Yukon Gold Potato and Wild Mushroom Gratin with Blue Cheese

We went mushroom hunting on Sunday morning, and ended up with a handful of morels. This recipe calls for a mix of wild mushrooms, so I used a mix of morels, shiitake, and baby bellas. It was fantastic! I had to cook it a little longer than directed so that the potatoes were cooked all the way through. This is definitely an impressive dish, and it would be impressive with any mix of wild mushrooms.

Bon Appétit November 1996

Use fresh button mushrooms if wild mushrooms are hard to get; you will still have delicious results. Yukon Gold potatoes have a pale yellow color and a buttery taste that adds to the richness of this dish.

5 ounces crumbled blue cheese (such as Stilton, Gorgonzola or Maytag blue; about 1 1 /2 cups), room temperature
2 ½ cups whipping cream
1 teaspoon salt
½ teaspoon pepper
1 ½ tablespoons butter
1 lb. mixed fresh wild mushrooms (such as chanterelle, morel, portobello, stemmed shiitake, oyster, crimini or hedgehog), thickly sliced
1 ½ teaspoons chopped fresh thyme or 3/4 teaspoon dried
2 lbs. Yukon Gold potatoes, peeled, very thinly sliced into rounds

Position rack in top third of oven and preheat to 400°F. Butter 13 x 9 x 2-inch glass baking dish. Place cheese in medium bowl; add 1 cup/2 cream. Using fork, mash mixture to chunky paste. Mix in 1 teaspoon salt and 1/2 teaspoon pepper. Mix in remaining 2 cups cream.
