Deliciously tangy and full of flavor, these sourdough biscuits are the perfect way to use up an abundance of sourdough discard!
This past year, banana bread got me back into making sourdough. Well before the quarantine inspired baking challenges, I gradually started mixing and shaping more sourdough loaves after allowing my starter to die several times over years prior.
Banana bread is not the official route into sourdough bread. But it was one of my favorite comfort foods to use and the recipe called for using excess sourdough starter. Basically – sourdough discard. Or the starter that you “discard” before feeding what’s remaining before you start the bread making process.
That sourdough starter makes some of the best banana bread, studded with walnuts and rich in flavor. Discard was what pulled me back in to mixing up more bread – measuring out discarded starter, feeding what was left and then topping the starter with a lid until it started to bubble up hours later.

Sourdough Biscuits with Discard
Over the last few years I’ve grown an attachment to sourdough discard… If you would have asked me early on, I would have told you that discard is just that – discard. Just toss it out and never think twice about it again.
But as time progressed, I realized that discard was indeed one of the best parts of making a sourdough starter. Since then this discard has been used for a variety of favorites:
Sourdough Biscuits
Ingredients
- 1/2 C butter unsalted
- 2 tsp sugar
- 1/2 tsp salt
- 1.5 C all purpose flour
- 1 C sourdough starter discard room temperature
- 1.5 tsp baking powder
- 1/2 tsp baking soda
Instructions
- Preheat oven to 400 degrees F.
- In your mixer, combine the butter, sugar, salt and flour until the mixture resembles coarse crumbs.
- Add in the sourdough starter, baking powder and baking soda and mix just until combined. The dough will come together with just a few crumbs in the bottom of the mixer bowl.
- Turn out the dough onto a well-floured surface.. pat with your hands 1/2" thick (shape doesn't matter). Fold the dough into thirds like you would a letter to create a rough triangle. Pat the dough to 1/2" again, and repeat the folding process. Pat the dough out for the third time to 1" thickness and the fold like a letter again.
- Using a biscuit cutter or floured glass, cut or punch out as many biscuits as you can do. Do not twist as you cut. Transfer to a parchment lined baking sheet 1-2" apart. Gather the scraps, fold into thirds about 1" thick, then cut out more biscuits.
- Bake the biscuits at 400 degrees for 12-15 minutes or until light brown.
