Ingredients needed
The ingredients needed to make rustic sourdough butter crackers are:
- all-purpose flour: Any wheat flour or whole wheat flour will work. I use Einkorn flour in this recipe.
- sourdough starter discard (or active starter)
- butter: non-dairy butter can be used in place of butter.
- salt
Variations
One of the great things about this recipe is that you can make several different flavor variations. Mix one of the following into the dough or sprinkle on top before baking:
- rosemary
- thyme
- basil
- oregano
- herbs de Provence
- grated parmesan cheese
- bagel seasoning
- sesame seeds
Step-by-step instructions
This dough can be mixed and baked the same day, making it a quick and convenient way to use sourdough discard in a pinch.
Step 1: Mix the dough
Preheat your oven to 375ยฐF (190ยฐC).
In a large bowl, add the melted butter, sourdough starter discard, all-purpose flour, and salt. Use a stiff spatula to stir the ingredients together.

The dough should be soft and pliable. It should not stick to your fingers. If the dough seems too sticky, mix in an additional 20 grams of flour.
Step 2: Let the dough rest
Cover the bowl and let the dough to rest for 20-30 minutes for the flour to absorb the liquid.

NOTE: The dough can be fermented for up to 2 days. Wrap the dough in plastic wrap and keep it in the fridge. Let the dough come to room temperature to make it easier to roll out.
Step 3: Roll and cut the dough
Place the dough between two sheets of parchment paper. Use a rolling pin to roll the dough out to a 1/16-inch thickness.
A silicone baking mat works well for baking crackers.

Cut the dough into rectangles using a sharp knife, a bench scraper or a pizza cutter.
Prick each rectangle a few times with a fork. This will keep the crackers from puffing up as they bake.
Step 4: Bake
Slide the parchment paper onto a baking sheet and bake the crackers for 15-17 minutes, checking to make sure they do not overbrown.
The dough on the outside perimeter of the dough will brown more than the center.

Allow the crackers to cool before breaking them apart. They will continue to become more crisp as they cool.
Helpful tips for success
- These crackers do not take long to bake at 375ยฐF (190ยฐC). If your oven tends to run on the hotter side, bake them at 350ยฐF (176ยฐC) for 20-30 minutes to avoid them burning.

Easy to make but mine did not brown. Taste great
HUGE problem with these crackers....I cannot stop eating them.
These were quick to put together and they are absolutely delicious. I usually keep some store bought crackers on hand "just in case" - but since these were ready in about an hour ... I'll be making these instead!
Wow, this is a keeper for sure! This was my first time making any kind of cracker with my discard and I love how they turned out. Buttery, crunchy, savory. I followed the recipe exactly and don't feel the need to add anything.
Favorite cracker recipe. So good.
Delicious and so easy to make!
Great recipe!
2nd time making this I subbed in almond flour for 1/2 of the all purpose flour. They are very crunchy this time and have a lower glycemic index. Donโt know what all almond flour would do but the 1/2 & 1/2 is outstanding
Our new favorite cracker
Great recipe but mine turned out not crispy overnight though I kept them in an air tight container.
I used unbleached bread flour for my starter. Could that be the cause?
Yes Thank you so much for sharing. My sourdough starter is named Madam. She is 2 n 1/2 Months old. And very fragrant. I think they need some extra flavor. Mine turned out crisp n buttery. I placed foil on the edges the last 7 minutes. They still browned someone the ends. I ate maybe 6 or 7 Crackers with some home made Jam n pear butter. I just ate another. Thinking maybe some cheddar cheese, everything bagel seasoning, rosemary and cranberries. So many options. Thanks again, Kathleen. N. E. Wisconsin.
