Butternut Squash and Potato Gratin with Fresh Sage
Every time I make this gratin I get the same response: “This is so good!” Honestly, though, when you combine potatoes and squash with cream, sage, and cheese, how could it not be amazing? This gratin is especially well suited for dinner parties or any other time you need a hearty, make-ahead side dish. It scales up easily (just increase the ingredients and baking dishes accordingly), and it reheats wonderfully.
