I’ll admit it. The process involved with maintaining a healthy sourdough starter and baking hobby can get a little wasteful. All that feeding and dumping, feeding and dumping… But it doesn’t have to be a waste! There are a number of ways you can put that discarded sourdough starter to good use. Most often, we feed ours to the compost or chickens, but another great way to use discarded starter is in other baking recipes – like these delectable, crispy, savory sourdough crackers!
Come learn how to make healthy, whole wheat sourdough crackers with your discarded sourdough starter*. You won’t regret it! These are perfect for holidays, parties, or simply as a healthier cracker snack option for your family. We love to pack ours full of fresh herbs from the garden, but dried herbs can be used instead too. The beautiful thing is, you can use any combination of herbs that are available to you. Have fun making them your own!
Speaking of making them your own, I have to add a disclaimer here: this recipe is sort of based off the popular King Arthur version – but with our personal twists! For example, they call for butter. We opt to make these vegan and use coconut oil instead, which also provides for an extra crispy texture! We also love to use fresh herbs, and a variety of them, rather than dried. The flours used are also different. I hope you love our take on this classic!
*If you need help getting a sourdough starter culture going, check out our simple instructions to make your own – using only three ingredients!
- ½ cup whole wheat flour
- ½ cup unbleached white wheat flour. We used our unbleached bread flour.
- 1 cup unfed, active sourdough starter. Meaning, take the starter at the time you would usually discard it – several hours after feeding, not just-fed. We store our starter in the fridge during the week, and choose not to make this recipe with the very first cold discard. Instead we feed it, let it get active and happy, then use the discard from the next feeding session.
- ½ teaspoon sea salt
- ¼ cup (4 tablespoons) coconut oil
- ¼ cup fresh chopped herbs, or 2 tablespoons dried. We most often use a combination of fresh rosemary, sage, oregano, and thyme from the garden – as shown below.
- Olive oil, for brushing
- Coarse sea salt, for sprinkling on top
- Optional: garlic powder
1) Mix dough
In a large mixing bowl, combine whole wheat flour, white flour, sourdough starter, fresh chopped or dried herbs, salt, and coconut oil. The coconut oil should be slightly softened and easy to work with. If it is hard, you may need to lightly heat it until it just barely starts to melt. If you have only one type of flour available, you can just use whole wheat or white on their own. We personally love the balance of both! Sometimes we like to add 1/8 tsp of our homemade garlic powder to this step too.
Thoroughly mix the dough until it is uniform. I usually start mixing with a fork or spoon, but then finish mixing with my hands. It should not be sticky, especially with the coconut oil.
2) Split, Squish & Cool
Divide the large dough ball into two roughly equal smaller balls. Using your hands, form each ball into a flattened rectangle. We have been vegetarian for a loooong time, but this step definitely reminds me of forming hamburger patties, if that helps… Mine generally end up a little larger than my flattened hand, and maybe about half an inch thick. Repeat for the second ball.
Place each squished dough rectangle on a plate, and cover/wrap with parchment paper. King Arthur calls for plastic wrap, but this is a slightly more sustainable option. The goal is to not allow the dough to dry out. I cut a piece just larger than the dough and tuck it in around the edges.
Refrigerate the dough for at least 30 minutes, up to a couple hours. We tend towards the shorter timeframe – again, to prevent it from drying out.
3) Roll Out
Preheat the oven to 350°F.
Once they’ve had their time to chill, remove the cracker dough from the fridge. Cut a piece of parchment paper to about the size of a cookie sheet. Lightly dust the parchment paper with flour. Carefully unwrap one chunk of flattened dough, place it in the center of the floured parchment paper, and lightly flour the top of the dough. I like to do this on a large cutting board, which makes it easy to transfer onto a cookie sheet.
Using a floured rolling pin, roll out the dough until it is nice and thin. The goal is about 1/16th of an inch thick. The edges will be a little ragged. That is okay. Just work it back and forth and side to side to get it spread as evenly as possible while still maintaining a relatively rectangular shape.
4) Oil, Slice, & Poke
Once the dough is rolled out, lightly brush the surface with olive oil. Don’t drench it! Just enough for a light coating. Then sprinkle some coarse salt over it as well.
Next, cut the dough into rows of square crackers. Anything from 1 to 2 inches is good! The use of a rolling pizza cutter works well for this. We love to use a pastry/pasta cutter to get fun wavy edges.
Finally, poke the top of each cracker with a fork a couple of times.
Repeat Steps 3 and 4 for the second piece of dough.
Slide the parchment paper with cut and poked cracker dough onto a baking sheet. Each batch will need its own cookie sheet. We bake two trays at one time, but if you only have one cookie sheet to work with, have them take turns.
Bake on 350°F for 20 to 25 minutes, until the crackers turn light golden brown. Rotate the cookie sheets halfway through.
When they are done baking, immediately transfer the finished sourdough crackers on to a cooling rack.
The moment we’ve all been waiting for! You’ve probably already sampled a few by now… I always snack on those irregular outer pieces right away. They’re too irresistible, and “not pretty” enough to make it to the plate anyways, right?! Right. Of course.
After fully cooling, store your sourdough crackers in an air-tight container to maintain maximum freshness and crunch. Ours get a tad stale by day 5 or so, but they usually don’t hang around that long!
These herb sourdough crackers are damn good on their own, as a healthier alternative to most other types of crackers or chips. You can enjoy them with cheese and olives, or dunked in hummus and other dips. We had them with soup just last night. So good! Sourdough crackers are our new go-to for holiday and party platters. They are a huge hit, and people are always impressed to learn they’re homemade!
Now get to baking, so you can see for yourself how tasty these are!
