8 Sourdough Discard Recipes That Help You Waste Less
That jar of sourdough discard in your fridge might hide your next favorite recipe. Instead of pouring leftover starter into the trash, you could turn it into crispy crackers, fluffy pancakes, homemade pizza, or even chocolate chip cookies. And with the U.S. Department of Agriculture estimating that 30% to 40% of the nation’s food supply goes to waste, finding creative uses for ingredients already in your kitchen makes plenty of sense.
Sourdough discard is simply the portion of starter removed during regular feedings, and it can add a pleasantly tangy flavor to all kinds of baked goods. The possibilities are expanding beyond traditional bread, with King Arthur Baking featuring 15 creative discard recipes in a 2024 roundup.
Here are eight worth trying, whether you’re looking for a quick snack, a satisfying breakfast, or an excuse to turn on the oven.
Classic Sourdough Pancakes
Classic sourdough pancakes are a delicious way to give leftover starter a second life, especially when you want something different from your usual breakfast routine. King Arthur Baking’s recipe uses 1 cup (227 grams) of discard mixed with buttermilk, flour, and sugar to create an overnight sponge that develops flavor for approximately 12 hours.
The following morning, eggs, butter or oil, baking soda, and salt complete the batter before it reaches a hot griddle. The recipe makes about 24 medium pancakes, so it’s a practical choice for a family breakfast, though the overnight prep means you’ll need to plan ahead rather than mix when everyone is already hungry.
Crispy Sourdough Discard Crackers
Sourdough discard crackers prove that something wonderfully crunchy can begin with an ingredient you nearly threw away. King Arthur Baking’s version combines about 1 cup of discard with melted butter, salt, and your preferred seasonings or seeds to make a simple batter that doesn’t require kneading or a rolling pin.
Spread the mixture thinly on a parchment-lined baking sheet, bake briefly, score into squares, then bake until the crackers are crisp. Recipe developer Molly Marzalek-Kelly’s version yields about five dozen small crackers, making it especially appealing when you want a homemade snack without an elaborate ingredient list.
Buttery Sourdough Biscuits
Buttery sourdough biscuits deserve a spot on your baking list if you enjoy golden, tender biscuits with a little extra character. King Arthur Baking’s recipe uses just five main ingredients: flour, baking powder, salt, cold butter, and 1 cup (227 grams) of sourdough discard.
The dough is gently mixed, patted into a thick round, cut into biscuits, and baked at 425°F until beautifully golden. Better still, the recipe yields six to seven large biscuits in about 30 minutes, making it one of the most convenient ways to turn leftover starter into something worth serving with breakfast or dinner.
Homemade Sourdough Pizza Crust
Sourdough discard pizza crust might change how you approach homemade pizza night, particularly if you enjoy experimenting with different dough flavors. King Arthur Baking’s version combines 1 cup (227 grams) of unfed starter with flour, water, and other ingredients, including instant yeast, to create a chewy crust with a distinctive sourdough character.
The recipe makes one 14-inch round pizza, a large rectangular thick-crust pizza, or two 12-inch thin-crust pizzas, depending on how you shape the dough. While total prep and rise time approaches five hours, hands-on prep takes only about 10 minutes, making this a better choice for a planned pizza night than a spontaneous dinner.

Quick Sourdough Crumpets
Sourdough crumpets are an excellent option when you want to use a generous amount of discard without committing to a lengthy baking project. These small, griddled breakfast treats develop characteristic holes, making them especially inviting with butter, jam, or other favorite toppings.
King Arthur Baking’s recipe calls for 1 cup (227 grams) of discard, plus sugar, salt, and baking soda, and yields four to five crumpets in about 11 minutes. The recipe is impressively quick, though traditional crumpets use rings; if you don’t have them, King Arthur suggests making free-form pikelets instead, another simple way to enjoy the same mixture.
Sourdough Banana Bread
Sourdough banana bread is what happens when two ingredients waiting around your kitchen finally get the attention they deserve. Ripe bananas bring familiar sweetness, while leftover sourdough starter adds a subtle tang that adds another dimension to this popular homemade loaf.
King Arthur Baking’s recipe calls for about 1¾ cups of mashed banana and ½ cup (113 grams) of discard, plus honey, brown sugar, butter, eggs, flour, and spices. The result is one loaf with about 12 generous servings, and although baking takes more than an hour, it’s especially useful when you’re trying to make something worthwhile from both excess starter and ripening bananas.
Sourdough Blueberry Muffins
Sourdough blueberry muffins offer another clever way to use leftover starter while preparing something familiar for breakfast or an afternoon coffee break. King Arthur Baking’s recipe combines 1 cup (227 grams) of sourdough discard with blueberries, cornmeal, flour, cinnamon, and other baking ingredients to create muffins with a slightly tangy flavor and a gentle cornmeal crunch.
The recipe yields 12 muffins and takes approximately 35 minutes from start to finish, including 14 to 18 minutes in the oven. A practical detail: frozen blueberries can go straight into the batter without thawing, so this recipe works even when fresh berries aren’t sitting on your kitchen counter.
Sourdough Chocolate Chip Cookies
Sourdough chocolate chip cookies might be the most surprising reason to keep your leftover starter around, especially if cookies are already a regular part of your baking routine. King Arthur Baking features a recipe adapted from pastry chef Caroline Schiff’s The Sweet Side of Sourdough that combines sourdough discard with browned butter, brown sugar, and chopped chocolate for cookies with crisp edges and chewy centers.
Schiff describes her ideal chocolate finish as having “plenty of puddles of chocolate with a salty pop to finish,” a combination that makes these cookies sound especially tempting. The recipe uses 135 grams of discard and yields about 16 to 18 cookies, but the dough needs an extended rest, so this is a treat worth planning rather than rushing.
Next time you feed your sourdough starter, remember that the portion you remove doesn’t automatically belong in the trash: it could be the start of something delicious.
