What is Sourdough Discard?

Before we get into the recipe, what even is sourdough discard? Sourdough discard is the part people typically throw away when they are feeding their sourdough starter. This discard is so flavorful that’s why we love to make new recipes with it! In the ingredients list, you will notice baking powder. We have to add baking powder to our sourdough flatbread recipe because, unfortunately, the discard is not strong enough to leaven the sourdough on its own so it needs a helping friend!

Equipment To Make Sourdough Flatbread

  • Wooden or plastic spoon
  • 1 large bowl
  • Plastic wrap
  • Cast iron skillet

How To Make A Sourdough Discard Flatbread

Now let’s make this delicious sourdough flatbread!

First, you will want to combine the flour, salt, and baking powder with your whisk. Once those 3 ingredients are completely combined, it’s time to add the sourdough discard. At the same time you are adding your sourdough discard, you should also add the yogurt and olive oil. Grab that spoon and start mixing!

Once all the ingredients are combined, start to knead your dough. We recommend using the folding method. You can knead this way by pulling one side of the dough over the other. Every time you repeat this step, you should be turning your dough about 90 degrees.

The next step is the easiest, let it rest!  Put your sourdough in a shaded spot and let rest for about 30 minutes. Once you’ve let it rest, it’s time to shape it!

Start to shape your sourdough flatbread by dividing your sourdough into 3 equal pieces. Next, you will roll each of the pieces into disks. Grab your ruler! These disks should be no more than ¼ of an inch thick.

Now, brush only one side of the disk with olive oil. The side that is oiled should go down on your cast iron skillet. Cook on this side for 2-3 minutes and  then flip when it looks bubbly and dry. Once it looks like this, brush the top with more olive oil and flip the sourdough flatbread. Now, let this side cook for another minute then remove from heat. 

Top these sourdough flatbreads with whatever your heart desires! We recommend using your mozzarella and ricotta cheese kit to make a yummy pizza!

Tips and Tricks When Making Sourdough Flatbread

  • Buy a pack of plastic shower caps from a beauty supply store. These work perfectly for covering your dough while it rests. 
  • Add some flavor to that dough! Try adding some minced honey garlic and/or chopped herbs into your sourdough discard flatbread to give it some extra flavor. 
  • Be sure you are cooking on high heat. We know this contradicts most other recipes but this will help make that flatbread nice and crispy. 
  • Cover your sourdough flatbread with a towel to keep them warm while the others cook.
