I love finding smart ways to use up sourdough discard, and these waffles have become one of my favorite results. They have a wonderful, subtle tang that sets them apart from standard breakfast waffles, turning what might have been waste into something truly special. I often make a batch on a lazy Sunday morning for my family.
This recipe is incredibly straightforward and comes together in about 20 minutes from start to finish. It delivers consistently crisp-edged, fluffy-centered waffles every time. The process is simple, relying on basic pantry staples to create a memorable breakfast with minimal fuss.
Secrets to Perfectly Crispy Waffles
To achieve that ideal waffle texture—crispy on the outside, tender and airy on the inside—the most important step is ensuring your waffle iron is properly preheated. Hitting the cold batter with high, even heat instantly creates a crust and helps the interior steam, creating a light crumb. Don’t be tempted to open the iron early; wait until the steam slows down significantly. This is your best visual cue that the waffle is cooked through and has developed a beautiful golden-brown exterior. Rushing this step often leads to a soft, pale waffle that can stick and tear.
Why Resting The Batter Matters
While a five-minute rest may seem minor, it serves a crucial purpose in this recipe. This brief pause allows the flour to fully absorb the liquid, which results in a more tender, less doughy texture in the final waffle. It also gives the chemical leaveners, the baking powder and baking soda, a head start. As they begin to react, they create tiny air bubbles in the batter. When this aerated batter hits the hot waffle iron, those bubbles expand, contributing to the light and airy interior that contrasts so well with the crisp crust.
Topping Variations for Every Palate
These sourdough waffles are a fantastic canvas for all kinds of toppings. For a classic approach, you can’t go wrong with a pat of butter and a generous drizzle of pure maple syrup. Fresh berries, like blueberries or sliced strawberries, add a burst of freshness and color, especially with a dollop of whipped cream. If you prefer something richer, try a spoonful of lemon curd or a chocolate-hazelnut spread. For a savory twist, skip the sweet toppings and serve the waffles with a fried egg and a sprinkle of flaky salt, or go all out with crispy fried chicken for a comforting brunch.
Recipe Overview
- Prep Time: 10 minutes
- Cook Time: 10 minutes
- Total Time: 20 minutes
- Servings: 4 waffles
- Difficulty: easy
Ingredients
- 240g sourdough discard (1 cup), room temperature
- 120g all-purpose flour (1 cup)
- 5g baking powder (1 tsp)
- 2g baking soda (1/2 tsp)
- 25g sugar (2 tbsp)
- 3g salt (1/2 tsp)
- 100g large eggs (2)
- 120g milk (1/2 cup)
- 56g butter (1/4 cup), melted
- 5g vanilla extract (1 tsp)
Step-By-Step Instructions
- Preheat Your Waffle Iron
Start by preheating your waffle iron according to the manufacturer’s directions. A properly hot iron is the key to a crisp exterior and prevents the waffles from sticking. This typically takes around 5 minutes.
- Whisk the Dry Ingredients
In a large bowl, whisk together the all-purpose flour, baking powder, baking soda, sugar, and salt. Whisking ensures the leaveners are evenly distributed, which helps the waffles rise uniformly.
- Combine the Wet Ingredients
In a separate medium bowl, lightly beat the two large eggs. Then whisk in the milk, melted butter, and vanilla extract until the mixture is smooth and fully combined.
- Incorporate the Sourdough Discard
Add the room-temperature sourdough discard to your wet ingredients. Whisk until it is fully integrated and the mixture is uniform with no large lumps.
- Combine Wet and Dry Mixtures
Pour the wet ingredients into the bowl with the dry ingredients. Use a spatula to gently fold them together just until no dry streaks of flour remain. A few small lumps are okay; be careful not to overmix the batter.
- Rest the Batter
Let the batter rest at room temperature for 5 minutes. This brief rest allows the flour to hydrate and the baking powder to begin activating, resulting in a more tender, airy waffle.
- Cook the Waffles
Lightly grease your preheated waffle iron if necessary. Pour the recommended amount of batter onto the center of the iron and close the lid. Cook for 3 to 4 minutes, or until the steam subsides and the waffles are a deep golden brown and crisp.
- Serve Immediately
Carefully remove the finished waffle and transfer it to a plate. Serve immediately with your favorite toppings, such as maple syrup, fresh berries, or whipped cream.

Substitutions & Variations
- Chocolate Chip Waffles: Gently fold a handful of chocolate chips into the batter right before cooking for a sweet, melted treat.
- Dairy-Free Option: Use a non-dairy milk like almond or oat milk and a plant-based butter substitute in equal amounts.
- Savory Herb Waffles: Omit the sugar and vanilla, and add 1/2 teaspoon of dried herbs like rosemary or thyme for a savory waffle perfect for brunch.
Make-Ahead, Storage & Reheat
Store leftover waffles in an airtight container in the refrigerator for up to 3 days. For longer storage, freeze them in a single layer on a baking sheet before transferring to a freezer-safe bag for up to 1 month. To reheat and restore crispness, toast them in a toaster or a 350°F / 177°C oven for a few minutes until warmed through.

FAQ
What is the most common reason my waffles are soft instead of crispy?
The most likely cause is steam. Let your iron preheat fully to cook the waffle quickly, and cool the finished waffles on a wire rack, not stacked on a plate.
How can I tell when the waffles are perfectly cooked and ready to remove?
Look for the steam to stop coming out of the waffle iron. This is your best sign that enough moisture has cooked off, leaving you with a crisp, golden waffle.
Why are my sourdough waffles sticking to my non-stick waffle iron?
Sticking usually happens when the iron isn't hot enough. Make sure it's fully preheated before adding batter so the surface sears instantly, creating a crust.
Can I substitute active sourdough starter for the discard in this recipe?
Yes, active starter works well. The waffles will have a slightly milder, less tangy flavor and may rise a bit more, creating a lighter, airier texture.
Does my sourdough discard really need to be at room temperature?
Yes, it's a small step that matters. Room temperature discard is more fluid and mixes smoothly, preventing cold lumps that can create dense spots in your waffles.
How far in advance can I prepare this sourdough waffle batter?
This batter should be used right after its short rest. The baking powder and soda are activated by liquid and will lose their lifting power if left to sit too long.
Is it better to freeze the cooked waffles or the uncooked batter?
Definitely freeze the cooked waffles. The leavening in the batter won't survive freezing, resulting in flat waffles. Cooked, frozen waffles crisp up beautifully.
What happens if I use a lower-fat milk or oil instead of butter?
Using lower-fat milk can make the waffles less rich and tender. Swapping oil for melted butter works, but you'll miss the flavor butter adds to the browning.
Can this sourdough waffle recipe be doubled for a larger crowd?
Yes, you can double all ingredients without any issues. Just be sure to mix in a large enough bowl to combine everything evenly without overworking the batter.
