This keto biscotti recipe tastes just like traditional biscotti with a nostalgic, crisp cookie and rich anise flavor, but just 2g net carbs!

Sugar Free Biscotti

My dad has always loved traditional Italian biscotti. Growing up, he would tell me stories about his grandmother in Italy making huge trays of almond biscotti during the holiday season, placing them on a wire rack near the window so the cool winter air could help dry them out. 

He remembers that distinct aroma — toasted almonds, anise, and that warm buttery smell that drifted through the whole house. Every Christmas, she served them next to a cup of coffee, but he always laughs and says that in Italy, “We dipped them in wine too!”

So when his birthday rolled around this year, I wanted to surprise him with something special — a keto almond biscotti recipe that captures all the flavors of the real thing, but fits our low-carb lifestyle.

I adapted my chocolate almond biscotti recipe since my dad isn’t a fan of chocolate and transformed it into a crisp, twice-baked, old-world cookie with the perfect crunchy texture.

And let me tell you… he took one bite and his face lit right up.

He said, “Brenda… this tastes like Nonna’s!”

Mission 100% accomplished.

These homemade biscotti are everything you love about the classic – the crisp cookie edges, the rich almond flavor, and that unmistakable hint of anise that only real Italian biscotti cookies have.

And yet, they are completely sugar-free, grain-free, and keto-friendly.

No wheat flour, no sugar alcohol aftertaste, and no complicated steps. Just simple, wholesome baking ingredients and a crunchy cookie that’s perfect for dunking.

They’re wonderful around the holiday season, perfect next to your morning coffee, and so easy to store in an airtight container for weeks.

Why You’ll Love This Keto Anise Almond Biscotti

✔ 2 g net carbs per biscotti ( All nutritional information is on the printable recipe card, bottom of this page)

✔ Gluten-free, sugar-free, low-carb

✔ Classic Italian flavor with anise + almond

✔ Perfect for dunking in coffee, espresso, or even wine says my dad!

✔ Uses basic keto baking staples like almond flour, whey protein, and monk fruit

✔ Keeps its crunchy texture for weeks — just like the real thing

✔ Makes a thoughtful homemade gift

Many regular biscotti recipes rely on all-purpose flour or sugar to get that iconic crisp cookie texture, but this version uses a combination of almond flour, a little bit of unflavored whey protein powder, which together mimic that dry, crunchy cookie feel essential to a true Italian biscotti.

You also don’t need any fancy equipment. Just a mixing bowl or stand mixer, a baking tray or cookie sheet, some parchment paper, and a serrated sharp knife for slicing through the almonds once the first bake is complete.

Swapping Low Carb Sweetener

I used Monk Fruit sweetener in this recipe because it provides that crisp texture for a typical biscotti.

I found that adding another sweetener like the vanilla liquid stevia helps there to be no aftertaste when combining both and adds a nice subtle sweetness. 

I do not recommend using Allulose sweetener because that will not produce a crisp biscotti. Allulose has a great way of keeping baked goods chewy and ice cream soft, so it’s not the ideal sweetener in this recipe.

Tips for Perfect, Authentic Biscotti

Toast the Almonds

This step creates deeper, richer almond flavor and that classic rich flavor biscotti is known for.

Let the Loaf Cool Before Slicing

Warm biscotti crumble — a fully cooled biscotti log slices beautifully.

Cut Slowly, With a Serrated Knife

Especially important when slicing through whole almonds or toasted nuts.

Don’t Rush the Second Bake

The second bake removes moisture and gives you that firm, crunchy biscotti texture.

Store Properly

These crunchy biscotti stay crisp for weeks in a glass airtight container at room temperature.

Ingredient Swaps & Variations

Using different extracts you can really transform these almond flour biscottis into great recipe into a variety of different flavors. 

Orange Anise Biscotti

Add lemon zest or orange zest for a fresh citrus flavor.

Double Almond Biscotti

Replace the anise extract with 2 teaspoons almond extract or use 1 teaspoon vanilla extract.

Chocolate-Dipped Biscotti

Melt some sugar-free chocolate or dark chocolate and dip one end of each cooled biscotti.

White Chocolate Drizzle

Use melted sugar-free white chocolate for a festive holiday look.

Swaps for Protein Powder

You may use egg white protein powder, but whey gives the best crunch.

Nut Variations

Try pistachios, hazelnuts, or a mix of whole almonds and slivered almonds.

What to Serve With Biscotti

These low-carb biscotti cookies are perfect with:

• Cappuccino
• Hot espresso
• Morning coffee
• Sugar-free hot chocolate
• Black tea or herbal tea
• And yes… a small glass of dry wine (my dad insists this is the true Italian way!)

They also make wonderful gifts during the holiday season — just package them in a cute tin or mason jar and attach a recipe card.

Keto Classic Italian Biscotti

When I handed these biscotti to Dad for his birthday, he couldn’t stop smiling. He said they tasted “just like the real thing” — the classic biscotti he grew up eating in Italy, the ones his mother made every December.

Moments like that are why I love creating sugar-free, low-carb versions of nostalgic foods… you get the joy without the sugar crash.

I hope these biscotti cookies bring joy to your home too — whether you enjoy them with your morning coffee, give them as holiday gifts, or recreate cherished family traditions.
