This is my favorite cooking method if intending to enjoy as a side dish. While the broccoli won't get as crispy as roasted fresh broccoli, they will still have a nice bite to them and you can flavor just the same!
While many recommend thawing the broccoli first, I've found this method to be easier and produces the most optimal texture.
Can also be Steamed and Microwaved.
Frozen broccoli works great in soups, casseroles, and any recipe that requires it to be soft!
