Preheat your oven to 425°F (220°C). A hot oven is crucial for that desired crunch. You want the asparagus to roast, not steam.

Wash 1 lb. of fresh asparagus under cold water. Trim the woody ends by bending each spear until it naturally breaks, discarding the tough ends. You can easily identify where they snap.

In a large bowl, combine the asparagus with 1 tablespoon of extra virgin olive oil. Toss them gently to coat.

Next, add ½ teaspoon sea salt, ¼ teaspoon ground black pepper, and ½ teaspoon onion powder. Toss again to ensure each spear is well-seasoned.

Spread the seasoned asparagus evenly on a baking sheet lined with parchment paper. Make sure they’re in a single layer, not cramped together. This helps them roast properly and achieve that irresistible crispness.

Place the baking sheet in your preheated oven. Roast for 10-15 minutes, depending on how thin or thick your asparagus spears are.

You want them to be tender yet crispy, so keep an eye on them. Halfway through, give them a quick shake for even cooking.

Once they’re roasted to perfection, remove them from the oven. Immediately sprinkle with 2 tablespoons of finely grated Parmesan cheese, ½ teaspoon of red pepper flakes, and 1 tablespoon of lemon zest.

For an added flourish, drizzle 1 tablespoon of aged balsamic vinegar reduction over the top. Toss lightly to combine if you’d like.

Transfer the crispy roasted asparagus to a serving platter. You can garnish it with a sprinkle of more Parmesan if you’re feeling extra fancy. Serve while warm and watch your guests dig right in!
