Potatoes Au Gratin – thinly sliced potatoes layered with a deliciously thick cream sauce and topped with cheddar cheese. Such a great side dish for any type of meal and so much easier to make than you think!
Cheesy potatoes are one of those foods that everyone loves. It doesn’t matter what form they are in, when you say that is what is for dinner people get excited. Loaded Twice Baked Potato Casserole is a version that has mashed potatoes with cheese and bacon and is over the top amazing. These Au Gratin Potatoes are thinly sliced and then topped with cheese that gets all melty and delicious.
I love this potatoes au gratin recipe because of how simple it is. It really is just a few ingredients and not much work. The hardest part is slicing the potatoes. If you have a mandoline this is the time to break it out! You want the potatoes sliced as close to the same thickness as possible, so they cook at the same rate.
Scalloped Potatoes vs Au Gratin Potatoes
This is the big question that gets asked every time one of these recipes is made. The main difference comes down to the cheese. Scalloped potatoes are cooked in a very similar cream sauce they are just not topped with cheese. Au Gratin Potatoes always have melted cheese on top. Both use thinly sliced potatoes that are arranged in a casserole dish and baked until soft and tender.
The Best Potatoes for Potatoes Au Gratin
Russet potatoes are my favorite to use. They contain the most starch, so as they cook down it makes for the creamiest sauce. You can use red potatoes as well if you have them, but russets are my favorite.
How to Make Potatoes Au Gratin
- Thinly slice the potatoes. This is the time to break out your mandoline slicer. If you don’t have one, you can get a relatively inexpensive one for under $20 at Amazon. Trust me, it is worth the investment even if you only break it out a couple times a year.
- Arrange the potatoes in a casserole dish. You don’t want to just stack them tall, you want to have space between them and make them somewhat pretty. In addition to appearance, it allow the sauce to get into all the open areas and really cover the potatoes.
- Cover with the delicious cream sauce. You just pour over the potatoes trying to make sure that everything is covered.
- Bake – these do take awhile to bake. I start with them covered so that potatoes can actually cook without burning. Then cover with cheese to finish baking.
Homemade au gratin potatoes are so much easier to make than they appear. They are perfect for your next holiday meal or even Sunday dinner. They do take awhile to bake, but really most of the time involved is hands off. These are perfect to make if you have leftover ham from the holiday, just mix it in when you layer the potatoes and it will blend with everything and be absolutely delicious!
