Portobella Mushroom Lasagna

I made this Lasagna last week and I thought it was AMAZING.  It really was easy and would be delicious if you added some spinach or even more mushrooms than recommended.  Mushrooms cook down so much that I think the more the better!! The best part about the recipe is that you can make the entire thing ahead of time too.  So I made it all during nap time and then it was ready to just throw in the oven when we were ready to eat.

 I thought it was fitting to share an Ina Garten recipe today because I just got notice that her new cookbook, Cooking for Jeffrey, just shipped to me!!! Yippy!!  I can't wait to read it.

Portabello Mushroom Lasagna

Kosher salt
Good olive oil
3/4 pound dried lasagna noodles
4 cups whole milk
12 tablespoons (1-1/2 sticks) unsalted butter, divided
1/2 cup all-purpose flour
1 teaspoon freshly ground black pepper
1 teaspoon ground nutmeg
1-1/2 pounds portobello mushrooms
1 cup freshly ground Parmesan

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.

I hope you enjoy :)
