Recipe View 5 mins Remove from the oven and let stand for 5-10 minutes before serving. This allows the au gratin to set slightly, making it easier to serve. (10 minutes)

For a richer flavor, use Gruyere or a blend of Gruyere and Cheddar cheese.
To ensure even cooking, slice the squash and apples as thinly and uniformly as possible.
This dish can be assembled ahead of time and refrigerated for up to 24 hours before baking. Add 10-15 minutes to the baking time if baking from cold.
Vegetarian Option: Omit the bacon and use vegetable stock. Consider adding a pinch of smoked paprika to the flour mixture for a smoky flavor.
