This recipe turned out to be very good, I followed the directions as followed but added mushrooms and 2 tsp of garlic and allowed for them to sautee a little with the onions. Afterwords I added my already cooked shrimp to the rest of the mixture and let them simmer for awhile. The sauce was actually the most time consuming part of the whole recipe. The cream never seemed to really come to a boil but it was still fine. I cooked the sauce separately and added the whole cup of chopped parsley, and the instructed amount of everything else to it. I substituted the white pepper with Cajun seasoning. Once done I poured the sauce in with everything else and let it all cool so the sauce could thicken. Don't forget your cheese that's the finishing touch. I used the Parmesan but also added cheddar and mozzarella cheeses instead of Swiss. The only thing I wish I had done differently was add cornstarch so that my sauce would have been thicker.Otherwise this dish had a nice taste with alot of flavor. Will do again! Thanks
