Broccoli converter: whole broccoli heads, cups, grams

A recipe says '2 cups chopped broccoli' but you have a couple of whole heads on the counter. A medium head weighs about 450 g whole including the stalk, so the count shifts as head size changes. This converter moves between whole broccoli heads, chopped cups, grams, and ounces.

A small head is about 40% of the weight of a large one, so 'two heads' in a stir-fry can swing the yield a lot. Pick the right size below to keep roasts, soups, and pasta on target.

Broccoli varieties and best uses

The conversions above are the same whatever variety you use; the difference is what each is good for. Here is how the common broccoli varieties compare.

VarietyBest for
CalabreseEveryday roasting, steaming, and stir-fries: sturdy green florets on a thick stalk, the standard supermarket head.
Tenderstem (Broccolini)Quick sauté and steaming: a kai-lan and broccoli hybrid with long thin stalks that cook in minutes and stay sweet.
Sprouting broccoli (purple or white)Spring side dishes and pasta: tender slim stems and small florets, steam or quick-roast.
RomanescoRoasting and showpiece sides: lime-green fractal florets with a mild nutty flavour that holds shape.
Chinese broccoli (Gai lan)Wok dishes and oyster-sauce sides: leafy stems with small florets, blanch then stir-fry.

Which should I pick?

For everyday roasting, steaming, and stir-fries, Calabrese is the default supermarket pick. No Calabrese? Tenderstem (Broccolini) cooks faster with sweet, tender stems. For roasting that holds its shape with a nutty edge, choose Romanesco. For Asian stir-fries, Chinese broccoli (Gai lan) brings leafy bite to wok dishes.

Frequently Asked Questions

What is the size of a medium broccoli head?
A medium broccoli head weighs about 450 g, which works out to roughly 4.74 cups (4.95 US cups) of chopped flesh. Broccoli heads come in a range of sizes depending on the season, variety and where they were grown, so weight and cup figures shift accordingly. Use the size selector above to match what you actually have, then read the exact conversion for any amount.
How much does a medium broccoli head weigh?
A medium broccoli head weighs about 450 g, with a small one around 280 g and a large one near 700 g. That range changes the weight of any recipe that counts broccoli heads by the piece, so set the size selector to match what you actually have before trusting a cup or gram figure.
How much does an average broccoli head weigh?
An average broccoli head is the same as a medium one: about 450 g. A small broccoli head is lighter at around 280 g and a large one heavier at about 700 g, so the size you actually have changes the total for any recipe that counts broccoli heads by the piece rather than by weight.
How much does a large broccoli head weigh?
A large broccoli head weighs about 700 g, noticeably more than a medium, or average, one at 450 g or a small one at 280 g. Set the size selector to large to convert cups, grams and ounces for the bigger broccoli heads you actually have on the counter.
How do I convert grams to ounces for any ingredient?
Converting grams to ounces is pure weight maths that applies to any food, not just broccoli heads, so 500 grams is always 17.64 ounces. For other amounts, the weight converter at the link below handles grams, ounces, pounds, kilograms and stone in both directions. Grams to ounces converter
