👩‍🍳 How to Make Sourdough Discard Bagels

Step 1: Mix the Dough

Combine sourdough discard, water, and sweetener in a large bowl. Stir until mostly smooth. Add bread flour and mix until a rough dough forms. Cover and rest 30 minutes.

Step 2: Add Salt and Knead

Add salt and knead dough on a lightly floured surface for 6–8 minutes until smooth and elastic. Alternatively, use a stand mixer with a dough hook for 5 minutes.

Step 3: Bulk Fermentation

Place dough in a lightly oiled bowl. Cover and let rise at room temperature for 6–8 hours, or refrigerate overnight after 2–3 hours. The dough should feel soft, puffy, and stretchy.

Step 4: Shape the Bagels

Divide dough into 8 equal portions. Shape each into a ball. Poke your finger through the center and gently stretch into a bagel shape. Rest on a parchment-lined tray for 30–60 minutes, uncovered.

Step 5: Boil the Bagels

Bring water to a boil, then add baking soda. Boil each bagel for 30 seconds per side. Drain and place back on the tray. Add toppings immediately while still wet.

Step 6: Bake

Preheat oven to 425°F (218°C). Bake for 20–22 minutes or until bagels are golden brown with a firm, shiny crust. Let cool at least 15–20 minutes before slicing.

💭 Pro Tips for First-Time Bagel Makers

• Use bread flour for proper chew. All-purpose works, but won’t give the same texture.
• Boil, don’t skip it — this step is what makes a bagel a bagel.
• Don’t overproof the shaped dough. It should rise slightly but hold its shape.
• Toppings stick best right after boiling. Dab with water if needed before baking.
• Want a softer crust? Bake with a pan of steam or cover the first 10 minutes.

🧠 Add-On: How to Store & Freeze Sourdough Discard Bagels

These bagels stay fresh for 2 days at room temperature in an airtight container — but they freeze beautifully too. Here’s how to store them right:

To store at room temp:

Let bagels cool fully. Place in a sealed bag or container for up to 48 hours. Reheat in the toaster.

To freeze:

Slice bagels in half. Place parchment between slices and freeze in a zip-top bag. They’ll keep for 2 months.

To reheat:

Toast directly from frozen or microwave for 20 seconds, then toast for crisp edges.

This makes them perfect for weekly meal prep, quick school mornings, or emergency carb cravings.

❓ FAQs

Can I use all-purpose flour instead of bread flour?
Yes, but the bagels will be slightly softer and less chewy.

Do I have to boil the dough?
Yes! Boiling sets the crust and gives bagels their signature chew and shine.

Can I add mix-ins like cheese or herbs?
Absolutely. Fold shredded cheese, garlic powder, or onion flakes into the dough before shaping.

What if I don’t have a stand mixer?
No problem. This dough is easy to knead by hand and very forgiving.

Are these bagels sour?
Only slightly. Discard adds a gentle tang without overpowering the flavor.
