For roasted/baked broccoli, a good general rule is: 400–425°F (200–220°C) , for about 15–22 minutes , until the edges are browned and crisp and the stems are tender.

Here’s a quick guide:

  • If you want it softer and less browned: use 375–400°F (190–200°C) for 15–25 minutes.
  • For classic roasted broccoli (crisp edges, tender inside): use 400–425°F (200–220°C) for 15–22 minutes.
  • For very crispy, browned broccoli: use 425°F for 18–22 minutes , or up to 450°F for a shorter time, watching closely so it doesn’t burn (especially if using more oil or frozen broccoli).

Simple method:

  1. Preheat oven to 400–425°F (200–220°C).
  1. Cut broccoli into similar-size florets and dry them well so they crisp instead of steam.
  1. Toss with olive oil, salt, and pepper (plus garlic, lemon, or parmesan if you like).
  1. Spread in a single layer on a baking sheet—no crowding.
  1. Bake 15–22 minutes , tossing once halfway, until edges are golden brown and crisp.

If you tell me whether you’re using fresh or frozen broccoli and how crispy you like it, I can give you a more tailored time–temp combo.
