Can I make this recipe ahead of time?

Yes. I often prep the layers in the morning and keep the covered dish in the fridge. When it is time to cook, remove it from the fridge for a few minutes so it is not stone cold, then bake as directed. This saves you the evening rush and still gives a fresh, warm dish at dinner.

Can I use frozen cranberries?

Absolutely. Thaw and pat them dry to avoid adding extra liquid to the gratin. Frozen cranberries are a great substitute when fresh are out of season, and they still provide that bright tartness.

How can I make the top extra crunchy?

Toast the breadcrumbs first and add an extra tablespoon of melted butter. If needed, broil for the last 60 to 90 seconds while watching closely. Keep the oven door open a crack and be ready to pull it out as soon as it reaches the color you want.

Is this suitable for a vegetarian dinner?

Yes. The gratin is rich and satisfying on its own with a green salad and maybe a bowl of lentils or beans on the side. For added protein, you can stir in cooked chickpeas or serve it alongside a tofu dish.

What can I pair with this for a holiday meal?

This gratin pairs beautifully with roast turkey or pork. Its sweet and tart notes balance richer main courses, and it will sit happily on a holiday table next to cranberry sauce and roasted roots.

Instructions

Preheat the oven to 375°F (190°C).
In a greased baking dish, layer half of the sweet potatoes.
Sprinkle half of the cranberries and half of the Gruyère cheese over the sweet potatoes.
Pour half of the heavy cream over the layer.
Repeat the layers with the remaining ingredients.
In a bowl, mix breadcrumbs with melted butter, then sprinkle on top of the final layer.
Season with salt, pepper, and herbs if using.
Cover with foil and bake for 30 minutes.
Remove the foil and bake for an additional 15 minutes or until the top is golden and bubbly.
Let it cool slightly before serving.

Notes

Use a good quality Gruyère for the best flavor. If you don’t have heavy cream, a mix of milk and a splash of butter will suffice.
