Ingredients

4 russet potatoes, (peeled and sliced into ¼-inch slices (about 2 pounds))
1 yellow onion, (sliced into rings)

Steps

Preheat oven to 400°F. Lightly spray an 8x8-inch casserole dish with nonstick cooking spray.
Arrange the potatoes and onions in the prepared baking dish, staggering potato and then onion.
In a medium-size saucepan, melt butter over medium heat. Mix in the flour and salt, and stir constantly with a whisk for one minute. Stir in milk. Cook until mixture has thickened.
Stir in cheese all at once, and continue stirring until melted and smooth, about 30-60 seconds.
Pour the cheese sauce over the potatoes, and cover the dish with aluminum foil.
Bake for 85-90 minutes, or until the potatoes are tender.
For a crisp topping, change the oven setting to broil after the potatoes are baked. Broil until golden brown.
Season with salt and pepper to taste and serve.

Great recipe! We have gluten allergies with two people in our family so I used GF flour, no one could tell. I’ve made this recipe before with regular flour and honestly it tasted the same. Delicious! Stacking the potatoes lets the cheese and sauce meld evenly together. I doubled the recipe so bake time was increased by about 30 minutes.

Yum! Thank you! I added a couple dollops of sour cream, great results. And I love the eye appeal in the stacking of the potatoes in the baking dish! I have never seen them done that way before, which surprised me! Thanks again for a delicious addition to our Christmas table. -Sheri Minnesota

We loved it! I added broccoli & celery, and cooked the onions before adding them. Just before cooking, I added a little bit of crunchy fried onions and more cheese. It was delicious!

My family loves these scalloped potatoes, and they’re hard to please. I need to now double the recipe. I’d like to do a 9x13 pan, but how long should I cook it?
