  1. Preheat oven to 350 degrees F (175 degrees C). Lightly grease a 9x13 inch baking dish.
  2. Bring a large pot of lightly salted water to a boil. Place pasta in the pot, cook for 8 to 10 minutes, until al dente, and drain.
  3. Heat the oil in a saucepan over medium heat. Stir in the mushrooms, cook 1 minute, and set aside. Melt margarine in the saucepan. Mix in flour, garlic, and basil. Gradually mix in milk until thickened. Stir in 1 cup cheese until melted. Remove saucepan from heat, and mix in cooked pasta, mushrooms, spinach, and soy sauce. Transfer to the prepared baking dish, and top with remaining cheese.
  4. Bake 20 minutes in the preheated oven, until bubbly and lightly brown.

5 stars for something different and interesting that my boyfriend will eat! I used low fat mozzerella and it was delicious. I am going to double the spinach next time too. Instead of dried ba...

Made as written, I give this 3.5 stars - I didn't think it was nearly cheesy, and the sauce was pretty thin and watery. However, I added more cheese - a combination of mozzerella, Swiss and extr...

Excellent dish! My boyfriend said he could eat it every day and not get tired of it. I made a few minor changes - used some random pasta I had (not penne), replaced the soy sauce with some salt ...

After reading all of the reviews on AR, I decided to do the following: Sautee the mushrooms till tender; let weep and throw out the extra liquid... I'll keep it in next time; with the added ch...
