We know every sourdough baker has been there — excitedly yanking their loaf from the oven only to find that the bottom is completely burnt and bitter.
It gets frustrating, particularly when you just put in countless hours babying the dough to perfection.
But don’t worry—this article will guide you through how to fix and prevent burnt bottom sourdough, saving your future bakes.
We’ll cover the common culprits behind this issue, practical tips to achieve an even bake, and some tools of the trade that will elevate your sourdough game.
By the end, you’ll feel confident in baking loaves with perfectly golden crusts and no charred surprises.
Burnt Bottom Sourdough Fixes That Work
A scorched loaf isn’t just an unfortunate fluke—it’s often the result of a few small, correctable mistakes.
Understanding why this happens is the first step to solving it.
Here’s what could be going wrong:
Baking at Too High a Temperature
Sourdough bread requires high heat for that coveted crust and rise, but sometimes the temperature is just too high.
When your oven or baking surface gets overly hot, it transfers too much direct heat to the bottom of your loaf, leaving it burned while the rest of the bread bakes unevenly.
Positioning the Loaf Too Close to the Heat Source

If you bake on the bottom rack or directly on a baking stone without a buffer, the proximity to the heat can scorch your bread.
Ovens often distribute heat unevenly, with the bottom being significantly hotter than the top.
Using an Improper Baking Surface
Baking directly on a metal tray or thin pan can intensify the problem, as these materials conduct heat more aggressively.
A poorly insulated baking surface doesn’t allow for even heat distribution, leaving the bottom of your loaf vulnerable to burning.
Skipping Parchment Paper or a Buffer Layer
You will need to create a barrier between your dough and the heat source and this is where parchment paper or a thin layer of flour can come in handy.
The crust ultimately gets charred when it meets the endless roof of brick dust since there’s no insulation to save its gentle bottom.

Now that you know the causes, here’s how to stop it from happening:
Lower the Oven Temperature
Instead of starting at a blazing 500°F, consider reducing your oven to 450°F after the first 20 minutes of baking.
This gives your loaf a head start with a good rise while avoiding excess heat exposure later.
Elevate Your Loaf
Place your sourdough higher in the oven, away from the direct heat.
If you’re using a Dutch oven, consider placing it on a rack closer to the middle rather than the bottom.
Invest in a Baking Stone or Steel
These tools help distribute heat evenly across the surface, reducing the risk of burning.
Preheat the stone thoroughly before baking for the best results.
Add an Insulation Layer

Line with parchment paper, double layer of foil or semolina on the baking surface.
Though minor, these adjustments can act as buffers for heat and will save your already fragile bottom crust from scorching.
Rotate the Loaf Midway
Halfway through baking, rotate your loaf to ensure it cooks evenly on all sides.
This prevents one area from getting too much direct heat for too long.
What to Do If Your Loaf’s Bottom Is Already Burnt
Don’t toss that loaf just yet!
If the bottom of your sourdough has already burned, you can salvage it:
- Scrape Off the Burnt Section: Use a serrated knife or grater to gently remove the blackened layer.
- Slice Strategically: Cut the loaf horizontally and use the unburnt top for sandwiches or toast.
- Repurpose the Bread: Croutons, bread pudding, or breadcrumbs hide the burnt flavors and make good use of your loaf.
Why Does My Oven Burn the Bottom of My Bread?
An oven that consistently burns bread might have uneven heat distribution or temperature calibration issues.
To fix this:
- Test Your Oven’s Temperature: Use an oven thermometer to check if the temperature matches the setting. Adjust as needed.
- Create an Even Baking Environment: Add a baking stone to help regulate the oven’s internal temperature.
- Use Convection Settings Carefully: If your oven has a convection option, reduce the temperature by 25°F to account for the fan-driven heat circulation.
Additional FAQs:
- Can I bake sourdough without parchment paper?
Yes, but use an alternative like a silicone baking mat, semolina, or a layer of flour to prevent sticking and burning.
- Does a Dutch oven help with burnt bottoms?
Yes, especially if paired with parchment paper or a trivet to elevate the loaf slightly.
- How do I know my oven is preheated evenly?
Allow at least 30 minutes for full preheating and use an oven thermometer to check different zones.
How to Get That Perfect Sourdough Crust Without Burnt Bottoms
by Miserable_Guava6587
Achieving a sourdough loaf with a crisp crust and evenly baked interior takes a little finesse but is absolutely doable.
Focus on these essentials:
Steam During the First Bake Phase
Steam helps create that signature sourdough crust while preventing the loaf from drying out too quickly.
Use a tray of water in the oven or bake in a covered Dutch oven for the best results.
Monitor the Bake Time Closely
Set timers for each phase of baking—initial high heat and then reduced temperature—to prevent overbaking.
Experiment With Recipes
Some doughs are more prone to burning due to sugar content in the recipe. Adjust your formula if needed for a better balance.
Additional FAQs:
- Can burnt bottoms ruin the flavor of sourdough?
Yes, but only the outer crust is affected. Removing the burnt part often reveals a delicious loaf beneath. - How can I avoid sticking and burning in one step?
Use a floured banneton for proofing and parchment paper during baking for an easy release and barrier. - What’s the best tool for slicing burnt sourdough?
A serrated knife works best to cut through tough or burnt crusts without crumbling the loaf.
With a few thoughtful adjustments and some patience, burnt bottom sourdough can become a thing of the past.
Armed with these tips, you’ll master sourdough baking and enjoy loaves that are beautifully golden from top to bottom.
