How to Cut Broccoli into Florets (Without the Green Confetti)

Should you cut from the top or the underside of the broccoli head?

Always the underside. This is the one rule that separates a clean board from a green mess.

When you cut from the top, your knife goes straight through the floret buds. Those tiny green flower heads shatter. You get a pile of mismatched pieces and broccoli dust that sticks to everything.

From the underside, you can see exactly where each stem attaches to the central stalk. That is your cutting guide. Score the stem with the tip of your knife, then use your hands to pull the floret apart at the natural seam. I call this the pull-apart method and it is the only one I use now. The florets come off looking like little trees, not stumps. The board stays clean. Adam stopped picking through his dinner.

Step-by-step: How to cut broccoli into florets

Here is what I do every time. About two minutes once you have done it twice.

1. 1
   Sharpen your knife first. A dull knife crushes the buds. Sharp blade, clean cuts. Most guides skip this.
2. 2
   Set the crown upside down on the board. Stalk facing up. Now you can see where everything branches.
3. 3
   Pick off any leaves by hand. They come off cleanly with fingers. The leaves are edible in soups or salads.
4. 4
   Start at the outermost florets. Find where each stem branches from the central stalk. Run the knife tip into the stem halfway, then pull the floret apart with your hands at the natural seam.
5. 5
   Work inward, repeat. Once the outer florets are off, the remaining clusters are easy to see and reach.
6. 6
   Split any large florets again. Same method: score the stem, pull apart. Cutting through the green top is never the answer.

One head gives you roughly 2 to 3 cups of florets.

What size should broccoli florets be for roasting?

This depends on what you are cooking, and getting it wrong is the main reason broccoli comes out unevenly done.

The real rule: uniform size within a batch. Even size means even cooking. That is genuinely the only thing that matters here.

Is the broccoli stalk edible?

Yes. And if you have been throwing it away, I did too for years.

The outer skin is tough and fibrous. That is what puts people off. Once you peel it, the interior is pale green, tender, and mild. Alfi actually prefers it to the florets. He calls the coins I slice from the peeled stalk “broccoli wheels.”

The stalk makes up roughly a third of the head by weight, with the same nutrient profile as the florets. (USDA FDC 170379) Throwing it away wastes a third of what you paid for.

Does cutting broccoli affect its nutrients?

Yes, and it is a bigger deal than most people realize.

Broccoli contains glucoraphanin, which converts into sulforaphane when the plant cells are broken open. The conversion happens because cutting activates an enzyme called myrosinase. (USDA FDC 170379; Fahey et al., 1997)

Heat above 70 degrees Celsius destroys myrosinase. Chop and cook immediately, and very little sulforaphane forms. But chop and wait 40 minutes before cooking, and myrosinase finishes its work first. (Rungapamestry et al., 2007, British Journal of Nutrition)

Raw broccoli has 89.2 mg of vitamin C per 100g, nearly your full daily value. (USDA FDC 170379) Boiling strips roughly half of it. Steam or stir fry for a short time to keep more intact.

Should you wash broccoli before or after cutting?

After. This one surprised me.

Once the broccoli is cut into florets, you have much more exposed surface area to clean. Water reaches more of the plant. The florets get cleaner with less effort.

If you wash a whole head first, water gets trapped between the buds and makes the surface slippery when you are trying to cut. It also makes the board wet, which is exactly the wrong condition for a clean pull-apart.
