How long will this casserole keep?

Store covered in the refrigerator for up to 4 days. Reheat portions in the microwave or warm the whole dish in the oven.

Can I freeze this casserole?

Yes, freeze for up to 3 months. Thaw overnight in refrigerator before reheating. The texture may be slightly softer after freezing.
