Heat a large cast-iron or heavy skillet over medium-high heat.
Add olive oil and heat for 30 seconds, tilting the pan so the oil coats the bottom.
Add the almonds and spread along the bottom. Leave for 1 to 2 minutes until they start to brown and become fragrant.
Use a spatula to stir the almonds around the pan. Sprinkle the salt over the nuts and stir again.
Continue cooking the almonds, stirring every 15 seconds or so, until they are nicely brown and have a deeply toasted flavor, about 5 minutes time in total.
Transfer to a piece of parchment paper until they've cooled to room temperature.
Store in a jar with a lid in the refrigerator.
