A Paella pan is very helpful when making Paella, but If you don't have a paella pan, use a 13- 15 inch or larger skillet. Try to find a heat source that can accommodate the whole paella pan or skillet. Depending on the configuration of your burners, you'll need to place the pan over two burners or set it on your largest burner. Either way, you'll have to move and rotate the pan to distribute the heat.
