Roast asparagus at high heat for about 8–15 minutes, depending mainly on how thick the spears are and how tender you like them.

Quick Scoop

  • Best oven temp: 425°F is the sweet spot for most “perfect roasted asparagus” recipes, giving a crisp-tender texture and light browning.
  • Thin spears: 8–10 minutes at 425°F, start checking at 7–8 minutes so they don’t overcook.
  • Medium spears: about 10–14 minutes at 425°F, fork-tender but not limp.
  • Very thick spears: 15–20 minutes at 425°F, checking from around 12 minutes onward so they don’t dry out.
  • Visual doneness cues: bright green color, tips just starting to crisp, and a fork slides in easily but stalks still hold their shape (not floppy).

Simple step-by-step

  1. Preheat oven to 425°F and line a baking sheet (optional but helps cleanup).
  1. Trim off the woody ends of the asparagus (snap or cut 1–2 inches from the bottom).
  1. Toss spears with olive oil, salt, and pepper, then spread in a single layer so most spears touch the pan for better browning.
  1. Roast:
    • Thin: 8–10 minutes
    • Medium: 10–14 minutes
    • Thick: 15–20 minutes, checking early
      (They’ll keep cooking a bit after coming out of the oven, so pull them when they’re just shy of your ideal).
  1. Finish with lemon juice, grated Parmesan, or garlic if you like, then serve right away.

A quick example

If you grab typical grocery-store asparagus in February 2026 and the stalks are pencil-thin, roasting them at 425°F for about 9 minutes will usually give you tender, slightly crisp spears—great with salmon or chicken on a weeknight.
