A super easy way to make them is to slice 4-5 potoatoes very thin and chop an onion very fine. Make a layer of potatoes in the bottom of a casserole dish, then a layer of onions, then srpikle some parm cheese and shredded cheddar. Keep layering that way until you are out of ingredients and then pour about a cup of heavy cream over the top. Bake at 375 for an hour covered and then uncover and bake another 15 minutes.They are SOOO delicious and very simple.
