Bánh Đa Nướng: Cook It Thin, Dry It, Then Toast It Again
Spread the batter thin and even, dry each sheet until it is stiff and curling, and judge the final toast by light color and sesame aroma. The crispness comes from the drying and the second heating.
In a 2016 report from Vietnam's Government E-Newspaper, people in Kẻ Sặt recalled sellers at the village market toasting raw rice sheets to order for customers. The same report describes these crackers as a simple, familiar snack and as a modest gift to bring to festivals, to someone who was ill, or to people living far away. Those memories belong to one place and one generation, but they capture the idea well: bánh đa nướng is not finished in a single cooking. The sheet is made, dried, and only later toasted into something you can snap.
This article follows one home recipe, a black sesame version made with rice flour, tapioca starch (bột năng) and coconut milk, for 4 servings. Each thin sheet cooks for only about 1–2 minutes in a pan, then dries in the sun or at low heat, and finally toasts at 180°C for 7 minutes. The recipe describes the result as fragrant with black sesame and coconut.
It is one reproducible home version, not the traditional formula of any particular village. Regional crackers from Kẻ Sặt, Quảng Lộc and Vĩnh Đức use different ingredients, and they are described below for comparison only. This recipe has not been kitchen-tested by Sekai Gohan; the amounts, times and temperatures are given exactly as the recipe states them.

Here, bánh đa nướng means a round rice cracker made from a thin rice batter sheet that is dried and then toasted. It is a different dish from Dalat's bánh tráng nướng, which is topped with egg and other ingredients and nicknamed "Vietnamese pizza." The origin of the name and the dish's history are not covered here, because the sources do not establish them.
One Name, Many Regional Crackers
There is no single national formula for bánh đa nướng. Reports on individual villages and producers describe different grains, seasonings and add-ins, while sharing the same broad sequence: spread thin, dry, toast.
The 2016 Kẻ Sặt article distinguishes a sweet dough made with sugar, gac, peanuts and sesame from a savory one in which a little salt replaces the sugar. It describes rinsing and soaking the rice for about an hour, draining and grinding it, spreading the sheets by hand, adding peanuts, drying them in the sun, and toasting them over charcoal. One local maker explains that if a sheet's thickness is uneven, it browns unevenly, leaving some patches burnt and others undercooked.
In Quảng Lộc, Quảng Bình, a family producer profiled on Vietnam Tourism's rural-tourism portal names rice and sesame as the main ingredients. The rice should be dry and fluffy, the sesame selected and cleaned, and salt and pepper go into the batter. The sheets are spread and sun-dried in a clean, airy space. The same profile records the family's shift from mostly manual work to semi-automatic equipment and a newer machine oven.
Vietnam News Agency reported in 2026 that the sesame rice cracker craft of Vĩnh Đức has been preserved for more than 300 years. That age belongs to Vĩnh Đức's craft, not to rice crackers as a whole. There, finely ground rice is mixed with garlic, pepper and black sesame, sun-dried, and grilled until crisp; the crackers are made by hand and sent to overseas Vietnamese communities.
Dalat's bánh tráng nướng looks similar in photos but is built differently. Nhan Dan describes thin rice paper brushed with butter or cooking oil, cooked on a charcoal brazier, and topped with quail egg, green onion and optional meats, sausage, cheese or chicken, then cut like pizza or rolled. The recipe in this article makes its own batter from flour, dries the sheets, and toasts them plain, with nothing on top.
Ingredients: Serves 4
All seven ingredients go into one batter.
Equipment
- Mixing bowl with a lid or cover
- Whisk
- Ladle
- Nonstick skillet
- Clean drying rack
- Oven, or a food dehydrator for drying; an air fryer can be used for the final toast
Choosing the Starch and Coconut Milk
Rice flour, black sesame and coconut milk are ordinary supermarket items. The one ingredient worth looking for by name is bột năng, which is tapioca starch, also sold as tapioca flour and made from cassava. Look for packages labeled tapioca starch or tapioca flour.
Potato starch and cornstarch are different starches. There is no tested ratio or result for swapping them in, so this recipe does not recommend them as substitutes.
Keep the rice flour plain; don't mix in other kinds of rice flour or other flours, and don't add peanuts, garlic, pepper or toppings from the regional versions. Those belong to other crackers.
Method: Choose Your Drying Route Before You Start
- Batter rest: 2 hours, covered.
- Each sheet in the pan: about 1–2 minutes.
- Drying: 1–2 days in the sun, or 55°C for 4 hours followed by 65°C for 2 hours.
- Final toast: 180°C for 7 minutes.
