This scalloped potato casserole recipe is pure comfort food for my family. We would have this casserole at holidays and sometimes if we were lucky, Sunday dinner.

Why is this scalloped potato casserole recipe so comforting? Well, since I’ve been eating it forever, it evokes fond memories of holidays, Sunday dinners, company and visits with relatives.
Other than the occasional Sunday, I don’t remember having this potato casserole on just a normal, non-holiday day.
But why since it’s so delicious? Maybe because it wouldn’t be as special but truthfully I can’t imagine me ever getting tired of this side dish.
Ever.

Helpful tips
- I use a food processor because the one I own has an exact slice system. If you rather use a mandolin, go for it.
- My family made this in a 12 x 13 inch pan, but it’s just myself and hubby so I half the recipe. If you want to double the recipe, the recipe has a slider at the top that allows you to adjust the servings. 🙂
How to make scalloped potato casserole
Pre-step
Get a 8 x 8 inch pan.
Step one
Gather the ingredients – shredded sharp cheddar cheese, cans of cream of celery soup, onion and . . .
Step two
Potatoes. Even though you see three potatoes, I only used two.
Step three
Preheat the oven to 350 degrees Fahrenheit.
Step four
Peel and cut the onion in half and slice both halves thinly.
Step five
Place the onions in a big mixing bowl. Add the soup and cheese and mix it all together with a rubber spatula.
Step six
Time to slice the potatoes.
Since my food processor has an exact slicing system, I slice the potatoes thinly. But you can slice them to â…› inch thick.
Any thickness is fine but I like the thinly sliced potatoes.
Step seven
Place a layer of the sliced potatoes in the bottom of the baking dish. Notice I don’t layer the potatoes as thickly for this layer.
Step eight
Dollop and spread some of the onion mixture on top of the potatoes. As you can see I don’t spare the mixture.
Step nine
Place a thicker layer of potatoes on top.
Step ten
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.
Step eleven
Cover the dish with foil and bake for ½ hour. Uncover and continue to bake for another ½ hour.
They will be bubbly and golden brown.
For the best results, let the casserole rest 20 – 30 minutes before cutting into it and serving.
Time to plate and eat this dish tout de suite.
Let’s serve it.
Doesn’t that look good? It does to me! I’ve paired it with roast beef. YUM!
I hope you enjoyed this scalloped potato casserole recipe.
