If you’ve got extra sourdough starter sitting around, I’ve got the perfect recipe for you: Sourdough Granola!

It’s crunchy, lightly sweet, and has just a hint of tang from the starter. You can customize it with your favorite nuts, seeds, or dried fruit, and it’s ready in under 30 minutes. We love snacking on it by the handful, layering it over yogurt bowls, or packing it into snack bags and school lunches!

If you enjoy the tangy flavor of sourdough, you’ll love the subtle hint it brings to this granola. It’s easy to customize with your favorite mix-ins like nuts, seeds, and dried fruit.

Prefer it sweeter? Just add a bit more maple syrup or a sprinkle of sugar.

You can break the granola into big clusters or smaller bits, whatever suits your snacking style. Enjoy it on its own, over yogurt bowls, packed into snack bags, school lunches, or however you like!

Amy’s Notes

Amy Duska in a kitchen.

I’ve made this sourdough granola more times than I can count, it’s a favorite in our house! You can use either sourdough discard or active starter, depending on what you’ve got on hand.

It bakes up golden and crisp, lightly sweet, and perfect for breakfast or snacking. Let it cool completely before breaking it into clusters so it stays nice and crunchy.

Feel free to switch up the add-ins; pumpkin seeds, shredded coconut, or chopped nuts all work beautifully.

And if it starts browning too quickly, just lower the oven temp. Stored in an airtight container, it stays crisp for up to two weeks… though it never lasts that long around here!
