If your sourdough bread is coming out with an overly crispy or hard bottom, there are several potential causes and fixes. Here’s a breakdown of the most common reasons and how to avoid them:

If your sourdough bread is coming out with an overly crispy or hard bottom, there are several potential causes and fixes. Here’s a breakdown of the most common reasons and how to avoid them:
🔥 1. Baking Surface Too Hot
If you’re baking directly on a preheated baking stone or steel, the intense heat can crisp the bottom too much.
Fixes:
-
Lower the oven rack slightly (middle or one level above bottom).
-
Place a baking sheet underneath the stone/steel during the last 15–20 minutes of baking to deflect some of the heat.
-
Try preheating your baking stone for less time, or not at all if using cast iron or a Dutch oven.
🍞 2. Too Long on the Bottom Heat Source
If your bread sits too long in contact with hot metal (like in a Dutch oven or cast iron combo cooker), the bottom gets overdone.
Fixes:
-
Remove the loaf from the Dutch oven partway through baking (e.g., after the first 25 minutes when you remove the lid) and finish it on a wire rack or baking sheet.
-
Invert the Dutch oven setup so the lid is on the bottom and the loaf bakes on the less-conductive top part.
🌡️ 3. Oven Temperature Too High
If the oven is too hot, especially on the bottom, that will crisp the base excessively.
Fixes:
-
Lower your oven temperature by 15–25°F (10–15°C) and increase the bake time slightly.
-
Use an oven thermometer to verify your actual oven temperature—it may run hotter than the setting.
🧱 4. Lack of Buffering Layer
Direct heat contact crisps up the base; having a barrier can help.
Fixes:
-
Use parchment paper between the dough and the baking surface.
-
Place the dough on a sheet of aluminum foil or use a double baking sheet trick (stack two baking sheets to reduce heat conduction).
💨 5. Poor Heat Distribution
Some ovens heat unevenly, causing hot spots.
Fix:
-
Consider using convection mode (if available) to improve airflow and distribute heat evenly.
Bonus: Humidity Matters
If your dough is very wet, it might steam itself from underneath early in the bake, but then crisp overly later on.
Fix:
-
Make sure the bottom of your dough is floured or lightly dusted before baking to prevent excessive moisture buildup underneath.
