2 lbs mushrooms, chopped (use what you like, I used a mix of buttons and crimini)
3 cloves garlic, crushed
1/2 onion, finely chopped
1/2 cup butter
1/2 cup flour
4 cups whole milk
S & P
1pk lasagna sheets (I used the fresh ones)
Saute the chopped mushrooms, onion, garlic and S & P. Cook down and remove as much liquid as possible (you can reserve this and use it in place of some of the milk in the sauce, just add milk to make 4 cups.)
Melt butter over medium heat in a sauce pan. Add flour and whisk well. Allow to bubble a bit so the flour cooks off. Add 4 cups whole milk and S & P. Bring to a low boil and shut off, stirring frequently.
Place a small amount of sauce (about 1/6th) in the bottom of a 9 x 13" pan. Layer other ingredients:
Bake at 350 for about 45 minutes or until hot. Let rest at least 15 minutes before you cut or it will run everywhere!
