Ingredients

Method

Preheat the oven to 400°F/200°C/gas 6. Peel and cut the vegetables into equal sized pieces, about 1-in/2.5-cm chunks. Toss vegetables and onions in olive oil in a large bowl and season generously with salt and pepper.

Spread the pieces out in a single layer on one or two roasting pans/trays so that the vegetables don't touch. Roast until the veggies are lightly browned and just tender, 45 minutes to 1 hour, depending on the vegetable. Remove and toss with additional olive oil. Season with salt and pepper and garnish with parsley before serving.
