Blue Cheese Potato Gratin - cooking recipe

Ingredients

3 large russet potatoes, scrubbed well and very thinly sliced
1 cup heavy cream
1/2 cup crumbled blue cheese
kosher salt
fresh ground black pepper, to taste
1/4 cup freshly grated parmesan cheese, for garnish

Preparation

Preheat oven to 350 degrees F; lightly butter or oil a 9\"x13\" baking pan.
Rinse the potato slices in cold water then pat dry.
You're going to make three layers of potato slices, cheese/cream, salt/pepper: layer 1/3 of the slices in the bottom of the prepared pan, then top with 1/3 of the cheese, cream, salt, and pepper.
Repeat twice with remaining ingredients (except garnish).
Bake uncovered at 350 degrees F for 50 minutes or until the potatoes are tender and the top is browned and bubbling.
Sprinkle with freshly grated Parmesan, and serve hot.
