  • 16 ounces frozen broccoli florets
  • 1 1/2 tablespoons olive oil
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon garlic powder


  • Preheat oven to 450℉ and line a large baking sheet with parchment paper or a silicone baking mat.
  • Place frozen broccoli florets on the baking sheet. Spread them out so the florets have lots of space. Crowding the florets will result in steaming instead of roasting, so give 'em their space! If you need to, divide the florets between two baking sheets.
  • Roast for 10 minutes. Roasting the frozen broccoli prior to adding oil and seasoning allows the water to cook off first.
  • After 10 minutes, drizzle with oil and season with salt and garlic powder. Use tongs to toss the broccoli.
  • Return the broccoli to oven and cook for 8-10 more minutes depending on the size of your florets (see notes) or until the ends of the broccoli are starting to turn golden brown.


  • Consider the size of your florets. Frozen broccoli florets come in many different sizes and some are cut smaller than others. If your broccoli florets are quite small, you will probably only need to roast them for 3-5 minutes after seasoning with oil and salt. Just keep a close eye on them so you don't end up with burned broccoli.
  • Don't skip the dry roast. This helps to cook off the high water content in the frozen broccoli before adding the seasoning.
  • Don't crowd your florets on the baking sheet. Crowding them will result in your florets steaming versus roasting. If you don't have a big enough baking sheet, use two baking sheets instead of one.
