Ingredients Nutrition


  1. Preheat oven to 375 degrees.
  2. Bring a large pot of water to a boil with 1 T salt and a splash of oil.
  3. Add the lasagna noodles and cook for 10 minutes, stirring occasionally; drain and set aside.
  4. For the white sauce, bring the milk to a simmer in a saucepan; set aside.
  5. Melt 8 T (1 stick) of the butter in large saucepan.
  6. Add the flour and cook for 1 minute over low heat, stirring constantly with a wooden spoon.
  7. Pour the hot milk into the butter-flour mixture all at once.
  8. Add 1 T salt, the pepper and nutmeg, and cook over medium-low heat, stirring first with the wooden spoon and then with a whisk, for 3-5 minutes, until thick.
  9. Set aside off the heat.
  10. Separate the mushroom stems from the caps and discard the stems.
  11. Slice the caps 1/4-inch thick.
  12. Heat 2 T of oil and 2 T of the butter in a large (12-inch) saute pan.
  13. 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.
  14. If they become too dry, add a little more oil.
  15. Toss occasionally to make sure the mushrooms cook evenly.
  16. Repeat with the remaining mushrooms and set all the mushrooms aside.
  17. To assemble the lasagna, spread some of the sauce in the bottom of an 8x12x2-inch baking dish.
  18. Arrange a layer of noodles on top, then more sauce, then one-third of the mushrooms, and 1/4 cup grated Parmesan cheese.
  19. Repeat two more times, layering noodles, sauce, mushrooms and Parmesan.
  20. Top with a final layer of noodles and sauce, and sprinkle with the remaining Parmesan.
  21. Bake, uncovered, for 45 minutes, or until the top is browned and the sauce is bubbly and hot.
  22. Allow to sit at room temperature for 15 minutes and serve hot.

I added spinach and marinated artichokes in with the mushrooms, so delicious! My mom and dad came for dinner and they were very impressed with this take on lasagna. I will make this again and again, as I just loved it!
