We’ll send it straight to your inbox, along with weekly dinner inspiration!

If you’re tired of pouring precious sourdough discard down the drain, this sourdough discard waffles recipe is about to become your new favourite breakfast ritual. These waffles deliver that signature tangy sourdough flavour, ultra-crispy edges, and a light, airy interior, all while using up to 200g of discard in one go.

Whether you want breakfast ready in under 20 minutes or prefer a deeper, more developed flavour, this versatile recipe has you covered. With the right technique, you’ll get golden waffles that rival your favourite café. Let’s turn that jar of discard into something worth waking up for.

Sourdough Discard Is Anything But Waste

This is liquid gold for flavor. The natural acids and wild yeasts tenderise the crumb and create a complex tang that plain baking-powder waffles simply can’t match. These waffles freeze beautifully and reheat in the toaster like shop-bought ones, only better.

The average home sourdough baker discards hundreds of grams of starter weekly. This recipe helps you slash food waste while gaining probiotic-like benefits from the fermented flour!

What Makes These Waffles So Special

These sourdough discard waffles make excellent use of what would otherwise go to waste, allowing you to use a generous amount of discard in one batch while getting real value out of it. The texture strikes that ideal balance, with crispy, golden edges and a soft, airy interior that feels light rather than heavy.

Another reason this recipe stands out is its flexibility. You can prepare the batter and cook the waffles the same day for a quick breakfast, or let it rest overnight to develop a deeper, more complex flavour. It also adapts easily to whatever you’re in the mood for, whether that’s sweet toppings like fruit and syrup or a more savory approach.

On top of that, these waffles are practical for everyday life. They store well, freeze beautifully, and reheat in a way that brings back their crisp texture, making them a reliable option for meal prep or busy mornings.

PREP

10–15 mins (plus optional overnight)

COOK

20–30 mins

TOTAL

20 mins

SERVINGS

8–10 waffles

INGREDIENTS

200 g sourdough discard (100% hydration, room temperature, fresh or fridge up to 2 weeks old)
2 large eggs (room temperature)
200–380 g buttermilk (or whole milk + 2 tbsp lemon juice/vinegar for homemade)
60 g unsalted butter, melted and cooled (French butter for extra richness)
170–200 g all-purpose flour (or half bleached for extra lightness)
50 g granulated sugar
10–12 g baking powder
¼ tsp (1–2 g) baking soda
5–6 g fine sea salt (or 1½ tsp Diamond Crystal kosher)
1 tsp (5 ml) pure vanilla extract

INSTRUCTIONS

In a large bowl, whisk sourdough discard, eggs, buttermilk (or milk), and melted butter until smooth.
In a separate bowl, whisk flour, sugar, baking powder, baking soda, salt, and vanilla.
Pour wet into dry and mix until just combined, a few lumps are fine (overmixing = tough waffles)
Preheat waffle iron to medium-high. Lightly grease if needed.
Scoop ⅓–1 cup batter per waffle (adjust to your iron size). Cook 4–6 minutes until deep golden and crisp.
Transfer to a wire rack; never stack hot waffles, or they go soggy!
Cool completely on a wire rack. Store in an airtight container in the fridge up to 3 days or freezer up to 3 months (layer with parchment). Reheat straight from frozen in a toaster or 180°C oven for 5 minutes. They crisp up perfectly!

NOTES

Optional add-ins (stir in just before cooking): – 100 g chocolate chips or rainbow sprinkles – 100 g fresh or frozen blueberries – 1 tsp cinnamon

Tips & Variations

Add cooked chicken, sautéed shrimp, or sliced mushrooms directly into the sauce before tossing with pasta for a heartier, more filling meal.
A pinch of red chili flakes added with the garlic brings a welcome kick without overpowering the creaminess.
Use freshly grated parmesan — it melts far more smoothly than pre-shredded, which can turn grainy.
Next time your starter jar is full, don’t toss it, fire up the waffle iron instead. Your family (and your sourdough culture) will thank you.
