Preheat the oven to 375 degrees F.
Bring a large pot of water to a boil with 1 tablespoon salt and a
splash of oil. Add the lasagna noodles and cook for 10 minutes,
stirring occasionally. Drain and set aside.
For the white sauce, bring the milk to a simmer in a saucepan.
Set aside. Melt 8 tablespoons (1 stick) of the butter in a large
saucepan. Add the flour and cook for 1 minute over low heat,
stirring constantly with a wooden spoon. Pour the hot milk into
the butter-flour mixture all at once. Add 1 tablespoon salt, the
pepper, and nutmeg, and cook over medium-low heat, stirring
first with the wooden spoon and then with a whisk, for 3 to 5
minutes, until thick. Set aside off the heat.
Separate the mushroom stems from the caps and discard the
stems. Slice the caps 1/4-inch thick. Heat 2 tablespoons of oil
and 2 tablespoons of the butter in a large (12-inch) saute pan.
When the butter melts, add half the mushrooms, sprinkle with
salt, and cook over medium heat for about 5 minutes, until the
mushrooms are tender and they release some of their juices. If
they become too dry, add a little more oil. Toss occasionally to
make sure the mushrooms cook evenly. Repeat with the
remaining mushrooms and set all the mushrooms aside.
To assemble the lasagna, spread some of the sauce in the
bottom of an 8 by 12 by 2-inch baking dish. Arrange a layer of
noodles on top, then more sauce, then 1/3 of the mushrooms,
and 1/4 cup grated Parmesan. Repeat 2 more times, layering
noodles, sauce, mushrooms, and Parmesan. Top with a final
layer of noodles and sauce, and sprinkle with the remaining
Parmesan.
Bake the lasagna for 45 minutes, or until the top is browned the
sauce is bubbly and hot. Allow to sit at room temperature for 15
minutes and serve hot.
