Overnight Sourdough Waffles

June 5, 2022

Two Overnight Sourdough Waffles stacked on a plate with a hand holding a fork poked into the waffles, with a mini glass pitcher of syrup, a butter dish and a vase with flowers in the background.

With school days all wrapped up for the semester, we are devoting our newly found free time in the mornings to sleeping in a little later followed by long, slow, lazy breakfasts – like these Overnight Sourdough Waffles. Although they require just a bit of forethought (the sponge is made the night before), they could not be easier. Combine that with the fact that everyone who has tried them declares them the BEST waffle they’ve ever had, we’ve got a keeper!

What makes these Overnight Sourdough Waffles so amazing? I believe it’s the distinction of textures – the outside is buttery and crisp, while the inside is tender, light, airy, spongy… think of the inside of a really good churro! I also love the slight tang of the sourdough flavor along with the sweetness of maple syrup. I’ve been making them every morning for the last week just to make sure the recipe is just right, and we’re still eating them up as if we’ve never beheld such a waffle before.

This recipe makes four large Belgian style waffles. It would easily double, and I think you’d be glad you did if your family wakes up hungry like mine. To make the sponge the night before, just add sourdough starter to a bowl along with plain Greek yogurt, milk, sugar, and flour. Mix this together and then cover it and allow it to sit overnight.

In the morning, when you are ready to make the waffles, add melted butter, an egg, vanilla extract, salt, and baking soda. Whisk that together and watch as it puffs up in the bowl. Preheat your waffle iron, and then scoop about 1 cup of batter onto the waffle iron.

I think every waffle iron varies slightly, but aim to cook the waffles for 2-3 minutes or until the outside is a deep golden brown.

Enjoy immediately, and to the fullest, with all the butter and maple syrup you desire. Bacon is a good idea. Breakfast is served!

Description

These Overnight Sourdough Waffles are by far the BEST we’ve ever had! The outside is crisp and buttery, while the inside is light and tender.


Ingredients

Scale

For the Overnight Sponge

  • 100 grams active sourdough starter
  • 120 grams (1/2 cup) milk
  • 140 grams (1/2 cup) plain Greek yogurt
  • 12 grams (1 tablespoon) granulated sugar
  • 120 grams (1 cup) all-purpose flour

For the Waffle Batter

  • 55 grams (1/4 cup) butter, melted and cooled
  • 1 egg
  • 4 grams (1 teaspoon) vanilla extract
  • 3 grams (1/2 teaspoon) Kosher salt
  • 5 grams (1 teaspoon) baking soda

Instructions

For the Overnight Sponge

  1. In a large bowl, whisk together active* starter, milk, yogurt, sugar, and flour until smooth.  Cover and leave at room temperature overnight.

For the Waffle Batter

  1. To the overnight sponge, add melted butter, egg, and vanilla extract.  Whisk together until incorporated.
  2. Sprinkle salt and baking soda evenly over the top of the batter.  Whisk all together.
  3. Preheat the waffle iron while the waffle batter sits.  It should puff slightly in the bowl.
  4. Pour 1 cup of batter onto the waffle iron and cook 2-3 minutes.  Repeat with remaining batter.

Notes

*I have used both active and inactive starter with good results.  I think as long as your starter has been fed within that last 8-12 hours, it is fine to use.

    These were very good! Crispy on outside, fluffy on inside. Only made 3 round waffles so I’ll double or triple the ingredients next time!!

    These were great. 5-year-old said they were the best waffles he’d ever had. I used almond milk and inactive starter, though I did throw it in the oven on the proofing setting for 30 mins in the morning. This was just a little shy of what we wanted to feed our family of 4, so I’ll double it next time and freeze the extras. My new go-to for waffles!

    I love this recipe but I always forget if it’s salted butter or unsalted butter that should be added. I can never remember what I did last time.🫥

    Just tried this recipe. Easy to assemble. My brother said it was a success. Light and fluffy. And he liked the crunch. Soaks up copious amounts of syrup.Thank you!

    My husband and I both agree that these were the best waffles we’ve ever had. They turned out perfectly crispy on the outside, light and fluffy on the inside and had a nice buttery flavor. We’ll definite be making these again soon. Thank you for an awesome recipe!
