Thai Rice Crisps (Khao Taen) with Palm Sugar

Thai rice crisps, often called khao taen or nang let, are Northern Thai-style snacks made by shaping cooked sticky rice, drying it until firm, and briefly deep-frying it until puffed and crisp. A light palm-sugar drizzle gives them a sweet finish, while the plain rice and a little salt keep each bite balanced; household versions vary in shape, seasoning, and topping.

Ingredients

2 cups (370 g) Thai glutinous rice, also called sticky rice
6 cups (1.4 L) cool water, for soaking the rice; discard after soaking
2 cups (475 ml) water, for the steamer
1/2 teaspoon (3 g) fine salt
4 cups (950 ml) neutral high-heat oil, such as canola or peanut oil, for frying; use enough to reach about 2 inches (5 cm) in your pot
1/2 cup (100 g) palm sugar, finely chopped or shaved
3 tablespoons (45 ml) water, for the syrup
1 tablespoon (9 g) white or black sesame seeds, optional

Instructions

Soak the rice. Rinse the glutinous rice in a bowl, changing the water until it looks mostly clear. Cover it with the measured cool water and soak for 6 hours at room temperature. Drain thoroughly. This long soak helps the grains steam evenly; ordinary long-grain rice will not bind or puff in the same way.
Steam until tender. Bring the steamer water to a steady simmer. Put the drained rice in a dampened steamer basket lined with cheesecloth or a clean, thin kitchen towel. Keep the rice in a fairly even layer, cover, and steam for 25 minutes. Check that the grains are tender all the way through; if the center is still firm, steam for another 5 minutes. Keep the rice above the water rather than boiling it directly, which can make it waterlogged.
Season and cool briefly. Tip the hot rice into a wide bowl and sprinkle over the salt. Fold gently with a rice paddle or spatula so the seasoning is distributed without turning the grains into paste. Leave it for about 20 minutes, until it is cool enough to handle but still slightly warm and sticky. Do not leave cooked rice sitting out for hours; shape it as soon as it is manageable.
Shape the crisps. Set parchment paper on two baking trays. Wet your hands lightly, take about 2 tablespoons of rice at a time, and press it into a compact round about 2 1/2 inches (6 cm) across and 1/4 inch (6 mm) thick. A small hole in the center helps the pieces fry evenly, though flat disks work too. Aim for an even thickness and smooth away loose grains. Make about 18 pieces, using damp hands as needed so the rice does not stick.
Dry the rice rounds. Heat the oven to 200°F (95°C). Bake the trays for 2 hours 30 minutes, turning the pieces over and rotating the trays after about 75 minutes. The exact time depends on thickness and oven airflow. They are ready when they feel dry and firm all the way through, with no damp or soft center; they should not be deeply browned. If they still bend or feel tacky, continue drying in 15-minute increments. Let the rounds cool for 10 minutes before frying.
Make the palm-sugar syrup. While the rounds finish drying, put the palm sugar and 3 tablespoons (45 ml) water in a small saucepan. Warm over medium-low heat, stirring until the sugar dissolves. Simmer gently for 3 to 5 minutes, until the syrup lightly coats a spoon, then remove it from the heat. It thickens as it cools, so do not cook it until it becomes hard or candy-like. Stir in sesame seeds if using.
Fry in small batches. Pour the oil into a heavy, deep pot so it is about 2 inches (5 cm) deep, leaving plenty of space at the top. Heat to 350°F (175°C), checking with a clip-on or instant-read thermometer. Lower in one dry rice round at a time with a spider or slotted spoon. It should puff within a few seconds; turn it once and fry just until expanded and lightly golden, usually 5 to 10 seconds total. Remove promptly to a rack set over a tray or to paper towels. Let the oil return to temperature between batches. If a piece darkens before it puffs, lower the heat slightly and check that it is completely dry.
Finish and serve. Drizzle a thin stream of palm-sugar syrup over the crisps while they are still slightly warm, or brush on a light coating. Too much syrup can make them sticky and soften their crunch. Leave them uncovered until the syrup sets, about 10 minutes, then serve. Use a small amount of syrup first; extra can be offered at the table.

Tips

Use the right rice. Thai glutinous rice is sold at many Asian groceries and online. It is also labeled sweet rice, despite not tasting sugary. If it is unavailable, sushi rice can form a disc, but it contains less of the starch that gives sticky rice crisps their characteristic cohesion and puff; expect a denser, less airy result. Regular long-grain rice is not a reliable substitute.
Drying matters more than shaping. The rounds need to be thoroughly dry before they meet hot oil. A damp middle may stay hard rather than puff, and surface moisture can make oil splatter. Drying time varies with your oven, the thickness of the rice, and humidity, so use the firm, dry texture as the cue rather than relying only on the clock.
Keep the oil steady. Fry in small batches and use a thermometer. Oil that is too cool can soak into the rice and leave it heavy; oil that is too hot can brown the outside before the center expands. Lower the pieces gently and keep your hands and face back from the pot.
Make a savory batch if you like. The salt-seasoned rice is mild enough for savory toppings. Leave off the palm-sugar syrup and serve the crisps with a dip. If you cannot find palm sugar, light brown sugar works for the drizzle, though it tastes more like molasses and less like the rounded, caramel-like flavor of palm sugar.

