🧇 My Sourdough Waffle Story
"Crispy on the outside, fluffy on the inside – the best way to use up that sourdough discard!" 🧇✨
If you maintain a sourdough starter, you know the drill – feed, discard, repeat. But what if that "discard" could become the best waffles you've ever made?
That's exactly what I discovered. Sourdough discard waffles are crispy on the outside, fluffy on the inside, with that signature tangy flavor that makes sourdough so special. They're quick to make, use up your discard, and turn a simple breakfast into something extraordinary.
💬 The secret: The acidity in sourdough discard reacts with baking soda to create the lightest, fluffiest waffles you'll ever eat – and that tangy flavor is absolutely irresistible!
📦 Ingredients
For 6-8 Waffles:
- 🥣 1 cup sourdough discard (unfed, straight from the fridge is fine)
- 🌾 1 cup all-purpose flour
- 🥛 1 cup milk (or buttermilk for extra tang)
- 🥚 2 large eggs
- 🧈 ¼ cup melted butter (or vegetable oil)
- 🍬 2 tablespoons sugar
- 🧂 ½ teaspoon salt
- 💨 1 teaspoon baking soda
- 💨 1 teaspoon baking powder
💡 Note: The baking soda reacts with the acid in the sourdough discard – this is what gives the waffles their incredible lift and fluffy texture.
🔧 Essential Equipment
- 🧇 Waffle iron – Belgian or classic
- 🍲 Large mixing bowl
- 🥄 Whisk
- 🥄 Ladle or measuring cup – for pouring batter
📝 Step-by-Step Instructions
Step 1 – Preheat Your Waffle Iron
- Preheat your waffle iron according to the manufacturer's instructions.
- Lightly grease with cooking spray or melted butter.
Step 2 – Mix the Batter
- In a large bowl, whisk together the sourdough discard, milk, eggs, and melted butter.
- Add the flour, sugar, salt, baking powder, and baking soda.
- Whisk until just combined – do not overmix. A few lumps are fine.
Step 3 – Cook the Waffles
- Pour the batter onto the hot waffle iron (amount depends on your iron).
- Close the lid and cook until golden brown and crispy, about 3-5 minutes.
- Remove carefully and serve immediately.
Step 4 – Keep Warm
- If making multiple batches, keep cooked waffles warm in a 200°F oven on a wire rack (this keeps them crispy).
🔥 Pro Tips for Perfect Waffles
- 🔥 Preheat thoroughly: A fully heated waffle iron is essential for crispy waffles.
- 🥄 Don't overmix: Overmixing develops gluten and makes waffles tough. Mix just until combined.
- 🧇 Let it rest: For even fluffier waffles, let the batter rest for 5-10 minutes before cooking.
- 🧈 Use melted butter: Butter adds flavor and creates a crispy exterior.
- 🔄 Keep them warm: Place cooked waffles on a wire rack in a low oven to stay crispy.
🧊 Storing & Reheating
Refrigerator (Up to 3 Days):
- Let waffles cool completely.
- Store in an airtight container or ziplock bag in the refrigerator.
- Reheat: Toaster or toaster oven for crispy results; microwave for soft results.
Freezer (Up to 3 Months):
- Cool completely. Place on a baking sheet and freeze until solid.
- Transfer to a freezer bag or airtight container.
- Reheat: Toast directly from frozen – they'll come out perfectly crispy!

❓ Frequently Asked Questions
❓ Can I use sourdough discard straight from the fridge?
Yes – it works perfectly straight from the fridge. No need to bring it to room temperature.
❓ Why do I need both baking soda and baking powder?
Baking soda reacts with the acid in the discard for immediate lift. Baking powder provides additional rise.
❓ Can I make these dairy-free?
Yes – use oat milk or almond milk and a dairy-free butter alternative. The waffles will still be delicious.
❓ Why are my waffles not crispy?
Your waffle iron might not be hot enough, or you might be opening it too soon. Let it preheat fully and cook until golden brown.
❓ Can I freeze these waffles?
Absolutely! Freeze in a single layer, then transfer to a bag. Toast directly from frozen for perfect results.
❓ How do I reheat waffles?
For crispy results, use a toaster or toaster oven. For soft results, use a microwave for 15-20 seconds.
❓ Can I use whole wheat flour?
Yes – use a 50/50 mix of white and whole wheat for a heartier waffle.
❓ Why is my batter lumpy?
That's normal! Lumpy batter is fine – overmixing is the enemy. A few lumps create a tender texture.
❓ Can I add mix-ins to the batter?
Yes – fold in chocolate chips, blueberries, or chopped nuts after mixing.
❓ How long does the batter last?
Use immediately for best results. The baking soda will start reacting right away.
