Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper or lightly grease it.
Wash the asparagus and snap or trim off the woody bottom ends.
Place the prepared asparagus on the baking sheet and drizzle evenly with olive oil.
Sprinkle the minced garlic, salt, pepper, and fresh thyme over the asparagus, tossing to coat the spears thoroughly.
In a small bowl, combine the grated Parmesan cheese and breadcrumbs, then sprinkle this mixture evenly over the asparagus.
Roast in the preheated oven for 10 to 15 minutes, or until the asparagus is tender and the breadcrumb topping is golden brown.
Remove from the oven and immediately drizzle with fresh lemon juice before serving.
