Recipe Notes

To make this recipe gluten free, replace the flour with cornstarch and use a gluten free alternative bread crumb mixture.

To assemble the casserole in advance and bake later, assemble the whole casserole and skip the bread crumbs. Add the bread crumb mixture immediately prior to baking when ready.
