Wash asparagus and dry in a clean kitchen towel. Snap woody ends off of each piece. (If you try to bend it close to the ends, it will naturally break.)
Place whole asparagus spears onto a baking sheet, drizzle with olive oil and sprinkle with salt and pepper. Toss to coat. Spread to create one even layer on the baking sheet and bake 10-15 minutes or until browned to your liking. (If you have very skinny asparagus, this might only take 5-10 minutes. If your asparagus is thicker, this will be 10-15 minutes.)
