This gratin almost reminds me of my favorite childhood vegetable – creamed spinach. I know, how weird is it that a kid loved creamed spinach? So really this Creamy Collard Green Gratin dish is a combination of all my favorite flavors. To make this super creamy I opted to use cream cheese instead of a typical béchamel sauce. And I pretty much love anything that is made in a cream cheese sauce. Top with a slightly crispy panko crust, and you have the perfect green vegetable Thanksgiving side dish that is also creamy and rich.
