If you’re a fan of sourdough but don’t want to feed your starter every day, dehydrating it is a great option. It’s an easy way to store your starter for the long term, and when you’re ready to bake again, you can simply rehydrate it. Whether you’re going on vacation, taking a baking break, or just want a backup, dehydrating your starter is a foolproof way to make sure it’s ready when you need it. Here’s an easy way to dehydrate your sourdough starter. Follow this simple, step-by-step guide on how to do it!

Why Dehydrate Your Sourdough Starter?
Dehydrating your sourdough starter is a great idea if you want to have a backup plan in place. It’s super convenient because once it’s dried, you don’t have to feed it daily—just store it in an airtight container, and it’s good for months! Plus, if anything happens to your active starter (life gets busy, you forget to feed it, etc.), you’ll always have a preserved version ready to be rehydrated and brought back to life. It’s like giving your starter a little nap until you’re ready to bake again!
How to Dehydrate Starter
Here’s how to dehydrate your starter in a few easy steps:
- Feed your starter: Start by giving your sourdough starter a fresh feeding. Make sure it’s active and bubbly before dehydrating. You want it to be in its best condition before drying it out.
- Spread it thin: Once your starter is active, spread a thin layer on a piece of parchment paper if you are using a dehydrator.
- A silicone mat or a baking sheet works perfectly if you don’t have a dehydrator.
- Let it dry: If you’re using a dehydrator, place your parchment paper with starter on it into the dehydrator and turn it on. Keep it running until the starter is dry and crumbles easy.
- Leave the starter in a warm, dry place if you aren’t using a dehydrator. It will take anywhere from 1-3 days to fully dry, depending on the temperature and humidity. The starter is ready when it’s completely dry and brittle.
- Break it up: Once the starter is dry, break it into small pieces. You can crush it by hand or use a food processor to create a fine powder.
- Store it safely: Put your dehydrated starter in an airtight container or resealable bag. Make sure to label it with the date. Store it in a cool, dry place, and it will be good for months!
How to Rehydrate Your Starter
When you’re ready to use your starter again, rehydrating is simple:
- Mix equal parts of dehydrated starter and water (for example, 1 tablespoon of each) in a small bowl.
- Let it sit for a few hours until the starter softens and begins to dissolve.
- Start feeding it like you would a fresh starter—give it some flour and water, and within a few feedings, it’ll be back to its bubbly, active self!
Final Thoughts
Dehydrating your sourdough starter is a great way to ensure it’s always ready when you need it, without the daily upkeep. It’s a simple process that gives you peace of mind, knowing your beloved starter is safely stored away for the next time you’re ready to bake. Happy baking!
