How to Cook Broccoli to Keep Its Nutrients

The best way to cook broccoli to keep its nutrients is to steam it for 3 to 5 minutes, or stir-fry it quickly, rather than boiling it for a long time. Broccoli is affordable, easy to prepare and one of the most popular vegetables in UK kitchens. How you cook it affects how much of its vitamin C ends up on your plate.

What broccoli gives you

Broccoli contains fibre, vitamin C and vitamin K. Vitamin C contributes to the normal function of the immune system, and vitamin K contributes to normal blood clotting and normal bones. An 80g portion, about 2 spears, counts as one of your 5 A Day, and its fibre helps you towards the NHS recommendation of 30g of fibre a day.

Why boiling loses more vitamin C

Vitamin C dissolves in water and breaks down with heat. When broccoli sits in boiling water, some of it leaches out into the water, which usually goes down the sink. The longer and hotter the cooking, the more is lost. That is why quick, low-water methods keep more of it.

Step 1: Prepare it

Wash the broccoli and cut it into even, medium-sized florets so they cook at the same speed. Don't throw away the stalk: peel the tough outer layer, slice it and cook it with the florets. Some people chop broccoli a few minutes before cooking it. Lab research suggests this may help preserve some of its natural plant compounds, but it is a small extra, not a must.

Step 2: Choose a gentle cooking method

• Steaming: 3 to 5 minutes, until the broccoli is tender but still bright green. This is one of the best ways to keep its vitamin C.
• Stir-frying: a few minutes over a medium heat with a little olive oil. Good on busy days.
• Microwaving: in a covered bowl with a splash of water for 2 to 3 minutes, which uses very little water.
• If you boil it: use only a little water, keep it short, and use the cooking water in a soup or sauce.

Step 3: Serve it simply

A drizzle of olive oil, a squeeze of lemon, garlic or a few toasted seeds is all it needs. Food you enjoy is food you keep eating, which matters more than any single cooking trick.

Raw or cooked?

Raw broccoli keeps all its vitamin C, but some people find it harder to digest. Lightly cooked broccoli is often easier on the stomach and still nutritious. Having a mix of both is a sensible, flexible approach.

The takeaway

Healthy cooking does not need to be complicated. Small choices, like steaming instead of boiling and eating the stalk, add up over time.
