Sourdough Bagels: Chewy, Shiny, and Easier Than You Think

Real New York bagels are made by boiling the dough before baking. That step is what gives bagels their signature chewy interior and shiny, blistered crust. Sourdough bagels combine that classic technique with the flavor and digestibility of wild fermentation. The result is a bagel that is denser than a baguette, more flavorful than a commercial bagel, and surprisingly easy to make at home.

Why Are Sourdough Bagels Different?

A traditional New York bagel uses commercial yeast, a high-protein flour, and a short fermentation. Sourdough bagels use a longer, cooler fermentation that develops the same lactic tang you get in sourdough bread. The longer ferment also breaks down more of the gluten, which makes bagels easier to digest than their commercial cousins.

The key technique is unchanged: high-protein dough, shaped into rings, briefly boiled in alkaline water (baking soda or malt), then baked at high heat. The boiling step is what gives bagels their distinctive chewy texture and glossy crust. Skipping the boil is a common mistake that produces a bread roll, not a bagel.

What Is the Best Sourdough Bagel Recipe?

This is a stiff, 55% hydration dough. Bagels need less water than other breads because the dough has to hold its shape when shaped and when boiled. Use bread flour or high-gluten flour for the chewiest result.

Bakers percentages:

• High-gluten or bread flour: 100%
• Water: 55%
• Active sourdough starter: 15%
• Salt: 2.2%
• Barley malt syrup or sugar: 4%

For 500g flour (8 bagels):

• High-gluten or bread flour: 500g
• Water (warm, 80F): 275g
• Active sourdough starter: 75g
• Sea salt: 11g
• Barley malt syrup (or brown sugar): 20g

How Do You Make Sourdough Bagels?

Step 1: Mix (10 minutes)

Dissolve salt and malt in water. Add starter and mix by hand until broken up. Add flour and mix until a stiff, smooth dough forms. The dough will feel much firmer than other sourdough doughs. Cover and rest 20 minutes.

Step 2: Bulk Ferment (2-3 hours at 75F)

Bagels need a shorter bulk than other breads because they are denser and need to hold their shape. Leave at room temperature 2-3 hours, until risen by about 50%.

Step 3: Divide and Shape (15 minutes)

Turn the dough onto a clean counter. Divide into 8 equal pieces (about 110g each). Shape each into a smooth ball, then poke a floured finger through the center to make a hole. Stretch the hole to about 1.5 inches wide. The bagels will shrink during baking, so make the hole slightly larger than you want it.

Step 4: Cold Proof (12-16 hours)

Place shaped bagels on a parchment-lined sheet pan, cover with plastic wrap or a damp towel, and refrigerate overnight. The cold proof firms up the bagels, making them easier to boil without deflating.

Step 5: Boil (1 minute per side)

Preheat oven to 450F. Bring a large pot of water to a boil. Add 1 tablespoon of baking soda or malt syrup (this alkalizes the water and helps the crust brown and blister). Boil 2-3 bagels at a time for 1 minute per side. Drain on a wire rack for 30 seconds.

Optional: brush the tops with an egg wash (1 egg beaten with 1 tablespoon water) for an extra-shiny crust, or sprinkle with seeds, salt, or everything bagel seasoning after draining.

Step 6: Bake (20-25 minutes)

Place the bagels on a parchment-lined sheet pan (or a baking stone). Bake 20-25 minutes, flipping once at the halfway point, until deep golden brown. The internal temperature should reach 200F.

Let cool on a wire rack for at least 15 minutes before cutting. Bagels continue cooking as they cool.

What Toppings Work Best on Bagels?

Classic New York bagels use simple, bold toppings. Brush with egg wash first, then dip in your topping of choice before baking:

• Plain: just egg wash, nothing else. Lets the bagel flavor shine.
• Sesame: white or black sesame seeds, pressed firmly.
• Poppy seed: classic for lemon-bagel pairings.
• Everything bagel: mix of sesame, poppy, dried garlic, dried onion, flaky salt.
• Cinnamon raisin: press in 1 cup raisins after boiling, dust with cinnamon sugar before baking.
• Salt and pepper: coarse salt and cracked black pepper.
• Asiago cheese: grated asiago pressed on before baking.

Why Do My Bagels Deflate or Lose Their Shine?

Bagels deflate when boiled

Cause: under-proofed or too soft when going into the water.

Fix: make sure the cold proof is at least 12 hours. The bagels should feel firm and cold when you take them out. If they are very soft, give them another hour in the fridge.

Bagels are too dense or gummy

Cause: too much flour, or not enough fermentation.

Fix: measure flour by weight. Use exactly 500g for this recipe. Make sure the bulk ferment is long enough: 50% rise is the minimum. The cold proof also continues fermentation, so 12-16 hours is essential.

Bagels have no shine

Cause: skipped egg wash, or boiled in plain water.

Fix: always use baking soda or malt in the boiling water (alkaline water is what gives the signature shine). For extra gloss, brush with egg wash before adding toppings.

Bagels are too thick (no hole)

Cause: shaped the hole too small, or it closed up during proofing.

Fix: stretch the hole to at least 1.5 inches when shaping. During the cold proof, check the bagels: if the hole has shrunk significantly, stretch it again before boiling.

Are Sourdough Bagels Worth Making at Home?

Sourdough bagels look intimidating but are surprisingly forgiving. The high-protein dough and cold proof make the shaping easy, the boil gives the classic chew, and the bake is fast. The result is a bagel that beats anything you can buy, with deeper flavor and better digestibility.
