In a medium bowl, toss together all ingredients until almonds are well coated.
3 cups whole raw almonds, 2 tablespoons extra virgin olive oil, 1 teaspoon fine sea salt, 1 teaspoon crushed dried rosemary
Spread into a single layer on a large rimmed baking sheet. I usually use my 13 x 18 inch sheet pan.
Roast for 10 minutes, stir, and continue roasting for another 10 minutes. Watch closely during the last 10 minutes to make sure they don't get too brown. Oven temperatures vary widely.
Cool completely on baking sheet before storing in an airtight container.
