You might not be familiar with the term gratin or au gratin and what the difference is between scalloped potatoes and Potatoes au gratin.
“au gratin” seems to be given several alternative definitions. Today we’re going with the Webster’s dictionary definition referring to a dish that is baked with a topping of breadcrumbs and cheese.
What is the difference between scalloped potatoes and au gratin potatoes?
Both dishes are rich and creamy, including round slices of potatoes baked in a casserole dish. But there are a few things that set them apart.
The first one being - cheese!
Scalloped potatoes are usually made with thin potato slices layered in a casserole dish and baked with heavy cream, milk, or both. Often the cream is accented with some additional flavors like garlic or fresh herbs.
In comparison, potatoes au gratin use cheese to create a richer, more indulgent dish. The grated cheese is sprinkled between potato layers, and breadcrumbs are also often sprinkled on top of the dish before it goes into the oven.
Also, both dishes use round potato slices, but au gratin potatoes often use a thinner slice.
Over the years, these definitions have come to be used very loosely and often you’ll find recipes that don’t actually use the original ingredients or methods. It’s ok. Any combination of potatoes, cream, and cheese is just fine with me.
I took some liberties with today’s recipe. You know I can’t help myself! 😀
It’s actually a hybrid of the two dishes with the addition of sweet potatoes as well regular potatoes.
Let’s talk how to make this scrumptious potato recipe – shall we?
How to make scalloped potatoes:
- First heavy cream is simmered for a few minutes with butter, fresh minced garlic and chopped herbs like thyme and sage. Then taken off the heat and set aside.
- Next, the skins from the potatoes are removed. Then they’re thinly sliced and tossed in salt and pepper.
- The potatoes are arranged in a 9x13 casserole dish. Alternating the two potato types and overlapping them.
- Then they’re topped with the heavy cream mixture.
- And finally sprinkled with gruyere cheese...
- ... covered and baked for 30 minutes, then uncovered and baked for 15 more minutes until the potatoes are tender and the cheese is slightly browned or golden.
