This is my favorite way to cook asparagus.
-herbed rock salt*
-parmesean cheese block
Herbed rock salt consists of rock salt, olive oil, rosemary, and thyme. In a very small dish or container, combine salt, oil, and thyme. Crush (as best you can) rosemary and add to dish.
Preheat oven to 400 degrees. Wash asparagus. Cut off 1-2 inches of bottom of stems (the white/purple part). Lay out on baking sheet. LIGHTLY drizzle with olive oil. Take two pinches of herbed rock salt and rub over asparagus. Bake for 17-20 minutes (depending on the thickenss of the asparagus). When finished, remove and freshly grate parmesean cheese over top as garnish.
