Servings: persons

2 tablespoons butter
2 leeks, sliced
3 garlic cloves, minced
1 tablespoon chopped fresh rosemary
2 teaspoons sea salt
1 teaspoon cracked black pepper
2 pounds Yukon gold potatoes, very thinly sliced
2 cups heavy cream
1 cup whole milk
1 cup (4 ounces) shredded Gruyere cheese
1/2 cup (2 ounces) grated Parmesan cheese
Garnish: fresh rosemary leaves

1
Preheat oven to 400u00b0. Melt butter in a large, deep skillet or saucepan over medium-high heat. Add leeks and garlic; saute 5 to 7 minutes or until tender. Stir in rosemary, sea salt, and pepper.
2
Add potatoes, cream, and milk to leek mixture in pan, stirring gently to combine. Bring mixture to a boil, reduce heat, and simmer, uncovered, 10 to 15 minutes or until potatoes are barely tender. (Do not overcook. Potatoes will be pliable, but not fully cooked.)
3
Spoon half of potato mixture into a lightly greased 2 1/2-quart baking dish. Sprinkle with 1/2 cup Gruyere cheese and 1/4 cup Parmesan. Top with remaining potato mixture; sprinkle with remaining cheeses. (May be covered and refrigerated overnight. Let come to room temperature before baking.)
4
Bake 20 to 30 minutes or until potatoes are tender and top is golden brown. Garnish, if desired.
