  1. This soup is fantastic! I scaled it down to 4 servings and I wish I had made more. I followed the recipe as best I could but I made at the last minute and did not have fresh parsley so I used dried parsley. I added the dried parsley with the broth and added 1/4 - Read more ...
  2. I've made this soup a couple of times and it's always been completely delicious. I served it at thanksgiving this year and it was a rave.
  3. This was a very good recipe and I will be making it again. It was especially easy.
  4. Worth way more than 5 stars. I'm the only one in my house who eats mushrooms (I married a heathen!) but I make up for the lack by liking them A LOT and this recipe satisfies my cravings. When I'm eating a mushroom soup I want mushroom flavor not 11 herbs and spices and this - Read more ...
  5. I scaled down to four servings. I added a small clove of crushed garlic to the onions and mushroom mixture.

  9. Used AR's "change servings" feature and scaled this down to 4 servings. Was a little shy on the milk, so I added a bit of heavy cream (maybe 1/4 cup) I had left in the fridge. Used baby bella mushrooms (1 lb), and added a little more flour to reach the mushroom soup consistency I - Read more ...
  10. I am obsessed with this soup! I made it at my restaurant and people went nutso for it! Simple ingredients turned into something magnificent. Unless you are feeding a hungry restaurant crowd, I would suggest scaling the recipe back because it makes a large quanirity as written.
