This stunning vegetarian Thanksgiving main dish belongs at the center of any table. Beneath a crispy, wispy golden crust of store-bought phyllo lies a gratin with layers of creamy autumnal vegetables in a colorful ombré pattern. Slice the vegetables very thinly using a mandoline for safety and ease (see Tip), and they’ll bake up tender and creamy. Because each vegetable has varying densities and sugar levels, they benefit from individual attention: Salt each layer zealously, as the vegetables need a significant amount to offset their natural sweetness, and they really soak up the sauce. The sweet potatoes and squash may be sliced before you start cooking, but the potatoes should be done later, to prevent them from oxidizing, and the beets, to prevent them from falling apart. This creamy root vegetable gratin is exacting, and requires some effort, but its wow factor justifies the labor.
