These are my hubby's absolute favorite cheese potatoes! And I love them because not only are they delicious, but so easy to throw together! Especially handy when you have a lot of other things to make or grill. They stay piping hot for quite some time after they're done, so when you are grilling out, they can just rest, covered, no problem at all! Hope you enjoy, too!

In medium-sized bowl, mix sauce ingredients with whisk. Set aside. Halve onion half and slice thinly, set aside. Rinse potatoes and slice 1/4" thick. Spray a 2 1/2 qt. round casserole dish (with lid) with butter-flavored cooking spray. Spoon several spoonfuls of sauce onto bottom of dish to cover nicely. Layer, overlapping, slices of potatoes. (Half of them). Spoon half of remaining sauce over evenly. Top with half of sliced onions. Top with 1 cup cheese. (*I never measure, I just reach in and cover heavily. About 3/4" thick. We like a LOT of cheese!) Repeat with a second layer. Top second layer of cheese with dots of butter. Sprinkle top lightly with paprika and parsley. Bake in 375 degree oven, covered, for 1 hour. Remove lid, turn oven down to 350, and bake 15 minutes longer. It will bubble a lot, but it's ok. Any excess water from the cheese and or butter will evaporate. Remove from oven. *If there are any unwanted pools of oil from the cheese, dip a folded corner of paper towel carefully into the oil to absorb and remove. Cover and let rest for at least 15 minutes. Can stay pretty hot for at least a half an hour.
