Last year I froze the best broccoli we have ever raised. I did not blanch.
Did Not Blanch Frozen Broccoli

Blanching vegetables prior to freezing halts the enzyme action to prevent vegetables from degrading and becoming tough, thus preserving nutrional value. Freezing has the same effect as blanching. While everyone has differing views about blanching, you should know that you can still eat the broccoli without any issues. But it's stay in the freezer will be limited as opposed to those that are blanched. You will need to use the unblanched broccoli within 6 weeks (florets) to 3 months (stalks). Broccoli that has been blanched can remain in the freezer for up to 8 months.
