saigon it costs more, typically around 50,000 to 80,000 VND, reflecting rent, staffing and ingredients.

Which city has the strongest vegetarian food tradition in Vietnam?
Huế is widely known for its pagoda-influenced vegetarian cooking. Saigon and Hanoi have the largest number of vegetarian restaurants simply because they are the biggest cities.
