Preheat your oven to 425°F. Rinse the asparagus thoroughly and gather them into a neat bundle. Trim off the tough, fibrous bottoms—about an inch or so. Arrange the asparagus spears in a single layer on a rimmed baking sheet. Ensure they are as dry as possible to avoid any steaming during roasting.
Drizzle the asparagus generously with olive oil, ensuring even coverage. Season with a liberal amount of kosher salt and freshly ground black pepper.
Place the baking sheet in the preheated oven and roast the asparagus for approximately 10 minutes. The high temperature is crucial for browning the exterior while maintaining a slight crunch. Aim for a tender yet firm texture. Enjoy!
