Crispy Cheesy Potato Gratin

Directions

1. Adjust oven rack to middle position and heat the oven to 400 degrees.

2. Combine the cheeses in a large mixing bowl. Transfer one third of the cheese mixture to a separate bowl and set aside. Add the cream, garlic, Potato Slayer seasoning, and salt to the mixing bowl. Add potato slices and toss until all the slices are coated with cream mixture.

3. Grease a 2-quart casserole dish with butter. Scoop up a handful of potatoes, shape them into a neat stack, and place them in the casserole dish with the thin edges aligned vertically. Continue placing potatoes in the dish, working around the perimeter and into the center until all the potatoes have been added. The potatoes should be very tightly packed. (If necessary, slice an additional potato, coat with cream mixture, and add to the casserole.)

4. Pour any remaining cream/cheese mixture evenly over the potatoes until the mixture comes halfway up the sides of the casserole. Cover the dish tightly with foil, place it on a rimmed baking sheet, and transfer to the oven. Bake for 30 minutes.

5. Remove foil and continue baking until the top is pale golden brown, about 30 minutes longer. Carefully remove the pan from the oven, top with the remaining cheese, and return to the oven.

6. Bake for approximately 30 more minutes, until the top is crisp and deeply golden brown. Remove from the oven, let rest for 5-10 minutes, and then serve.
