Lemon Blueberry Sourdough Waffles

There's something about Sunday mornings that makes me want to pull out the waffle iron, and this recipe came about on one of those lazy, slightly chaotic days when I realized I had sourdough starter that needed rescuing. The smell of lemon and blueberries hitting the hot iron is pure magic—it fills your kitchen with this bright, summery promise that makes everyone shuffle toward the kitchen table faster than usual. I've learned that the tanginess of sourdough plays beautifully against sweet maple and tart lemon, creating waffles that taste both homey and a little bit fancy.

I made these for my neighbor one Saturday after she helped me figure out why my starter kept acting temperamental, and I watched her face light up when she bit into the first wedge. The maple yogurt had cooled just enough to be creamy but still warm, and she actually closed her eyes for a second—which is either the highest compliment or a sign I've finally figured out what I'm doing in the kitchen. Since then, this recipe has become my go-to when I want to show someone I care but don't have the energy for a full production.

Ingredients

• Active sourdough starter (1 cup): Use whatever you have—fed, unfed, or the discards you'd normally toss—it creates incredible tanginess and lift without commercial yeast.
• Whole milk (1 cup): This keeps the waffles tender; don't skip it for water or you'll lose that subtle richness.
• All-purpose flour (1 cup): Measure by spooning into your cup and leveling, not scooping directly from the bag, to avoid packing it down.
• Granulated sugar (2 tbsp): Just enough sweetness to balance the tartness without making these taste like dessert masquerading as breakfast.
• Egg (1 large): Binds everything and adds structure—use room temperature if you want your batter to come together smoothly.
• Unsalted butter (3 tbsp, melted and cooled): Let it cool slightly so the egg doesn't scramble when you mix everything together.
• Vanilla extract (1 tsp): This small amount deepens the flavor without announcing itself too loudly.
• Lemon zest (1 tsp, finely grated): Use a microplane for the brightest, most delicate bits—it makes a real difference in the final flavor.
• Fresh lemon juice (1 tbsp): Squeeze from a fresh lemon right before using; bottled juice tastes flat by comparison.
• Baking powder (1 tsp) and baking soda (½ tsp): Together these create the lift and crispness; don't swap one for the other without adjusting amounts.
• Salt (¼ tsp): A tiny pinch that makes everything taste more like itself.
• Fresh blueberries (1 cup): Room temperature works best, as cold berries can make your waffle iron temperature drop mid-pour.
• Greek yogurt (1 cup, full-fat or low-fat): Full-fat is noticeably creamier, but low-fat works if that's what you have.
• Pure maple syrup (3 tbsp for yogurt, plus more to serve): Don't use the pancake syrup from the back of the cabinet—real maple syrup tastes like a completely different ingredient.

Instructions

Build your base:

In a large bowl, whisk the sourdough starter, milk, and flour together until the mixture looks mostly smooth with just a few small lumps remaining. Let it sit for 10 minutes—this rest time lets the flour fully hydrate and the sourdough begin working its magic on the batter.

Prep your wet ingredients:

In a separate bowl, whisk the egg, cooled melted butter, vanilla, lemon zest, and fresh lemon juice together until everything is evenly combined and pale.

Bring it all together:

Add the sugar, baking powder, baking soda, and salt to your rested batter, then pour in the egg mixture. Stir everything until just barely combined—lumps are your friends here, as overmixing creates tough, dense waffles instead of light, tender ones.

Fold in the fruit:

Gently fold the fresh blueberries into the batter with a spatula, handling them as little as possible to keep them whole and prevent the batter from turning gray.

Heat your iron:

Preheat your waffle iron according to the manufacturer's instructions and give it a light coating of cooking spray or a brush of melted butter if it tends to stick.

Cook with confidence:

Pour about ½ to ¾ cup of batter into the center of your preheated iron—the amount depends on your specific waffle maker, so you might need to adjust on the first one. Close the lid and resist the urge to peek; cook for 4 to 5 minutes until the edges stop steaming and the waffle is deep golden brown and crispy.

Prepare the yogurt topping:

While the waffles cook, whisk together the Greek yogurt and maple syrup in a small bowl until smooth and swirled with golden streaks.

Serve immediately:

Place finished waffles on a serving plate and top generously with maple yogurt, a small handful of fresh blueberries, and an extra drizzle of maple syrup. A whisper of fresh lemon zest on top adds a final bright note.

Save

There was one morning when my mom came to stay and I made these for her before she'd even finished her coffee, and she sat at my kitchen table in her old robe just nodding quietly. Later she told me it was the tartness—the way the sourdough and lemon worked together to cut through the maple—that reminded her why she loves breakfast food, and I realized this recipe had done something small but real. Food memories are funny that way; they slip into moments you weren't expecting them to matter.

The Secret to Crispy Edges

If you want your waffles to stay crispy all the way through and not get soggy by the third or fourth batch, place the finished ones on a wire rack in a low oven set to 200°F while you finish cooking the rest. This keeps them warm without steaming them back to soft, and by the time everyone sits down, the whole batch is still golden and crackling.

Switching Things Up

I've played with this recipe in different seasons and moods—sometimes substituting honey or agave for the maple syrup in the yogurt when that's what feels right, or using frozen blueberries in winter when fresh ones taste like nothing. The beauty of sourdough waffles is that they're flexible enough to handle small changes while still tasting like themselves, which is exactly what you want from a recipe you'll make again and again.

Pairing and Serving Ideas

These waffles shine at brunch tables with a glass of Prosecco or a citrusy herbal tea, but I've also found they're equally at home on a quiet weekday morning when you just need something that tastes a little special. The tanginess pairs beautifully with scrambled eggs and smoked salmon if you're feeding a group, or stands completely alone if you're making breakfast for one and want to linger over it.

• For a summer morning, serve alongside fresh berries and a simple green salad with a lemon vinaigrette to keep the meal feeling light.
• Cold leftover waffles (if there are any) can be crisped in the toaster and topped with almond butter and jam for an easy next-day breakfast.
• This recipe doubles easily, so don't hesitate to make extra batter if you're feeding a hungry crowd.

These waffles have become my answer to the question of what to make when I want breakfast to feel like a small celebration. There's real comfort in pulling out the waffle iron and knowing that 20 minutes later, you'll have something that tastes both homey and a little bit fancy.
