I've made this twice now. The first time I followed the recipe to the letter and found it decent but knew the recipe had potential with a little tweaking. The second time, I did the following things to snaz it up: seasoned the beef with kosher salt, fresh cracked pepper, and garlic powder, browned the beef before adding it to the slow cooker, sauted 2 cups sliced mixed mushrooms and 1 onion sliced in the beef drippings before adding them to the slow cooker, deglazed the pan with 1/2 cup of red wine and added that also to the slow cooker, used 1/2 unsalted and 1/2 salted butter and then used low-salt soup mix to avoid all the saltiness. I serve it over either egg noodles or mashed potatoes. It is now much requested in my house.


5+++++!! Great flavor - this is the second time I've made it and the first time was exactly as written and it was great that way. After reading other reviews I decided to do a bit of tampering - browning beef first, adding mushrooms, garlic and onions and a bit of red wine. Oh my! It's even better. Also towards the end I added a packet of beef gravy to thicken it up. Was lovely over mashed potatoes. Will be making this again...and again...and... : )

What a FANTASTIC treat!! Made the house smell divine!!! I used a 1.5 lb London broil (cut into cubes) and 3/4 cup butter, added a 4-oz can of unsalted mushroom pieces, and one finely chopped leek, and the one envelope of dry onion soup mix - like the recipe states. Served over white rice and with minted peas on the side. This was the most tender beef I've ever had!!!
