From LifeHacker: Use a Bundt Pan as a Vertical Roaster [Kitchen Hacks]

Use a Bundt Pan as a Vertical Roaster [Kitchen Hacks]:
If you need to roast a turkey, chicken, or other meat and don't happen to have a roasting pan on hand Real Simple magazine's weblog shares that you can get the same roasting effect from a bundt cake pan. The cone in the center of the pan will keep the meat from touching the base and provide the same cooking effect.
All you need to is layer your root vegetables on the bottom of the pan, season your meat, and place the meat in the cavity over the center hole. You'll want to place a cookie sheet or large piece of aluminum foil underneath to catch the drippings and roast according to your normal instructions.
