Frequently Asked Questions

Yes, you can prepare the casserole in advance and store it in the refrigerator for up to 24 hours before cooking. Just cover it tightly to prevent drying out. When ready to serve, microwave it on high until heated through, adding a few extra minutes if it's been chilled.

What can I use instead of cream of chicken soup?
