Here is a recipe I got from my friend. Her sister Lindsey from Marysville, Ohio makes them and she says they are heavenly...
Best Scalloped Potatoes
Bake 5 pounds Yukon Gold potatoes in foil, wrapped individually, 400 for about 45 min. Leave in foil and let cool completely. Cut in Squares
3# block Velveeta cheese cut in small blocks
2 Large Vadalia Onions Chopped fine
1 pound bacon fried and crumbled.
1 Qt. Hellman's Mayo
Mix all ingredients together and let set in fridge overnight.
Bake at 350 until hot and bubbly and cheese is all melted.
I have my potatoes baked and are cooling in fridge. I'm putting it together Thur eve for our cookout Friday evening. I'll let you know how they turn out.
