Ingredients for Air Fryer Savory Keto Almond Flour Biscotti with Rosemary and Parmesan

Instructions

Preheat air fryer to 320°F (160°C) for 5 minutes.
In a large bowl, mix almond flour, Parmesan cheese, baking powder, sea salt, rosemary, garlic powder, and black pepper until combined.
In a separate bowl, whisk eggs and olive oil until smooth.
Add wet ingredients to dry and mix thoroughly until a sticky dough forms that holds together when pressed.
Shape dough into a 10-inch long, 2-inch wide log on parchment paper.
Carefully transfer the dough log to the air fryer basket; cut in half if needed to fit without overcrowding.
Air fry at 320°F (160°C) for 12 minutes.
Remove and let cool on a wire rack for 5 minutes.
Slice the log diagonally into 1/2-inch thick biscotti using a sharp serrated knife.
Place biscotti slices cut-side down in a single layer in the air fryer basket.
Air fry for an additional 6 minutes, flipping halfway, until golden brown and crisp.
Cool completely on a wire rack before serving for maximum crunch.
Store leftovers in an airtight container at room temperature for up to 5 days.

Reheat leftovers at 325 F to 350 F in a single layer until hot and crisp again. Add fresh herbs, citrus, or sauce after reheating.
