Sourdough Discard Recipes: 7 Easy Ways to Use Your Leftover Starter

If you keep a sourdough starter, sooner or later you’re going to have sourdough discard.

New to sourdough? Read our Your Sourdough Starter: 10 Questions Every New Baker Asks guide for practical answers on feeding, flour, storage and knowing when your starter is ready to bake with.

And if you’re anything like most bakers, the first few times you tip perfectly good flour into the bin, it doesn’t feel right.

The good news?

You don’t have to throw it away.

Sourdough discard can be used in pancakes, crackers, pizza bases, muffins, flatbreads and plenty of other recipes. It adds flavour, reduces waste and gives you another reason to bake.

Here are 7 easy sourdough discard recipes and ideas that every home sourdough baker should have up their sleeve.

First: What Is Sourdough Discard?

Sourdough discard is simply the portion of starter you remove before feeding your remaining starter with fresh flour and water.

Why remove some?

If you kept adding flour and water without removing any starter, you’d soon have an enormous jar and would need increasingly large amounts of flour to feed it.

Discarding keeps your starter at a manageable size and helps maintain an appropriate feeding ratio.

But the word “discard” is slightly misleading.

It doesn’t necessarily belong in the bin.

Once you have a healthy, established starter, that leftover flour and water can become an ingredient in its own right.

Can You Bake With Sourdough Discard?

Absolutely.

The important thing to understand is that discard isn’t necessarily the same as an active sourdough starter.

An active starter is generally used around its peak when the yeasts and bacteria are active and producing plenty of gas.

Discard may have passed that point, so recipes using discard often rely on baking powder, baking soda, yeast or eggs for additional lift.

What discard does bring is flavour.

That slight sourness can add another dimension to both sweet and savoury baking.

A Quick Food-Safety Note

Only save discard from a healthy starter.

If your starter has visible mould or unusual pink, orange or other suspicious discoloration, don’t use the discard.

Throw it away and start again.

Now, let’s get baking.

1. Sourdough Discard Pancakes

This is probably one of the easiest places to start.

Sourdough discard adds a lovely slight tang to pancakes and works particularly well for a weekend breakfast.

Ingredients

  • 150g sourdough discard
  • 150g plain flour
  • 250ml milk
  • 1 egg
  • 30g melted butter
  • 20g sugar
  • 2 teaspoons baking powder
  • ½ teaspoon salt

Method

Whisk the egg, milk, melted butter and sourdough discard together.

In a separate bowl, combine the flour, sugar, baking powder and salt.

Add the wet ingredients to the dry ingredients and mix gently until just combined. Don’t worry about a few small lumps.

Let the batter rest for around 10 minutes.

Cook in a lightly greased frying pan over medium heat until bubbles appear on the surface. Flip and cook until golden.

Serve warm with butter, honey, maple syrup or fresh fruit.

Baker’s tip: Don’t overmix pancake batter. A gentle mix will give you a softer pancake.

2. Crispy Sourdough Discard Crackers

If you’ve never turned sourdough discard into crackers, try it.

They’re incredibly simple and a great way to use up a small amount of discard.

Ingredients

  • 200g sourdough discard
  • 30g olive oil
  • ½ teaspoon salt
  • Herbs, seeds or spices of your choice

Try rosemary, sesame seeds, cracked pepper, garlic, parmesan or everything-bagel seasoning.

Method

Preheat your oven to 170°C.

Mix the discard, olive oil and salt together.

Spread the mixture very thinly onto a sheet of baking paper on a baking tray.

Sprinkle your chosen toppings over the surface.

Bake for approximately 10 minutes, then remove from the oven and score into cracker-sized pieces.

Return to the oven and bake until crisp and golden.

Allow them to cool completely before storing.

The secret is thickness: the thinner you spread the mixture, the crispier your crackers will be.

3. Sourdough Discard Pizza Base

Pizza is a brilliant place to use sourdough discard because a little fermentation flavour works beautifully with a crisp, savoury crust.

Ingredients

  • 150g sourdough discard
  • 350g bread flour
  • 180–200g water
  • 7g salt
  • 5g instant dry yeast
  • 15g olive oil

Method

Combine the sourdough discard, water and yeast.

Add the flour and mix until a rough dough forms.

Add the salt and olive oil and knead until reasonably smooth.

Cover and allow the dough to rise until noticeably increased in volume.

