What You’ll Need:

This Sourdough Discard Lemon Loaf ingredient list is intentionally simple—because good food doesn’t need to be complicated. Here’s what you’ll want on hand:

Ingredients for Sourdough Discard Lemon Loaf laid out on a kitchen counter
  • 1 cup sourdough discard (unfed and unfed discard works great here)
  • 1/2 cup granulated sugar (feel free to swap for coconut sugar if you prefer a subtle caramel note)
  • 2 large eggs (room temperature for best mixing)
  • 1/3 cup plain yogurt (full-fat is my go-to, but you can use plant-based for a dairy-free option)
  • 1/4 cup vegetable oil (or melted coconut oil for a hint of richness)
  • 1 tablespoon fresh lemon zest (you can find this zesting in the produce aisle—grab a firm, unwaxed lemon)
  • 3 tablespoons fresh lemon juice (about one medium lemon)
  • 1 teaspoon vanilla extract (optional, but it adds a warm balance to lemon’s brightness)
  • 1 1/2 cups all-purpose flour (I often swap half for whole wheat for a nuttier loaf)
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt

Quick note: No stress if you don’t have yogurt on hand—I often use sour cream in my Sourdough Discard Lemon Loaf instead. It keeps the crumb tender and tangy. Using sourdough discard as your base is also a budget-friendly move; no need for expensive starters and it helps reduce food waste.

For a shortcut when you’re pressed, zest and juice your lemon the night before, and keep it sealed in the fridge until baking day. This prep step saves time and keeps flavors bright.

Leftovers? This lemon loaf keeps well covered at room temperature for 2-3 days, or wrapped tightly in the fridge up to a week. I sometimes slice and freeze it for an easy snack later on.

For a little extra indulgence, I love adding a handful of poppy seeds or a sprinkle of finely chopped fresh rosemary to the batter. Both give a subtle twist that keeps this classic refreshing and interesting.

If you’re looking for a variation, you’ll find wonderful ideas on sites like Sourdough Lemon Loaf Cake from This Jess Cooks, which includes hints of almond extract and a light glaze. That kind of sweet finish is tempting if you want a citrus quick bread with a little extra flair.


Let’s Make It Together!

Here’s the step-by-step for a Sourdough Discard Lemon Loaf that feels like you’re baking side-by-side with me.

  • Preheat your oven to 350°F (175°C). Grease and flour a 9×5-inch loaf pan or line it with parchment paper. Getting your pan ready early helps keep the momentum flowing.
  • In a medium bowl, whisk together your sourdough discard and sugar. The discard lends a subtle tang that balances the sweetness—don’t skip this! It should start looking creamy and smooth.
  • Add the eggs one at a time, mixing well after each. This helps the batter bind nicely. If your eggs are cold from the fridge, take a moment to warm them in a bowl of hot water before cracking—they incorporate better.
  • Whisk in the yogurt (or your chosen substitute), oil, lemon zest, lemon juice, and vanilla extract. The lemon zest is where the magic hides; it brings fresh bursts of citrus in every bite. Your kitchen should be smelling like a lemon grove right now.
  • In a separate bowl, sift together the flour, baking powder, baking soda, and salt. This step keeps your loaf tender and fluffy. If you don’t have a sifter, just whisk the dry ingredients thoroughly to break up clumps.
  • Gradually fold the dry ingredients into your wet lemon mixture. Stop mixing as soon as you see no streaks of flour; overmixing can make your loaf dense. It’s okay if the batter looks a little thick.
  • Pour the batter into your prepared loaf pan and smooth the top with a spatula. Here’s where I used to overcomplicate things by poking holes for glazes or swirl additions. Turns out, a simple surface yields the best rise and crumb.
  • Bake in the middle rack for about 45-55 minutes. Start checking around 45 minutes with a toothpick inserted into the center; it should come out clean or with just a few moist crumbs.
  • Once baked, let the loaf cool in the pan for 10 minutes before transferring it to a wire rack. Cooling lets it set up properly—and the aroma continues to deepen.

