Preparation

Step 1

1. Preheat oven to 400 degrees and butter a 2-quart baking dish.
2. In a large saucepan, combine milk, salt, pepper, chile powder and nutmeg. Heat to boiling over a medium high flame. Add potatoes and return to a boil; simmer a few minutes until mixture thickens slighly. Remove pan from heat, stir in mustard.
3. With a slotted spoon, transfer half the potatoes to baking dish; place in an even layer. Sprinkle with 1/2 cup Gruyere. Top with remaining potatoes, pour milk mixture over potatoes and sprinkle with remaining cheese. Bake 45 minutes, until potatoes are tender and top is golden.
