Step 1

Preheat oven to 400 F. (205 C. ) As the oven is preheating rinse the asparagus in cold water. Trim the very bottoms of the stalks then use a vegetable peeler to peel away the tough outer skin of the ends.

Step 2

Line a baking sheet with foil and spray the foil with vegetable oil. Arrange the asparagus in a single layer on the baking sheet. Drizzle the stalks with olive oil, and sprinkle with the salt, pepper, and garlic. Squeeze half a lemon over the asparagus.

Step 3

Rub the spears so that they are evenly coated. Arrange them again in a single layer.

Step 4

Bake in the preheated oven until just tender about 12 to 15 minutes. Take the asparagus out and give the baking sheet a little shake or use a spatula to rearrange the spear. Return to the oven for 5 minutes more.

Step 5

Squeeze the other lemon half over the asparagus and sprinkle with a little more Parmesan if desired.

Step 6

Serve immediately.
