Recipe Instructions for Sourdough Discard Bagels

Follow these step-by-step instructions to create perfectly chewy, golden sourdough discard bagels. Each step includes estimated times, helpful tips, and clear guidance to ensure success.

Step 1: Preparing the Dough (10 minutes + 1-hour rest)

  1. Combine the sourdough discard, warm water, and sugar in a large mixing bowl. Stir until the sugar is dissolved.
  2. Add the flour, salt, and instant yeast. Mix until a rough dough forms.
  3. Manually knead the dough on a lightly floured surface for approximately 8–10 minutes, taking care to achieve a smooth and elastic texture. For a quicker option, use a stand mixer equipped with a dough hook, which can accomplish the same result in 5–7 minutes.
  4. Place the dough in a greased bowl, Cover with a damp towel and let rise for an hour or until doubled.

Tip: If the dough is excessively sticky, incorporate one tablespoon of flour at a time until the desired consistency is achieved.

Step 2: Shaping the Bagels (15 minutes)

  1. Punch down the dough and split it into 8 even pieces.
  2. Take each piece of dough and roll it into a smooth, round ball. Using your thumb, gently press through the centre of the ball to create a hole, forming the classic bagel shape.
  3. Gently stretch the hole until it’s about 1–2 inches wide. Repeat for all pieces.

Tip: Make the holes slightly larger than you think; they’ll shrink during boiling and baking.

Step 3: Fermenting the Dough (30 minutes or overnight)

  1. Let the shaped bagels rest for 30 minutes at room temperature for quick fermentation.
  2. Put the bagels on a baking sheet once they’re shaped, cover, and refrigerate overnight for deeper flavour.
  3. Tip: Overnight fermentation enhances the tangy flavor from the sourdough discard.

Step 4: Boiling and Baking the Bagels (10 minutes boiling + 20–25 minutes baking)

  1. Preheat to 425°F (220°C) and line a baking sheet with parchment.
  2. Bring a large pot of water to a boil and carefully incorporate the baking soda.

Tip: Baking soda gives bagels their signature chewy crust and golden colour.

3. Boil each bagel for 1 minute per side, remove with a slotted spoon and place on the prepared baking sheet.

4. Immediately sprinkle toppings on the wet bagels.

5. Bake for 20–25 minutes, or until golden brown.

Tips for Perfect Sourdough Discard Bagels

Mastering sourdough discard bagels takes practice, but these tips will help you achieve bakery-quality results every time.

Key Tips for Success

  • Use high-gluten flour: Choose bread flour, or enhance the texture of all-purpose flour by incorporating vital wheat gluten for a chewier result.
  • Weigh your ingredients: A kitchen scale ensures precision, especially for flour and sourdough discard.
  • Boil for the right time: Boil bagels for 1–2 minutes per side. A longer boil creates a thicker, chewier crust, while a shorter boil results in a softer bagel.
  • Shape with care: Make the bagel holes slightly larger than you think; they’ll shrink during boiling and baking.
  • Top immediately after boiling: Sprinkle toppings while the bagels are wet to ensure they stick.

Common Mistakes to Avoid

  • Avoid overproofing: Overproofed dough can deflate during boiling, leading to flat bagels.
  • Please don’t skip the boil: Skipping this step results in bagels that lack their signature chewiness and glossy crust.
  • Watch your oven temperature: An oven that’s too hot or cold can lead to uneven baking. Use an oven thermometer for accuracy.
  • Don’t over-flour the dough: Incorporating excessive flour can result in a dry, challenging-to-handle dough.

Pro Tips for Customization

  • Experiment with fermentation: Refrigerate the shaped bagels overnight for a deeper sourdough flavour.
  • Get creative with toppings: Mix and match seeds, herbs, or spices for unique flavour combinations.
  • Try mix-ins: Add raisins, cinnamon, cheese, or jalapeños to the dough for a creative twist.

By adhering to these guidelines and steering clear of common errors, you can bake the perfect batch of sourdough discard bagels every time!

