Key Ingredients & Substitutions
Sourdough Discard: The star of the show! You can use unfed or fed sourdough starter. You can replace it with plain yogurt for a similar tangy flavor, or even buttermilk, but it won’t have the unique texture that sourdough brings.
All-Purpose Flour: This is your go-to, but if you want a healthier option, you can substitute half with whole wheat flour. Just keep in mind that it may make the waffles slightly denser.
Milk: Regular milk works great, but for more flavor, try buttermilk or a non-dairy milk like almond or soy. Adjust the quantity based on the consistency you prefer.
Egg: If you need a vegan version, you can substitute the egg with 1/4 cup of unsweetened applesauce or a flax egg (1 tbsp flaxseed meal mixed with 2.5 tbsp water).
What’s the Best Way to Ensure Crispiness in Waffles?
To achieve that perfect crispy exterior with a fluffy interior, follow these tips:
- Preheat your waffle iron well. A hot iron sears the batter and creates a crispy crust.
- Don’t overmix your batter. Lumps are okay! Overmixing activates the gluten, leading to chewier waffles instead of light and fluffy ones.
- Use enough batter. Filling the waffle iron enough helps create steam, which enhances the fluffiness.
- Let them cool slightly before serving. This helps set the crispy texture without steam turning them soggy.
These little details can make a big difference in your waffle experience. Enjoy your breakfast! 🧇

Sourdough Discard Waffles
Ingredients You’ll Need:
- 1 cup sourdough discard (unfed starter or starter discard)
- 1 large egg
- 1 cup all-purpose flour
- 1 tbsp sugar
- 1 tsp baking powder
- 1/2 tsp baking soda
- 1/4 tsp salt
- 3/4 cup milk (or buttermilk for extra tang)
- 2 tbsp melted butter or vegetable oil
- 1 tsp vanilla extract (optional)
- Cooking spray or extra butter/oil for the waffle iron
How Much Time Will You Need?
Preparation will take about 10 minutes, and cooking each batch of waffles will take about 3-5 minutes, depending on your waffle iron. Overall, you can have a delicious breakfast ready 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. While it’s heating up, lightly grease it with cooking spray or butter to prevent sticking.
2. Mix the Wet Ingredients:
In a large mixing bowl, whisk together the sourdough discard, egg, milk, melted butter (or oil), and vanilla extract (if using) until everything is well combined and smooth.
3. Prepare the Dry Ingredients:
In another bowl, sift together the flour, sugar, baking powder, baking soda, and salt. This will ensure your dry ingredients are well-mixed and help give the waffles a nice rise.
4. Combine Both Mixtures:
Gradually add the dry ingredients into the bowl with the wet ingredients. Stir gently until just combined. Be careful not to overmix; it’s okay if there are a few lumps left in the batter. Overmixing can make your waffles tough!
5. Cook the Waffles:
Pour about 1/2 to 3/4 cup of batter onto your preheated waffle iron, depending on its size. Close the waffle iron and cook until the waffles are golden brown and crisp, which typically takes around 3-5 minutes. Every waffle iron is different, so keep an eye on them!
6. Serve and Enjoy:
Carefully remove the waffles from the iron and serve them immediately. Top with fresh blueberries, strawberries, syrup, or your favorite toppings for an extra delicious breakfast!
7. Repeat:
Continue pouring and cooking the remaining batter, greasing the waffle iron as needed. Enjoy the delicious aroma filling your kitchen!
These waffles are crispy on the outside, fluffy on the inside, and packed with that delightful sourdough flavor. Enjoy your crispy, tender sourdough discard waffles with the lovely tang and hint of sweetness! 🧇
Can I Use Different Types of Sourdough Starter?
Absolutely! You can use either unfed or fed sourdough starter in the recipe. If you don’t have sourdough discard, plain yogurt or buttermilk can be substituted for a similar tangy flavor.
How Do I Store Leftover Waffles?
Leftover waffles can be stored in an airtight container in the fridge for up to 3 days. For longer storage, freeze them in a single layer, then transfer to a freezer bag. To reheat, simply pop them in a toaster or warm them in the oven until crispy.
Can I Make the Batter Ahead of Time?
While it’s best to use the batter fresh for optimal fluffiness, you can prepare the wet and dry ingredients separately beforehand. Just combine them shortly before cooking to ensure your waffles are light and airy!
What Can I Add to the Waffle Batter?
Get creative! You can add chocolate chips, nuts, or spices like cinnamon for extra flavor. Fresh or frozen fruit can also be mixed in for added sweetness. Just be cautious not to add too much additional moisture!
