Gratin potatoes are originally a French dish consisting of thinly sliced potatoes baked with cream and topped with a crust of cheese and/or breadcrumbs and butter. It is a rich, comforting dish made even more special here with the addition of delicate pumpkin slices and aromatic thyme, rosemary, and garlic. These flavors take what can be something of a one-note dish and transform it into a complex and deeply comforting culinary delight.
his dish is rooted in fall’s abundance and makes use of seasonal ingredients to create something that won’t just warm the chill in your bones, but might make you grateful for the start of the cozy season.
