There’s something magical about the moment when a warm bagel emerges from boiling water, its surface glossy and perfectly set, ready to be toasted to golden perfection. Sourdough discard bagels solve one of home fermentation’s best-kept problems: what to do with all that starter you need to discard to keep your culture healthy.
This recipe transforms that discarded starter into chewy, tangy bagels with a flavor profile that bakery versions simply can’t match. You get restaurant-quality texture and depth without requiring advanced shaping skills or commercial equipment.
The result is a bagel that’s crispy on the outside, wonderfully chewy inside, and packed with that subtle sourdough tang that makes every bite taste like it came from a professional kitchen. Best of all, you’re using ingredients you already have on hand.

My Experience Making This Recipe
I first made these bagels on a lazy Saturday morning when my sourdough starter was overflowing. I’d been tossing out discard for weeks and decided there had to be a better way than composting perfectly good starter.
The first batch taught me that patience with the final rise makes all the difference. I pulled them out of the fridge after just 4 hours and ended up with dense, gummy bagels that barely held their shape.
By the third batch, I’d learned to let them proof overnight, and the transformation was remarkable. They puffed up in the boiling water, turned golden brown, and had that perfect chew that made me feel like I’d unlocked something special in my kitchen.

Ingredients for Sourdough Discard Bagels
- Active sourdough discard: 150 grams (about 3/4 cup)
- Bread flour: 350 grams (about 2 3/4 cups)
- Water: 180 milliliters (about 3/4 cup), divided
- Sea salt: 6 grams (about 1 teaspoon)
- Honey: 10 grams (about 2 teaspoons)
- Baking soda: 15 grams (about 1 tablespoon) for boiling water
- Toppings (optional): sesame seeds, everything bagel seasoning, poppy seeds, coarse salt
Ingredient Notes and Substitutions
- Sourdough discard: This is the part of your starter you remove before feeding, providing the tangy flavor and leavening power that makes these bagels special. You can substitute with 150 grams of active starter at peak rise if you don’t have discard available, though the flavor will be slightly less developed.
- Bread flour: High protein content creates the chewy, elastic crumb that defines a proper bagel. All-purpose flour works but produces slightly softer bagels with less chew.
- Water: Cold water slows fermentation and improves dough structure, which is why it’s used here rather than warm water. Room temperature water is acceptable if your kitchen is cool, but boiling water will kill the yeast and ruin the batch.
- Honey: This feeds the yeast and helps develop crust color during boiling and baking. Malt powder adds extra bagel flavor if you can find it, using the same weight as honey.
- Baking soda: Raising the pH of boiling water creates the signature bagel exterior and helps develop color quickly. Table salt can be used in equal amounts if baking soda is unavailable.
How to Make Sourdough Discard Bagels
Step 1: Mix the Dough
Combine your sourdough discard, bread flour, 160 milliliters of cold water, and honey in a large mixing bowl. Mix by hand until a rough, shaggy dough forms with no dry flour visible, about 2 minutes of stirring.
This initial mixing hydrates the flour and begins gluten development, which is essential for bagel chewiness. Don’t worry if the dough looks rough at this stage; it will become smooth with time and kneading.
Step 2: Autolyse Rest
Cover your bowl with plastic wrap and let the dough rest at room temperature for 30 minutes. This autolyse period allows the flour to fully absorb water and relaxes the gluten, making the next kneading stage easier and more effective.
You’ll notice the dough becomes smoother and slightly more elastic just from sitting, even without any hands-on work. This is the gluten resting and reorganizing itself naturally.
Step 3: Knead and Add Salt
After the 30-minute rest, add your sea salt and the remaining 20 milliliters of water to the dough. Knead in a stand mixer on medium speed with a dough hook for 8 to 10 minutes, or by hand for 12 to 15 minutes, until the dough becomes smooth, elastic, and slightly tacky but not sticky.
Salt strengthens gluten and controls fermentation speed, so adding it after the autolyse prevents it from over-tightening the dough initially. You’ll feel the dough transform from rough and sticky to smooth and cohesive as you knead, a satisfying sign that everything is working.
Step 4: First Bulk Fermentation
Transfer your kneaded dough to a lightly oiled bowl, cover it with plastic wrap, and let it sit at room temperature for 3 to 4 hours. The dough should increase in volume by about 50 percent and feel puffy and airy when gently poked.
Room temperature fermentation develops flavor and structure gradually, creating better texture than warm fermentation would. If your kitchen is very warm (above 75 degrees Fahrenheit), reduce the fermentation time to 2.5 to 3 hours to prevent over-proofing.
Step 5: Divide and Pre-Shape
Gently turn the bulk-fermented dough out onto a lightly floured work surface and divide it into 8 equal pieces using a bench scraper or knife, aiming for about 110 grams each. Shape each piece into a loose round by gently tucking the edges underneath.
Dividing by weight ensures even-sized bagels that cook consistently and look professional. Pre-shaping creates surface tension that helps the bagels maintain their round shape during the next rest.
