Sourdough Bagels at Home: A Step-by-Step Guide

A great bagel is dense, chewy, slightly crusty, and complex in flavor. Sourdough bagels add depth that yeast-only versions can't match. Here's how to make them at home.

The recipe

For 8 bagels:

• 500g bread flour (high protein, 13%+)
• 250g warm water (50% hydration — bagels are stiff)
• 100g active starter
• 25g sugar (or barley malt syrup, traditional)
• 10g salt

For the boil:

• 4 quarts water
• 30g barley malt syrup (or honey)
• 15g baking soda

For topping:

• 1 egg white + 1 tbsp water (egg wash)
• Toppings: sesame, poppy, salt, everything seasoning, etc.

Method

Mix and knead

Combine all dough ingredients. Knead 10 minutes until smooth and elastic. The dough should be very stiff.

Bulk ferment

3 hours at room temperature, or 12 hours in the fridge.

Divide

Divide into 8 equal pieces (~110g each). Round each into a tight ball.

Shape

Two methods:

Method 1 (rolled):

• Roll each ball into a 9-inch rope
• Wrap the rope around your palm
• Press the ends together at the back of your hand to seal

Method 2 (poked):

• Press your thumb through the center of each ball
• Stretch the hole to 1.5–2 inches wide
• The hole shrinks during boiling

Either works. Poked is faster; rolled is more traditional.

Cold proof

Place shaped bagels on parchment-lined sheets. Refrigerate 12–24 hours uncovered.

The cold time develops flavor and dries the surface so toppings stick.

Boil

Bring 4 quarts water to a boil with malt syrup and baking soda.

Drop bagels in 2–3 at a time. Boil 30 seconds per side.

Remove with a slotted spoon. Place on parchment-lined baking sheets.

Top

While wet, brush each bagel with egg wash. Apply toppings generously.

Bake

450°F for 18–22 minutes until deep golden brown and crusty.

The boil is essential

Boiling does several things:

• Sets the crust before baking (creates the chewy outer layer)
• Activates surface starches (creates the shine)
• Limits oven spring (keeps bagels dense)
• Adds malt flavor

Skip the boil and you have rolls, not bagels.

Why barley malt syrup

Barley malt syrup is the traditional malt that gives bagels their flavor. It adds:

• Slight sweetness
• Rich, malty depth
• Color development
• Slightly chewier crust

Honey is an acceptable substitute but the flavor is different. Try the malt syrup if you can find it.

Common mistakes

Pale, soft bagels — boil time too short, or topping issues.

Dense, brick-like bagels — fermentation too short, or kneading insufficient.

Bagels with weird shapes — shape and proof more carefully.

Toppings fall off — egg wash too thin, or applied to dry bagels (must be wet).

Bagel topping recipes

Everything seasoning

• 2 tbsp sesame seeds (white)
• 2 tbsp poppy seeds
• 1 tbsp dried minced garlic
• 1 tbsp dried minced onion
• 1 tsp coarse salt

Mix and store in a jar. Use generously on bagels.

Cinnamon raisin (in the dough)

• 1 cup raisins, soaked in warm water 30 min
• 2 tbsp cinnamon
• Add at the second fold

Cheese (after boil)

• ½ cup grated cheddar or pepper jack
• Apply after egg wash, before baking

Pumpernickel-style

• Replace 100g bread flour with 100g rye flour
• Add 2 tbsp molasses to the dough

Storing

Bagels are best within 24 hours of baking. After that, they stale fast.

For longer storage:

• Slice each bagel in half horizontally
• Stack with parchment between
• Freeze in zip-top bag

To reheat: toast directly from frozen. The toaster gives you a great bagel quickly.

Common questions

Can I skip the boil? No. It's essential for bagel texture.

Can I use yeast in addition to starter? Yes — for more reliable rise. Add 2g instant yeast.

Can I use all-purpose flour? Yes, but the bagels will be softer. Bread flour is better.

How much malt syrup is too much? A few tablespoons in the boil and 25g in the dough is the standard. More gets too sweet.

Do I need a stand mixer? No, but the dough is stiff. Hand-kneading takes 12 minutes of effort.

Variations

• Pumpernickel bagels (see above)
• Asiago cheese bagels — top with grated Asiago after boil
• Sesame Egg bagels — add 2 eggs to the dough, replace 50g water; top with sesame
• Rainbow bagels — color portions of the dough with food dye, twist together (visually fun, normal taste)

A New York-style bagel at home?

NYC bagels are famously hard to replicate at home. Reasons:

• Commercial-grade ovens with steam injection
• High-protein malted flour (sometimes proprietary blends)
• Longer cold ferments (sometimes 48+ hours)
• The water (debatable how much it matters)

You can get close at home. Long cold proof, high-protein flour, plenty of malt, and a hot oven get you 80–90% of the way there. The remaining 10–20% is the bakery's commercial advantages.

Why this is worth the effort

A NYC bagel shipped to your door is $5 each plus shipping. A homemade sourdough bagel is $0.50 each, fresh, and impressively close to the real thing.

Once you've made them once, you'll keep doing it.

A weekend bagel routine

Friday evening

• Mix dough
• Bulk 3 hours
• Refrigerate

Saturday morning

• Pull dough from fridge
• Divide and shape
• Cold proof 12 hours

Sunday morning

• Boil and bake
• Eat 4, freeze 4

Total active time: 90 minutes spread across 36 hours. You eat fresh bagels with cream cheese on Sunday morning and have 4 in the freezer for the rest of the week.
