Chicken Divan was first invented at the Divan Parisienne Restaurant in the New York City Chatham hotel. A mixture of chicken, broccoli, almonds, and a cheese sauce, the dish is a classic casserole. The recipe below calls for both Parmesan and cheddar cheese for a super-rich cheese sauce.
The only slightly technical part of this recipe is making the béchamel sauce, which is the base of the cheese sauce. To do this, you'll need to whisk the butter and flour together until smooth, then slowly add the milk until you get a nice, thick sauce into which you can melt the cheese.
