Preheat and Prepare the Pan: Set your oven to 180°C (350°F) to preheat while you get the almonds ready. Line a small baking tray with parchment paper to keep the nuts from sticking and make cleanup quick and easy.
Coat the Almonds: In a medium mixing bowl, combine the almonds, olive oil, cayenne pepper, and salt. Toss everything thoroughly until each almond is evenly coated with the spicy seasoning mix. This ensures balanced flavor in every bite.
Arrange and Roast: Spread the seasoned almonds in a single layer on the prepared baking tray. Roast them in the preheated oven for 15 minutes, turning them halfway through to promote even browning and prevent burning.
Cool and Serve: Once roasted, remove the tray from the oven and allow the almonds to cool completely for a crisp, crunchy texture. Enjoy them warm as a snack, or store them in an airtight container once fully cooled for later munching.
