Originally designed to meet the demands of professional chefs, All-Clad continues to be the undisputed choice in four-star kitchens throughout the world. The cookware has exquisite lines, impeccable balance, meticulous hand-finishing, and superior heat-conductivity. Stainless with d5 technology, the latest line from All-Clad, now delivers unprecedented evenness of heat for uniform browning. This cookware boasts five layers of metal (alternating bands of aluminum and stainless steel) — this construction not only heats more evenly, but more quickly and retains heat longer to make the cookware more energy efficient, and more durable. There are two aluminum layers, one to conduct and one to sustain heat. The stainless-steel core diffuses heat and delivers consistent results. The stainless interior is stick-resistant and cleans easily. The magnetic stainless steel exterior has a polished finish and can be safely used on conventional gas and electric ranges, as well as on induction cooktops. The flared rim of the cookware is designed for easy, dripless pouring. This line also features newly-designed ergonomic handles that offer superb handling comfort and control. The casserole is just the right size and shape for blanching vegetables, cooking beans or rice, or preparing large quantities of oatmeal, pasta, chili, or chowder. The casserole comes with a BONUS steamer insert.
