This sourdough discard lemon loaf is a great way to use your discard. Sourdough bakers will appreciate the slight tang the discard gives this lemon loaf.

It’s finally spring and I thought it was time to bake something light and lemony! This sourdough lemon loaf is such an easy, no fuss recipe, and a great way to reduce kitchen waste by using sourdough discard.
I do recommend that you use fresh lemon juice for this recipe since you will also need lemon zest. I highly recommend making the glaze to go with this lemon loaf, it’s just not the same without it!
Ingredients needed
To make this sourdough lemon loaf, you will need:
- Sourdough discard: You will need one cup of unfed sourdough discard.
- Olive oil: You can also use another neutral oil.
- Eggs: You will need two large eggs for this recipe.
- All purpose flour: The base of the loaf batter.
- Sugar: To sweeten the loaf.
- Salt: You’ll need just half of a teaspoon of salt.
- Baking soda: To help the loaf rise.
- Lemon extract: Be sure to measure the lemon extract carefully, it can be quite strong if you add too much.
- Lemon: You’ll need a large lemon for lemon juice and zest.
For the glaze, you will need:
- Lemon juice: Again, I recommend using fresh lemon for this recipe.
- Confectioner’s sugar: Also called powdered sugar.
You will also need a well greased loaf pan (9 x 5 inch).
How to make
Begin by preheating your oven to 350 degrees. Grease a loaf pan (9 x 5 inch) and set it aside.
In a large mixing bowl, combine the wet ingredients (sourdough discard, olive oil, lemon juice, lemon zest, eggs, and lemon extract). Mix well with a large spoon.
Next, add in the dry ingredients (flour, baking soda, sugar, and salt). Mix well with a large spoon or hand mixer until everything is well combined.
Pour into the greased loaf pan. Bake for 45 to 50 minutes or until a toothpick comes out clean from the middle.
To make the glaze, combine the confectioner’s sugar and lemon juice in a medium bowl. Mix well with a hand mixer. Pour over the loaf once it has cooled.
Tips
- Be sure to make the glaze to top the lemon loaf with, the recipe just isn’t the same without it.
- Use a fresh and not bottled lemon juice for the best results.
- Carefully measure the lemon extract, it can be quite strong if you add too much.
- Do not use lemon juice and lemon extract interchangeably.
