If you are wanting to maintain your sourdough starter with a zero waste sourdough discard routine, then this is the blog for you! Discard is essential to building a thriving sourdough starter, but you don't have to throw it away!
If you are keeping your sourdough starter on your bench and feeding it regularly, you can accumulate a lot of discard quite quickly.
A lot of people baulk at "discarding" half your starter every time you feed it, however it is a necessary part of the sourdough process. But just because you are removing the "discard" from your starter jar, doesn't mean you have to waste it.
If you want to cut down on the amount of discard you produce, you can keep your mature starter in the fridge - but even then, you will still have a bit of discard to deal with.
You could also maintain a much smaller starter and then build what you need each time you bake.
But half the fun of maintaining a sourdough starter is finding creative ways to use the discard, right?
IMPORTANT NOTE - I advise not to use your sourdough discard for the first 5 to 7 days of building your sourdough starter. During this time the good bacteria are fighting it out for dominance and the yeast colonies are still being established. It usually smells really bad in these first few days. Put this early discard into the bin or compost.
Zero Waste Sourdough Discard
There are lots of interesting and delicious ways to use your sourdough discard instead of tossing it in the bin. Here are 17+ uses that will ensure your sourdough starter is never wasted.
Dry Your Sourdough Discard
There are so many uses for dried sourdough starter discard, many of which you probably haven't thought of. Now remember discard is unfed starter that you are removing from the jar when you go to feed it.
Take your discard and smear it onto some baking paper and let it dry on your kitchen bench or even in a dehydrator at a low temperature (it really doesn't take long). Once the discard is completely dry, blitz it in a high powered food processor (I use my Thermomix). Now you've got a nutrient rich, probiotic filled powder that you can use for a variety of purposes:
- Use it as "flour" and add to cakes, muffins, pizza - even your bread!
- Use it as a crunchy topping for salads, pasta or soup
- Add it to your breadcrumbs for crumbing chicken or fish
- Use it as a delicious crunchy topping for roast potatoes
- Mix it with some nutritional yeast to make vegan parmesan
Make a Sourdough Discard Batter
Traditional batter is just flour and water ... and isn't that what sourdough discard is? So it makes sense to use your discard as a batter! There are a few ways you can jazz it up.
To use your sourdough starter as batter, add ¼ teaspoon of baking soda to 100g of discard. Give it a mix and add any flavourings you might like - then coat your food and fry. If you want to make your batter go a little further, you can add a little soda water and extra flour - whisk with a fork until it's like runny pancake batter.
You could add a little curry powder to some batter and fry fish. A little cinnamon and fry some banana. Paprika could be a good addition to chicken.

Sourdough discard can also be added to your worm farm too.
