Do you want to create a pretty elegant looking potato dish that is pretty darn easy to make?  Then this Baked Potatoes and Onions is your dish.  All you need to pull this dish together is a mandolin.  You want to get a pretty thin slice on your potatoes and it would take a really long time if you were cutting these by hand.  Also, the slicing occurs before they potatoes are cooked at all so you need a strong tool to do the cutting.

I adapted the basic recipe from The Smitten Kitchen.  She only uses sweet potatoes.  I used a Idaho potato and added onions for additional sweetness and flavor.  The onion addition is a great idea.  I hand sliced the onions but a mandolin would have been a good idea.  Ask me why I cut these by hand and did not use my mandolin?  I have no good answer.  Why do we make extra work for ourselves when cooking?  You know what I am saying.  We all do it.  I do it all the time.  I never take the easy way out.  My mandolin was out so what was I thinking.

So I digress.  These Baked Potatoes and Onions are so simple to make.  Once the potatoes and onions are cut, they are added to a baking dish that has butter and oil at the base.  The potatoes are placed in the baking dish vertically – stand them up on their side.  Put onions in between every few potatoes.  The potatoes are arranged in a ring around the dish.  Pack them pretty closely.  When you can not fit any more potatoes in, top with the remaining onions.
