vegetable lasagne

This was so good. Look at the picture. I don't think I need to say much else.

Except ... If you're one of those people that thinks a meal isn't a meal without meat, you are so missing out.

Vegetable Lasagne
makes 1 9x13 pan
1 package no-boil lasagne noodles (I like Barilla)
1 9 oz bag of baby spinach leaves
1 lb mushrooms, sliced (I used white button, but cremini or shiitake would be delicious, too. Use a variety!)
4 T butter
4 T flour
4 C milk (I used 2 C 1% and 2 C whole)
1/2 onion, minced
pinch of freshly grated nutmeg
salt and pepper to taste
2 C grated mozzarella cheese
1~2 C freshly grated parmesan or pecorino romano cheese

1. Preheat the oven to 375°F.
   
2. In a large skillet, melt 1 tablespoon of the butter over medium-high heat. Add half of the mushrooms and season gently with salt and pepper. Cook, tossing once in a while, until juices are released and evaporated and the mushrooms are browned. Transfer to a plate and repeat with the second half. (You never want to crowd mushrooms or they won't brown properly)
   
3. In a large saucepan, melt 2 tablespoons of butter over medium heat and add the onion with a little salt and pepper. Cook the onion until softened but not browned. Add the flour and stir until there are no more dry spots left and flour is cooked and slightly golden.
4. Add 1/2 C of the milk, and whisk vigorously until no lumps remain. Continue to repeat with the addition of milk in small portions until all the milk is used up and the sauce can coat the back of a spoon.
5. Add the spinach to the sauce and stir gently until spinach is wilted. Take the pan off the heat.
6. In a 9x13-inch lasagna pan, pour a little bit of the sauce and layer 3 lasagna noodles on top. Top with 1/3 of the mushrooms, 1/2 C of sauce, 1/2 C of mozarella, and a couple tablespoons of parmesan. Add noodles and repeat. On the top layer, use 1/2 C of sauce, 1/2 C of mozarella, and the remaining parmesan.
7. Cover with foil and bake 45 minutes. Remove the foil and bake under the broiler for 5~10 minutes until the cheese is golden and bubbly. Let cool for 15 minutes before serving.
