Easy Cheesy Scalloped Potatoes are a delicious potato dish, made with thin slices of potatoes, onions and a creamy cheese sauce.
Let me tell you a story about scalloped potatoes. About a decade ago, I decided that I was going to make them for Easter dinner, even though I had never made them before. I rarely ever listen that advice of don't make something for guests if you haven't made it at least three times before. I've never had any issue so I thought nothing of it.
The night took a bad turn when my thumb got into a disagreement with the mandoline but I soldiered on, finished the recipe, baked it and cooled it. I noticed the potatoes were still a little firm, but figured if I cooked it longer the next day it would be fine. That was a lie.
I checked the potatoes every 20 minutes the next day and they never softened. I tossed the entire contents of the casserole dish and the mandoline into the trash can and vowed I'd never make scalloped potatoes again. Clearly, I don't do a good job of listening to myself.
What are easy cheesy scalloped potatoes?
Scalloped potatoes are thinly sliced potatoes that are baked in a casserole dish. Between layers of the potatoes there is a creamy, cheese sauce made with butter, onions, flour, milk, chicken broth and cheese.

FAQ's for this recipe
- How thin do you cut the potatoes? As thin as you can, preferable between ⅛ and ¼ inch. Many people use a mandoline. I won't do that again.
- What is the difference between scalloped potatoes and potatoes au gratin? Scalloped potatoes doesn't always have cheese in the sauce and au gratin does. Potatoes au gratin are usually topped with bread crumbs before baking.
- Can you make scalloped potatoes in advance? Yes! Prepare the casserole, bake it and then cool completely before refrigerating. Let sit on the counter for 20-30 minutes before heating through for 20-30 minutes at 350.
- Why do you soak the potatoes? Potatoes contain starch and cooking potatoes that are too starchy will result in gummy potatoes that don't cook well.
- Why should I listen to you if you messed it up the first time? Everyone makes mistakes. I learned what likely caused the potatoes to be hard (not high enough heat) and realized that I'd never take the chance on being defeated by a mandoline again. 🙂
