MethodIn large skillet, melt 2 tbsp of the butter over medium heat; cook onions, stirring occasionally, until tender and golden, about 25 minutes. Set aside.
Makeahead: Refrigerate in airtight container for up to 2 days.
Meanwhile, in saucepan, melt remaining butter over medium heat; cook flour, rosemary, salt and pepper, stirring, for 1 minute. Gradually whisk in milk; cook, whisking constantly, just until thickened, about 8 minutes.
Layer one-third of the potatoes in greased 12-cup (3 L) casserole dish; spread half of the onions over top.
Sprinkle with one-third of the cheese. Repeat layers once. Top with remaining potatoes; pour sauce over top, using knife to lift layers and ease sauce between them. Sprinkle remaining cheese over top.
Cover and bake in 375 F (190 C) oven for 1 hour. Uncover and bake until top is lightly browned and potatoes are tender, about 15 minutes. Let stand for 5 minutes before serving.
