Sourdough Discard Granola (Clean, Crispy, and Easy)

The clean snack I make all summer to use up extra discard

If you bake sourdough, you already know the truth nobody warns you about when you start your starter: the discard adds up. There is almost always a jar of it sitting in my fridge, and some weeks there is a lot of it.

This recipe started as a simple way to use it up. But like most of the food in our house, it traces back to a bigger story.

When my boys were little, we walked through the GAPS protocol, the Gut and Psychology Syndrome diet, to heal their food allergies. For a long stretch, our world got very small. I read every single label. I made almost everything from scratch. And there was a long list of foods that simply were not safe in our house.

Cashews were one of them.

I still remember the first time my boys could eat cashews. I cried, standing right there in my kitchen, watching them eat a handful of nuts like it was the most ordinary thing in the world, because I knew exactly how far we had come to get to that moment.

So when I tell you this granola is full of nuts and seeds, know that it is not a throwaway snack to me. It is a small, crunchy reminder that healing is possible, and that real food can be both simple and a little bit sacred. Now it is something I make all summer long, a quick and portable snack that keeps everyone fed through our very busy baseball schedule.

Why Sourdough Discard Belongs in Granola

Most granola recipes use oats or oil to hold everything together and give you those crave-worthy clusters. Sourdough discard does that job beautifully. It acts as the base that coats the nuts and seeds, helps everything clump, and crisps up into golden, crunchy clusters in the oven. You get structure and crunch without anything processed, and you put your discard to work instead of pouring it down the drain.

It also adds the faintest tang in the background, which plays really nicely against the maple and chocolate. You are not making sourdough bread here, so do not overthink it. If you have discard, you can make this.

The Ingredients I Use (and Why)

I want to be honest with you: I do not really measure this. I go by feel, and after a little trial and error, this is roughly where I land. Treat these as a starting point, not a rulebook. The whole point is to use clean, simple ingredients you can pronounce and feel good about.

Sourdough discard

About 150 grams, straight from the fridge. This is the base that brings everything together.

Nuts

About three-quarters of a cup of chopped cashews and almonds. Use whatever combination you love. Cashews will always be the special one in this house.

Seeds

About a third of a cup of hemp seeds, plus about a third of a cup of a salted pumpkin and sunflower seed mix. Seeds add protein, crunch, and staying power, which is exactly what you want in a snack that has to hold up to a long day.

Sweetener

About 50 grams of maple syrup. Honey works just as well and gives you a slightly different flavor, so use whichever you have on hand. Both are great.

Salt

Just a little, and go easy. The pumpkin and sunflower seed mix and the cashews are usually already salted, so you do not need much.

Chocolate chips

About a third of a cup of Hu coconut sugar chocolate chips. They keep the ingredient list clean without skipping the part everyone actually reaches for first.

How to Make Sourdough Discard Granola

Ingredients

Instructions

  1. Add everything to a bowl and mix until the discard coats the nuts and seeds.
  2. Line a baking sheet with parchment paper and spread the mixture out in an even layer.
  3. Bake at 275 degrees for 20 minutes.
  4. Pull it out, break it apart, and flip the pieces over. The smaller you break them, the crispier your granola will be.
  5. Return it to the oven for another 15 to 20 minutes, until the edges are golden brown.
  6. Let it cool completely so it can finish crisping, then store in an airtight container.

Tips for the Crispiest Granola

Low and slow is the secret. A 275 degree oven dries the granola out gently so it gets crisp instead of burnt. Keep an eye on the edges toward the end, because that is where it browns first.

And remember, the size of the pieces decides the crunch. If you like fine, snackable bits, break it up small when you flip it. If you want big clusters to put on yogurt, leave the pieces bigger and handle them gently.

How We Actually Eat It

Most of the time it gets eaten by the handful, straight out of the container, on the way to a game. It is also wonderful over a bowl of homemade yogurt or kefir, or scattered on top of fruit. It travels well, it does not melt, and it keeps everyone happy between innings, which in this season is exactly what I need from a snack.

Make It Your Own

This is the kind of recipe that is begging to be personalized. Swap the nuts, change the seeds, use honey instead of maple, add a little cinnamon or a handful of shredded coconut. There is no wrong way to do it as long as you are starting with real ingredients you trust.

If you make it, come tell me what you added. I genuinely love hearing the combinations you come up with, and your idea might just become the next batch in my kitchen.

Sourdough Discard Granola FAQ

Can I use sourdough discard straight from the fridge?

Yes. Cold discard works perfectly. There is no need to bring it to room temperature or feed it first. This is a use-it-up recipe, so whatever is in the jar is exactly what you want.

Does it taste sour?

Not really. You get the faintest tang in the background, which actually balances the maple and chocolate. It tastes like granola, not like sourdough bread.

How long does it keep?

Stored in an airtight container, it stays crisp for one to two weeks. In our house it rarely makes it past a few days, especially during baseball season.

Can I make it nut-free?

Yes. Swap the cashews and almonds for extra seeds, like more pumpkin and sunflower, or a sunflower seed butter drizzle. The discard still does the work of holding it all together.

Why is my granola not crispy?

Two usual culprits. Either the pieces were too big when you flipped them, or it needed a few more minutes. Break it smaller, keep the oven low at 275, and give it the full second bake until the edges are golden. It also crisps up more as it cools, so let it sit before you judge it.
