Fry bacon until crisp and drain on a paper towel.

Cut the fried bacon into bite-sized pieces.

Spread the bacon pieces evenly on the bottom of the unbaked pie shell.

In a mixing bowl, beat eggs, heavy cream, salt, pepper, and nutmeg until just blended.

Stir in the grated Swiss cheese into the egg mixture.

Pour the egg and cheese mixture into the pie shell, over the bacon.

Bake in a preheated oven at 375°F (190°C) for about 35 minutes.

Check for doneness: the pie shell should be golden brown and the filling firm.

Remove from oven and let cool slightly before serving.

Serve warm as an entree.
