Cook outside the casserole box with this inventive gratin. Granny Smith apples lend seasonal flavor, while plenty of Swiss and Parmesan cheeses make this dish a savory indulgence that all your guests are sure to love.

How to Make It

Step 1

Heat oven to 400º F. Coat a 3 1/2-quart casserole with cooking spray. In a medium bowl, whisk together the eggs, buttermilk, thyme, salt, and pepper; set aside. Arrange a layer of slightly overlapping potatoes in the casserole. Cover with a layer of apples and sprinkle with a third of each cheese. Pour a third of the egg mixture on top. Make 2 more layers. (Can be made up to 6 hours ahead.) Bake, covered, 1 hour, 15 minutes. Remove cover and bake another 15 minutes or until the potatoes are tender. Remove from oven. Serve warm or at room temperature.

Step 2

Note: Assemble 3 casseroles to serve Put one in the oven every 45 minutes so there is always a fresh gratin on the buffet.

While the idea's a good one, this is definitely not worth making again without some serious modifications. It was a curdled unappetizing looking mess, lacking in flavor - a total waste of good ingredients. You can do much better.

Very dissapointed!. Followed recipe exact. 2 1/2 hours later still had raw potatoes in a bowl of soupy cheeze! Have never had something new turn out this bad!
