Don't Throw It Away: Creative Ways to Use Sourdough Discard (with Recipes)

If you've been maintaining a sourdough starter, you already know the routine: feed it, watch it bubble, bake with it. And every time you feed it, you're left with that little cup of tangy, slightly funky batter-like stuff. That, friend, is your sourdough discard. And it is not garbage.

What Exactly Is Sourdough Discard?

When you feed your sourdough starter, you pour off (or "discard") a portion before adding fresh flour and water. That removed portion is the discard. It's not dead. It's not ruined. It still has all that wild yeast, all those beneficial bacteria, all that beautiful complex flavor. You just wouldn't want to use it as your sole leavener in a loaf that needs a strong rise. In every other recipe? It's gold.

How to Store Your Discard

• Room temperature: Use within 36–48 hours, then refrigerate or bake with it.
• Refrigerator: Good for up to a week before it gets very sour. Many bakers use it for weeks if their starter is mature — the flavor just deepens.
• Freezer: Freeze in measured portions (1/2 cup is handy) in airtight bags. Lasts up to 3 months. Thaw on the counter before using.

Fresh discard is mild and lightly tangy — perfect for pancakes, waffles, and banana bread. By day 3–4 in the fridge, the tang deepens. By day 5–7, you'll get that unmistakable sourdough zing, ideal for crackers, pizza dough, or flatbread.

Recipe 1: Sourdough Discard Pancakes

Light, fluffy, faintly tangy — they taste like a pancake that went to cooking school.

Ingredients: 1½ cups all-purpose flour, 2 tablespoons sugar, 2½ teaspoons baking powder, ½ teaspoon baking soda, ½ teaspoon salt, ¾ cup sourdough discard (room temperature), 1¼ cups milk, 2 large eggs, 3 tablespoons vegetable oil or melted butter.

Instructions: Whisk together flour, sugar, baking powder, baking soda, and salt. In a separate bowl, whisk together the discard, milk, eggs, and oil until combined. Pour the wet ingredients into the dry and stir just until the flour streaks disappear — a few lumps are fine, do not overmix. Cook on a lightly greased griddle or skillet over medium-low heat, about ¼ cup batter per pancake. Cook until bubbles form and edges look set (about 2–3 minutes), then flip and cook 1–2 minutes more.

Recipe 2: Sourdough Discard Crackers

Three to four ingredients. Twenty minutes. Crispy, salty, tangy crackers that disappear in minutes. Use 5–7-day-old discard for the most flavor.

Ingredients: 1 cup (225g) sourdough discard, 3 tablespoons melted butter (or olive oil), ½ teaspoon salt plus more for topping, 1 teaspoon dried rosemary or everything bagel seasoning (optional).

Instructions: Preheat oven to 325°F. Line a large baking sheet with parchment paper. Mix together the discard, melted butter, salt, and optional herbs. Pour onto the prepared baking sheet and spread as thin as possible — aim for about 1–2mm thick. Sprinkle lightly with flaky salt. Bake 25–35 minutes until golden and the center feels dry and crisp. Let cool completely on the pan — they crisp up more as they cool. Break into rustic pieces.

Recipe 3: Sourdough Discard Pizza Dough

Ingredients: 1 cup (225g) sourdough discard, 2½ cups all-purpose flour, ¾ cup warm water, 1 tablespoon olive oil, 1 teaspoon salt, 1 teaspoon instant yeast (optional).

Instructions: Combine the discard, warm water, olive oil, and yeast. Add flour and salt. Knead for 5–7 minutes until smooth and slightly tacky. Cover and let rise at room temperature for 4–6 hours (or refrigerate overnight for better flavor). Preheat oven to 450°F. Divide dough in half, stretch or roll each half, top as desired, and bake 15–20 minutes until crust is golden.

Recipe 4: Sourdough Discard Waffles

Crispy on the outside, pillowy on the inside. The secret to next-level crispiness? A little cornstarch. These waffles freeze beautifully.

Ingredients: 1 cup sourdough discard, 1 cup milk, 2 large eggs (separated), ¼ cup melted butter, 1 cup all-purpose flour, 2 tablespoons cornstarch, 1 tablespoon sugar, 1 teaspoon baking soda, ½ teaspoon salt.

Instructions: Whisk together the discard, milk, egg yolks, and melted butter. Whisk flour, cornstarch, sugar, baking soda, and salt; add to the wet ingredients and stir until just combined. Beat the egg whites to soft peaks and gently fold into the batter. Cook in a preheated waffle iron until deep golden brown.

Recipe 5: Sourdough Discard Banana Bread

The discard adds just enough tang to cut through the sweetness, making the crumb impossibly tender. Use the most overripe bananas you have.

Ingredients: 3 large very ripe bananas, ½ cup (115g) sourdough discard, 1¾ cups all-purpose flour, ½ cup brown sugar (packed), ¼ cup melted butter, 2 large eggs, 1 teaspoon vanilla extract, 1 teaspoon baking soda, 1 teaspoon baking powder, ½ teaspoon salt, optional: ½ cup chopped walnuts or chocolate chips.

Instructions: Preheat oven to 350°F. Grease a 9x5-inch loaf pan. Whisk together flour, baking soda, baking powder, and salt. In another bowl, mash the bananas and add brown sugar, melted butter, eggs, discard, and vanilla. Add the wet ingredients to the dry and stir until just combined. Pour into the prepared pan and bake 50–60 minutes until a toothpick inserted in the center comes out clean.

Recipe 6: Sourdough Discard Flatbread

Soft, pliable flatbreads in about 45 minutes. Five ingredients. No oven required.

Ingredients: 2 cups all-purpose flour, ½ cup sourdough discard, ½ cup warm water, 2 tablespoons melted butter or olive oil, ¾ teaspoon salt.

Instructions: Whisk flour and salt. Add discard, warm water, and butter. Mix until a shaggy dough forms. Knead 1–2 minutes until smooth. Cover and rest 30 minutes. Divide into 10–12 equal balls. Heat a dry cast-iron skillet over medium-high heat until very hot. Roll each ball into a thin 6–8 inch circle and cook 30–45 seconds per side until puffed and golden in spots.

Recipe 7: Sourdough Discard Crêpes

Thin, delicate, with a whisper of tang. Fill sweet (fresh berries and honey, lemon and powdered sugar) or savory (eggs and cheese, garden greens). Use fresh to mid-aged discard.

Ingredients: ¾ cup sourdough discard, 2 large eggs, 1 cup milk, ½ cup all-purpose flour, 1 tablespoon melted butter, 1 tablespoon sugar (omit for savory), pinch of salt.

Instructions: Whisk together all ingredients until smooth. Let the batter rest 15–30 minutes. Heat a non-stick pan over medium heat and lightly brush with butter. Pour about 3 tablespoons of batter into the center and immediately swirl the pan to spread the batter thin. Cook 60–90 seconds until the edges look dry and lightly golden. Flip and cook 30 seconds more. Note: the first crêpe is almost always a throwaway — the test that seasons the pan.

Zero Waste Is the Homestead Way

Every tablespoon of discard you bake with is a tablespoon you didn't throw away. Across a year of regular starter maintenance, that adds up to pounds of good food — crackers, pancakes, bread, pizza — that came essentially for free from what most people pour down the drain.

This is exactly the mindset we're building at The Hollowpost General. Nothing wasted. Everything used.
