Why Is My Sourdough Crust Too Hard?

The short answer

A sourdough crust can become too hard when too much moisture is lost during baking or storage.

Common causes include:

baking too long
baking uncovered for too long
storing the loaf incorrectly
your preferred crust style being different from traditional sourdough

A crisp crust is normal, but it should still be enjoyable to eat.

Why does sourdough have a crust?

During baking, the outside of the dough dries out and browns through a process called the Maillard reaction.

This creates:

colour
flavour
aroma
texture

A good sourdough crust has character—but it shouldn't feel like you're fighting your bread.

Common reasons your crust is too hard

1. It baked too long

A longer bake creates a thicker, darker crust.

If your loaf is becoming difficult to cut or chew, try:

reducing the uncovered baking time
checking your oven temperature
removing the loaf once it reaches your preferred colour

Remember, every oven behaves differently.

2. Too much time uncovered

The uncovered stage is where your crust develops.

This is important for colour and texture, but too long can dry the crust out.

If you prefer a softer crust, experiment with shortening this stage.

3. Your loaf cooled uncovered

A freshly baked loaf continues releasing moisture as it cools.

Leaving it uncovered for a long time can create a thicker, firmer crust.

Once cooled, storing it correctly helps maintain a better texture.

4. Storage affects crust

How you store your bread changes the crust.

For a crispier crust:

store loosely wrapped

For a softer crust:

use a bread bag or container

There is no right or wrong answer—it depends on what you enjoy.

5. The crust is naturally different from supermarket bread

Many people are used to soft packaged bread.

Sourdough is different.

Because it is usually made with simple ingredients and without softening agents, the crust naturally has more texture.

This is part of what makes it special.

How can I get a softer sourdough crust?

Try:

✓ reducing the uncovered baking time
✓ storing your cooled loaf in a bread bag
✓ allowing the loaf to cool fully before storing
✓ adjusting your bake based on your preferred texture
✓ add a splash of olive oil to your mix

A softer crust doesn't mean you failed.

It means you know what your family enjoys.

Can I soften a hard crust after baking?

Yes.

Some options:

store the loaf in a bread bag once cooled
lightly warm slices before eating
use it for toast or sandwiches

Sourdough has many lives—even when the crust isn't exactly what you wanted.

Nikki's note

When I first started making sourdough, I thought a super thick, crunchy crust meant I had done it right.

But then I realised something important:

The "perfect" loaf is the one people can eat without breaking a tooth (haha).

For my family, that means a loaf with beautiful flavour and a crust that's enjoyable
