Ingredients

Servings 12
  • 2 cups almond flour (blanched, finely ground)
  • 1/2 cup erythritol or preferred low-carb sweetener
  • 1 tsp baking powder (gluten-free)
  • 1/4 tsp salt
  • 2 large eggs, room temperature
  • 1 tbsp fresh lemon zest (about 1 lemon)
  • 1 tsp fresh rosemary, finely chopped
  • 1 tsp vanilla extract
  • 1 tbsp coconut oil, melted
  • extra almond flour for shaping

Instructions

  1. Preheat your oven to 325°F (163°C). Line a baking sheet with parchment paper.
  2. In a large bowl, whisk together almond flour, erythritol, baking powder, and salt until well combined.
  3. In a separate bowl, beat the eggs lightly, then add lemon zest, chopped rosemary, vanilla extract, and melted coconut oil. Mix well.
  4. Pour the wet ingredients into the dry ingredients and stir until a sticky dough forms. If dough feels too sticky, dust hands with almond flour to help shape.
  5. Divide the dough in half and on the parchment paper, shape each half into a log about 10 inches long and 2 inches wide, flatten slightly.
  6. Bake for 15 minutes until the logs are firm to the touch and slightly golden.
  7. Remove from the oven and let cool for 10 minutes. Reduce oven temperature to 275°F (135°C).
  8. Using a serrated knife, slice each log diagonally into 1/2 inch thick biscotti pieces.
  9. Place biscotti cut-side down on the baking sheet. Bake for another 10 minutes, then flip and bake for 10 more minutes or until crisp and golden.
  10. Remove from oven and cool completely on a wire rack before serving.

Frequently Asked Questions

To customize this gluten-free low-carb almond flour biscotti recipe for different dietary needs or ingredient availability, try these ingredient substitutions:

  • Almond Flour: For nut-free alternatives, substitute with hazelnut flour or sunflower seed flour while keeping it gluten-free and low-carb; results may vary.
  • Low-Carb Sweetener: Erythritol can be swapped with monk fruit sweetener or stevia blends for another keto-friendly option.
  • Eggs: Use a vegan replacement by mixing 2 tablespoons flaxseed meal with 6 tablespoons water per egg and allowing to gel.
  • Coconut Oil: Substitute melted coconut oil with avocado oil or light olive oil to maintain dairy-free status.
  • Baking Powder: Confirm your baking powder is gluten-free or make your own using cream of tartar and baking soda.

These variations maintain the biscotti’s delightful taste and texture while accommodating vegan, nut-free, or other dietary preferences.

Allergen Overlap Note

While our gluten-free baking recipes on Freeflourish are thoughtfully crafted to exclude gluten-containing ingredients, please be aware of potential cross-contamination risks. Many gluten-free baking components, such as almond flour and gluten-free baking powder, may be processed in facilities handling wheat, nuts, or dairy.

If you have severe allergies or sensitivities to gluten, nuts, dairy, or other allergens present in some gluten-free recipes (including tags like dairyfree, nutfree, and paleo), carefully check ingredient labels for warnings about shared equipment or facilities.

To maintain the safest gluten-free cooking environment:

  • Use designated kitchen tools and utensils exclusively for gluten-free recipes.
  • Thoroughly clean all surfaces before baking.
  • Keep gluten-free ingredients stored separately from allergenic products.
  • Whenever possible, source certified allergen-free or single-ingredient products.

These precautions are especially important for family-friendly, quick & easy, and holiday & seasonal recipes where cross-use of kitchen equipment is common.

Thank you for prioritizing safety while enjoying our wholesome, delicious gluten-free meals and treats!

Texture Expectations

Gluten-free almond flour biscotti, such as this low-carb lemon and rosemary recipe, naturally have a different texture than traditional wheat biscotti. Without gluten, expect a denser, slightly crumbly bite combined with the characteristic crispness delivered by the twice-baking process.

The almond flour lends a moist, rich crumb that holds together well but is more delicate when slicing. Handle the dough gently and use a sharp serrated knife to cut biscotti evenly and reduce crumbling. The first bake firms up the logs, while the final baking creates the crisp, golden exterior typical of biscotti.

Thanks to the dairy-free coconut oil, this recipe maintains tenderness without heaviness, lending subtle moisture and a slight chew from natural almond oils, balanced by crisp edges.

Texture variations depend on baking time and slice thickness: thinner slices yield more delicate crunch, thicker slices are chewier and more substantial. Cooling completely on a wire rack ensures the perfect balance of crunch and tenderness.

Overall, expect a flavorful, family-friendly biscotti with a satisfying crumbly interior and crisp finish—ideal as a low-carb dessert or snack to enjoy with coffee or tea.

Dining With Non Gf Family Note

Preparing gluten-free meals like these almond flour biscotti for your family alongside members who eat gluten can be smooth with mindful habits. Prevent cross-contamination by using separate utensils, cutting boards, and storage containers for gluten-free ingredients. Clean all surfaces thoroughly before baking, and consider baking gluten-free items first or using separate cooking zones.

For shared kitchen appliances, designate gluten-free toasters or frying pans if possible, or use toaster bags and clean pans well. Store gluten-free flours and snacks clearly labeled and separately.

These simple tips ensure everyone at your table can enjoy delicious gluten-free snacks or desserts whether it’s a quick & easy family-friendly breakfast, holiday & seasonal treat, or everyday snack. Safe kitchen practices foster inclusive dining for diverse dietary needs.
