Tossing a variety of vegetables and some olive oil in a pan and cranking up the heat is one good way to roast them, but here we explore the wonderful possibilities of roasting vegetables individually. Sometimes this means much less work, and a much simpler dish—as in Oven-roasted Zucchini, which takes about 5 minutes of preparation time and 15 minutes of roasting. At the other end of the spectrum is a big production, but one in which each vegetable retains its unique flavor. We also offer simply roasted beets with creamy goat cheese, an assemblage of roasted vegetables from the onion family, and probably the best roasted bell peppers you’ve ever tasted.
