Cheese production increased in the nineteenth century when dairy cooperatives were formed in Minnesota and Wisconsin; now, that area of the country is known for making outstanding cheese. In this recipe, white cheddar goes into a rich and creamy potato gratin that is a great substitute for — or, at a particularly lavish feast, a fine accompaniment to — mashed potatoes.

Preparation
Step 1
Melt butter in heavy large skillet over medium heat. Add breadcrumbs and stir until crumbs are golden brown, about 10 minutes. Cool crumbs (Can be prepared 2 days ahead. Cover and let stand at room temperature.)
Step 2
Position rack in center of oven and preheat to 400°F. Butter 15x10x2-inch (4-quart) glass baking dish. Mix thyme, salt and pepper in small bowl. Combine grated cheddar cheese and flour in large bowl; toss to coat cheese. Arrange 1/3 of potatoes over bottom of prepared dish. Sprinkle 1/3 of thyme mixture, then 1/3 of cheese mixture over. Repeat layering of potatoes, thyme mixture and cheese mixture 2 more times. Whisk chicken broth, whipping cream and mustard in medium bowl to blend. Pour broth mixture over potatoes.
Step 3
Bake potatoes 30 minutes. Sprinkle buttered crumbs over. Bake until potatoes are tender and top is golden brown, about 1 hour longer. Let stand 15 minutes before serving.
