Preheat your oven to 400°F (205°C). It’s important to have your oven nice and hot, so the asparagus roasts perfectly.
Lightly grease a baking tray or sheet with non-stick cooking oil spray. This will prevent the asparagus from sticking and ensure it becomes beautifully crisp.
Place the trimmed asparagus in a large bowl. Make sure to wash and dry them well so they roast instead of steam.
Add the melted butter, olive oil, minced garlic, grated parmesan, Panko breadcrumbs, parsley, salt, and pepper to the bowl. Use your hands to mix everything together. This step ensures that every spear is generously coated.
Transfer the asparagus and breadcrumb mixture onto the prepared baking sheet. Arrange them in a single, even layer. This allows for even cooking and crisping.
Bake in the oven for about 10 minutes. You'll want the asparagus to be just tender but still vibrant green.
Next, switch your oven to broil/grill for 2 to 3 minutes. Keep a close eye on them during this time. You're looking for that golden-brown crisp on the breadcrumbs.
Once they are nicely browned and the asparagus has reached your desired doneness, remove them from the oven.
Let the dish cool for a minute before serving. This brief resting time allows the flavors to settle and meld.
Serve warm and enjoy the delightful crunch of your Crispy Parmesan Asparagus!