Divide and shape into pizza bases.

Add your favourite toppings and bake in the hottest oven you can manage, preferably on a preheated pizza stone or steel.

The commercial yeast provides reliable lift while the discard contributes additional flavour.

It’s a great combination when you want sourdough character without waiting for a long sourdough fermentation.

4. Sourdough Discard Flatbread

This might be the easiest discard recipe of all.

Ingredients

  • 200g sourdough discard
  • 150g plain flour
  • 80g Greek yoghurt
  • 15g olive oil
  • ½ teaspoon salt

Method

Mix everything together until a soft dough forms.

Rest for approximately 20–30 minutes.

Divide into small portions and roll each piece thinly.

Cook in a hot, dry frying pan for a couple of minutes on each side until browned and slightly puffed.

Brush with olive oil or melted butter while warm.

Add garlic and herbs and you’ve got a fantastic accompaniment to dinner.

5. Sourdough Discard Banana Muffins

Discard isn’t just for savoury recipes.

The slight acidity works beautifully in cakes and muffins.

Ingredients

  • 150g sourdough discard
  • 2 ripe bananas, mashed
  • 200g plain flour
  • 100g brown sugar
  • 100g melted butter
  • 2 eggs
  • 1 teaspoon baking soda
  • 1 teaspoon cinnamon
  • ½ teaspoon salt
  • 1 teaspoon vanilla

Method

Preheat your oven to 180°C.

Whisk the bananas, discard, eggs, melted butter and vanilla together.

Combine the flour, brown sugar, baking soda, cinnamon and salt in another bowl.

Gently combine the wet and dry mixtures.

Spoon into a lined muffin tray and bake for approximately 18–22 minutes, or until a skewer inserted into the centre comes out clean.

Chocolate chips or walnuts?

We won’t judge.

6. Sourdough Discard Waffles

If pancakes are good, sourdough waffles might be even better.

The acidity and flavour of the discard work particularly well when the outside becomes crisp in the waffle iron.

Ingredients

  • 200g sourdough discard
  • 150g plain flour
  • 250ml milk
  • 2 eggs
  • 50g melted butter
  • 20g sugar
  • 2 teaspoons baking powder
  • ½ teaspoon salt

Method

Mix the discard, milk, eggs and melted butter.

Combine the dry ingredients separately.

Gently mix everything together and allow the batter to rest for about 10 minutes.

Cook according to your waffle maker’s instructions.

Serve immediately while they’re beautifully crisp.

7. Sourdough Discard Herb & Cheese Scones

Here’s one for the savoury bakers.

Ingredients

  • 150g sourdough discard
  • 300g self-raising flour
  • 60g cold butter
  • 100g grated cheddar cheese
  • 100–120ml milk
  • ½ teaspoon salt
  • Chopped herbs to taste

Method

Preheat the oven to 200°C.

Rub the cold butter into the flour until the mixture resembles coarse breadcrumbs.

Add the cheese, herbs and salt.

Stir through the sourdough discard and enough milk to form a soft dough.

Turn onto a lightly floured surface and gently bring the dough together.

Don’t overwork it.

Cut into rounds and place on a lined baking tray.

Bake until risen and golden.

Serve warm with butter.

They’re especially good when you tell everyone you made them because you were “trying to reduce waste”.

How Long Can You Keep Sourdough Discard?

If you’re not ready to use your discard immediately, keep it in a clean, covered container in the refrigerator.

Many bakers keep adding discard to the same refrigerated container and use it when they have enough for a recipe.

However, remember that discard continues to change as it ages.

It becomes increasingly acidic and its flavour becomes stronger.

For the best results, use your judgement and don’t keep questionable discard simply because you don’t want to waste it.

If you see mould or unusual discoloration, throw it away.

When in doubt, don’t use it.

Can You Freeze Sourdough Discard?

Yes.

If you’re producing more discard than you can reasonably use, freezing it is another option.

Portion it into useful quantities — for example, 100g or 200g portions — so you can defrost exactly what you need for a recipe.

Label it with the date and quantity before freezing.

Our Favourite Way to Think About Discard

Here’s the thing:

Discard isn’t really waste until you waste it.

Once you start looking at it as an ingredient rather than something destined for the bin, maintaining a sourdough starter becomes much more interesting.

Today’s starter feed can become tomorrow’s pancakes.

