If you’re looking for a practical sourdough crackers recipe, this is one you’ll come back to again and again. Many sourdough discard recipes are more fun than they are useful. Most cakes and muffins only use a small amount of discard—typically 1/4 to 1/3 cup—so they don’t help much when you have a full cup (or more) sitting in your fridge.

Don’t get me wrong—I love a good sourdough treat like my sourdough blackberry muffins or discard coconut cake. But let’s be honest: most discard recipes are just an excuse to make more cake.

This sourdough crackers recipe is my go-to when I need to use up a lot of discard. It uses a full cup and can be easily doubled if you have even more to use—something that happens often when life gets busy and feeding your starter slips down the list.

What makes this recipe even better is how simple it is. It takes just 5 minutes to prep, so you’re not spending extra time in the kitchen just to use up discard. That’s exactly why “easy” is in the title—I’ve intentionally kept this method as quick and fuss-free as possible.

When it comes to saving time and reducing waste, sourdough crackers really are the way to go. Let me show you how to make them.

What Are Sourdough Crackers?

Sourdough crackers are thin, crispy crackers made from sourdough starter or discard, a little fat (I like to use olive oil or melted butter), and simple seasonings. Some sourdough crackers recipes include additional flour and require rolling out the dough, but in this sourdough crackers recipe, I keep things intentionally simple.

There’s no rolling, no extra steps—just mix, spread, and bake. It’s designed to be quick and manageable, even on your busiest days, without adding extra work to your schedule.

These crackers are an easy way to use up discard while creating a naturally fermented, flavorful snack your whole family will enjoy.

Are Sourdough Crackers Healthy?

Yes—this sourdough crackers recipe can make a wonderfully wholesome snack. Because it uses fermented starter, it may be easier to digest, and you have full control over the ingredients—already a big step up from most store-bought snacks.

That said, how healthy your crackers are really depends on what you put into them. The quality of your flour, fats, and salt all make a difference.

To boost the nutrition, I like to use my favorite 50% whole wheat starter, along with good-quality olive oil (or melted butter) and unrefined salt. Simple ingredients, but they come together to make something both nourishing and satisfying.

Ingredients

You can use either active starter or unfed discard straight from the fridge in this sourdough crackers recipe—both work equally well, so use whatever you have on hand.
I usually reach for olive oil because it makes prep quicker, but melted butter works just as well and adds a lovely flavor.
Feel free to swap the onion and garlic powders for 1 teaspoon of your favorite herbs or spices to suit your taste.

Tools You’ll Need

You only need a few simple tools to whip up a batch of these sourdough crackers

Medium mixing bowl
Baking sheet
Parchment paper
Pizza cutter or sharp knife

How to Make Sourdough Crackers Step-By-Step

Step 1

Preheat your oven to 325°F (165°C) and line a baking sheet with parchment paper. Add the sourdough discard to a medium mixing bowl.

Step 2

Sprinkling salt and spices on top of discard in bowl

Sprinkle in the fine salt, onion powder, and garlic powder. Alternatively, you can swap the onion and garlic for your favorite spice blend.

Step 3

Add in olive oil or melted butter.

Step 4

Mixing together the ingredients for sourdough crackers in a bowl

Stir everything together until smooth. The mixture should resemble a thick pancake batter. If it’s too thick to spread, add water one teaspoon at a time until you reach a thick but spreadable consistency.

Step 5

Spreading the batter for sourdough crackers recipe on a baking sheet lined with parchment

Pour the batter onto the center of your lined baking sheet and use the back of a spoon or a spatula to spread it as thinly as possible—almost see-through in some spots.

Spreading the batter thin is key to crispy crackers, while thicker batter will result in crackers that are more chewy than crisp.

Step 6

Prebaking the sourdough crackers in the oven

Bake for about 10 minutes, until the surface looks dry and set, but not fully browned.

