These overnight sourdough waffles are as easy as tossing together a batter using sourdough starter in the evening, letting the magic happen overnight, and sitting down to a spectacular breakfast in the morning.
*What is Kefir?
In the simplest terms, kefir is a fermented milk drink similar to a thin yogurt or buttermilk. Kefir grains are added to milk and within 24 hours (depending on the temperature in your kitchen), you’ll have a fermented and cultured probiotic liquid that can be used in many of the ways you’d use buttermilk or yogurt.

Special Equipment: Waffle Iron
The night before you plan to make waffles, in a large bowl, gently combine the flours, sugar, kefir, and sourdough starter. Cover the bowl tightly with plastic wrap and allow to sit at room temperature overnight.
In the morning, the batter should be visibly bubbly.
In a small saucepan over low heat, melt the butter and then let cool until nearly room temperature.
In a small bowl, whisk together the eggs, salt, baking soda, and cooled melted butter. Stir this into the flour mixture, mixing until just combined.
Coat the waffle iron with nonstick spray or melted butter and heat until very hot. Following your machine’s instructions, pour the batter into the waffle iron, spreading it to cover the surface and being careful not to overfill. Cook the waffles until golden brown and cooked through, 3 to 4 minutes.
Serve immediately with additional butter and your favorite toppings.
Recipe Testers' Reviews
We are recently into making milk kefir at home and I have been baking sourdough and maintained starters for years. And we love making sourdough waffles. So, the title of this recipe was a no-brainer to test out and it delivered wonderfully.
The tartness is more pronounced than when I usually make my regular recipe with buttermilk and I loved the addition of buckwheat flour to the batter. It stands up great to the assertive flavors of sourdough starter and kefir.
I made half a recipe a couple days later as well (I had a good bit of my starter left anyways) and used teff flour instead of buckwheat this time. Also awesome and mildly sweeter than the earthy buckwheat. Both are delicious and this simple recipe is an enthusiastic TC for me.
These waffles are nice. They are not at all laborious even though the overnight ferment means planning ahead. They have a pleasantly light texture, a mild tang from the sourdough starter and kefir, and they aren't at all sweet which appeals to me because it allows them to go in either a savory or sweet direction. These are a good vehicle for whatever you want to serve with them.
In the morning, the batter had almost doubled and was beautifully jiggly and bubbly. We served them with macerated strawberries, blackberries and peaches, along with blackberry bourbon maple syrup, and freshly whipped cream mixed with sour cream, brown sugar and vanilla. I mean what could possibly be bad about that?!
All that being said, buckwheat flour is something that I almost never have on-hand, and I don't think I’d seek it out just for this recipe. There are plenty of great waffle recipes that use up starter, but that don't require a rarely used ingredient like buckwheat. But hey, if you've got a bag of buckwheat flour to burn through this is certainly a nice recipe to make use of it.