Step 6: Bench Rest
Let the shaped dough rounds rest on your work surface under a towel or plastic wrap for 15 to 20 minutes. This brief rest allows gluten to relax, making the final shaping much easier and more forgiving.
If you skip this rest, the dough will resist stretching and may spring back to a smaller size. The brief pause makes a significant difference in how easily the next step proceeds.
Step 7: Final Shaping into Bagels
Take one pre-shaped round and poke your thumb through the center to create a hole, then gently stretch the dough into a ring with a 2 to 3 inch hole in the middle. The ring should feel substantial and hold its shape without tearing.
Creating the hole by hand rather than with a bagel pan gives you more control over the thickness and ensures even cooking. The hole prevents a doughy, undercooked center that can happen if the bagel is shaped too thick.
Step 8: Cold Retard Overnight
Place your shaped bagels on parchment paper, cover them loosely with plastic wrap, and refrigerate them for 8 to 16 hours. The cold temperature slows fermentation dramatically while allowing complex flavors to develop.
This long cold fermentation is what transforms these from good bagels to exceptional ones with deep sourdough flavor. The cold also makes the dough firm enough to handle boiling without losing its shape or puffing up before cooking.
Step 9: Boil the Bagels
Fill a large pot with 2 to 3 liters of water and bring it to a boil, then add 15 grams of baking soda. Gently place each bagel into the boiling water and let it boil for 90 seconds per side, about 3 minutes total, using a slotted spoon to flip them halfway through.
The baking soda bath is what creates the chewy exterior, dark color, and that subtle pretzel-like flavor. Don’t skip this step or try to bake them directly; unboiled bagels will bake up more like bread rolls than true bagels.
Step 10: Add Toppings and Bake
Remove each bagel from the boiling water with a slotted spoon, place it on a parchment-lined baking sheet, and immediately add your chosen toppings while the surface is still wet and sticky. Bake in a preheated 450 degree Fahrenheit oven for 20 to 25 minutes, until the bagels are deep golden brown and sound hollow when tapped on the bottom.
Applying toppings immediately after boiling ensures they stick properly to the damp surface. The high oven temperature creates a crackling crust while keeping the inside chewy and underdone, the hallmark of a proper bagel.
Pro Tip: Don’t rush the overnight cold fermentation; those extra hours transform the flavor and make boiling much easier. Bagels that haven’t had proper time in the fridge will puff up too quickly in the boiling water and may develop a gummy interior.
Tips for the Best Sourdough Discard Bagels
- Use active, bubbly sourdough discard at peak rise for the best fermentation and flavor. If your discard is sluggish or not bubbly, your starter may need refreshment.
- Invest in a kitchen scale for this recipe; volume measurements can vary by 10 to 15 percent, which affects hydration and final texture significantly.
- Keep your boiling water at a rolling boil throughout the process; cooler water won’t create the proper exterior seal and color.
- Flip the bagels exactly halfway through the 3-minute boil to ensure even cooking on both sides and symmetrical development of the exterior.
- Don’t crowd the boiling pot; cook no more than 3 to 4 bagels at once to maintain water temperature and prevent bagels from sticking together.
- Cool baked bagels on a wire rack for at least 20 minutes before slicing; the crumb continues to set during this time, and cutting too early creates a dense, gummy slice.
Common Mistakes to Avoid
- Skipping the long overnight cold fermentation in favor of a shorter room-temperature rise produces bagels with flat, under-developed flavor and a texture more like bread rolls than true bagels.
- Using warm water instead of cold water accelerates fermentation too much, leading to over-proofing and bagels that collapse or develop large holes when boiled.
- Neglecting to boil the bagels at all and trying to bake them directly results in dense, cakey crumb with a soft crust that lacks the characteristic bagel chew.
- Boiling for too long or at too low a temperature creates a thick, doughy layer rather than a chewy, structured exterior, making the bagel feel heavy and bland.
- Cutting bagels while still warm causes the crumb to tear and compress, resulting in uneven slices and wasted bagels; patience during cooling prevents this frustration.
Serving Suggestions
Serve these bagels fresh and warm, sliced in half and toasted until the interior is steaming and the exterior is crispy. They pair beautifully with classic toppings and work equally well for breakfast, lunch, or even casual dinner snacks.
- Cream cheese, smoked salmon, and thin slices of red onion for an elegant morning meal
- Butter and jam for a simple, comforting breakfast that lets the bagel flavor shine
- Avocado, lemon juice, sea salt, and cracked black pepper for a modern, healthy option
- Peanut butter and honey for a satisfying snack that feels indulgent but requires minimal prep
- Egg, cheese, and bacon for a substantial breakfast sandwich that fills you up for hours
Variations to Try
- Everything Bagels: Mix sesame seeds, poppy seeds, dried garlic, dried onion, and sea salt into a single topping blend and coat wet bagels generously before baking for a savory, complex flavor profile that pairs wonderfully with cream cheese.
- Cinnamon Raisin Bagels: Add 80 grams of raisins and 5 grams of ground cinnamon to the dough during mixing, then bake without any topping to showcase the sweet spice and chewy raisins throughout.
