Preheat the oven to 425 F. Take an asparagus spear and snap the bottom off. The asparagus will snap at the point where the end is too fibrous to eat. Use this as a gauge to trim the other spears to the same length. Drizzle the asparagus with the olive oil. Massage the spears with your hands or move them around with tongs.
Step 2
Sprinkle the spears with kosher salt and place the sprigs of thyme on top and Roast for 8 minutes or until the asparagus are al dente and bright green.
Step 3
Taste and add extra salt to taste. Grate some fresh lemon zest on top and squeeze 1 tsp of lemon juice on top. Serve immediately.
