All-Clad 3013 Hard Anodized Aluminum Nonstick Double Burner Grande 13-Inch X 20-Inch Grille Pan1 Recommendations
This grill pan measuring 13" x 20" is one of the biggest grill pans in the market; its extra-large size makes it ideal for cooking for large groups. It is made of hard-anodized aluminum, which makes it rust and scratch resistant.
Con It's supposed to cover two burners at the same time
Since it's so big, it is expected that you put this pan over two burners simultaneously, otherwise one half will remain cold. This is fine if you're cooking for a group but not always convenient if you're not planning to do a lot of grilling.
