Start your day with some delicious overnight sourdough waffles. These babies are light and airy on the inside and crispy on the outside. They are the peak of perfection.

This is an essential recipe for anyone that keeps a sourdough starter. It is also a great excuse to make your own sourdough starter if you don’t already have one.
Overnight Sourdough Waffles
Even if you don’t bake bread with your sourdough starter, it is worth the effort to maintain a starter just so you can make incredible recipes with the portion that you need to discard. Recipes like Sourdough Ricotta Pancakes, Buttery Sourdough Biscuits, or these incredible overnight sourdough waffles.
If you think it is too much trouble to maintain a sourdough starter, then consider keeping the starter in the refrigerator. If you store the sourdough starter in the fridge, you will only have to “feed” it once a week. With this in mind, you could take the sourdough starter out of the fridge on the weekend when you plan to make these sourdough waffles.

Light, Crisp, and Airy Waffles
These waffles are absolutely perfect. They are incredibly light and airy on the inside and perfectly crisp and brown on the outside. Just look at the air pockets in the photo above.
They are so light you might be tempted to have a second helping. After all, if they are full of air, then they must be lighter in calories, right? Well, it is a good excuse to justify having a second helping.
These sourdough waffles keep their texture even after they cool as long as you don’t stack them on top of each other. If you stack them and then set them aside to cool then the steam will soften them.
If you want to make a batch of them just before serving, then it is best to place them on a wire cooling rack. However, the best way to store them as your cooking the rest of the batch is to put them in a warm oven that has been pre-heated to 170°F.

Freezing Waffles After They are Cooked
It is not uncommon for us to make a double batch of these overnight sourdough waffles and freeze the waffles that we do not eat. To properly freeze the waffles, you should allow them to cool completely on a wire rack.
Once they are cooled, place them on a baking sheet and put them in the freezer until they are frozen about 1-1/2 to 2 hours. Next, place the frozen waffles in a freezer safe plastic bag. You can store frozen waffles for 3 months. Pull them out of the freezer for a fast and easy breakfast.

I love waffles but would like to know if I can use almond milk for these? I am dairy intolerant and this would be too much regular milk for me. I would also like to use Ghee in place of the butter. What do you think?

Yes, almond milk or oat milk will work just fine. You can replace the butter with Ghee or olive oil. Thanks for your question. We have lactose-intolerant family members as well and understand the struggle.

I have made these several times and always with great results. I got a request this morning for them and had not prepared the batter last night.. sad. . So I prepared as usual but added a half teaspoon of baking powder. Voila! Turned out super! Glad to have a Backup plan for when timing just doesn’t work out. Thanks!
