You could call this the casserole of many names. You might know it as Special Delivery Chicken or more plainly, Poppy Seed Chicken, but whether or not you’ve heard it called Sorority House Poppy Seed Chicken Casserole before, you’ve probably had it a time or two. See, it doesn’t matter what you call it – it’s plain delicious, with a creamy poppy seed-studded sauce and a buttery cracker crumb topping that’s pretty much impossible to resist.

Oh, this is also really easy to make. But isn’t that generally the case with most casseroles that stand the test of time? It’s a cream of chicken soup type of casserole, so it’s easy to whip up at a moment’s notice, but it’s made extra creamy with the addition of sour cream and extra flavorful thanks to some garlic powder, Parmesan cheese, plenty of black pepper, and of course the delicate crunch of poppy seeds.

It’s the perfect use for leftover chicken and it’s great over white rice, but maybe the thing that keeps you coming back for more the most is the topping. Made up of melted butter and crushed Ritz-style crackers, it leaves basic breadcrumbs in the dust.
