Roasted Asparagus Recipe

Preheat oven

Preheat the oven to 425°F (220°C). Position a rack in the center of the oven.

Wash asparagus under cold running water to remove any grit. Pat dry thoroughly with a kitchen towel or paper towels. Trim the woody ends: hold a spear and bend until it snaps, then line up the rest and cut at that length (or trim about 1 to 1.5 inches from the bottom).

Place trimmed asparagus on a rimmed baking sheet in a single layer, tips pointing the same direction for even roasting. If spears are very thick, slice them lengthwise in half to ensure even cooking.

Drizzle the 2 tbsp olive oil evenly over the asparagus. Sprinkle 1 tsp kosher salt and 1 tsp freshly ground black pepper over the spears. Toss gently with your hands or tongs so each spear is lightly coated. Arrange spears again in a single layer without overlapping.

Zest the lemon directly over the asparagus to capture aromatic oils, then squeeze 1 tbsp lemon juice evenly over the spears.

Place the baking sheet in the preheated oven and roast for 10–14 minutes, depending on thickness: thin spears 8–10 minutes (tender-crisp), medium 10–12 minutes, thick 12–14 minutes (tender with slight browning). Halfway through (at about 6–7 minutes for medium), shake the pan or turn spears with tongs for even browning.

Remove asparagus from the oven when tips are slightly browned and spears are tender. Transfer to a serving platter.

While still hot, sprinkle 2 tbsp grated Parmesan over the asparagus if using. Add a pinch (or up to 1 tsp) red pepper flakes for heat if desired. Taste and adjust seasoning with a light additional pinch of salt or a squeeze of lemon if needed.

Serve immediately as a side dish. Leftovers keep in an airtight container in the refrigerator for up to 3 days; reheat briefly in a 400°F (200°C) oven for 5–7 minutes to refresh.
