What is Sourdough Discard?

Sourdough discard is the portion of sourdough starter you remove before feeding it. When you maintain an active sourdough starter, you typically discard some of it so the remaining starter can stay healthy and strong.

Even though it’s called “discard,” it’s still full of flavor and beneficial fermented elements. While it won’t give you the same rise as active starter, sourdough discard is perfect for recipes like sourdough discard waffles, muffins, pancakes, cookies and quick breads.

You can use sourdough discard straight from the fridge or at room temperature — just give it a quick stir before adding it to your batter.

Ingredients You’ll Need

These sourdough discard waffles are made with simple pantry staples — nothing complicated.

A flat lay of the ingredients needed for the recipe

All-purpose flour – Gives structure and keeps the waffles light and fluffy.
Sugar – Just enough to help them caramelize and crisp.

Baking soda – Reacts with the sourdough discard for extra rise.
Salt – Balances the flavor and enhances the tang.
Sourdough discard – Adds depth of flavor and tender texture. (Unfed discard works perfectly.)

How to Make Sourdough Discard Waffles

Please see the recipe card at the bottom of this post for the full recipe details.

1. Preheat your waffle iron.
Let it fully heat so you get crispy edges from the start. Lightly grease if needed.

2. Mix the dry ingredients.
In a medium bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.

4. Combine gently.
Pour the wet ingredients into the dry ingredients and stir just until combined. Don’t overmix — a few small lumps are perfectly fine.

5. Let the batter rest.
Allow the batter to sit for 5–10 minutes. This helps the flour hydrate and creates fluffier waffles.

6. Cook until golden and crisp.
Pour the batter into your preheated waffle iron and cook according to your machine’s instructions, usually 3–5 minutes, until golden brown.

7. Cool briefly on a wire rack.
Place cooked waffles on a wire rack instead of stacking them. This keeps them crispy instead of soggy.

Recipe Tips

Preheat your waffle iron fully. A hot iron is key for crispy, golden edges.

Use melted butter for better browning. It creates more flavor and crisp texture than oil.

Don’t overmix the batter. Stir just until combined to keep the waffles light and fluffy.

Let the batter rest 5–10 minutes. This helps hydrate the flour and improves texture.

Cool waffles on a wire rack. This is important — stacking traps steam and makes them soggy.

Replace ¼–½ cup flour with blended cottage cheese for a natural protein boost.

How to Store and Reheat Sourdough Discard Waffles

These sourdough discard waffles store beautifully, which makes them perfect for meal prep and busy mornings.

How to Store Waffles in the Refrigerator

Let the waffles cool completely.
Store them in an airtight container.
Keep in the refrigerator for up to 4 days.

Cooling them fully before storing prevents excess moisture and sogginess.

How to Freeze Sourdough Discard Waffles

Allow waffles to cool completely.
Place them in a single layer on a baking sheet and freeze until solid.
Transfer to a freezer-safe bag or container.

They will keep well in the freezer for up to 2–3 months.

Freezing them flat first prevents sticking and makes it easy to grab one at a time.

How to Reheat Waffles (So They Stay Crispy)

For best results, reheat waffles in the toaster straight from the fridge or freezer. This brings back their crispy edges and fluffy center.

Avoid the microwave if possible — it makes waffles soft instead of crisp.

Serving Suggestions

These sourdough discard waffles are incredibly versatile and can be served in so many simple ways:

Butter and real maple syrup for a classic, cozy breakfast.
Fresh berries and whipped cream for something light and naturally sweet.
Scrambled eggs and sausage for a balanced, high-protein meal.
Bananas with peanut butter or warm berry compote for a comforting weekend option.
Fried eggs, bacon, and shredded cheddar (reduce sugar slightly in the batter) for a savory twist.
