A full cup of butter and 1 1/2 cups of half-and-half make for an ultra creamy and rich casserole. With such a rich taste, it’s more of a special occasion casserole than an every day casserole.
Make Ahead
This casserole can be prepared up to 8 hours in advance and then baked just before serving.
Panko Crumb Topping
To give the casserole a little texture and more flavor, there’s a buttery Panko crumb topping with a little Parmesan cheese.
