Can I use a different cheese?
Yes, Swiss, Monterey Jack, Gruyère, or mozzarella can be used.
Why is my casserole watery?
This happens if potatoes release too much moisture. Pat them dry before layering and avoid using low-fat milk.
Can I make this in advance?
Yes, assemble up to 24 hours ahead and refrigerate. Bake when ready to serve.
