If you're cooking for a larger group or preparing large batches of food, a large or extra-large cast iron skillet is the best choice. These griddles offer plenty of room to cook multiple portions at once, making them perfect for dishes like stir-fries, burritos, and even deep-dish pizza. Large Cast Iron skillets and Extra Large Cast Iron Skillet size and ability to retain heat make them a great choice for outdoor cooking, whether on a grill or over an open fire.
