I agree this is one of the fastest ways to impress people I've discovered. I've tried this recipe with store-bought Alfredo sauce before, and we found it way too sweet--mind you, it was because of the paticular sauce we chose. A quick suggestion if you don't have the ready-made sauce on hand: saute 2-3 cloves minced garlic in some butter, add the mushrooms and saute for 2 or 3 minutes, add 1 tablespoon of flour to 2 cups milk, then add to mushrooms, simmer until thick and then add 1/3 cup parmesan cheese -- voila! A low fat alfredo with delicious mushroom taste!  -  01 Sep 2001  (Review from Allrecipes USA and Canada)

My husband and I both loved this recipe! Don't forget to scrape the "gills" out from the underside of the mushroom, that way the sauce won't turn the purple/brown color some people complained about. I added yellow bell pepper, zucchini, broccoli, cherry tomatoes and carrots as well. Then instead of mixing it all together I just spooned the sauce on top of the noodles and topped it with the mushrooms and veggies. Very delicious and beautiful presentation!  -  12 May 2006  (Review from Allrecipes USA and Canada)

I started hunting around for an alfredo sauce recipe after reading Katya's review. I used the quick and easy alfredo sauce recipe from here(think thats the same one she got from here). It made a huge difference. The dish went from a good one to an excellent one. The sauce definitely transformed it. I also added mozarella to the top after I was done to make it more cheesy. We LOVE this recipe now. I think what I made at home was as good or better than the local restaurant version. I'm glad I have a treadmill.......lotta calories in this one!  -  17 Jun 2004  (Review from Allrecipes USA and Canada)
