A Bright Twist on a Classic Lemon Loaf

This sourdough lemon loaf is soft, moist, and full of bright citrus flavor with a subtle tang from sourdough discard. It’s the kind of bake that feels comforting and fresh at the same time—perfect for slow mornings, tea time, or gifting.

If you’ve been wondering what to do with extra sourdough discard, this recipe is one of the easiest and most delicious ways to use it.

Ingredients

Dry Ingredients

  • 1 ½ cups all-purpose flour
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • ¼ teaspoon salt

Wet Ingredients

  • ½ cup sourdough discard (unfed)
  • ½ cup plain Greek yogurt or sour cream
  • ½ cup melted butter (or neutral oil)
  • ¾ cup sugar
  • 2 large eggs
  • Zest of 2 lemons
  • ¼ cup fresh lemon juice
  • 1 teaspoon vanilla extract

Lemon Glaze (Optional but Recommended)

  • 1 cup powdered sugar
  • 2–3 tablespoons fresh lemon juice
  • Optional: extra lemon zest for topping

Instructions

1. Prep

Preheat oven to 350°F (175°C). Line a loaf pan with parchment paper or lightly grease it.

2. Mix dry ingredients

In a bowl, whisk together flour, baking powder, baking soda, and salt.

3. Mix wet ingredients

In a separate bowl, whisk sourdough discard, yogurt, melted butter, sugar, eggs, lemon zest, lemon juice, and vanilla until smooth.

4. Combine

Gently fold dry ingredients into wet ingredients. Mix just until combined—do not overmix.

5. Bake

Pour batter into loaf pan and bake for 45–55 minutes, or until a toothpick inserted in the center comes out clean.

6. Cool

Let cool in the pan for 10–15 minutes, then transfer to a wire rack.

Lemon Glaze

Whisk powdered sugar and lemon juice until smooth and pourable.

Once loaf is completely cool, drizzle glaze over the top. Add extra zest if desired.

Tips for Best Results

  • Don’t overmix the batter—this keeps it tender
  • Room temperature eggs mix more smoothly
  • Use fresh lemon juice for best flavor
  • Let loaf cool fully before glazing (or it will melt off)
  • Discard works best when it’s unfed but not overly sour
