My Mum used to make rabbit pie. It had white gravy and sliced potato and with a pastry top. I don't know how she made it though - it would have been an old Devon recipe from my Gran.
I'm not fond of rabbit. But the best way is casserole or stew, with potatoes, carrots leeks and/or onions, garlic and any other root veg you like, use some red wine or beer in the sauce.