Or crackers.

Or pizza.

Or muffins.

And that’s one of the things we love about sourdough: one simple mixture of flour and water can take you in so many different directions.

Your Sourdough Starter: 10 Questions Every New Baker Asks

There is a moment almost every new sourdough baker remembers.

You mix flour and water, put the jar on the bench… and then what?

For the next few days, you check it, sniff it, watch for bubbles and wonder whether you’ve done something wrong.

You probably haven’t.

A sourdough starter is a living culture of wild yeasts and bacteria, and getting to know how it behaves is part of learning to bake sourdough.

These are 10 of the most common sourdough starter questions we hear from home bakers — and the practical answers we’d give you.

1. What Exactly Is a Sourdough Starter?

A sourdough starter is essentially flour and water fermented by naturally occurring yeasts and bacteria.

These microorganisms feed on nutrients in the flour and produce gases and organic acids during fermentation.

The gas helps your bread rise, while fermentation contributes to sourdough’s distinctive flavour and aroma.

You’re not creating anything particularly complicated. You’re simply giving a natural fermentation process the right environment, regular food and enough time to establish itself.

2. How Often Should I Feed My Sourdough Starter?

It depends on your starter, your feeding ratio and, importantly, the temperature of your kitchen.

A healthy, active starter kept at room temperature may need feeding once or even twice a day, particularly in warmer conditions.

In a cooler kitchen, fermentation will generally happen more slowly.

Rather than relying entirely on the clock, learn to watch your starter.

After feeding, it should begin bubbling and rising. Eventually it will reach its peak and then start to fall.

Once you’ve looked after the same starter for a while, you’ll begin to recognise its rhythm.

3. What Is the Best Flour for a Sourdough Starter?

The good news is that you don’t need a special “starter flour”.

A quality bread flour, wholemeal flour or rye flour can all be used to establish and maintain a sourdough starter.

Wholegrain and rye flours are particularly popular when establishing a new starter because they contain more of the grain and can encourage fermentation activity.

Once your starter is established, you can continue feeding it with wholegrain flour or transition to a good-quality white bread flour for a more predictable routine.

At Basic Ingredients, we’re big believers in choosing flour according to what you’re trying to bake rather than assuming one flour is perfect for everything.

4. Why Does My Sourdough Starter Smell Strange?

Sourdough starters develop a surprisingly wide range of aromas.

Depending on its age, temperature and feeding cycle, your starter might smell:

  • Fruity
  • Yeasty
  • Tangy
  • Yoghurt-like
  • Vinegary
  • Slightly alcoholic
  • Occasionally similar to acetone or nail polish remover when very hungry

A strong acidic or acetone-like smell can be a sign that your starter needs feeding.

However, there is an important distinction between a hungry starter and a contaminated starter.

If you see visible mould or unusual pink or orange discoloration, don’t simply feed it and hope for the best. Discard it, thoroughly clean your equipment and start again.

5. Why Is There Liquid on Top of My Sourdough Starter?

You may occasionally find a layer of liquid sitting on top of a neglected or hungry starter.

This is commonly referred to as “hooch” and can contain alcohol produced during fermentation.

It’s usually a sign that your starter has been sitting for some time and needs fresh food.

You can pour the liquid off or stir it back through before feeding. Stirring it through may contribute to a more acidic flavour.

Then give your starter a proper feed and allow it to become active again.

6. Why Is My Sourdough Starter Not Rising?

Don’t panic.

A sourdough starter that’s not rising isn’t necessarily dead.

New starters can go through periods where they appear extremely active followed by several surprisingly quiet days. This can be part of the normal process of establishing a stable culture.

Temperature can also make an enormous difference.

A starter sitting in a cold kitchen will generally ferment much more slowly than one kept somewhere comfortably warm.

Give it fresh flour and water, keep it at a suitable temperature and give it time.

If you’re consistently seeing no activity, review your feeding ratio, flour, water and temperature before giving up.

7. How Do I Know When My Sourdough Starter Is Ready to Bake With?

This is one of the biggest questions for new sourdough bakers.

A mature starter should rise predictably after feeding and show plenty of fermentation activity.

Look for:

  • Consistent rising after feeds
  • Plenty of bubbles throughout the starter
  • A pleasant fermented aroma
  • A predictable rise and fall cycle

You’ve probably heard about the sourdough float test: dropping a spoonful of starter into water and seeing whether it floats.