While your Sourdough Discard Lemon Loaf is baking, it’s the perfect time to clean up or pour yourself a cup of tea. Baking is a little slower than weeknight dinners, but the payoff is worth every minute.

If your loaf cracks on top or sinks a bit in the middle, don’t worry. That’s just part of real-life baking! This cake is forgiving and still tastes fabulous.

For a quick finish, you can glaze your loaf with a simple mix of powdered sugar and lemon juice once cooled. It adds a nice touch without overwhelming the natural loaf flavor.

How I Love to Serve This!

Sliced Sourdough Discard Lemon Loaf served with fresh berries

This Sourdough Discard Lemon Loaf becomes a complete treat whether it’s breakfast on a slow weekend or a thoughtful snack for afternoon guests. I like mine sliced thick with a smear of unsalted butter. The lemon brightness pairs beautifully with the creaminess.

Sometimes, I serve it alongside a bowl of fresh berries or a dollop of Greek yogurt, which adds a cooling contrast to the citrus punch.

On busy mornings, a slice with a hot cup of coffee is my go-to. It’s nourishing enough to keep me satisfied but light enough not to weigh me down.

This loaf is also perfect for brunch gatherings or casual tea parties. A simple dusting of powdered sugar or a thin lemon glaze makes it feel a little extra special.

Leftovers? I’ve sliced leftover Sourdough Discard Lemon Loaf and toasted it gently with a drizzle of honey. It’s an unexpectedly delicious way to enjoy it the next day and cuts back on waste.

Seasonally, I’ve played with adding fresh thyme or lavender to the batter for a floral twist. It transforms the loaf into something beautifully unique for spring or summer.

Friends and family usually ask for this lemon loaf by name—its bright but gentle flavor is always a crowd pleaser. Want more ideas? Check out the Sourdough Discard Coffee Cake Muffins from Just Healthy Bites, which also explore easy sourdough baking with a sweet twist.


Common Questions Answered

Can I make this Sourdough Discard Lemon Loaf ahead for meal prep?
Absolutely! I often bake the loaf the day before and keep it tightly wrapped at room temperature. It tastes just as fresh the next day and makes quick breakfasts a breeze.
What if I don’t have all the ingredients for this Sourdough Discard Lemon Loaf?
No worries at all. If you’re missing yogurt, sour cream or even buttermilk works well. For the oil, melted butter is a simple swap. The key is to maintain the balance of wet and dry.
Can I use whole wheat flour instead of all-purpose?
Yes! I usually swap up to half for whole wheat to add depth without sacrificing texture. Your loaf might be a bit denser but still delicious and nourishing.
How can I adjust the flavor of this Sourdough Discard Lemon Loaf to my taste?
Add more lemon zest for brighter citrus punch or a touch of almond extract for a warm note. A handful of poppy seeds or crushed nuts also add nice texture and flavor.
Can I freeze this lemon loaf?
Definitely. Slice it first and freeze the pieces in an airtight container. Toast them straight from the freezer for an easy treat.
Will the sourdough discard affect the rise?
A little, but that’s part of the charm. This loaf uses baking soda and powder for lift, so it’s always fluffy. The discard adds moisture and flavor, especially that subtle tang you don’t get from regular quick breads.
Is this recipe good for beginners with sourdough discard usage?
Totally. It’s one of the easiest sourdough discard recipes because it doesn’t require feedings or active starter. Plus, it’s forgiving about timing and texture.

It’s a gentle way to get creative with sourdough discard usage without stress or perfection.

My Favorite Sourdough Discard Lemon Loaf Tips:
– Always use fresh lemon zest; it’s the key to that punchy citrus flavor.
– Don’t overmix the batter—stop when just combined for the best texture.
– Let your loaf cool fully before slicing to avoid crumbly edges.

As far as variations, I love the classic lemon version, but I also return to the lemon poppy seed twist and a rosemary lemon loaf for a savory hint. Each feels like a new chapter in the same nourishing story.
