Never-Fail Scalloped Potatoes Tips

How do you thicken scalloped potatoes?

    IN CANADA, SCALLOPED POTATOES HAVE CHEESE. This is my usual recipe. Sometimes, they take longer than the recipe recommends.

    Did anyone notice there were NO Onions in the Ingredients section. So how many onions, and I presume sliced?

    I will not give any scores yet, but I do anticipate giving a high rating. These potatoes are in the oven right now and I can’t wait to taste them. I used very thinly sliced Potatoes and onions, and I think that will be delicious. I made the sauce but did not measure the cheese so it became a little too thick. I thinned it down, and think possibilities of adding spices/bacon/whatever you want are endless. I will not join in the debate of scalloped versus au gratin, , it’s whatever you like!

    This is my go to recipe everytime I'm wanting a break from mashed potatoes. I love them!!! My shortcut is that I parboil the potatoes before assembling the dish. Cuts down on baking time and the potatoes turn out perfect everytime!

    I will end this right now...I googled 'Traditional/old fashioned Scallop Potatoes'....NO CHEESE! FACTS are a strange thing. Just thought I'd share this info with everyone.
