Cook the pheasants by frying, boiling or slow cook in a crockpot. Cooking in the crockpot or boiling will make the meat tenderer.
Cool. Remove meat from bones and chop into bite sizes pieces.
Spray a 9 x 13 casserole dish with non-stick spray. Layer in the meat, potatoes and onion.
In a mixing bowl, mix the milk and flour. Season to taste with salt and pepper. Pour over the top of the casserole. Top with butter in 3 places.
Bake at 350 degrees for 30 – 45 minutes or until the casserole thickens and gets light brown on top.
Serve and enjoy.
