Wash asparagus and trim any tough ends off, leaving the tender part of the stalk. Transfer to baking sheet and drizzle with olive oil and lightly salt and peper.
Bake for 15-17 minutes, until asparagusis tender. Remove from oven and sprinkle mozzarella and parmesan cheese over asparagus, then return to oven for 2-3 minutes to melt the cheese.
While asparagus is baking, prepare panko breadcrumbs by heating a skillet over medium heat with butter. Pour in breadcrumbs and toast crumbs, stirring occasionally for 5-7 minutes until browned evenly. Add in garlic powder and lemon juice, cooking for 1-2 more minutes to crisp up.
Sprinkle lemony breadcrumbs over the roasted cheesy asparagus, then sprinkle lemon zest over breadcrumbs last. Serve warm.
Notes
Best served fresh. Can be refrigerated in an airtight container for up to 3 days, and warm up in the oven to make breadcrumbs crispy again.
