Assemble individual cups or pie according to recipe. Cover and refrigerate up to 1 day, if you like. Before baking, however, remove dishes from refrigerator and leave at room temperature about half an hour. Then bake, uncovered, in centre of preheated 350F (180C) oven until eggs are set and cheese is melted, from 35 to 40 minutes. Let stand 2 to 3 minutes before serving.
