Offering maximum efficiency through modern technology, the d5 line from All-Clad bonds five distinct layers for superior cooking performance. The cookware features a patented, three-layer aluminum and steel core that directs heat sideways, eliminating hot spots and driving heat through the entire pan, not just the base. The non-reactive stainless steel interior offers the optimal cooking surface, and the brushed exterior layer resists warping. Topped with a tight-fitting lid to trap heat, this frying pan ably sears, sautes, braises and fries. Flared sides pour easily, and the stainless steel handles stay cool and comfortable as you cook.All-Clad has been crafting cookware since 1971.Need help choosing? View our All-Clad comparison chart.
