These Sourdough Discard Waffles are a fun way to use up extra sourdough starter! They’re fluffy, crispy, and have a yummy tangy flavor that makes breakfast exciting.
Honestly, I love how quick they are to whip up! Just mix the ingredients, pour them into the waffle maker, and you’re ready to enjoy a tasty treat. Perfect for breakfast or brunch! 🧇✨
Key Ingredients & Substitutions
Sourdough Discard: This is the star ingredient! Using unfed sourdough starter gives your waffles a slight tanginess. If you don’t have sourdough, you can use plain yogurt or buttermilk for a similar flavor.
Flour: All-purpose flour works great here, but you could try whole wheat flour for a nuttier taste. Just remember that whole wheat will make the waffles a bit denser.
Milk: I often use buttermilk because it adds extra flavor. If you’re out of buttermilk, mix regular milk with a splash of vinegar and let it sit for a few minutes—voila!
Granulated Sugar: This adds sweetness. If you want less refined sugar, consider using honey or maple syrup instead!
Vanilla Extract: A must for flavor! If you don’t have it, any flavored extract can work, such as almond extract for a different twist.
How Do I Get Perfectly Crispy Waffles?
The key to crispy waffles is the batter, and how you cook them. Here’s how to achieve that crunchy exterior.
- Make sure to preheat your waffle iron thoroughly. A hot iron creates that lovely crispiness.
- Grease the iron well with melted butter. It adds flavor and helps prevent sticking.
- Allow the baking soda to react. Gently folding it in causes bubbles to form, which will give your waffles a light texture.
- Don’t lift the lid too early! Wait until they’re golden. If you peek too soon, they could get soggy.

Ingredients You’ll Need:
For the Waffles:
- 1 cup sourdough discard (unfed starter)
- 1 cup all-purpose flour
- 1 cup milk (or buttermilk for extra tang)
- 2 tablespoons granulated sugar
- 1 large egg
- 3 tablespoons melted butter (plus extra for greasing)
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 teaspoon vanilla extract
For the Toppings:
- Fresh blueberries

How Much Time Will You Need?
This recipe will take about 15 minutes to prepare and another 10-15 minutes to cook the waffles, depending on your waffle iron. So, you can enjoy delicious waffles in about 30 minutes!
Step-by-Step Instructions:
1. Preheat the Waffle Iron:
Start by preheating your waffle iron according to the manufacturer’s instructions. Once it’s hot, lightly grease it with melted butter to keep the waffles from sticking.
2. Mix the Batter:
In a large mixing bowl, combine the sourdough discard, flour, milk, sugar, egg, melted butter, salt, and vanilla extract. Stir everything together until the mixture is smooth. It should be creamy and lump-free!
3. Add the Baking Soda:
Now it’s time to sprinkle the baking soda over the batter. Gently fold it in with a spatula. You’ll notice the batter start to bubble a little—that’s the baking soda reacting with the acidity in the sourdough, which makes your waffles fluffy!
4. Let the Batter Rest:
Allow the batter to rest for about 5-10 minutes while your waffle iron finishes heating up. This helps the ingredients blend nicely and enhances the texture.
5. Cook the Waffles:
Pour the appropriate amount of batter onto your preheated waffle iron (usually about 1/2 to 3/4 cup, depending on your iron’s size). Cook according to your waffle iron’s instructions, typically until they are golden brown and crispy on the outside.
6. Serve the Waffles:
Once cooked, carefully transfer the waffles to a plate. Top them with fresh blueberries, banana slices, a dollop of whipped cream or a scoop of vanilla ice cream, and drizzle generously with maple syrup for that perfect finish!
7. Enjoy!
Serve immediately while they’re warm and crispy. Enjoy every delightful bite of your homemade sourdough discard waffles!
Can I Use Active Sourdough Starter Instead of Discard?
Yes, you can use an active sourdough starter! Just make sure to adjust the amount slightly. Since it’s already fed, you may need to reduce the liquid in the recipe by a couple of tablespoons to maintain the right consistency.
Can I Make These Waffles Gluten-Free?
Absolutely! Substitute the all-purpose flour with a 1:1 gluten-free flour blend. Check that the blend contains xanthan gum for the best texture.
How Should I Store Leftover Waffles?
Leftover waffles can be stored in an airtight container in the refrigerator for up to 3 days. For longer storage, place them in a zip-top bag and freeze for up to 3 months. To reheat, toast them in a toaster or oven until warmed and crispy!
Can I Add Other Mix-Ins to the Batter?
Definitely! Feel free to add in chocolate chips, nuts, or even spices like cinnamon to customize the flavor of your waffles. Just fold in the mix-ins at the same time you add the baking soda.
