Why Is My Sourdough Crust So Hard? (And How to Soften It)
On This Page
A crust that could double as a doorstop usually comes down to oven conditions, not your dough. The good news is this one’s an easy fix.
The Short Answer
An overly hard sourdough crust is usually caused by too much direct heat, baking too long, or not enough steam early in the bake. Add steam, check your bake time, and try wrapping cooled loaves in a towel or bag to soften the crust further.
What’s Going Wrong (and How to Fix It)
Problem #1
There wasn’t enough steam in the oven during the first part of the bake, often because the Dutch oven lid came off too early, which lets the crust set and harden before it should
The Fix
Bake covered in a Dutch oven for the first 30 minutes to trap steam, then uncover for the remainder to brown
Problem #2
The loaf was baked too long or at too high a temperature for your specific oven, and an oven running 15 to 25 degrees hotter than its dial suggests is more common than people think
The Fix
Check your oven’s actual temperature with an oven thermometer, and pull the loaf a few minutes earlier next time if the crust is consistently too thick or dark
Problem #3
The loaf was left uncovered too long during cooling in a very dry kitchen
The Fix
For a softer finished crust, wrap the fully cooled loaf in a clean kitchen towel or paper bag overnight
Desi’s Note
A hard crust isn’t wrong, some people love that shatter. But if it’s harder than you want, it’s almost always a steam issue, not a dough issue.
