Pommes de Terre Mont d' Or
4 cups mashed potatoes, left over or fresh
Preheat the oven to 400 degrees F. Butter a shallow baking dish or casserole.
Put the potatoes in the work bowl of a food processor, then add the eggs, about 1/2 cup of the grated cheese, and salt and pepper. Process briefly, about 10 seconds, to whip all the ingredients together.
Scoop the potatoes into the prepared gratin dish and smooth with a rubber spatula. Scatter the remaining cheese over the top and place on a baking sheet (in case of spills) in the lower part of the oven.
Bake about 30 to 35 minutes, until the top of the gratin is crusty and golden.
See, French cooking is a snap!
