Short answer
A bialy is a round, chewy yeast roll with a hollow dimple in the centre filled with toasted onion and poppy seeds. Unlike a bagel it is baked without boiling and has no hole.
A bialy is a round, chewy yeast roll with a shallow depression in the centre, filled with cooked onion and poppy seeds and baked rather than boiled. A bialy has no hole, which separates it from a bagel, and its crust is softer and flatter. This guide explains the roll, its history and how to eat and keep it.
What is a bialy?
A bialy is a baked Polish-Jewish roll, also called a bialystoker kuchen, with a dimpled centre filled with onion. The name comes from Bialystok, a city in north-eastern Poland.
The dough is a simple yeast dough of flour, water, salt and yeast. Bakers press a hollow into each piece, fill it with onion and poppy seeds and bake it. The result is soft in the middle, slightly crisp at the edges and chewy overall.
What is the difference between a bialy and a bagel?
A bialy is baked directly, has a pressed dimple and an onion filling, while a bagel is boiled before baking and has a hole through the centre.
| Feature | Bialy | Bagel |
|---|---|---|
| Cooking | Baked only | Boiled, then baked |
| Centre | Dimple filled with onion | Hole |
| Crust | Thin, soft, light | Shiny, thicker, chewy |
| Shape | Flat round | Ring |
| Toppings baked in | Onion, poppy seeds | Seeds, salt, garlic |
Boiling gives a bagel its glossy, dense crust. Without that step, a bialy has a lighter bite and bakes faster.
What is in a bialy?
A bialy contains bread flour, water, yeast, salt and a filling of onion and poppy seeds. Some recipes add a little oil or sugar to the dough.
The filling is made by cooking finely chopped onion in oil until soft and lightly golden, then mixing it with poppy seeds and a pinch of salt. Some bakers add breadcrumbs to hold moisture. Keep the onion dry, because wet filling makes the centre soggy.
How do you make a bialy at home?
Make a bialy by mixing a lean dough, proofing it, shaping flat rounds, pressing a dimple, filling it with onion and baking at a high heat.
- Mix 500 g of bread flour, 10 g of salt, 5 g of yeast and 330 ml of water, then knead for 10 minutes.
- Let the dough rise for about 1 hour, until doubled.
- Divide into eight pieces and shape them into balls.
- Flatten each ball into a 10 centimetre disc and let it rest for 30 minutes.
- Press the centre hard with your fingers to form a thin dimple.
- Fill with a teaspoon of cooked onion and poppy seeds.
- Bake at 230 degrees Celsius for 12 to 15 minutes, until the edges are golden.
Preheating a baking stone or tray helps the base crisp quickly.
How do you eat a bialy?
Most people split a bialy and toast it, then add butter or cream cheese. Fresh bialys can also be eaten plain, warm from the oven.
- Toasted with butter: the standard serving.
- With cream cheese and smoked fish: a deli-style sandwich.
- With scrambled eggs: a breakfast plate.
- With tomato and olive oil: a lighter, Mediterranean-style topping.
A bialy is best on the day it is baked. After that, toasting restores the crisp texture.
How do you store a bialy?
Store bialys in a paper bag for one day or freeze them for up to three months. They go stale faster than bagels because of the thin crust.
For freezing, cool the rolls, wrap them tightly and place them in a freezer bag. Reheat from frozen in a 175 degree Celsius oven for about 8 minutes, or split and toast them. Avoid the fridge, which dries the crumb.
Where does the bialy come from?
The bialy comes from Bialystok in north-eastern Poland, where Jewish bakers made the roll, and it reached New York with emigrants in the early 20th century. Detailed origin stories vary, so treat them as folklore rather than record.
The roll was once a daily bread in Bialystok’s Jewish community, and the city’s name became the name of the roll. Today, bialys are best known in New York, and the roll is also found in Chicago and a few other North American cities. Montréal is better known for its bagels, and the bialy is much rarer there.
What other names does the bialy have?
The bialy is also called a bialystoker kuchen, a bialystok roll or simply a bialy, with the plural bialys or bialies. All the names refer to the same dimpled, onion-filled roll.
| Name | Where it is used |
|---|---|
| Bialy | The common English short form |
| Bialystoker kuchen | The fuller Yiddish-English name |
| Bialystok roll | A descriptive name used by some bakers |
| Cebularz | The Polish onion roll, a close relative from the Lublin region |
The Polish cebularz is a similar flat bread with onion and poppy seeds, but it is usually larger and softer than the New York bialy.
What can you use instead of a bialy?
A toasted English muffin, a small flat roll or a thin bagel are the closest substitutes for a bialy, though none has the onion-filled dimple. A homemade roll topped with cooked onion works best.
Press the dimple into plain dinner rolls before baking and fill with onion and poppy seeds. This gives the flavour without making a full bialy dough. For sandwiches, a flat roll sliced in half works the same way.
What are the common mistakes with bialys?
The common mistakes are using wet onion filling, pressing the dimple too lightly and baking at too low a heat. Each makes the roll doughy or puffy.
- Wet filling: cook the onion until dry before filling.
- Shallow dimple: press until the dough in the centre is thin.
- Low oven: use a hot oven so the edge sets before the centre rises.
- Over-proofing: shaped rounds that rise too long lose their shape.

Common questions
Where does the bialy come from?
The bialy is named after the Polish city of Bialystok, where Jewish bakers made the roll. It later became a staple of New York bakeries. Origin stories vary, so treat exact details as folklore.
Is a bialy smaller than a bagel?
Usually yes. A bialy is a flat round about 10 centimetres across and lighter in the hand than a bagel, because it is not boiled and has no thick, dense ring. Sizes vary by baker.
Should a bialy be toasted?
Yes, most people split and toast a bialy, especially a day old, because the crust softens in storage. Spread with butter or cream cheese. Fresh from the oven, many eat it plain.
Can you freeze bialys?
Yes. Freeze them whole or split in a freezer bag for up to three months. Thaw for an hour and toast, or reheat in a 175 degree Celsius oven for about 8 minutes until the crust crisps.
What goes on a bialy?
The classic filling is cooked onion and poppy seeds, baked into the centre. Eaters add butter, cream cheese, smoked fish or tomato slices. The dimple holds toppings in place.
