This golden Cheesy Hasselback Potato Gratin recipe delivers all the creamy delight of a classic potato gratin, with many crispy edges due to the Hasselback potatoes. Additionally, this Hasselback potato gratin satisfies my need for creamy and cheesy goodness.
Mixing a potato gratin with Hasselback roast potatoes, we tend to deliver the best creamy-in-the-middle, crispy-on-top casserole. It’s excellent for the Thanksgiving or Christmas table or any night you would like a show-stopping dish.
Why is Hasselback Potato Gratin so good?
By the arrangement of the potatoes accordion-style, rather like with Hasselback roasted potatoes, you get an ultra-crispy top with a creamy, cheesy and tender center.
Tossing the potato slices with the cream and cheese combination guarantees equal distribution within the baking dish.

How to make Cheesy Hasselback Potato Gratin

- Grease a skillet with butter nicely.
- Take a handful of potatoes, arrange them into a neat stack, and lay them within the skillet with their edges aligned vertically.
- Continue putting potatoes in a casserole, operating around the perimeter and into the middle till all potatoes are added.
