Sourdough Biscotti! Crunchy almond cookies enriched with a cup of sourdough discard. These sourdough cookies are perfect for dunking into coffee, espresso or dessert wine.

I love biscotti because they really are easy to make and they keep for weeks. They also happen to be a great vehicle for using your sourdough discard. (Check out this recipe for Almond & Anise Biscotti if you don’t have sourdough discard available.)
If you don’t already have one, I can show you how to make a sourdough starter and how to feed a sourdough starter.

FAQs about Sourdough Biscotti:
Yes. To work ahead, the dough logs can be wrapped and refrigerated for several days or frozen for several weeks. The baked loaves can also be held for a couple of days before slicing and baking the second time. Since biscotti keep so well, you can make the biscotti completely several days or even several weeks before you’re ready to serve them.
Since the word “biscotti” literally means “twice cooked” you do need to bake them twice to make “biscotti”. That being said, if you want a soft cookie, the pastry police won’t come to your house if you skip the second bake.
There is no need to refrigerate biscotti. In fact, the refrigerator could make the cookies soggy. The biscotti are best stored at room temperature in an airtight container.
I have kept biscotti in a cookie jar with a tight lid for several weeks.
Yes. But since they keep so well at room temperature there’s usually no need to freeze them. If you want to keep them more than two weeks they can be frozen for up to 3 months. You might want to re-toast them briefly after defrosting if they are less crunchy.

Sourdough Biscotti
Crunchy almond biscotti cookies enriched with a cup of sourdough discard. Perfect for dunking into coffee, espresso or dessert wine.
Ingredients
- 1 cup (8 oz, 224g) sourdough discard
- 2 large eggs, plus 1 for egg wash
- 1/4 cup (2 oz, 60 ml) olive oil
- 2 teaspoons vanilla extract
- Grated zest from 2 large lemons
- 3 cups (15 oz, 420g) all purpose flour
- 1 3/4 cups (14 oz, 392g) granulated sugar, separated
- 1 tablespoon baking powder
- 1/2 teaspoon table salt
- 1.5 cups (8 oz, 224g) toasted almonds, roughly chopped into large chunks
Instructions
- In a glass measuring cup combine the discard, 2 eggs, olive oil, vanilla and lemon zest, set aside. In a mixing bowl combine flour, 1 1/2 cups of sugar, baking powder and salt. Mix the dry ingredients for 30 seconds to combine.
- Add the egg mixture to the dry ingredients and mix until almost combined. Add the almonds and mix until almost combined. Turn the dough out onto a lightly floured surface and finish mixing by hand until all the flour is absorbed.
- Cover the dough with plastic wrap and allow it to rest for 15-20 minutes. Preheat the oven to 350°F. Line a 1/2 sheet pan with parchment paper or a silicone baking mat.
- Split the dough into 2 equal portions. Use your hands to roll each piece of dough to a log 13" long x 2" wide. Set the logs onto the sheet pan, leaving at least 3" between them. Brush the logs with egg wash and sprinkle with the last 1/4 cup of granulated sugar.
- Bake until golden brown and feels firm when pressed in the middle, about 35 minutes. Allow the cookies to cool completely.
- Use a serrated knife to cut each log into 1/2" slices on a slight diagonal. Lay the cookies flat on the sheet pans and bake 10-12 minutes until toasty and golden brown (see note). Flip the cookies over and bake on the other side for another 10-12 minutes. Cool on a wire rack.
- Store in a cookie jar for up to 2 weeks.
Notes
If you like your biscotti super-crunchy bake the sliced cookies for the longer time, bake for the shorter time if you like them a little softer.
To work ahead: the dough logs can be wrapped and refrigerated for several days or frozen for several weeks.

Amazing recipe. I make these once a week. Everybody loves them. Love it that they’re dairy free.

Was hoping for a good way to use discard. These are a great texture, but agree with all below who share that more flour is required to get there....even if measuring by weight. However these are way too sweet, IMHO, and I can't taste the Sourdough at all.

This morning was the 7th time that I have made this recipe. This time I baked them in my King Arthur mini scone pan, which was perfect.
