Can You Freeze Sourdough Bread? The Complete Guide

In this article, you will know the answer to the query “Can You Freeze Sourdough Bread? The Complete Guide“.

In the process of dough fermentation, sourdough bread is created.

In order to accomplish this, yeast and lactobacilli are used.

This sour taste is caused by lactobacilli releasing lactic acid, which also enhances its keeping power.

When bakers tried to replicate French bread recipes, they created Sourdough bread.

Creating this French bread was difficult because it always tasted sour.

It was the yeast that thrived under San Francisco’s climate that created the taste.

Their amazing signature food was invented as a result of that experience.

This bread is believed to be impossible to make elsewhere by many people.

A yeast named Lactobacillus Sanfranciscensis is inspired by the city itself.

Sourdough bread can be frozen? There is no doubt in my mind that you can.

The benefit of freezing this bread is that you can enjoy it later on.

Baking or buying large quantities of this bread will make storing it inside the freezer easier.

Does Freezing Affect Sourdough Bread?

The taste and quality of your sourdough bread won’t be affected by freezing.

The lactic acid or yeast in your sourdough bread does not seem to be killed by freezing temperatures.

It is common for bacteria and yeasts to form spores that are dormant and inactive during distress, making them incompatible with life whenever they are dried or frozen.

The spores are resistant to extreme physical conditions such as freezing and drying.

Once the conditions are correct, the spores begin to rehydrate and become active living organisms.

If you keep your sourdough bread outside, it will lose its freshness and taste.

As a result of being exposed to room temperature, it will become dry and stale.

The best way to store it is in the freezer, so we highly recommend it.

By freezing the bread, the tangy flavor of the sourdough bread will be preserved.

How To Freeze Sourdough Bread?

You can easily put your baked sourdough bread inside a freezer-safe Ziploc bag if you plan to freeze it for some days or weeks.

In order to prevent spoilage, you should remove as much air as possible.

Make sure you place it inside a freezer compartment that won’t crush it once you decide to put it in.

If you plan to freeze your bread for a long period of time, you will need to take additional steps to ensure that its quality is protected.

The following are key points you should keep in mind:

  • You must ensure that the bread has cooled completely to room temperature.
  • Using plastic wrap, wrap the entire loaf of bread.
  • The second layer of protection should be made by wrapping it in aluminum foil. Each and every opening must be completely closed.
  • If you want to freeze the plastic and foil-wrapped bread, you can place it in a large Ziploc bag. Make sure it is tightly sealed.
  • Be sure to label the bag with the freezing date. Tracking how long the item has been in the freezer will help you monitor its condition.

In this case, the method we discussed above will be perfect for a whole loaf of bread.

Bread that has been cut will also work.

If you want to slice sourdough bread, you will need to follow a different procedure.

Separate pieces of bread of different sizes can be frozen quite easily.

This will save you the trouble of having to thaw an entire loaf when you want to make a sandwich.

Here are the steps you can take:

  • Your sourdough bread needs to be sliced into multiple pieces first.
  • Sandwich-size Ziploc bags should be filled with 1-2 slices of your sourdough bread. Make sure they are tightly sealed.
  • Make sure they are sized conveniently to avoid air trapping spaces or gaps.

There are times when sandwich bags can’t be frozen.

To get extra protection, you can put all the small sandwich bags in a large freezer bag once they have been separated.

For another method, here’s what you need to do:

  • Place them on a baking sheet and spread them out. A single layer of parchment paper needs to be placed on the baking sheet before you begin baking.
  • Using plastic wrap, cover the bottom layer if there is more than one layer. Continue by adding another layer on top.
  • Separate the pieces of bread and let them freeze completely. You shouldn’t have to wait more than an hour.
  • After they have been separately frozen, place them all in a large freezer-safe Ziploc bag. This will prevent them from sticking together.
  • It’s now time to put them in the freezer.

You can store sourdough bread in your freezer for up to six months.

You can even prolong its duration if you take proper care of it.

You should always eat frozen food as soon as possible, just like any other food.

How To Thaw Frozen Sourdough Bread?

The following three methods are available to you:

1 – Using Your Oven.

  • The first step is to start unwrapping and removing the plastic wrap.
  • Once this is done, you can place it inside your oven at a low temperature.
  • You should set the temperature exactly at 2000F.
  • Over 30 minutes should be enough time to heat it. It is also important to consider the size of your sourdough bread when determining the heating time.
  • Let it cool on your kitchen counter after you take it out.

2 – Using Your Fridge.

  • You can transfer it from the freezer to the refrigerator.
  • Make sure that your bread is wrapped and sealed properly. This will prevent moisture from getting inside your bread during condensation.
  • Unwrap the frozen food and eat it once it thaws out.

3 – Using Your Toaster or Pan.

To slice sourdough bread using this method, follow these steps:

  • Remove them from the freezer and place them in a toaster or frying pan.
  • Put them on low heat and begin heating them.
  • Let them cool for a few minutes before eating.


  • Defrosting your oven, toaster, or pan at high temperatures is not recommended.
  • Remember to remove all the air from your sourdough bread before you put it back in the freezer.


The taste of sourdough bread is quite good, and it is also quite easy to make.

Furthermore, it has many antioxidants, such as peptides, which reduce the risk of cancer and rheumatoid arthritis.

In addition, the human body is able to digest this bread more easily than others.

Its tangy flavor is complemented by its chewy and crispy texture, making it ideal for pairing with almost any dish.

It takes a long time to make this bread, but the taste is worth the effort.

Baking them yourself and freezing them for later use is an option.
