Ingredients

4 tbsp salted butter (optional)
3 lb leeks
1 1/2 cups whole milk
1 cup heavy cream
2 oz blue cheese
3 large garlic cloves
1 tbsp stone ground mustard
1/4 tsp freshly grated nutmeg
3/4 tsp kosher salt
1/2 tsp freshly ground black pepper
6 oz grated gruyère cheese
2 oz freshly grated parmesan cheese
2 lb russet potatoes

Steps

Heat the oven to 375 F and grease a 9-by-13-inch baking dish with butter or oil.
Slice the leeks and potatoes thinly, then rinse the leeks well.
Cook the leeks in a large skillet with the butter for 10 minutes, until soft.
Whisk the milk, cream, blue cheese, garlic, mustard, nutmeg, salt, and pepper in a bowl.
Layer the potatoes and leeks in the baking dish, then pour the cream mixture over them.
Cover and bake for 55 minutes, then uncover and top with Gruyère and Parmesan.
Bake for 20 minutes more, until the potatoes are tender and the cheese is browned.
