How to Dry a Sourdough Starter for Easy Storage
Tina BevkAre you looking to preserve your beloved sourdough starter without the daily hassle of feedings? Drying your sourdough starter is a brilliant method for long-term storage, ensuring you have your trusty starter ready whenever the baking urge strikes.
Here’s a simple, step-by-step guide to drying your sourdough starter that I use when I want to have some on hand when disasters strike (and by disasters, I mean husbands turning the oven on when you have your starter jar there).

How to Dry a Sourdough Starter
Equipment
- 1 parchment paper
- 1 Cookie sheet
- 1 airtight jar, airtight container, or zip-top bag
Ingredients
- 100 grams sourdough starter active and bubbly
Instructions
- Prepare Your Starter. Begin with a well-fed, bubbly sourdough starter. If it’s been a while since you last fed it, give it a good feed and wait until it’s active and full of bubbles.
- Spread It Out. Line a baking sheet with parchment paper. With a spatula, spread your sourdough starter thinly across the paper. The thinner the layer, the quicker it will dry.
- Let It Dry. Place the baking sheet in a warm, dry area with good airflow. A sunny spot on the countertop or a barely warm oven (turned off) with the door slightly open can work well. Allow the starter to dry completely; this can take anywhere from 24 to 48 hours, depending on the conditions in your kitchen.
- Break It Up. Once fully dry, the starter should be brittle and easy to crack. Break it into small flakes or grind it into a powder. Smaller pieces will rehydrate more quickly when you're ready to revive them.
- Store It Safely. Transfer the dried sourdough flakes or powder into an airtight container, mason jar, or a sealed zip-top bag – a Mason jar is my preference. Keep it in a cool, dry place. Properly stored, your dried starter can last for months, even years!
Notes
- Rehydrate the Starter: Mix 1 tablespoon of dried starter with 50 ml of lukewarm water until dissolved.
- Feed the Starter: Add 50 grams of flour to the mixture, stir until smooth, and let it sit in a warm spot, covered loosely.
- Feed Regularly: Every 12 hours, discard half and feed with equal parts of flour and water by weight (e.g., 30 grams each).
- Watch for Activity: Look for bubbling and growth. Continue feeding until the starter doubles in size within 4 to 6 hours after feeding.
- Bake or Store: Once active, use your starter for baking, or store it in the refrigerator and feed it weekly.