Variations and Creative Ideas for Sourdough Discard Bagels

Bagels are incredibly versatile, and you can easily customize them to suit your tastes. Here are some sweet and savoury variations to inspire your next batch of sourdough discard bagels.

Sweet Variations

  1. Cinnamon Raisin: Incorporate 1 teaspoon of ground cinnamon and ½ cup of raisins to the dough for a warm, spiced flavour.
  2. Chocolate Chip: Mix in ½ cup of chocolate chips for a sweet treat perfect for breakfast or dessert.
  3. Honey Almond: Brush the bagels with honey before baking and sprinkle with sliced almonds for a nutty, caramelized finish.

Savory Variations

  1. Garlic Herb: Add 1 teaspoon of garlic powder and dried herbs (like rosemary or thyme) to the dough, and sprinkle minced garlic.
  2. Jalapeño Cheddar: Fold in diced jalapeños and shredded cheddar cheese for a spicy, cheesy kick.
  3. Sesame Onion: Mix in diced onions and top with sesame seeds for a classic deli-style flavour.

FAQ About Sourdough Discard Bagels

Are sourdough bagels healthier than regular bagels?

Sourdough bagels can be healthier than regular bagels because the fermentation process breaks down phytic acid, making nutrients in the flour more bioavailable. Additionally, sourdough may have a lower glycemic index and be easier to digest due to the natural probiotics and longer fermentation.
A scientific study by the National Center for Biotechnology Information (NCBI) highlights how sourdough fermentation improves nutrient availability, enhances digestion, and reduces the glycemic response to baked goods. Read the full article here.
However, the health benefits of sourdough bagels still depend on the specific ingredients used and portion size. Moderation and balanced nutrition remain key!

Is eating sourdough discard healthy?

Eating sourdough discard is healthy if it is unfed and adequately stored. It contains beneficial bacteria from the fermentation process and retains the flour’s nutrients. When baked into recipes like bagels, pancakes, or crackers, it’s a great way to enjoy its flavour and nutritional benefits.

Why are my sourdough bagels so chewy?

The chewiness of sourdough bagels is due to the high-gluten flour and the boiling step before baking. Boiling the bagels gelatinizes the starches on the surface, locking in moisture and creating a dense, chewy texture. If your bagels are too chewy, consider cooking them for less time or using all-purpose flour instead of bread flour.

Why can’t you use sourdough discard for bread?

Sourdough discard is less active than an active sourdough starter, meaning it lacks the leavening power to properly rise a loaf of bread. However, it’s perfect for recipes like bagels, pancakes, and crackers, where additional yeast or leavening agents can be added for the desired texture.

Why did my sourdough bagels come out dense?

Dense sourdough bagels often result from:
Underproofing: The dough didn’t rise enough before boiling.
Overproofing: The dough rose too much and collapsed.
Improper boiling: Boiling for too long can make the bagels dense.
To fix this, Carefully track your proofing time to avoid over- or under-proofing, and ensure your yeast is fresh and active to guarantee the best rise and flavor.

Can I freeze sourdough discard bagels?

Absolutely! Sourdough discard bagels freeze well for up to 3 months. Let them cool completely, wrap each one tightly, and store in a freezer-safe bag. Thaw at room temperature or reheat in an oven or toaster for a fresh, warm texture.

How do you fix chewy sourdough discard bagels?

If your sourdough discard bagels are too chewy, try shortening the boiling time or using lower-gluten flour. For tough bagels, ensure your dough isn’t over-kneaded or over-proofed.

How do you fix chewy sourdough bread?

If your sourdough bread is too chewy, try these solutions:
Shorten kneading time: Over-kneading can develop too much gluten, leading to excessive chewiness.
Use a mix of flours: Replace some bread flour with all-purpose flour for a softer texture.
Adjust hydration: A higher water content can create a lighter crumb.
Monitor fermentation: Ensure proper proofing times to prevent overly dense or gummy textures.
Their chewiness is a desired trait for bagels, but for bread, balancing gluten development and hydration is key.
