Can You Freeze Chopped Broccoli?
Yes, you can freeze it.
10-12 months (blanch first)
Broccoli's florets and stems don't decline at quite the same rate in the freezer, which is worth knowing if you're separating the two before freezing — the denser stem pieces hold their texture a bit better through a freeze-thaw cycle than the more delicate florets do, so a bag of mixed pieces will have some parts noticeably softer than others once thawed. The blanching step matters more for broccoli's color than almost any other vegetable on this site, since unblanched frozen broccoli tends to dull from bright green to a duller olive tone over time in a way blanched broccoli mostly avoids. Frozen broccoli steams or stir-fries well straight from frozen without needing to thaw first.
Spreading chopped broccoli in a genuinely single layer on the tray, not a crowded one, before that initial flash-freeze matters more here than for a smaller-cut vegetable, since broccoli's florets and stem pieces vary enough in size that crowded pieces easily stick together into small clumps even during that supposedly loose freezing stage.
Broccolini and standard broccoli crowns need slightly different blanching times before freezing, given broccolini's thinner stalks — treating the two interchangeably risks under-blanching broccolini's more delicate stems or over-blanching standard broccoli's denser ones, so it's worth adjusting blanch time by which variety is actually being frozen.
Broccoli florets frozen separately from stems, rather than mixed, let a cook use just the florets for a quick stir-fry while saving the denser stem pieces for a soup where their sturdier texture and longer cook time are less of a mismatch.
