Onion Pancakes Recipe: Crispy, Flaky Scallion Pancakes

These Chinese-style onion pancakes, usually made with scallions, are savory, pan-fried flatbreads with a crisp surface and tender, layered middle. A simple hot-water dough rolls easily, while a thin coating of oil and flour helps create flaky layers; serve them hot with a tangy soy-vinegar dip.

Ingredients

2 cups all-purpose flour (250 g), plus 2 tablespoons (16 g) for dusting the layers
⅔ cup just-boiled water (160 ml)
1 tablespoon cool water (15 ml)
¾ teaspoon fine salt (4 g), divided: ½ teaspoon (3 g) for the dough and ¼ teaspoon (1 g) for the scallions
1½ cups thinly sliced scallions (about 90 g), green and white parts
2 tablespoons neutral oil (30 ml), such as canola or sunflower oil, for the layers
2 tablespoons neutral oil (30 ml) for pan-frying, divided as needed
2 tablespoons soy sauce (30 ml)
1 tablespoon unseasoned rice vinegar (15 ml)
1 teaspoon water (5 ml)
½ teaspoon sugar (2 g)
1 teaspoon chili crisp or chili oil (5 ml), optional

Instructions

Mix the dough. Put the flour and ½ teaspoon salt in a large heatproof bowl. Pour in the just-boiled water while stirring with chopsticks or a sturdy spoon until the flour forms shaggy clumps. Stir in the cool water. When the dough is cool enough to handle, bring the clumps together with your hand. It may look uneven at this point; that is normal. The hot water partially softens the flour and makes a pliable dough without yeast.
Knead and rest. Turn the dough onto a lightly floured surface and knead for about 4 minutes, pressing and folding until it is mostly smooth. It should feel soft and slightly tacky, not wet. If it sticks heavily to your hands, dust the surface with a little flour; if it feels dry or cracks when pressed, dampen your hands and knead briefly. Shape the dough into a ball, return it to the bowl, cover, and leave it at room temperature for 30 minutes. This resting time relaxes the dough so it rolls out without springing back.
Prepare the filling and dip. While the dough rests, slice the scallions thinly and mix them with the remaining ¼ teaspoon salt. In a small bowl, stir together the soy sauce, rice vinegar, teaspoon of water, sugar, and chili crisp if using. Set aside. Measure the 2 tablespoons of layer oil and 2 tablespoons of extra flour nearby; having these ready makes shaping less messy.
Divide and roll the pancakes. Cut the rested dough into 4 equal pieces and keep the pieces you are not using covered. On a lightly floured surface, roll one piece into a thin rectangle about 8 by 10 inches (20 by 25 cm). Brush it lightly with oil, then scatter on about ½ tablespoon of the extra flour and one-quarter of the scallions, leaving a narrow border. The flour helps keep the layers distinct; avoid piling the filling too thickly, which can make the dough tear.
Coil for layers. Starting from a long edge, roll the rectangle into a snug rope. Coil the rope into a flat spiral, tuck the end underneath, and press gently. Roll the spiral into an approximately 7-inch (18-cm) round, using light, even pressure so the scallions stay inside. A few small green flecks showing through are fine. Repeat with the other dough pieces, keeping the finished rounds covered while you work. Shape all four in about 20 minutes.
Pan-fry until crisp. Heat a heavy skillet over medium heat and add a thin film of the frying oil. Cook one pancake for about 2 minutes, until the underside is golden in spots. Flip, add a little more oil around the edge if the pan looks dry, and cook the second side for about 2 minutes. Flip once more and cook briefly if needed; the pancake should be crisp outside and cooked through, with no raw, doughy band in the center. Adjust the heat down if the outside browns before the center cooks. Transfer to a wire rack or plate and repeat with the remaining pancakes, adding oil as needed. Allow about 4 minutes per pancake, or 16 minutes total.
Cut and serve. Let each pancake stand for a minute so it is easier to handle, then cut it into wedges with a sharp knife or kitchen scissors. Serve hot with the dipping sauce. If you want to keep the first pancakes warm while the rest cook, place them in a low oven, around 200°F (95°C), on a rack; do not cover them tightly, or trapped steam will soften the crust.

Tips

Use water that has just boiled, but add it carefully. Stir as you pour so the hot water spreads through the flour instead of forming one large cooked lump. Add the small measure of cool water after the first mixing; flour brands and measuring methods vary, so the dough’s feel is a more useful guide than appearance alone. A soft dough that releases from the bowl is right.
Keep the dough covered. Dough exposed to air can form a dry skin that cracks as you roll it. Cover the bowl during the full rest and keep unused portions under a clean towel or wrap while shaping. If a round resists rolling and keeps shrinking, leave it alone for 5 minutes, then continue with gentle strokes.
Use a thin, even layer of oil. Too little oil and flour can leave the layers fused; too much can make the dough slippery and difficult to roll into a coil. Brush rather than pour, and distribute the scallions evenly. If a little filling escapes, tuck it back in or leave it; a few exposed scallions will toast in the pan.
Control the pan heat and choose a substitute thoughtfully. Medium heat gives the center time to cook while the exterior browns. If you do not have scallions, use finely chopped chives for a milder flavor or a small amount of finely sliced leek for a sweeter, more substantial filling. Leek pieces should be thin so they soften during frying.

