Can I just bake my sourdough discard?

Technically, you can bake sourdough discard on its own, but don’t expect it to turn into something fluffy or delicious. Without additional leavening like baking powder or soda, it won't rise or form the texture we expect in baked goods. Instead, it's best used in recipes like sourdough discard biscuits , pancakes, crackers, or muffins—where its acidity and moisture bring flavor and softness. So, while you could pop it in the oven, you’ll get far better results when it’s part of a real recipe.

How long to bake sourdough biscuits?

For standard-sized sourdough discard biscuits , bake at 425°F for 12–15 minutes . You’re aiming for golden brown tops and fully cooked centers. Larger biscuits may need up to 18 minutes, but keep an eye on the bottom—if it’s browning too fast, lower the heat slightly. Pro tip: placing biscuits close together on the tray results in softer sides, while spacing them out yields crispier edges.

Is sourdough discard still gut healthy?

Yes, sourdough discard retains some of the fermentation benefits of its active starter. It may contain organic acids , trace probiotics , and a lower phytic acid content , all of which support digestion. While baking kills most live cultures, the discard still contributes to a healthier baked good than many traditional options. That’s part of what makes sourdough discard biscuits not just tasty—but a bit easier on the stomach too.

How do you use old sourdough discard?

Old sourdough discard—if it smells tangy and not spoiled—is ideal for a wide range of recipes. Beyond biscuits, it’s perfect for crackers, waffles, pizza dough, muffins, and quick breads. The longer it's been stored (within reason), the more complex its flavor becomes. To be safe, always check for mold or strange colors. But don’t toss good discard—transform it into something amazing, like buttery sourdough discard biscuits .
