Not many recipes for opossum, but here is one for the adventurous spirits out there. Just ran across this recipe, I have not made it. If you try it and like it, please let me know---does possum taste like chicken?
Wash the possum, trim off any excess fat. Season cavity with salt and pepper. Close with skewers, tie legs together. Scrub sweet potatoes, but do not peel. Place possum and potatoes in shallow roasting pan. Add water. Brush meat and potatoes with melted butter. Sprinkle with salt and cayenne pepper. Cover and bake at 350 degrees till meat and potatoes are tender, approximately 1 1/4 hours, Basting occasionally with melted butter. Uncover and bake until brown abut another 15 minutes or so.
