Generously butter a 3-qt shallow baking dish.
Cut a round of parchment paper to fit just inside a 12-inch heavy skillet, then set parchment aside.
Halve leeks lengthwise, then cut crosswise into 1 1/2-inch pieces (you should have about 8 cups).

Meanwhile, peel potatoes and slice crosswise 1/16 inch thick with slicer.
Transfer to a large heavy pot with cream, milk, thyme, 1 tsp salt, and 1/2 tsp pepper and bring to a boil over medium heat, stirring occasionally (liquid will thicken).
