I’m always looking for simple ways to use up my sourdough discard, and these quick sourdough waffles have become one of my favorite solutions. Instead of letting that extra starter go to waste, I mix it into a fast waffle batter that turns into crispy, golden waffles in just minutes. The flavor is lightly tangy, the texture is fluffy inside with perfectly crisp edges, and it feels like a special breakfast without much effort.
What I love most about this recipe is how convenient it is. There’s no overnight fermentation required and no complicated steps—just a handful of pantry staples and your sourdough discard. Whenever I have discard sitting in the fridge, this is the first recipe I think about. It’s perfect for a weekend breakfast, a quick brunch, or even a cozy breakfast-for-dinner night.
What You Need To Make This Recipe
Sourdough discard:
The star of the recipe. Sourdough discard adds a subtle tangy flavor and helps create tender waffles with great texture. You can use discard that’s been stored in the refrigerator for several days, as long as it still smells fresh and pleasantly sour.
All-purpose flour:
Flour provides structure to the waffles. When combined with the sourdough discard, it helps create a balanced batter that cooks into waffles that are crisp on the outside and fluffy on the inside.
Milk:
Milk thins the batter to the right consistency and adds richness. Whole milk gives the best flavor, but any milk you have on hand—such as 2%, almond milk, or oat milk—can work well.
Eggs:
Eggs help bind the ingredients together and add richness. They also contribute to the light and fluffy texture of the waffles as they cook.
Baking powder:
Since this is a quick recipe without long fermentation, baking powder provides the lift that helps the waffles rise and become airy.
Sugar:
A small amount of sugar adds a touch of sweetness and helps the waffles brown beautifully in the waffle iron.
Butter or oil:
Melted butter or neutral oil adds moisture and flavor while helping create that crispy waffle exterior.
Vanilla extract:
Vanilla enhances the overall flavor and pairs beautifully with the tanginess of sourdough.
Salt:
Salt balances the flavors and keeps the waffles from tasting flat.
Ingredients List
- 1 cup sourdough discard
- 1 cup all-purpose flour
- 1 cup milk
- 1 large egg
- 2 tablespoons sugar
- 1 teaspoon baking powder
- ½ teaspoon salt
- 2 tablespoons melted butter or neutral oil
- 1 teaspoon vanilla extract
How to Make Sourdough Discard Quick Waffles
Step 1: Preheat the Waffle Iron
Start by preheating your waffle iron according to the manufacturer’s instructions. A properly heated waffle iron ensures the waffles cook evenly and develop that signature crisp exterior.
Step 2: Mix the Wet Ingredients
In a large mixing bowl, combine the sourdough discard, milk, egg, melted butter (or oil), and vanilla extract. Whisk everything together until the mixture is smooth and well combined.
Step 3: Add the Dry Ingredients
Add the flour, sugar, baking powder, and salt to the bowl. Gently whisk until the batter is mostly smooth. A few small lumps are fine—overmixing can make the waffles less tender.
Step 4: Let the Batter Rest
Allow the batter to rest for about 5 minutes. This helps the flour hydrate and gives the baking powder a moment to activate, which improves the texture of the waffles.
Step 5: Cook the Waffles
Lightly grease the waffle iron if needed. Pour enough batter into the center to cover most of the grid (the exact amount depends on your waffle maker). Close the lid and cook until the waffles are golden brown and crisp.
Step 6: Serve Warm
Carefully remove the waffles and serve immediately with your favorite toppings such as maple syrup, fresh fruit, yogurt, or butter.
Tips for Making This Recipe
- Use room temperature ingredients for smoother batter and more even cooking.
- Don’t overmix the batter, as this can make the waffles dense instead of fluffy.
- Adjust the thickness by adding a splash of milk if the batter seems too thick.
- Keep waffles warm in the oven at 200°F (95°C) while cooking the remaining batches.
- Make them extra crispy by letting them cook slightly longer in the waffle iron.
- Add mix-ins like chocolate chips, blueberries, or chopped nuts for extra flavor.
- Freeze leftovers by letting them cool completely and storing them in an airtight bag. Reheat in a toaster for best texture.
FAQs
Can I use sourdough starter that hasn’t been discarded yet?
Yes. Active sourdough starter works just as well as discard. The waffles may have slightly more lift and a milder tangy flavor.
How long can sourdough discard stay in the fridge for this recipe?
Discard can usually be used for up to about one week if stored in the refrigerator and it still smells fresh and slightly tangy.
Can I make the batter ahead of time?
It’s best to cook the waffles shortly after mixing the batter. However, you can store the batter in the refrigerator for a few hours if needed.
Can these waffles be made dairy-free?
Yes. Substitute plant-based milk and use oil instead of butter to make a dairy-free version.
How do I store leftover waffles?
Let them cool completely, then store them in the refrigerator for up to 3 days or freeze them for up to 2 months.
How do I reheat frozen waffles?
The easiest way is to toast them in a toaster or toaster oven until hot and crispy again.
