Try using Crab Supreme or Simply Surimi if Crab Classic is unavailable.
For extra crunch, add toasted almonds or walnuts to the breadcrumb topping.

Storage

Store any leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F until warmed through to maintain the crispy topping, or use a microwave for a quicker option though the topping may soften.
