This was wonderful!! DH just loved it. I did add more cream potatoes than called for cause I felt after I got it in the casserole dish it wasn't enough to cover the mixture, so I made up some instant potatoes and it was perfect. I also used real mushrooms (thats what I had on hand)and I added 2Tbs. chopped onion. I also used 1c. of beef gravy from a jar(this also is what I had on hand)instead of the dry beef gravy. I had a bit of mess in the oven from the overflow but it was well worth it since it pleased the "Man of the house"!! Thanks so much for sharing this delicious recipe.
