In a separate bowl, whisk together:

Stir in the fresh lemon zest.

Step 4: Combine the Dough

Gradually add the dry ingredients to the wet mixture.

Mix gently until a soft dough forms.

Fold in any optional add-ins such as almonds, pistachios, white chocolate chips, or poppy seeds.

Avoid overmixing to keep the biscotti tender.

Step 5: Shape the Dough

Lightly flour your hands.

Divide the dough into two equal portions.

Shape each into a log approximately:

  • 10 inches long
  • 3 inches wide
  • 1 inch thick

Place the logs on the prepared baking tray, leaving space between them.

Step 6: First Bake

Frequently Asked Questions

Why are biscotti baked twice?

The second bake removes moisture, creating the signature crisp texture that makes biscotti perfect for dipping into coffee or tea and helps them stay fresh longer.

Can I use bottled lemon juice?

Fresh lemon juice and zest provide the best flavor. Bottled lemon juice can be used in a pinch, but freshly grated zest is highly recommended.

Can I make Lemon Biscotti without nuts?

Yes. This recipe is delicious on its own and can be customized with chocolate chips, dried fruit, or poppy seeds instead of nuts.

Why did my biscotti crumble while slicing?

The loaves may have cooled too much before slicing. For best results, slice them while they are still slightly warm using a serrated knife.

Can I glaze Lemon Biscotti?

Yes. Once the biscotti have cooled completely, drizzle them with a simple lemon glaze made from powdered sugar and fresh lemon juice for an extra burst of citrus flavor.
