Preheat the oven to 350 degrees.
Combine the flour, baking soda, and salt in a mixing bowl. Stir well.
In another mixing bowl, combine the eggs, oil, and sugar. Add the almonds to the mix.
Combine the dry mix with the wet mix. Stir well until there are no visible lumps.
Lightly grease the baking trays using unsalted butter.
Transfer the dough onto your greased trays and divide the dough into four pieces.
Shape the halves into 12-inch-long logs.
Bake the dough for about half an hour, until firm.
Let it cool on a rack.
Once cooled, slice the logs again, this time in the shape of cookies, and bake again, for 15-20 minutes.
Let your biscotti cool to room temperature.
