Oyster Casserole topped with Parmesan cheese and golden Panko crumbs makes an elegant addition to your holiday menu.
An oyster casserole is a must for our Christmas dinner. Usually we make a really simple one with oysters, crushed Saltine crackers, butter, and cream, but this year I wanted to change it up a little. This recipe is based off of one I saw in the December 2016 issue of Southern Living magazine.
It’s rich and creamy just like an Oyster Casserole should be, but it also has lots of different flavors: onion, celery, red bell pepper, mushrooms, garlic, plus a hint of nutmeg.
We liked it so much, it just might become a regular our Christmas menu.