Step 7

Scoring sourdough crackers with a pizza cutter

Remove the tray from the oven and use a pizza cutter or a knife to score the dough into cracker shapes, such as squares or diamonds. If using a knife, choose one with a smooth blade rather than a serrated edge.

Step 8

Return the tray to the oven and bake for another 10–15 minutes, until the crackers are deep golden and fully dry in the center. To check for doneness, tap a cracker with your fingernail—it should feel crisp, not soft.

Step 9

Removing some of the ready crackers into a bowl

The edges usually brown faster, so I like to remove those crackers first. Then I return the tray to the oven for a few more minutes so the center crackers can finish crisping up evenly.

Step 10

Once fully cooled, break the crackers apart. They will continue to crisp up a bit as they cool.

Serving Ideas

Sourdough crackers are wonderfully versatile, so you can serve them alongside both simple and more fancy foods:

Pair with a cheese board—soft cheeses like goat cheese or cream cheese, or a sharp aged cheddar for contrast. I’ve loved cheese boards ever since living in Scotland, and these crackers make a wonderful alternative to the traditional oatcakes served with cheese there.
Serve with dips like hummus, sour cream with herbs, or homemade yogurt-based spreads. We especially love dipping these crackers into homemade cottage cheese—so simple and good.
Use as a base for easy appetizers—top with sliced cucumber, smoked fish, or a spoonful of egg salad. My personal favorite is crackers with smoked mackerel spread (yum!).
Add a sweet twist with honey, fruit preserves, or nut butter for a quick snack.
Serve alongside soups or salads as a crunchy, homemade side.

How to Avoid Common Mistakes

Crackers too soft: Bake them longer at a lower temperature (especially if your oven runs hot).
Crackers too hard: Avoid overbaking and pull them from the oven as soon as they’re crisp and lightly golden, as they will firm up further while cooling. Because they are so thin, they can overbake quickly, so keep an eye on them while they bake.
Batter too thin: Use 100% hydration discard or starter (which means fed with equal amount of flour and water) for best results. As a quick fix for thin batter, add some flour a teaspoon at a time until the batter has thick but spreadable consistency.
Batter too thick: Add a little more water (a teaspoon at a time) until your batter reaches spreadable consistency.
Uneven browning: Spread the dough to an even thickness on the lined baking sheet. Either rotate the tray during baking so all crackers bake and color at the same rate OR remove the crackers on the edges of the tray first, then let the ones in the middle bake a little longer.

How to Make Crackers Extra Crispy

This is one of the most common questions with any sourdough crackers recipe, and thankfully, the solution is very simple.

First, spread the dough as thinly as possible on your lined baking sheet. This is key to getting that perfect crisp texture. Then bake until the crackers are fully dried out, even if that means lowering the temperature slightly and extending the bake time.

The best way to check for doneness is to tap a few crackers with your fingernail. They should feel firm and crispy, not soft.

Get these two steps right, and your sourdough crackers will turn out perfectly crisp every time.

Storage Tips

Store completely cooled sourdough crackers in an airtight container at room temperature to keep them crisp. Avoid moisture or humidity which can make them soft.
They’ll stay fresh for about 1 week if stored properly.
You can also freeze baked crackers in an airtight bag or container for up to 2–3 months. Let them come to room temperature after thawing and re-crisp in a low oven if needed.
To re-crisp crackers, pop them into a 300°F (150°C) oven for 5–8 minutes.

Variations

Whole wheat sourdough crackers: Simply use your whole wheat starter or discard and increase the amount of olive oil or butter to 4 tablespoons.
Top with flaky salt before baking if you like a slightly more salty flavor.
Add other herbs like rosemary, thyme, paprika or a pinch of chili flakes.
Cheese crackers: Add 2–3 tablespoons of finely grated parmesan to the batter.
Seeded crackers (sesame, flax, sunflower): Gently press them in with your hand before baking the crackers.

Recipe FAQ

Yes—sourdough crackers are a great way to use up less-active starter since they don’t rely on strong rising.
