FAQs
Can I use canned sweet potatoes instead of fresh?
Using fresh sweet potatoes is recommended, but if you’re short on time, canned sweet potatoes can work in a pinch. Just make sure to drain them well.
What can I substitute for heavy cream?
If you want a lighter option, you can use half-and-half or a mixture of milk and sour cream. However, this may alter the dish’s creaminess.
Can I prepare the gratin ahead of time?
Yes! You can prepare it the day before and store it in the refrigerator. Just add a few extra minutes to the baking time if you bake it straight from the fridge.
