Frequently Asked Questions

Can I prepare the casserole ahead of time?

Yes, you can prepare the casserole a day in advance. Simply assemble it without baking, cover it tightly with foil, and refrigerate. When ready to bake, allow it to sit at room temperature for about 30 minutes before popping it in the oven.

What can I use instead of sliced cheese on top?

If you prefer a different cheese, shredded mozzarella or Monterey Jack would work well as a substitute for the sliced cheese. You can also mix in some grated Parmesan for added flavor and a crispy topping.

How do I know when the casserole is done?

The casserole is done when it is bubbly and the cheese on top is starting to turn golden brown. You can also insert a fork into the potatoes to check if they are tender. If they are soft, the casserole is ready to serve.
