Preheat your oven to 425°F (220°C). This temperature is perfect for roasting and ensures your asparagus gets that lovely char. While it heats, grab a baking sheet and lightly grease it with nonstick cooking oil spray to prevent sticking.
Arrange the asparagus on the baking sheet in a single layer. It’s important they have space to roast evenly. Set them aside while you prepare the flavor-packed oil mixture.
In a small bowl, mix together olive oil, garlic, Kosher salt, and cracked pepper. This mixture is where the magic happens, allowing the flavors to coat each spear beautifully. Drizzle this oil mixture generously over the arranged asparagus, making sure to toss them to coat evenly.
Now, slide the baking sheet into the preheated oven. Roast the asparagus for about 10 to 15 minutes. You’ll want to watch for a vibrant green color and just a hint of tenderness, which indicates they’re ready to come out.
Once they're done roasting, remove the baking sheet from the oven and top the asparagus with mozzarella cheese. This is where it gets exciting! The cheese will melt and bubble, creating that irresistible topping.
Return the baking sheet to the oven and switch to broil. Keep a close watch as the cheese melts and becomes golden, which should take about 4 to 5 minutes. The smell will be incredible!
Finally, check the seasoning. Adjust with more salt and pepper if needed. Serve immediately while still warm and enjoy the delightful combination of flavors!
