Roasting tenderstem broccoli couldn't be easier. Simply wash and pat dry and then place on a baking tray, drizzle with oil and season well. Roll it around a little in the oil so it's lightly coated and place in the middle of a preheated oven (200C / 400F) for 10-12 minutes depending on how cooked you like it (10 minutes should be enough for al dente - for a standard sized piece).
