- 1 tablespoon butter
- 1 tablespoon olive oil
- 1 medium onion, diced
- 2 tablespoon all-purpose flour
- 1 ¾ cups skim milk
- ¼ cup heavy cream
- 2 cloves garlic
- 3 cups shredded cheddar cheese, divided
- ⅓ cup chives, snipped
- 1 teaspoon nutmeg
- 6 medium potatoes, thinly sliced
How to make these cheesy scalloped potatoes
Start by preheating the oven to 350ºF (180ºC). Melt the butter and olive oil in a medium saucepan over medium heat, then add the diced onion and cook until soft.

Stir in the garlic and cook another minute or so. Than stir in the flour and mix well. It will act as the base of a roux.

Add the milk, heavy cream and stir over medium heat until it began to bubble and thicken.

Remove it from the heat and mix in 2 cups of the grated cheese. I used a cheddar, mozzarella blend. Set aside.
It’s so easy to assemble this recipe for cheesy scalloped potatoes. First, spray a 9 x 13 inch baking dish with Pam butter spray.
Then begin layering the casserole with a single layer of potato slices, then the snipped chives, then some of the sauce.
Continue to layer until the potatoes are used and the sauce is gone.

Sprinkle the top with the remaining cup of cheese and another sprinkling of chives. Bake for 60 minutes until brown and bubbly.
If I am cooking if for a big crowd, such as for Thanksgiving or Christmas, I bake it 40 minutes the day before and then heat it for the last 20 minutes right before serving. This cuts down on the actual cooking I have to do on the holiday.

Serve immediately. This fall side dish recipe is great served hot or cold.

These potatoes have the most amazing taste. I have never taken them to any gathering when the plate is not completely empty by evenings end.

So in reality you slice the potatoes (slice/cut them all about the same size and thickness) ensuring that they all cook exactly or as close to the exact same time as you can get them, then once they’re all cook through, you place the cheese on the top only so the cheese starts to bubble and melt...

Hi Shunda. No, I don't cook the potatoes alone. I top them with the cheese as described in the recipe card in layers with the cheese on the top and cook the whole casserole at one time. Carol

What type of potatoes do you use?

Hi Wendy. Any types of potatoes work fine. I used russets since they are large and make it easier to complete the casserole by not having to peel too many. Carol

Have you ever made this recipe in the crockpot?

Hi Danielle. Sorry for the confusion. It's actually both. Some goes in during the cookie making stage and the some is used to dust them. I've adjusted the recipe card to reflect this. Carol

I want to make this on Sunday and serve it on Friday. Should I cook it completely and then freeze it? Or, prepare it and freeze it uncooked, defrost on Friday and then cook? Thanks!

Hi Michelle. Yes, I do this often. I cook the casserole for 40 minutes and then cover it and keep it in the fridge. The next day I remove, bring it to room temperature and finish baking (covered with foil) for about 20 minutes. Carol
