I just recently came across this tip, but have already used it numerous times:

When you have a baked casserole that needs to be covered with foil, and you've filled the dish so full that the foil touches the food, just grease the inside of the foil before you put it on the dish. This is especially handy for dishes with cheese or tomato sauce (acidic) on top.

I usually do my greasing with butter, though you can use oil, shortening, or cooking spray if you want. I use butter because it's fairly healthy and won't leave marks on my pans. :)