Serving Suggestions

Serve these pancakes as a snack, appetizer, or side dish alongside a Chinese-inspired meal. Their crisp edges and savory scallion filling pair well with hot-and-sour soup, a bowl of rice, stir-fried vegetables, or tofu. For a simple light meal, cut a pancake into wedges and add a cucumber salad dressed with rice vinegar and sesame oil. The dipping sauce in the recipe is salty, sour, and lightly sweet; taste it before serving and add a splash of water if you prefer a gentler dip, or a little more vinegar for sharper acidity.

For a group, cut each pancake into six or eight wedges and arrange them on a warm platter with the sauce in a small bowl. They are best soon after frying, when the surface is crisp and the layers are still tender. If serving several dishes, fry the pancakes near the end and bring them to the table promptly rather than stacking them while hot, since steam trapped between pancakes softens their crust.

Variations

Sesame version: Replace 1 teaspoon of the neutral layer oil with toasted sesame oil. Its aroma is strong, so using more can overwhelm the scallions. Sesame oil also works in the dipping sauce; add a few drops if you want a nuttier finish.

Extra onion flavor: Add 1 tablespoon (about 10 g) of very finely minced yellow onion to the scallions. Keep the pieces small and use only a little, because larger raw onion pieces can release moisture and make the pancakes harder to roll. The result is sweeter and more onion-forward than the classic scallion version.

Herb or allium swap: Finely chopped chives can replace some or all of the scallions for a more delicate flavor. A small amount of thinly sliced leek is another option, though it has a sweeter, less fresh bite. Avoid wet ingredients such as chopped tomatoes, which can make the layers soggy.

Different dipping sauce: Use black vinegar in place of rice vinegar for a deeper, malty tang, or add a pinch of toasted sesame seeds to the sauce. Black vinegar is sold in many Asian grocery stores; rice vinegar is an easy substitute with a lighter, cleaner acidity. If using seasoned rice vinegar, reduce or omit the added sugar and taste before adjusting.

Storage and Reheating

For the crispest result, serve the pancakes right away. Cool any leftovers promptly and refrigerate them within 2 hours in an airtight container, with parchment between the pancakes if stacking. They keep for 3 to 4 days in the refrigerator. The crust will soften while chilled, but reheating in a skillet brings back some crispness.

To reheat, warm a lightly oiled skillet over medium-low heat and cook the pancakes for 2 to 3 minutes per side, turning as needed until hot throughout and crisp again. For food safety, USDA FSIS recommends reheating leftovers to 165°F (74°C); check the center with a food thermometer, especially when reheating a thick stack or several portions together. A microwave will heat them quickly but tends to make the layers soft, so use it only if crispness is not important. To freeze, cool the pancakes completely, separate them with parchment, and store in a freezer-safe bag for up to 2 months. Reheat from frozen in a covered skillet over low heat until hot, then uncover and cook briefly on both sides to refresh the surface.

Frequently Asked Questions

Are onion pancakes the same as scallion pancakes?
Often, yes. In English, onion pancakes commonly refers to Chinese scallion pancakes, made with scallions folded into a layered dough. They are different from Korean pajeon, which is typically a batter-based pancake that may include scallions and other ingredients. Regional and household recipes vary, so the name can describe more than one style.

Why is my dough tough or hard to roll?
The dough may need more resting time, or it may have been kneaded with too much extra flour. Keep it covered and let a resistant piece rest for 5 minutes before rolling again. Use only a light dusting of flour on the work surface; adding a lot can make the finished pancakes dry and dense.

Why did my pancake turn brown before the middle cooked?
The pan was probably too hot, or the pancake was rolled thicker than intended. Reduce the heat to medium-low and give the next one more time, turning it as it cooks. Roll the rounds to an even thickness and avoid compressing the center into a thick mound when forming the coil.

Can I make the dough ahead?
Yes. After kneading, cover the dough tightly and refrigerate it for up to 24 hours. Let it sit at room temperature for about 20 to 30 minutes before dividing and shaping, so it is easier to roll. You can also shape the pancakes a few hours ahead, keep them covered in the refrigerator with parchment between them, and pan-fry them just before serving.

Can I make these without a dipping sauce?
Absolutely. The pancakes are seasoned with salt and scallions and can be eaten plain. You can also serve them with soy sauce, a little rice vinegar, or a store-bought chili oil. Taste any salty condiment before adding more salt to the pancake filling.

Can I use whole-wheat flour?
You can replace up to about one-quarter of the all-purpose flour with whole-wheat flour. The dough will be less elastic and the pancakes will taste heartier, so start with the listed water and add a teaspoon or two only if the dough feels dry. Replacing all the flour generally makes the dough harder to roll thin and the layers less tender.
