Chopped broccoli weighs 91 grams per cup, and it belongs to the cruciferous vegetable family alongside cauliflower and cabbage — a real botanical grouping, not just a culinary one, and the source of the sulfur-containing compounds responsible for broccoli's characteristically stronger smell when it's overcooked.
That sulfur smell intensifying with cooking time is a genuine, well-documented chemical reaction, not just a matter of taste — the longer cruciferous vegetables like broccoli cook, the more those sulfur compounds break down and release, which is part of why many cooks specifically favor steaming or a quick sauté over prolonged boiling for broccoli, both to preserve texture and to limit that stronger smell and flavor from developing.
This site's freezing guidance for broccoli, like kale and spinach, specifically recommends blanching first — a quick boil followed by an ice bath halts the enzyme activity that would otherwise continue degrading broccoli's color, texture, and nutrients even at freezer temperatures, producing a noticeably better result than freezing it raw.
Broccoli's dense, irregular florets pack somewhat loosely into a measuring cup (91g/cup chopped), with real variation depending on how small the pieces are cut — finely chopped broccoli measures noticeably heavier per cup than large, roughly-cut florets, since smaller pieces settle into the gaps between larger ones the same way any chopped vegetable does.
Broccoli stems, often discarded, are actually just as edible as the florets once peeled of their tougher outer layer — chopped and cooked, they contribute meaningfully more usable vegetable per head than a recipe assuming florets-only would account for.
Steaming or quick-roasting broccoli preserves more of its texture and color than boiling, which tends to leach both flavor and nutrients into the water.
A quick blanch in boiling water followed by an ice bath keeps broccoli's bright green color if it's being served cold later.

Frequently asked questions
Why does overcooked broccoli smell stronger than fresh broccoli?
Broccoli belongs to the cruciferous vegetable family and contains sulfur compounds that break down and release more intensely the longer it cooks — a real chemical reaction, which is part of why quicker cooking methods like steaming are often favored over prolonged boiling.
Why does this site recommend blanching broccoli before freezing it?
Skipping that step leaves the florets' own enzymes still active in the freezer, slowly working against color, texture, and nutrient content the whole time the bag sits there — a brief dunk in boiling water followed immediately by an ice bath shuts that enzyme activity down before it can do that damage.
Are broccoli and cauliflower nutritionally similar?
They're both cruciferous vegetables and share some overlapping nutritional benefits (fiber, vitamin C, and various plant compounds), though they're not identical — broccoli generally carries somewhat more of certain nutrients like vitamin K, reflecting real differences even within the same vegetable family.
How long does chopped broccoli last in the fridge?
About 3-5 days in a sealed container — watching for yellowing florets (broccoli's early decline sign) and sliminess is more reliable than relying on a fixed number alone as that window closes.
Does broccoli stem weigh the same per cup as the florets when chopped?
Close enough for this site's practical conversion purposes — the stem is somewhat denser and less airy than the florets, but the difference isn't large enough to warrant a separate figure for a typical chopped mix of both parts.
