Preheat your toaster oven or oven to 450ºF.
Lay pecans in a single layer on a parchment lined baking sheet.
Sprinkle a few teaspoons of rosemary leaves on top.
Drizzle with maple syrup, enough to coat them and leave a bit extra on the pan for them to sizzle in.
Sprinkle with a few pinches of sea salt.
Mix it all up.
Bake for 5-7 minutes, checking regularly to make sure they don’t burn.
Remove when the maple syrup is bubbling and they’re just golden.
Let cool, turning a bit to coat with any remaining maple, rosemary, and sea salt.
