Directions

- Pour the French onion soup evenly over the potatoes, making sure some of the onion strands settle down between the slices.
- Drizzle the heavy cream over the top, then gently press the potatoes down with the back of a spoon so the liquid runs through the layers.
- Cover the dish tightly with foil and bake for 45 minutes.
- Remove the foil, sprinkle the shredded Swiss cheese evenly over the top, and return the dish to the oven for 20 to 25 minutes more, until the potatoes are tender and the cheese is melted and lightly browned.
