The holiday season is really ramping up and with Thanksgiving behind us now……I’m ready to dive headfirst into all the comfort dishes! Anything in a casserole dish, covered with cheese and swimming in heavy cream is fair game and so this easy Potatoes Au Gratin recipe is instantly on repeat.

POTATOES AU GRATIN

I grew up eating cheesy Au Gratin Potatoes but, most of the time, they were from a box. Which is totally OK in my book…..I’m not judging anyone if you have ever made box potatoes but these are amazing and completely from scratch.  

I mean, seriously, what’s better than paper thin potato slices baked in a creamy sauce of butter, garlic and cream with tons of cheese tossed in for good measure. Comfort food doesn’t get any better than this my friends.

HOW TO MAKE AU GRATIN POTATOES

It seems pretty fancy to say, but this recipe is super simple to make and even easier if you can slice them up using a mandoline or your slicing blade of a food processor.

  1. Preheat oven to 350°.
  2. In a large saucepan, melt the butter over low heat. Stir in the garlic and cook 1 minute. Whisk in the cornstarch, salt and pepper until smooth.
  3. Gradually add the milk, or half and half, and bring to a boil. Cook the sauce stirring constantly until thickened, approximately 2-3 minutes.
  4. Remove from heat and stir in 1 1/2 cups of the cheese until melted. Stir in the potatoes.
  5. Transfer to a 2 quart baking dish coated with cooking spray. Sprinkle with the remaining cheese. Cover and bake 30 minutes. Uncover and bake an additional 30-45 minutes or until the potatoes are tender and the sauce is golden brown and bubbling.
  6. Remove from the oven and allow to stand 5-10 minutes before serving.

This recipe calls for cheddar but sometimes I like to make my Potatoes au Gratin with gruyere for an extra sharp and swiss cheesy bite. I believe the Potatoes au Gratin Ina Garten makes use gruyere and cheddar…..the more cheese, the better if you ask me!

THE DIFFERENCE BETWEEN AU GRATIN AND SCALLOPED POTATOES

While the base of Scalloped Potatoes and Potatoes Au Gratin are, basically, the same….Au Gratin is commonly made with layers of cheese in between the layers of potatoes. Then, it’s commonly topped with a crispy crunchy topping of breadcrumbs or crackers (or not, it’s up to you) before baking to a cheesy, golden brown crust.

Scalloped potatoes, on the other hand, are usually just thinly sliced potatoes baked in cream without cheese….you can make your own homemade scalloped potatoes HERE.

Sometimes, I’ll even throw some leftover ham in there to make it a total one pot dinner like I did with these easy Scalloped Potatoes with ham!
