How to make scalloped potato casserole

Ingredients

There are only 4 ingredients. Yay!

Some shredded sharp cheddar cheese, sliced onions, cream of celery soup and the star of the show……

The potatoes. I peeled 3 potatoes but I only used two of them.

Yay for potatoes!

A little digression

One of my favorite things to eat when I was a little girl was mashed potatoes. Whenever I thought of them, I would see a bowl of fluffy whiteness in a blinding spotlight and hear trumpets blaring in the background!

At dinner, I would have more potatoes on my plate than anything else. I loved them. I still really like them, but I don’t eat them as much anymore. Just at holidays. Maybe it’s because I would eat them like I did when I was a kid and now, I not only like a more balanced meal but I like my waistline. 😉

Here’s another mashed potato story, but it’s not related to eating them. The girls of the family, (there were four of us), would have our after-dinner chores. Two of us would do the dishes and the other two would clear, put the food away and sweep the floor.

Well, this particular story has my sister Robyn washing the dishes, and little ole me drying. For a joke, Robyn put the dirty mashed potato pan directly in the drying rack and I, who was not paying attention, picked the pan up and swiped the inside with my dishtowel. Needless to say, the dishtowel was covered with potatoes. Did I eat some of the potatoes off of the towel? You will never know, because I’m not telling. 🙂

Okay! OKAY! I did!

Back to the scalloped potato casserole

I preheat the oven to 350 degrees Fahrenheit.

I cut the onion in half and slice both halves thinly. I put the slices in a big mixing bowl along with the cream of celery soup and the shredded cheddar. I take a rubber spatula and mix it all up.

Time to slice the potatoes.

I want them to be thinly sliced so I use my handy dandy food processor. This glorious machine has an exact slicing system that allows me to slice things super thin. That’s what I did this time. It seems every time I make these potatoes, I vary the thickness of the slices and I can’t say which thickness I like best: Super thin, sort of thin, a little thicker or thick.

I think I need more research. Yes. That’s it. I need more scalloped potatoes just so I can make a decision. It’s the only way!

I layer the bottom of a 8 x 8 baking dish with the sliced potatoes. Notice that I don’t layer the potatoes as thickly for this layer.

I then dollop and spread some of the onion mixture on top of those potatoes.

First layer done. Yay. As you can see, I don’t spare the onion mixture.

Next, I put a thicker layer of potatoes on top.

I continue alternating the onion mixture with the potatoes, ending with the onion mixture. I put 4 layers in this casserole until I reached the top.

I cover the dish with foil and it’s time to pop these potatoes in the oven.

After the casserole has been baking for a 1/2 hour, I uncover it and continue to bake them for another 1/2 hour. They will be bubbly and golden brown.

For best results, I let this casserole rest 20 to 30 minutes before cutting into it and serving.

Time to plate and eat this delish dish tout de suite.

Doesn’t that look good? It does to me! I’ve paired it with roast beef. YUM!
