It looks, smells, and tastes like pizza, with one delicious difference: The crust is made of mashed potatoes. You'll have to use a fork to eat this pie, since the slices aren't sturdy enough to hold in your hand.
2 1/2 pounds baking potatoes (about 5), peeled and halved
1 28- ounces can tomatoes, drained and chopped fine (about 1 cup)
1 1/4 teaspoons salt
4 tablespoons olive oil
Fresh-ground black pepper
3/4 pound grated fontina (about 3 cups)
3 cloves garlic, minced
5 anchovy fillets, minced
2 teaspoons dried oregano
1/3 cup grated Parmesan
How to Make It
Heat the oven to 450°. Put the potatoes in a medium saucepan of salted water. Bring to a boil, reduce the heat, and simmer until tender, about 20 minutes. Meanwhile, put the tomatoes in a strainer set over a medium bowl. Toss with 3/4 teaspoon of the salt and let drain for 20 minutes.
Drain the potatoes and push them through a food mill, ricer, or strainer back into the saucepan. Cook over moderately low heat, stirring, until the potato starts to stick to the pan, about 5 minutes. Stir in 2 tablespoons of the oil, the remaining 1/2 teaspoon salt, and a pinch of pepper. Remove from the heat.
Oil a large baking sheet. Spread the potato mixture onto the baking sheet, forming two 6-by-11-inch rectangles. Top the potato with the fontina, leaving a 1/4-inch border. Sprinkle the garlic and anchovies over the cheese. Top with the drained tomatoes followed by the oregano and Parmesan. Drizzle with the remaining 2 tablespoons oil. Bake the potato pies in the lower third of the oven until the cheese is bubbling and the edges are golden brown, about 25 minutes.
Wine Recommendation: Barbera and dolcetto are the everyday workhorse wines of Piedmont. The more acidic and fruitier barbera is the better choice for dishes with a lot of tomatoes.
