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.
- 3 Pounds Idaho potatoes
- 1 large yellow onions
- 3 tablespoons butter, melted and divided
- 3 tablespoons olive oil,divided
- 2 teaspoons salt
- 2 teaspoons pepper
- Begin by peeling and washing the potatoes.
- Using your mandolin, slice all the potatoes to roughly 1/4" of thickness
- Slice the onions to a similar thickness.
- In a baking dish, place 2 tablespoons each of the butter and oil.
- Start ringing the potatoes and onions around the outside of the bowl.
- After every three potatoes, add a sliced onions layer.
- Work all the way around until a circle is created around the outside of the dish.
- Move to the center and try to create a ring again following the same potatoes and onion distribution.
- Taking a brush, brush the remaining butter and oil on the top of the potatoes and onions.
- Sprinkle the salt and pepper evenly on the top of the potatoes.
- Bake in an oven at 450 degrees for approximately 50 minutes.
- Serve and enjoy!
