1
Preheat the oven to 375F.
-
2
(I waited to do this until after the noodles were cooked and the bechamel sauce was started).
-
3
Bring a large pot of water to boil, with a dash of salt and oil.
-
4
Add the noodles and cook for 10 minutes.
-
5
Drain and set aside if you feel they are going to stick a lot drizzle a bit more oil on them once drained.
-
6
Make the bechamel/white sauce: Bring milk and garlic to a simmer in a saucepan over medium heat.
-
7
Melt one stick of butter in a large pot (I reused the pot that the noodles cooked in) over medium heat.
-
8
When the foam from the butter has subsided, add the flour and over low heat whisk constantly for about a minute.
-
9
Start adding the hot milk mixture into this mixture a little bit at a time.
-
10
When you add the first bit of milk, the mixture may clump and you will think you have gone wrong.
-
11
You havent.
-
12
Just keep adding the milk and stirring after each addition until the milk is all added and you have a thick white sauce.
-
13
Add pepper and nutmeg, taste and adjust seasonings if needed.
-
14
Take off heat and set aside.
-
15
Prepare mushrooms: Discard the stems of the portobellos and/or trim stems of creminis.
-
16
Slice mushrooms into 1/4 inch thick pieces.
-
17
Heat half of the remaining butter in a frying pan or saucepan, and saute half of the mushrooms with a pinch of salt for about 5 minutes, until they are releasing some liquid.
-
18
Remove those mushrooms into a bowl and repeat process with the remaining butter and remaining mushrooms.
-
19
To assemble: Spread some sauce in the bottom of your baking dish, followed by a layer of noodles.
-
20
Then spread 1/4 of remaining sauce on top of noodles, followed by 1/3 of the mushrooms, and 1/4 cup of Parmesan cheese.
-
21
Repeat this layering sequence twice.
-
22
For the final layer, top the noodles with remaining white sauce and another 1/4-1/3 cup Parmesan cheese.
-
23
Bake for 45 minutes, until top is browned and sauce is bubbling.
-
24
If you can resist digging in right away, let sit at room temperature for 10-15 minutes.
-
25
We did not let it rest and it was still excellent.
