The Stainless Steel Collection from Le Creuset is expertly crafted by European artisans for superior performance. The three layer construction features a full aluminum core bonded between stainless steel. The deep fry pan gives a bit more room for added ingredients in your dish and foods come out deliciously crispy and golden thanks to the tri-ply construction. The additional helper handle on the 11 and 12.5 provides extra stability and control.
