1. Preheat your oven to 175°C.

2. In a large bowl, combine the almonds, olive oil, rosemary, and sea salt. Toss well to coat the almonds evenly.

3. Spread the almonds in a single layer on a baking sheet lined with parchment paper.

4. Place the baking sheet in the preheated oven and roast the almonds for about 12-15 minutes, or until they turn golden brown and fragrant. Stir the almonds once or twice during the roasting process to ensure even browning.

5. Remove the baking sheet from the oven and let the almonds cool completely before serving.

6. Once cooled, transfer the roasted almonds to an airtight container for storage. They can be stored at room temperature for up to two weeks.