It’s a handy observation, but don’t rely on it as your only test.

A starter can be perfectly capable of making bread and still fail the float test. Consistent fermentation and predictable rising are much better indicators of starter strength.

8. Can I Keep My Sourdough Starter in the Fridge?

Absolutely.

For home bakers who aren’t making sourdough every day, refrigeration makes maintaining a starter much easier.

The cold dramatically slows fermentation, which means you don’t have to maintain the same feeding routine as a starter kept permanently at room temperature.

Many bakers feed a refrigerated starter approximately once a week, although the ideal schedule can vary.

When you’re planning to bake, remove your starter from the fridge and give it time to become active again. Depending on its condition, one or more room-temperature feeds may be helpful before mixing your dough.

9. Do I Really Have to Discard Sourdough Starter?

Discarding isn’t simply about throwing flour away.

If you continually add flour and water without removing any starter, your jar will quickly become enormous and you’ll need increasingly large quantities of flour to maintain an appropriate feeding ratio.

Removing some starter keeps the quantity manageable and makes feeding easier.

Better still, sourdough discard doesn’t necessarily have to go in the bin.

Try using it in:

  • Pancakes
  • Waffles
  • Crackers
  • Flatbreads
  • Muffins
  • Pizza dough
  • Cakes and other baked goods

Just remember that discard isn’t necessarily being used for its leavening power in these recipes.

10. Why Does My Sourdough Starter Keep Failing?

If your sourdough starter isn’t behaving as expected, don’t immediately blame yourself — or the flour.

Work through the basics systematically.

Check:

Temperature: Is your kitchen particularly cold or excessively hot?

Feeding ratio: Are you giving the culture enough fresh flour and water?

Timing: Are you feeding before the starter has had enough time to ferment?

Flour: Are you using fresh, good-quality flour?

Water: If your water is heavily treated, trying filtered water may be worthwhile.

Consistency: Are you changing flour, feeding ratios and temperatures constantly?

Sourdough rewards consistency.

Change one thing at a time, observe what happens and learn how your particular starter behaves.

And if you genuinely need to start again?

That’s okay too.

Every starter teaches you something.

The Honest Bottom Line

Sourdough doesn’t need to be as complicated as the internet sometimes makes it sound.

Flour. Water. Fermentation. Time.

Learn when your starter is hungry. Keep it at a sensible temperature. Feed it consistently. And don’t panic every time it behaves a little differently.

Most importantly, remember that sourdough isn’t about producing an Instagram-perfect loaf every time. It’s about understanding your ingredients and learning how fermentation behaves in your own kitchen.

And good bread always starts with good ingredients.

How To Create Steam In Your Oven

Bread baked in an oven can be enhanced by creating steam in the oven. The steam will help “seal in” the crust, to make it become crispier.

Place an old skillet, or any metal vessel at the bottom of the oven before turning it on. Crank your oven up to 230°C + if you can. For even better results fill it with some old nuts, screws or bolts.

Once the proven dough has been placed in the oven, pour 100-200ml of hot/warm water over the tray. This will create plenty of steam!

After 10 minutes, open the oven door for 5-10 seconds to vent the oven, as by now any moisture will be detrimental for further crust development.

Lower the oven to 190-200° to finish your baking.

How To Store Flour

Just as it is impossible to guarantee you will never get a flat tyre, the same applies to bread flour. We cannot guarantee our flour will never have insects.

By storing flour correctly however, you can greatly reduce the chance of flour contamination.

If used within 6-8 weeks, product should be fine in the packaging it came in. (some products such as yeast, improvers should be refrigerated in airtight containers), If kept longer, store (part) of your flour in airtight containers, in the coolest spot in your house. Even better in the fridge or freezer!

In summer it is advisable to only buy enough flour that will last you about 5-6 weeks. If you think you will keep flour longer than that, keep (part of) it in the fridge or freezer.

The life cycle of most pests is approximately 20 days. It is a fairly safe bet that insect activity that is observed more than 4 weeks after a product has been purchased has commenced in the pantry, rather than been in the product at purchase.

Placing products in the freezer for two days will kill and eliminate a great deal of a potential problem.

Particularly in summer, routinely place newly bought product in the freezer before storage in the pantry is extremely effective and well worth allocating some freezer space for that use.
