So when it comes to the holidays or any kind of gathering you simply can't go wrong with a pan of Scalloped Potatoes.
But then cover them in a cheesy sauce with onions and garlic and it's pure perfection.
Seriously one of my favorite recipes which is why it's getting a much needed remake today...
So I could share updated information and tips on how to make these easy cheesy scalloped potatoes... along with some updated photos as well.
How to make cheesy scalloped potatoes
I would have to say the most time consuming part is peeling and slicing the potatoes...
And of course the time it takes to bake them.
One way you can save time on slicing is by using a mandoline. And this is mandoline I own.
Which is really pretty efficient for making these but unfortunately only gets used when the husband is around ....
Cause I prefer to slice them by hand myself rather then using a really sharp object like the mandoline.
Once you get them peeled and sliced I like to put them in a bowl of cold water to keep them from browning while I'm preparing the sauce and chopping onions and garlic.
Ingredients needed
- Russet potatoes
- Half & half cream
- Sour cream
- Butter
- Cheese
- Cornstarch
- Seasonings
Once you've gathered and measured out the ingredients it's pretty easy. The cheesy sauce is made starting with a roux consisting of cornstarch, butter and seasonings....
Then you'll add the half & half cream and sour cream and simmer till thickened. Turn off burner and add cheese.. stir till melted and gooey.
Layer the chopped onions & garlic over the potatoes, the cheesy sauce, and repeat... Top with extra shredded cheese...
Cover and bake and remove cover last 15 minutes of baking for additional cooking and browning time.
Recipe tips
- Make sure to thinly slice the potatoes- mine are approximately ⅛ inch thick
- Prep all ingredients prior to starting
- Use freshly grated cheese that you've grated yourself- don't buy the shredded bags
- Grease the pan with butter, olive oil or cooking spray
- Cover the pan with parchment paper and then foil on top of that- keeps stuff from sticking
- Carefully remove the cover at the end- there will be a lot of steam
- You can broil the top the last few minutes to get a golden brown top- just make sure to watch it carefully
- Allow to cool thoroughly before storing in the fridge
Can I make these ahead
This is definitely a great make ahead recipe. Especially since it takes a while to bake.
If I'm planning on serving this for the holidays I'll usually make them a day or two ahead in advance.
They are also super yummy as leftovers and re-heat easily.

Confession: I'm a little bit afraid of a mandoline slicer too! I love the look of these potatoes. I'm so glad to find a recipe that doesn't include mushrooms!

Omggggg I love scalloped potatoes! Do you use a mandolin slicer to cut the potatoes or slice by hand?

By hand...I like to be able to control thickness of potatoes..Like them a little on the thicker side.
