Preheat your oven to 400 degrees Fahrenheit (200 degrees Celsius) and prepare a baking sheet with parchment paper for easy cleanup.
Prepare The Asparagus:
Clean them as well as cut them by breaking the woody ends off from asparagus spears. Dry with tissue paper to achieve absolute crispiness.
Season The Asparagus:
Make a single layer of asparagus spears on the lined baking sheet. Lightly spray them with cooking spray olive oil to ensure uniform coverage. Sprinkle sea salt and garlic powder evenly over the spears.
Add The Parmesan:
Generously top the asparagus with shredded Parmesan cheese. Make sure each spear gets a cheesy coating for that golden, crispy finish.
Roast To Perfection:
For 12-15 minutes, roast the baking sheet in a preheated oven. The asparagus should have a tender-crisp texture garnished with half-caramelized and golden Parmesan.
Serve And Enjoy:
Remove the roasted asparagus to a serving plate, and serve hot as a side dish or snack to enjoy cheesy goodness.
