Making sourdough bagels can be a rewarding experience, but when they turn out flat, it can be frustrating. If you’ve ever wondered, “Why did my sourdough bagels turn out flat?”, you’re not alone. Many home bakers face this issue, and the good news is that it’s often preventable with a bit of knowledge and the right techniques. In this comprehensive guide, we will dive into the most common reasons for flat sourdough bagels and offer detailed solutions to help you get the perfect rise. Let’s break it down so you can troubleshoot, fix, and avoid flat bagels in the future.
Understanding the Basics: Why Sourdough Bagels Might Flatten
Sourdough bagels are not your ordinary bread. The process of making them involves a delicate balance between yeast activity, gluten development, and hydration. For more details on why your sourdough bagels might be chewy instead of flat, check out Why Are My Sourdough Bagels So Chewy?. Bagels should be chewy and thick, with a shiny, well-baked crust. But when the dough flattens, this structure is compromised. To clarify, the reason for flat sourdough bagels usually comes down to a combination of factors that influence dough structure and how the bagels react to boiling and baking.
Above all, it’s essential to understand how fermentation, gluten development, and dough hydration all play crucial roles in the final shape of your bagels. Without the proper handling of these factors, even the best recipes will fall flat. This guide will help you identify what might be going wrong and how to correct these issues.
The Role of Gluten Development in Sourdough Bagels
Firstly, gluten development is vital when making any bread, but for sourdough bagels, it is even more critical. Gluten forms a network that traps gas bubbles produced by yeast during fermentation. Without a strong gluten network, your bagels will lack the structure necessary to rise properly.
The kneading process is essential to this, and kneading until the dough passes the windowpane test is a good indication that you’ve developed enough gluten. The windowpane test involves stretching a small piece of dough between your fingers until it forms a thin membrane. If the dough stretches without tearing, it means enough gluten has developed.
However, underkneading can result in weak gluten, causing your bagels to flatten when boiled or baked. On the other hand, overkneading can break down gluten, leading to tough dough that doesn’t rise well. Striking the right balance is crucial for successful sourdough bagels.

How to Develop Gluten Properly
- Start with the right flour: High-protein flour (such as bread flour) helps develop more gluten.
- Knead until smooth: Knead the dough for 10–15 minutes or until smooth and elastic. If it feels too sticky, add small amounts of flour.
- Perform the windowpane test: Test a small piece of dough by stretching it to see if it forms a thin layer without tearing.
When you follow these steps, you’ll create the strong gluten network necessary to hold gases and create the desired bagel shape. For more tips on maintaining texture, check out When to Add Toppings to Sourdough Bagels.
The Importance of Fermentation in Bagels
Fermentation is a process where yeast and bacteria break down sugars in the dough, releasing carbon dioxide. This creates the air pockets that allow bread, including sourdough bagels, to rise. However, fermentation timing is critical. If the dough is allowed to ferment for too long, the gluten structure can weaken, and the dough will collapse.
In other words, overproofing is one of the most common reasons for flat sourdough bagels. Overproofing occurs when the dough ferments beyond the point of optimal gas retention. As a result, the dough expands too much and then deflates during boiling or baking. In contrast, underproofing can also result in flat bagels, as the dough hasn’t developed enough gas to rise properly.
Monitoring the fermentation process closely will help ensure that your bagels rise just right. One way to test if your bagels are ready for boiling is by performing the float test, which involves placing a shaped bagel in water. If it floats, it’s ready to boil. If it sinks, the dough needs more time to proof.
Preventing Flat Sourdough Bagels: Troubleshooting the Process
While there are several reasons your sourdough bagels may turn out flat, you can troubleshoot and fix each issue. Let’s explore each potential problem and how to solve it.
1. Overproofing Your Dough
When the dough ferments for too long, it becomes overproofed. Overproofed dough will deflate easily after boiling or when it enters the oven. To avoid this, it’s essential to monitor the proofing time carefully. A good indicator of whether your bagels are ready to bake is the float test.
Solution:
- Use the float test before boiling your bagels to determine if they are proofed enough.
- Keep an eye on fermentation times. If you notice the dough expanding too quickly, it’s time to slow down the process by refrigerating it.
