FAQs

Can I make this casserole ahead of time?

Yes, you can assemble the casserole ahead of time, cover it with foil, and refrigerate it until you're ready to bake. You may need to add a few extra minutes to the baking time if it’s coming directly from the fridge.

Can I use russet potatoes or should I use another type of potato?

Russet potatoes are perfect for this recipe due to their starchy texture, but you could also use Yukon Gold potatoes for a creamier, smoother result.
