Snap or cut off the woody ends of the asparagus spears. Spread them on a large rimmed baking sheet, drizzle with olive oil, add the minced garlic, salt, pepper, and red pepper flakes, and toss until evenly coated.
02 -
Bake at 400°F (200°C) for 8-10 minutes until the asparagus is just beginning to soften and turn bright green. Thinner stalks may need only 6-8 minutes.
03 -
Remove the pan from the oven. Sprinkle mozzarella evenly over the asparagus, then dust with parmesan. Return to the oven and bake for another 5-7 minutes until the cheese is melted and bubbling.
04 -
Switch the oven to broil. Watch closely and broil for 1-2 minutes until the cheese is spotted golden brown. Remove immediately to avoid burning.

Squeeze fresh lemon over the top and serve straight from the pan while the cheese is still hot and stretchy.
