Sourdough waffles are the most airy and fluffy waffles but still super crisp on the outside. Make the batter for the waffles in the evening and the next morning you’ll get to enjoy such a treat.
Sourdough waffles are my absolute favorite way to use my sourdough starter. Besides baking all sorts of sourdough breads, I have experimented the most with waffle recipes.
Even though I love Belgian waffles too, sourdough waffles are far superior. As the batter stands overnight, it becomes so bubbly and active. That translates to lots of bubbles on the inside as the waffles cook. The sourdough also gives the waffles are mildly tart flavor. It’s the perfect recipe to put your sourdough discard to good use.
I always make a big batch because waffles reheat really well and can even be frozen, which is so convenient for easy breakfasts in the future.

Ingredients:
- sourdough starter
- this is the most important ingredient in this recipe, of course. You can’t make sourdough waffles without a sourdough starter. If you have a friend who uses sourdough, get some from them. A more mature starter is the best, but you can also make your own sourdough starter. These are the tutorials I used several years ago when I first started working with sourdough.

- granulated sugar
- all purpose flour
- milk + sour cream
- Instead of using buttermilk, I use whole milk and sour cream. The waffles turn out much more crisp and are not as tart as when using buttermilk.
- eggs
- oil or melted butter
- I use avocado oil, but you can use any other mild oil, coconut oil or even melted butter.
- salt
- baking soda
How To Make the Overnight Sponge
The overnight sponge is really easy to make – all you do is mix all the ingredients in a bowl and let it hang out overnight at room temperature. Of course, that means you have to plan ahead, but it’s really a very simple process. It makes all the difference in the texture of your waffles. Without giving the sponge time to get bubbly, the waffles will be much more dense and heavy. All the air bubbles that are created overnight will make the waffles incredibly airy and tender.
- Prepare the overnight sponge. Mix together the milk and sour cream, then add the sourdough starter and sugar. Then add the flour and mix until evenly combined. The batter will be thick and smooth. Cover with plastic wrap or a towel and leave at room temperature for about 12 hours or overnight.
- In the morning, the batter will have grown and become bubbly and airy.
How To Make Sourdough Waffles
- Add the eggs and oil to the overnight sponge. In a medium bowl, mix the eggs with the oil, then add to the batter.
- Lastly, add the salt and baking soda. Mix to combine.
- Heat up the waffle iron and brush with oil on both sides.
- Pour the batter into the waffle iron, gently spreading it out. Cook until golden brown and cooked through.
- Serve the waffles warm, with your favorite toppings: melted butter, maple syrup, honey, fresh fruit and/or berries, powdered sugar, etc.
Helpful Tips and Frequently Asked Questions:
Technically yes, but you won’t have the same results. It can be really frustrating if you want to have waffles for breakfast and then you read through the recipe and discover that you need to wait for 12 hours – Ugh!
Sourdough really excels when it’s given a time to ferment and create lots of air bubbles. This is what will give the waffles just an airy and light texture. The time will also give the waffles a pleasant tart flavor from the sourdough.
Even though you can still make the batter, make the “sponge” and then just add the remaining ingredients right away and make your waffles, they will be much more dense and not as delicious.
If you want waffles right away, I recommend you use my Belgian Waffle recipe – no waiting or sourdough starter required.
Make sure to brush the waffle iron grates with oil on both sides EACH time to pour in more waffle batter. This will help to make the waffles as golden and crisp as possible, and help them easily come out of the iron too.
After the waffles are cooked, don’t stack them on top of each other. The warm steam from the other waffles will make your waffles get soft. Instead, serve them right away, or place them in a single layer on a baking sheet with a rack on top. (You can keep them warm while cooking the rest of the waffles in an oven preheated to 200 degrees F.)
Most recipes use buttermilk but I chose to use sour cream and milk instead. Sourdough waffles with buttermilk are much less crunchy. They also have a much more distinct tart flavor.
The waffles with milk and sour cream are very crisp and crunchy on the outside but still very tender and airy on the inside.
Absolutely! Waffles freeze really well. Place them in a freezer ziptop bag or an airtight container. I like to place some parchment paper in between the waffles so they don’t stick together. Freeze for 1-3 months.
Then, simply thaw and reheat the waffles in your toaster, air fryer or oven until warmed through.

- Add the salt and baking soda. Mix to combine.
- Heat the waffle iron and use additional oil to brush the grates on both sides.

- Cook until golden brown and cooked through.
- Serve the waffles right away with your favorite toppings: melted butter, maple syrup, honey, fresh fruit and/or berries, etc. Store leftover waffles in the refrigerator for 3-5 days or freeze for 1-3 month.
Notes
While cooking the waffles, I like to warm the oven to 200 degrees Fahrenheit and place the waffles on a baking sheet topped with a rack to keep them warm while I am cooking the next set of waffles.
