👨🍳 Chefy Tip: Grate the parmesan yourself — pre-grated has anti-caking agents that kill browning. Toss asparagus with the dry ingredients separately from the oil, then combine both at once. That triple-layer coating sticks where you want it.
Preheat oven to 425°F. Line a baking sheet and place it in the oven to preheat.
Toss asparagus with olive oil, salt, and pepper until evenly coated.
Mix parmesan and breadcrumbs. Press mixture onto asparagus spears to coat.
Arrange in a single layer on hot baking sheet. Roast 12–15 minutes until golden and crisp.
Serve immediately with lemon wedges.
Water must evaporate from a vegetable's surface before browning can occur — which is why a preheated pan and single-layer spacing are essential for crispiness. Parmesan contains free glutamates from the aging process that directly activate umami taste receptors.
