Begin by preheating the oven to an exact temperature of 425°F (220°C). Subsequently, apply a thin coating of nonstick cooking oil spray to a baking sheet to prevent any sticking.

Position the asparagus spears uniformly on the previously prepared baking sheet. Once done, set aside momentarily.

Proceed to combine the olive oil, finely minced garlic, salt, and freshly cracked black pepper in a small mixing bowl. Ensure they are blended thoroughly.

Delicately drizzle the aforementioned mixture over the asparagus, ensuring that each spear is uniformly coated.

Insert the baking sheet into the oven, allowing the asparagus to roast for a duration of 10-15 minutes. One should monitor the asparagus until it adopts a vibrant hue and reaches the precipice of tenderness.

Upon removal from the oven, garnish the asparagus with the finely shredded mozzarella cheese. Following this, place it back into the oven, utilizing the broil or grill setting. The goal is to witness the cheese undergoing a melting process until it obtains a golden appearance, typically within 4-5 minutes.

After the cooking process, one may adjust the salt and pepper seasoning to their precise preference. It is imperative to serve the dish promptly to maintain optimum taste and texture.
