Step 1

Preheat your grill to 350 degrees, and spray a 13x9 aluminum baking pan with non-stick cooking spray.

Step 2

Mix all ingredients, except corn flakes and butter, together in a large bowl.

Step 3

Gently spoon it into the prepared baking pan.

Step 4

Melt the butter and mix it with the corn flakes. Sprinkle the cornflake mixture on top of the casserole.

Step 5

Grill at 350 degrees for 1 to 1 1/2 hours, or until potatoes are tender. If the top starts to brown too much, cover with foil until the potatoes have finished cooking.

Step 6

Remove and serve hot.
