Preheat oven to 325° F. and line a baking sheet with parchment paper.
In a medium sized bowl whisk together all of the ingredients except the almonds and 1/2 teaspoon of the rosemary. Add the almonds to the mixture and toss them until they are coated.
Pour the almonds out onto the prepared baking sheet and place them on the middle rack of the oven. Bake the almonds for 5 minutes then remove them and toss them around using a spatula.
Place the almonds back in the oven and bake them for another 12-15 minutes, tossing them around 2-3 more times. Remove the almonds from the oven and sprinkle on the remaining 1/2 teaspoon of rosemary along with another pinch of kosher salt. Let the nuts cool completely before serving.
Notes
Keep a close eye on the almonds while they bake to prevent them from burning.
