Any yummy cheese will make a delicious frittata. If you do not have chives and parsley, season with other dried Mediterranean herbs such as oregano and basil. For simplicity, rather than peeling steamed potatoes I prefer chopping unpeeled potatoes into a ½ inch dice, bring to a boil in a medium sauce pan and simmer until just tender, about 6 minutes. If you are adding veggies, cook them in with the leeks. You may need extra butter or oil for cooking. Making a frittata is not an exact science. Change any of the quantities to suit your family size. Of course, fewer eggs will reduce your cooking time. Personally, we would use a cast iron pan and not a pan with a plastic handle since frittatas are finished in the oven.
1/2 lb potatoes
3 cups thinly sliced white and pale green part of leek, washed well and drained
2 tablespoons unsalted butter
12 large eggs
1 cup freshly grated Parmesan
1 cup coarsely grated Gruyere
2 tablespoons snipped fresh chives
2 tablespoons minced fresh parsley leaves
2 tablespoons olive oil
In a steamer set over boiling water steam the potatoes, covered, for 20 to 25 minutes, or until they are tender, and let them cool until they can be handled. Peel the potatoes and cut them crosswise into thin slices. In a 12-inch non-stick skillet cook the leek in the butter over moderately low heat, stirring, for 12 to 15 minutes, or until it is very soft, and add salt and pepper to taste. ( Add your veggies here.) In a large bowl whisk together the eggs, add 1/2 cup of the Parmesan, 1/2 cup of the Gruyere, the chives, the parsley, and salt and pepper to taste, and whisk the mixture until it is combined well. Stir in the leek and the potatoes. In the skillet, cleaned, heat the oil over moderate heat until it is hot but not smoking, pour in the egg mixture, distributing the potatoes evenly, and cook the frittata, without stirring, for 14 to 16 minutes, or until the edge is set but the center is still soft. Sprinkle the remaining 1/2 cup Parmesan and the remaining 1/2 cup Gruyere over the top. If the skillet handle is plastic, wrap it in a double thickness of foil. Broil the frittata under a preheated broiler about 4 inches from the heat for 4 to 5 minutes, run a thin knife around the edge, and slide the frittata onto a serving plate. Cut the frittata into wedges and serve it warm or at room temperature.
