• Zest of 2 lemons – Offers bright citrus flavor, making the Lemon Biscotti sing.
• 2 cups all-purpose flour – The backbone of the dough, providing the perfect texture.
• ⅛ tsp salt – Enhances the overall flavor and balances sweetness.
• 1 teaspoon baking powder – Helps leaven the biscotti for that delightful puff.

How to Make Lemon Biscotti

Preheat your oven to 350°F. Get one cookie tray ready by lining it with parchment paper to ensure easy removal later.
Cream the butter and sugar together in a medium bowl. Use a hand mixer to mix until the mixture is light and fluffy. Incorporate the lemon zest and blend it seamlessly into the buttery goodness.
Add the eggs, mixing them in for about 1 minute. Make sure to scrape down the sides and bottom of the bowl to gather all the tasty bits.
Combine the flour, salt, and baking powder with the wet mixture. Gently mix on low speed until just incorporated. Stop mixing once you see no dry flour—scrape down the side again for good measure!
Dust your prepared cookie tray with flour. Carefully dump the dough onto the tray, forming it into a log shape, using more flour as needed to manage any stickiness.
Flatten the dough log to about ½ inch thick, creating a solid base for your biscotti.
Bake for about 30 minutes, until you see a puffed up, light golden brown top, and the texture feels firm to the touch.
Cool for 10 minutes on the tray. Use a serrated knife to slice the log into about 1-inch wide cookies on a diagonal.
Re-bake the cookies on their flat sides for 10 minutes. You can leave them longer if you prefer them extra crunchy.
Flip the cookies over and bake the other sides for another 10 minutes, adjusting the time based on how crispy you like them.
Remove from the oven and let the cookies cool back on the tray, letting the wonderful lemon aroma fill your kitchen.
For the Glaze: In a small bowl, mix the lemon juice with powdered sugar until smooth. Drizzle the glaze over cooled biscotti and let it dry for an irresistible finish.

Optional: Serve with a cup of hot tea for the perfect afternoon treat!

Storage Tips for Lemon Biscotti

Room Temperature: Store the Lemon Biscotti in an airtight container at room temperature for up to 2 weeks; they’ll stay crunchy and enjoyable for your afternoon snack.

Fridge: If you want to keep them longer, consider refrigerating the cookies in an airtight container for up to 1 month, but this may soften their crunchiness.

Freezer: For maximum freshness, freeze the Lemon Biscotti in a freezer-safe bag for up to 3 months. Just make sure to separate layers with parchment paper to prevent sticking.

Reheating: When ready to enjoy, you can re-crisp the biscotti in the oven at 300°F for about 10 minutes, perfect for reviving that delightful crunch!

Expert Tips for Lemon Biscotti

Use Fresh Lemons: Fresh lemon zest elevates the flavor of your Lemon Biscotti. Avoid using bottled lemon juice for the best taste.
Proper Mixing: Mix the dough gently to prevent tough biscotti. Over-mixing can lead to a chewy texture rather than a perfect crunch!
Slice with Care: Use a serrated knife to slice the log for clean edges. If the dough is too soft, chill it briefly before slicing.
Adjust Baking Time: Keep an eye on the cookies while re-baking to achieve your desired crispiness; bake longer for a crunchier biscotti.
Experiment with Flavors: Feel free to add nuts or dried fruits for a unique twist on this classic Lemon Biscotti recipe!

Make Ahead Options

These delightful Lemon Biscotti are perfect for busy home cooks looking to save time during the week! You can prepare the dough up to 24 hours in advance by mixing the wet ingredients and dry ingredients together, then shaping it into a log, wrapping it tightly in plastic wrap, and refrigerating it. This prevents the dough from drying out and ensures it’s just as delicious when you bake it. When you’re ready to enjoy your biscotti, simply slice and bake as instructed. You can also glaze them up to 3 days in advance; just store them in an airtight container to maintain freshness and flavor. Enjoy the convenience of having your snack ready to go!

Lemon Biscotti Recipe FAQs

How do I know when my lemons are ripe for zesting?
Absolutely! When selecting lemons for your Lemon Biscotti, look for ones that are bright yellow, heavy for their size, and have a smooth skin. Avoid any with dark spots or wrinkles, as these can indicate overripeness. The zest should have a fragrant and vibrant aroma; if the lemon smells fresh and citrusy, it’s perfect for zesting!

How should I store my Lemon Biscotti?
Very good question! To keep your Lemon Biscotti fresh, store them in an airtight container at room temperature for up to 2 weeks. This will maintain their delightful crunch. If you want to extend their life, you can refrigerate them in an airtight container for up to 1 month, though their crispiness may be affected.

Can I freeze Lemon Biscotti?
Absolutely! Freezing is a fantastic way to keep your Lemon Biscotti fresh. To do this, place the biscotti in a single layer on a baking sheet and freeze until solid. Then, transfer them to a freezer-safe bag, separating layers with parchment paper, and store for up to 3 months. When you’re ready to enjoy them, simply reheat in a 300°F oven for about 10 minutes to restore their crunch.

What should I do if my biscotti crumble or break while slicing?
If your Lemon Biscotti crumbles when you slice them, it might be due to slicing too soon after baking the log. For perfect slices, allow the biscotti log to cool for the full 10 minutes before cutting. If you encounter a particularly sticky log, try chilling the dough briefly in the fridge before slicing. This should give you cleaner cuts!

Are there any dietary considerations for Lemon Biscotti?
Great question! While traditional Lemon Biscotti contains eggs and butter, if you have dietary restrictions or preferences, there are substitutions you can try. Use a vegan butter alternative and flax eggs (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water per egg) for a plant-based version. Always check for any allergies related to specific ingredients!

How long will the optional glaze last once applied?
The glaze on your Lemon Biscotti is best enjoyed fresh, but any leftover glazed cookies can be stored in an airtight container for about 3-4 days. After that, the glaze may start to soften. If you’re planning to serve them over time, consider glazing just before serving to maintain the crispness of both the biscotti and the glaze!