- Whole Wheat Sourdough Bagels: Replace 50 grams of bread flour with whole wheat flour for a nuttier flavor and denser crumb; whole wheat absorbs more water, so reduce the water by 20 milliliters to maintain proper dough consistency.
- Herb and Cheese Bagels: Mix 100 grams of grated sharp cheddar cheese, 10 grams of dried herbs like rosemary and thyme, and 5 grams of cracked black pepper into the dough during the final mixing stage for a savory bagel that works perfectly with egg sandwiches.
- Asiago and Peppercorn Bagels: Top boiled bagels generously with grated Asiago cheese and cracked black pepper just before baking; the cheese melts into the bagel exterior and creates a crispy, savory crust with subtle heat.
Dietary Adaptations
- Gluten-Free: Substitute King Arthur’s Gluten-Free Bread Flour at a 1:1 ratio by weight, though the dough will be slightly stickier and the texture slightly less chewy; add an extra 10 milliliters of water to compensate for gluten-free flour’s higher absorption rate.
- Dairy-Free: This recipe contains no dairy, so it is naturally dairy-free; simply ensure your sourdough starter was created and maintained with non-dairy ingredients if that is your requirement.
- Vegan: This recipe is already vegan; honey can be replaced with agave syrup or maple syrup in equal amounts if you prefer a fully plant-based approach.
- Lower-Carb/Keto: Substitute 50 percent of the bread flour with almond flour and add 5 grams of xanthan gum to maintain structure; expect a slightly denser crumb and nuttier flavor, and reduce the water to 140 milliliters to account for almond flour’s lower absorption.
Storage and Reheating
Refrigerator
Store cooled bagels in an airtight container or zipper-top bag in the refrigerator for up to 5 days. The cool temperature preserves texture better than leaving them on the counter, where they will dry out and harden.
- Slice bagels before storing if you prefer to toast them directly from the fridge
- Wrap individual bagels in parchment before bagging to prevent them from sticking together
Freezer
Wrap each cooled bagel individually in parchment paper, then place them in a freezer-safe zipper-top bag with as much air removed as possible, and freeze for up to 3 months. Proper wrapping prevents freezer burn and maintains the bagel’s chewy texture.
- Label the bag with the date to track freshness
- You do not need to thaw bagels before toasting; toasting them directly from frozen actually produces excellent results
Reheating
Toasting is the best method for reheating; split the bagel and toast the cut sides in a toaster or toaster oven until the interior is warm and the exterior is crispy, about 2 to 3 minutes. This restores the chewy texture and prevents the bagel from becoming dense or rubbery.
- Microwaving softens the bagel permanently and is not recommended
- A brief oven warming at 350 degrees Fahrenheit for 8 to 10 minutes also works well if you prefer whole bagels or are warming multiple bagels at once

Frequently Asked Questions
Can I use fresh sourdough starter instead of discard?
Yes, you can use 150 grams of active starter at peak rise, though the flavor will be slightly less tangy and developed. If you do this, reduce the overall hydration slightly by using only 170 milliliters of water instead of 180 milliliters, as fresh starter contains more moisture than discard.
What if my sourdough starter is not bubbly or active?
Your starter needs to be fed and left at room temperature for 4 to 8 hours until it doubles in size and shows plenty of bubbles on the surface before using it in this recipe. If your starter is sluggish, feed it once a day for 2 to 3 days to build up activity and strength.
Can I skip the overnight refrigeration and make these bagels the same day?
You can, but the results will be noticeably less flavorful and the bagels may not hold their shape as well during boiling. The minimum cold fermentation for decent results is 4 to 6 hours, though overnight truly makes the best bagels.
Why do my bagels develop a gummy center even after baking?
This usually happens when the bagel hole is too small, trapping moisture in the center and preventing it from cooking through. Make sure your hole is at least 2 to 3 inches in diameter, and avoid using a particularly thick shaping that would create extra density in the middle.
Can I double this recipe to make 16 bagels?
Yes, simply double all the ingredient amounts and follow the same timing; the bulk fermentation may take 4 to 5 hours instead of 3 to 4 hours because you’ll have more dough generating heat. The boiling process will take longer since you’ll need to work in smaller batches to avoid overcrowding the pot.
What’s the difference between these sourdough bagels and regular yeast bagels?
Sourdough bagels develop complex, tangy flavor during the long fermentation and contain beneficial bacteria and wild yeast that aid digestion. They also typically stay fresher longer and have a more interesting crumb structure than straight dough fermented with commercial yeast alone.
Final Thoughts
Making bagels at home transforms the way you think about breakfast and gives you a direct connection to your sourdough starter that goes beyond bread baking. You’re not just using discard; you’re creating something bakery-quality that your family and friends will remember.
The first time you pull a batch of golden, chewy bagels from your oven, warm enough to smell their rich sourdough aroma, you’ll understand why this recipe is worth the patience and planning it requires. Give these bagels a try, and I bet you’ll find yourself making them regularly.
