Broccoli usually takes 15 to 25 minutes at 400°F , depending on how big the florets are and how crisp you want them. A very common sweet spot is about 20 minutes for tender broccoli with browned edges.

Quick Scoop

  • 15 to 18 minutes : brighter, firmer broccoli.
  • 20 minutes : most reliable all-purpose timing.
  • 22 to 25 minutes : deeper browning and crispier edges.

Best Result

For the best texture, toss the broccoli with a little oil, salt, and pepper, then spread it in a single layer on a baking sheet. Flipping or stirring halfway through helps it cook evenly.

Simple Rule

If you want:

  • Tender-crisp broccoli : start checking at 15 minutes.
  • Crispier broccoli : aim for 20 to 22 minutes.
  • Bigger florets : expect closer to 25 minutes.
