Once, the only roasted vegetables most people made were potatoes, either nestled next to a chicken, set in a pan under a rack holding a leg of lamb (as the French do), or scattered around a hefty rib roast.

Then came along other roasted vegetables, like red peppers served as an antipasto with fresh mozzarella or anchovies. Called "roasted," they were packaged already charred over a gas flame or under the broiler, but some smart cooks discovered how to do it themselves, in a blistering hot oven. Finally, in the 1990s, many chefs got into pizza-making and wood-burning ovens, and began roasting other vegetables, from asparagus to zucchini. At the same time, Roasting, A Simple Art, by Barbara Kafka, taught home cooks how to roast them, with irresistible results.

This roasting revolution is one of the best things to happen to the American diet. If you or your family have the same difficulty as most people getting a healthful amount of a wide variety of vegetables, just turn on the oven. From tots to the big guys who only want meat and potatoes, everyone goes for roasted vegetables.

Roasting vegetables achieves two things. By evaporating moisture, it concentrates their flavor. And high heat (at least 400 degrees) caramelizes the natural sugars in vegetables, producing a sweeter flavor, always an appealing feature to those with a sweet tooth. This technique is also a simple, efficient way of cooking.

Coating vegetables with oil before roasting is essential. A minimal amount, using a spray oil or rubbing it on with your hands, is sufficient. Without it, even tomatoes and other moist vegetables will dry out and shrivel rather than turn tender and succulent.
