1You will need a big baking dish for a larger family two of them. Set your oven at 400 degress. Then wash your potatoes really well and set them aside. I recommend Irish Red potatoes for this recipe. Take your baking pan or pans and coat the bottom with the butter spray really well. Then sprinkle the parsley flakes over top of the butter spray. Slice your potatoes in half and place the white sides down till the pan is full. Then place in oven and let them cook for about 20 to 25 min. till done. This goes well with Oven Baked Chicken or any other main dish.
