Broccolini looks a little like broccoli stretched out into slender stems with small florets at the top. You may also see it sold as tenderstem broccoli. It is useful because much of the stalk is edible and can cook quickly, but the leafy tops and thicker lower stems still need a little thought if you want an even result.
You can boil, steam, sauté or roast it. The best method depends on whether you're serving a simple vegetable side or want golden edges and garlic. The most important habit is checking the thickest stem, not just the soft floret.
Choose fresh bunches
Look for reasonably firm green stalks and tightly formed florets. Some flowering or purple varieties naturally look different, so use the specific produce label as your reference.
Avoid slimy spots, wet decay and a strong unpleasant smell. A slightly bent thin stem isn't necessarily spoiled, but very limp stalks may have lost freshness.
Keep broccolini refrigerated appropriately and use it soon. Delicate floret tops generally deteriorate faster than thick root vegetables.
Rinse and prepare the stems
Wash under running cold water, paying attention to the small flower heads where grit can collect. Shake or pat dry according to the method you plan to use.
Trim a little from the dry bottom of each stalk. Most tenderstem stems don't need peeling, but an unusually thick fibrous base can be pared or trimmed.
If several stems are much thicker than the rest, split those lengthways. That lets them cook at a similar pace without turning the thin tops to mush.
Boil for a quick side dish
Bring enough water to a steady boil and lower the prepared stems in carefully. Begin checking after a few minutes because thin stems cook rapidly.
Tenderstem broccoli can often be ready in roughly three to five minutes, depending on thickness and personal preference. The correct endpoint is a tender stem that still retains some bite.
Drain promptly rather than letting it sit in hot water. A quick squeeze of lemon and a little butter are often enough to finish it.
Steam to keep it delicate
Arrange the stems in a steamer basket above simmering water. Cover and steam until the thickest base yields when pierced with a knife.
Steaming gives you control without boiling the florets in a large volume of water. Avoid piling the bunch into a dense bundle where steam can't circulate evenly.
Take care lifting the lid. Serve promptly once the stems are tender, or move them into a cold-water bath if preparing a chilled salad.
Sauté in a wide frying pan
Heat a little oil and add broccolini in a single layer where practical. Let the stalks contact the pan so they develop light colour.
Add a tablespoon or two of water and cover briefly to soften thicker parts, then uncover to allow remaining liquid to evaporate.
Season near the end. Finely chopped garlic can burn rapidly, so add it once the vegetable is nearly ready rather than at the start of a long cooking period.
Roast for browned tips
Dry the washed stems well, toss with a light film of oil and place on a roomy baking tray. Roast in a moderately hot oven until the bases are tender and the tops begin to brown.
Check early, as the delicate florets can crisp before the thickest stalk has softened. Splitting chunky stems beforehand helps.
If the tips become dark too quickly, lower the heat or move the tray farther from an upper element rather than allowing them to burn.
What about grilling?
Broccolini can work well on a griddle or barbecue if you control heat and prevent thin stems from slipping through the grill.
A brief blanch beforehand helps especially thick stalks finish without burning the florets. Drain and dry well before applying oil.
Keep raw meat cooking areas and utensils separate from ready-to-eat vegetables, and use clean tongs to serve.
Seasonings that suit it
Lemon zest, garlic, black pepper and a little olive oil bring out the vegetable's mild flavour. Toasted almonds or sesame seeds add texture.
For an Asian-inspired side, a small amount of soy sauce and sesame oil can be appealing. Add salty sauces gradually so they don't overwhelm the greens.
A little grated hard cheese can finish roasted stems, though check dietary requirements if cooking for others.
Cook it in pasta
Boil or steam broccolini separately, then toss it with cooked pasta, olive oil and garlic. Alternatively add chopped stems to the pasta water near the end if the timings match.
If using whole stems, you may want to halve them for easier eating. Long stems can look attractive on the plate but be awkward to wind around a fork.
Don't cook the vegetable from the moment you add dried pasta. Most pasta needs much longer and will leave the broccolini overcooked.
Add it to a stir-fry
Cut thicker stalks diagonally so they cook rapidly. Add the dense stem portions before delicate florets if your bunch varies in thickness.
Work over appropriate heat with enough room in the pan. Too many vegetables at once release liquid and steam rather than browning.
A splash of sauce near the end gives flavour without leaving the pan full of watery liquid.
How to check the texture
Pierce the thickest stem with the tip of a knife. It should go in fairly easily for tender broccolini, with a little resistance if you like a firmer bite.
The florets may look cooked before the base is ready. If so, cover briefly to steam the lower stem or cut thick stalks more evenly next time.
If everything collapses when lifted, you've probably cooked it too long for a tender side dish, though it may still be fine in a soup.
Why it tastes bitter
Some broccoli-family vegetables naturally have a slight bitterness. Old produce and over-browned floret tips can emphasise it.
Try a fresher bunch, lighter roasting and a little lemon or oil to balance the flavour. Adding a mountain of sugar isn't necessary.
A strong burnt taste is not ordinary vegetable bitterness. Shorten the cooking or reduce the heat.
What about the leaves?
Small leaves attached to broccolini stems are usually edible. They may soften faster than the stalk and can be left on in ordinary cooking.
Inspect for yellowed or spoiled foliage and remove anything unsuitable. Don't confuse normal small leaves with extensive rotting material.
Keeping sound leaves saves preparation time and reduces waste.
Store cooked leftovers safely
Cool and refrigerate promptly in a clean covered container. Reheat thoroughly where appropriate and expect a softer texture after chilling.
Leftover stems can be chopped into omelettes, noodle dishes or soup. They are less likely to retain their just-cooked crunch.
A simple starting method
Trim dry ends, rinse, cook the thickest stems until tender and season lightly. For maximum speed, steam or boil; for richer flavour, sauté or roast.
Broccolini is forgiving once you stop treating its stems as though they all have the same thickness.
