Preparation
Step 1
Preheat the oven to 350°F and adjust an oven rack to the middle position. In a large bowl, toss the cheeses and cornstarch together until evenly coated.
In a large gratin dish (about a 2- to 3-quart dish), shingle half of the potatoes. Sprinkle the potatoes evenly with 1 1/2 cups of the cheese mixture, 1/2 teaspoon salt, and 1/4 teaspoon pepper. Top with the remaining potatoes, shingling them neatly and evenly. Sprinkle another 1/2 teaspoon salt and 1/4 teaspoon pepper evenly over the top.
Combine the cream and the broth in a large measuring cup and pour the mixture over the potatoes. Top with the remaining cheese mixture and bake until golden brown and a fork inserted into the center slides in easily with little resistance, 75 to 85 minutes. Let the potatoes cool for 10 minutes. Serve.
Cook's note:
The key to this dish is the evenly sliced potatoes. It will be nearly impossible to accomplish this feat by hand, since the potatoes need to be sliced 1/8-inch thick. I don’t have a mandolin, which would work perfectly, however, a slicing disk on a food processor/shredder works great and in a pinch, I’ve used the slicing side of my box grater.
