Cheesy Hasselback Potato Gratin Recipes

Steps:

• Preheat the oven to 450 degrees F and line a baking sheet with foil.
• In a small saucepot, bring the butter, oil and garlic to a boil over high heat; remove from the heat.
• Using 2 wooden spoons placed on each side of a potato as a guide, cut the potato into thin slices about 1/8 to 1/4 inch thick, without cutting through the bottom (the spoons will keep you from cutting all the way through the potato). Repeat with the remaining potatoes. Place the potatoes on the prepared baking sheet and brush each potato with some of the butter mixture, trying to get the butter between the slices. Sprinkle each potato with salt and pepper.
• Bake for 30 minutes, then remove the potatoes from the oven. The potatoes will have started to spread out from cooking and it will be easier to brush each slice with some more of the butter mixture. Put the potatoes back in the oven for an additional 20 minutes.
• Remove the potatoes from the oven again and sprinkle the Parmesan over the top and into the slices. Return to the oven to melt and brown the cheese, an additional 5 minutes. Serve the potatoes immediately.

Steps:

• Adjust oven rack to middle position and heat oven to 400 degrees. Combine cheeses in a large bowl. Transfer 1/3 of cheese mixture to a separate bowl and set aside. Add cream, garlic and thyme to cheese mixture. Season generously with salt and pepper. Add potato slices and toss with your hands until every slice is coated with cream mixture, making sure to separate any slices that are sticking together to get the cream mixture in between them.
• Grease a 2-quart casserole dish with butter. Pick up a handful of potatoes, organizing them into a neat stack, and lay them in the casserole dish with their 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 casserole. Pour the excess cream/cheese mixture evenly over the potatoes until the mixture comes halfway up the sides of the casserole. You may not need all the excess liquid.
• Cover dish tightly with foil and transfer to the oven. Bake for 30 minutes. Remove foil and continue baking until the top is pale golden brown, about 30 minutes longer. Carefully remove from oven, sprinkle with remaining cheese, and return to oven. Bake until deep golden brown and crisp on top, about 30 minutes longer. Remove from oven, let rest for a few minutes, and serve.