The number of sheets depends on how much batter goes into each ladleful, so there is no single total time. Decide on sun or low-heat drying before you mix the batter.
Lumps, Soft Sheets, Dark Spots: Fixing Problems
The most important check happens between steps 4 and 5. A sheet straight from the pan is pale and bends easily; a dried sheet is stiff and curls at the edge. Don't move on to the final toast while a sheet still flexes.
| Condition | What to look at | What to do |
|---|---|---|
| Lumps of flour in the batter | Mixing in step 1 or the re-stir in step 2 | Keep whisking until the flours dissolve, and always whisk again after the rest |
| The sheet stays white and opaque | Heat level and thickness | Keep the heat at its lowest and wait for the change to translucent rather than turning up the heat; 1–2 minutes is approximate and pans vary |
| Some patches burn while others stay pale | Uneven thickness | Tilt the pan so the batter spreads to an even thickness |
| The dried sheet is still soft and won't curl | Drying is not finished | Keep drying until stiff and curling. There is no fixed extra time; for a dehydrator, follow its manual |
| The cracker darkens too much in the final toast | Oven differences | Treat 7 minutes as a guide and watch the color toward the end; check earlier next time |
| A finished cracker has gone soft | Moisture from the air | Keep crackers dry and sealed. Re-toasting times and how long they stay good are not established here |
How to Eat It
Bánh đa nướng is eaten as it is, broken into pieces as a snack. It also goes alongside rolls and salads. Keep the cracker plain and put any accompaniments on their own plate, rather than topping the cracker the way Dalat's bánh tráng nướng is topped.
Five Ways the Dish Varies
These are comparisons between different crackers and ways of eating them, not ingredients to add to this batter. None of the regional versions comes with home quantities.
- Black sesame and coconut milk home version. The recipe in this article: rice flour, tapioca starch, coconut milk and black sesame, dried in the sun or at low heat and toasted in the oven.
- Kẻ Sặt's sweet and savory lines. A sweet dough with sugar, gac, peanuts and sesame, and a savory one with a little salt instead of sugar, dried in the sun and toasted over charcoal.
- Quảng Lộc's salt and pepper. Rice and sesame seasoned with salt and pepper, sun-dried in a clean, airy space.
- Vĩnh Đức's garlic, pepper and black sesame. Finely ground rice with garlic, pepper and black sesame, sun-dried and grilled until crisp.
- Eaten alone or alongside rolls and salads. A plain cracker on its own, or served next to other dishes. Dalat's topped bánh tráng nướng is a separate snack, not a variation of this one.
Frequently Asked Questions
Are bánh đa nướng and bánh tráng nướng the same thing?
Not in the sense used here. Nhan Dan describes Dalat's bánh tráng nướng as thin rice paper brushed with butter or oil, cooked over charcoal, and topped with quail egg, green onion and optional meats or cheese. The recipe here makes a batter from flour, cooks and dries thin sheets, and toasts them plain. How far the two names overlap in everyday Vietnamese usage is not something this article tries to settle.
What if I have no sun for drying?
Use an oven or food dehydrator at 55°C for 4 hours, then 65°C for 2 hours, until the sheets are dry and curling. Keep the two stages as given rather than combining them into one temperature or shortening them.
Can I use potato starch or cornstarch instead of bột năng?
Bột năng is tapioca starch, made from cassava, according to the DOL Dictionary. No ratio or result for replacing it with another starch has been verified, so this recipe does not recommend it.
How many crackers does this make?
The recipe gives 4 servings but does not state the number of sheets, their diameter, or how much batter goes into each ladleful. The count depends on your ladle and pan.
How long does the whole recipe take?
The recipe page lists 20 minutes of preparation and 20 minutes of cooking, but those figures leave out the 2-hour rest and the drying stage. Plan around each stage instead: 2 hours resting, about 1–2 minutes per sheet in the pan, 1–2 days of sun drying or 55°C for 4 hours followed by 65°C for 2 hours, and 7 minutes at 180°C to finish.
Should I toast the black sesame first?
The recipe adds the sesame without any toasting step, stirred into the rested batter. Toasting it beforehand would change the flavor, so this version leaves it out.
Can I use an air fryer for the final toast?
The recipe says an air fryer can use the same 180°C and 7 minutes as the oven. That setting has not been checked across different machines, so watch the color closely the first time.
How long do the crackers keep?
No storage period is given here. The recipe page gives a shelf-life claim for the dried, untoasted sheets without a food-safety basis, so that claim is not adopted. Keep finished crackers sealed in a dry place; this is general advice and not a guarantee of how long they stay safe.
What about allergens?
The batter contains sesame and coconut milk. Check product labels for allergen and shared-facility information.
