My only deviation from her wonderful recipe is to reserve the breadcrumb Parmesan cheese topping until right before I put it in the oven. That's something for me to say since I modify every recipe I find, this one is darn near perfect. The recipe states it serves 6-8 but I've found at a buffet or a potluck, when you are serving other dishes, it will feed more like 8-10.
This is also one of the "bullet-proof" casseroles that can be reheated without any problem so next day lunch is most tasty. After a big party the last thing you want to do is cook but reheat, yum.
This is one of my go-tos, what about sharing some of your party pleasers.
Editors note: Pardon this crummy photo. I had ten in the buffet line and forgot to take the beauty shot before I called them to dinner. Never try to come between hungry guest and the food. Sheesh.
