Preheat your oven to 425°F (220°C). Lightly spray a baking sheet with nonstick cooking spray to prevent sticking. The high temperature helps caramelize the asparagus while keeping it tender inside.

2. Prepare the Asparagus

Arrange the trimmed asparagus spears in a single layer on the prepared baking sheet. Avoid overcrowding to ensure even roasting.

3. Make the Garlic Oil

In a small bowl, mix together olive oil, minced garlic, salt, and black pepper until well combined. This fragrant mixture enhances the asparagus with bold, savory flavors.

4. Season the Asparagus

Drizzle the garlic-infused olive oil over the asparagus and toss gently to coat evenly. Using your hands or tongs, ensure each spear is well covered.

5. Roast the Asparagus

Place the baking sheet in the oven and roast for 10-15 minutes until the asparagus turns bright green and is tender when pierced with a fork. The roasting time may vary based on the thickness of your asparagus.

6. Add the Cheese

Remove the asparagus from the oven and sprinkle shredded mozzarella cheese evenly over the spears. Return to the oven and broil for 4-5 minutes until the cheese is melted and golden brown. Keep a close eye to prevent burning.

7. Final Touches

Remove from the oven, adjust seasoning if needed, and serve immediately. The cheese should be bubbly and slightly browned for the perfect finishing touch.
