Cooking food directly on oven rack Is it common to cook food directly on the oven racks?  I often do this (with a container for drippings) and was wondering if this is common or if there is a better solution.  It has worked out fine for me, but sometimes replacing these racks can be costly.  I do not replace them often, and they are not very hard to clean, but I would like to get some ideas on if I am doing this wrong.
Presumably the reason you're cooking directly on the oven rack is to let the fat drip down.  If so, do yourself a favour and get yourself a roasting rack.  It's an inexpensive piece of equipment that you place in a baking pan or on a cookie sheet; the food cooks on the rack and the pan/sheet catches all the drippings.  Way better than trying to replace an entire oven rack.

And if you really hate cleanup, you can line the pan with parchment paper or aluminum foil and just throw the rack in the dishwasher when you're done.