Serving Suggestions

Serve the crisps as a snack, a party nibble, or part of a Thai-inspired meal. Their sweet, crisp surface is a natural match for unsweetened tea, iced tea, or coffee. Set out the syrup-drizzled pieces on their own, or offer a small bowl of additional syrup for people who prefer a sweeter bite. Because the rounds are crunchy and somewhat delicate, arrange them in a single layer or stand them loosely in a basket rather than piling them high.

For a savory contrast, keep a few pieces unglazed and serve them alongside a thick chili dip, such as nam prik ong, or a roasted chile dip. These are serving ideas rather than toppings that belong to every version of khao taen; the snack is also enjoyed simply with its sweet drizzle. Add dips just before serving, since moisture quickly softens the rice. For a small dessert plate, pair a crisp with fresh mango or pineapple, keeping cut fruit separate until it is time to eat.

Variations

Watermelon-scented rice: Some versions are associated with watermelon, and regional or household recipes differ in how they use it. For a gentle variation, replace 1/4 cup (60 ml) of the steaming water with strained, unsweetened watermelon juice and use it to moisten the rice after steaming. The flavor will be subtle and the rice may take a little longer to dry. Avoid adding a large amount of juice directly to the shaped rounds, because extra liquid makes them slower to dry and less predictable in the fryer.

Sesame or coconut finish: Stir sesame seeds into the syrup, as written, or sprinkle them over the drizzle before it sets. For a different texture, finish with 2 tablespoons (10 g) of finely grated, unsweetened toasted coconut. Coconut can soften if the crisps are stored in humid conditions, so use it on pieces you plan to eat soon.

Less-sweet or savory: Use only a very thin syrup drizzle, or skip it and serve the rice rounds plain with a savory dip. You can add a pinch of extra salt to the cooked rice, but avoid wet seasonings such as soy sauce before drying; they can make the pieces difficult to dry evenly. A small amount of finely ground white pepper can be mixed into the warm rice for a mild savory note.

Different shapes: Make smaller rounds for bite-size snacks or slightly larger ones for a more substantial crisp. Keep every piece close to the same thickness, since thin edges fry before thick centers. A hole is traditional in some shapes and useful for even puffing, but it is optional; press the center gently rather than stretching or tearing the rice.

Storage and Reheating

For the best crunch, serve the crisps the day they are fried. Once fully cool and dry, store plain or syrup-finished crisps in an airtight container at room temperature for up to 2 days, away from humidity and steam. If the syrup is still tacky, allow it to set before closing the container, or separate layers with parchment. Discard pieces that have been left out where they could be contaminated, and refrigerate other cooked foods within 2 hours; refrigeration is not ideal for these crisps because moisture can make them stale.

If they soften, spread the crisps in one layer on a baking tray and warm them in a 250°F (120°C) oven for 5 to 8 minutes, then cool completely before eating. This can refresh a little of the crunch, but it will not restore a crisp that has become damp or sticky throughout. Do not reheat them in a microwave, which tends to make them chewy. Keep uncooked dried rounds in a tightly sealed container in a cool, dry cupboard for up to 1 week and fry them when needed; do not store them while they are at all soft or damp.

Frequently Asked Questions

Are Thai rice crisps the same as rice crackers?
They are a kind of rice cracker, but this recipe uses cooked sticky rice shaped into rounds, dried, and puffed by deep-frying. Packaged rice crackers may be made by other methods and can have a different texture. Khao taen and nang let are names commonly associated with this Northern Thai-style snack, though naming and recipes vary.

Can I make the rice rounds ahead?
Yes. Dry the shaped rounds completely, cool them, then store them airtight in a cool, dry place for up to 1 week before frying. If there is any softness or dampness when you open the container, dry the rounds again in the low oven until firm before frying. The cooked rice should not be left at room temperature for hours before it is dried.

Why did my rice crisps stay hard instead of puffing?
The most common reasons are rice rounds that were not fully dry, uneven thickness, or oil that was not hot enough. Check a single round first: it should puff quickly in 350°F (175°C) oil. If it does not, take it out, verify the oil temperature, and make sure the remaining rounds feel dry through the center. Very thick rounds can also fry unevenly.

Can I bake them instead of deep-frying?
Baking the shaped rounds is the drying step, not a direct replacement for frying. The brief fry is what makes these rice cakes puff and become crisp. You can experiment with an air fryer, but results depend on the appliance and may be less evenly expanded; use a small test piece and follow the appliance’s safe operating instructions rather than assuming the fried texture will be identical.

Can I use brown sugar instead of palm sugar?
Yes. Use the same 1/2 cup (100 g) measure of packed light brown sugar and the same 3 tablespoons (45 ml) of water. The drizzle will still set and taste pleasant, but it will have a stronger molasses note and lack some of palm sugar’s mellow, toffee-like character. Keep the simmer gentle so the substitute does not turn into a hard candy coating.