2. Underdeveloped Gluten
As mentioned earlier, underdeveloped gluten leads to flat bagels. Without a strong gluten network, the dough cannot trap enough gas to maintain its shape during boiling and baking. This causes the bagels to collapse.
Solution:
- Knead the dough sufficiently to develop gluten.
- Use the windowpane test to check the dough’s elasticity.
- Make sure you’re using high-protein flour, which helps build gluten strength.
3. Excess Dough Moisture
Hydration levels play a key role in the success of sourdough bagels. If the dough is too moist, it can’t hold its shape well. Bagel dough needs to be firm and slightly stiff to maintain its shape during boiling. Find out more about bagel hydration levels in Why Did My Sourdough Bagels Turn Out Flat?.
Solution:
- Adjust the dough hydration by adding more flour if needed.
- Use a low-hydration dough (around 55–60% hydration) to get the right stiffness for shaping.
4. Improper Boiling Time
Bagels are boiled before baking to create a shiny crust and chewy interior. Learn more about the perfect texture by visiting Sourdough Bagel Recipe: The Ultimate Guide. However, if you boil the bagels for too long, they may deflate. The boiling process should be short—usually 30–60 seconds on each side—to prevent the dough from becoming waterlogged.
Solution:
- Boil bagels for 30–60 seconds on each side.
- Make sure your water is at a rolling boil before adding the bagels.
5. Low Oven Temperature
If your oven isn’t hot enough, your bagels won’t rise properly. Bagels need to bake at a high temperature (typically 425–450°F) to get the best rise. A hot oven ensures that the bagels set quickly, trapping the gases inside the dough.
Solution:
- Preheat your oven to at least 425°F.
- Use a baking stone to ensure even heat distribution.

Understanding Dough Hydration and Its Impact on Bagels
Hydration refers to the amount of water in relation to flour in the dough. In sourdough bagels, hydration is particularly important because a lower hydration level creates a firmer dough, essential for shaping and maintaining structure.
Too much water in the dough will result in bagels that are too soft and prone to flattening. In contrast, a properly hydrated dough will be easier to handle and will hold its shape during both boiling and baking.
How to Adjust Dough Hydration:
- Aim for a dough hydration level between 55–60%. This keeps the dough firm and easier to shape.
- If your dough feels too sticky, add flour in small increments until it becomes manageable.
Hydration is a key factor, and you can learn more about how to manage dough hydration by exploring understanding dough hydration, which gives insights into why it matters in baking.
The Importance of the Float Test in Sourdough Bagel Making
One of the best ways to determine if your bagels are ready to be boiled is by using the float test. The float test involves gently placing a shaped bagel into a bowl of water to see if it will float. If the bagel floats, it’s a sign that the dough has proofed enough and is ready for the next step, which is boiling. If it sinks, it indicates that the dough needs more time to proof, as it hasn’t developed enough gas to lift itself.
Performing the float test helps prevent both underproofing and overproofing, which are common issues when making sourdough bagels. If the dough is underproofed, it won’t have trapped enough gas, resulting in a dense, flat bagel. If the dough is overproofed, it may be too weak, and after boiling, it could collapse, leading to deflation. The float test, therefore, serves as a reliable checkpoint in your baking process.
How to Perform the Float Test:
- Shape your bagels and let them rest for 10–15 minutes.
- Fill a bowl with room-temperature water.
- Place one bagel in the water. If it floats, it’s ready to boil.
Tips for Fixing Flat Sourdough Bagels During Baking
Even with the best preparation, flat bagels can still happen. However, there are ways to fix this during the baking process.
Flipping Bagels During Baking
If you notice your bagels flattening on one side, try flipping them halfway through the bake. Flipping the bagels helps distribute the heat evenly, ensuring that one side doesn’t collapse while the other side gets too much heat.
Adding Steam to the Oven
Bagels benefit from steam during the initial phase of baking. The steam helps the dough expand, creating a good rise and a shiny crust.
How to Add Steam:
- Place a tray of water in the oven while baking the bagels.
- Alternatively, you can mist the bagels with water before placing them in the oven.
FAQs: Why Did My Sourdough Bagels Turn Out Flat?
