This was a disaster. I cooked the roast in the slow cooker for several hours according to the recipe, then decided to follow the tip of adding a can of mushroom soup. After I had added it, I sampled it and it tasted like mould. I thought perhaps the package of onion soup had somehow gone bad, so I threw out the gravy, rinsed off the roast and made the gravy again, this time with beef stock instead of onion soup. Same mouldy taste. I used a generic blue brand of cola from a big supermarket which I sampled before adding, and it was fine, so I'm thinking there was some kind of weird reaction between it and the mushroom soup. The roast beef itself was very tender though. I will probably try this again, but without the mushroom soup.
I made this dish and it was very delicious
This was awesome,I added the soup too and also a cup of beef broth!!!!!!!
This recipe was quick and easy to prepare. I used the sliced potatoes and cut mini-carrots in half in the bottom of the crock pot. The combination of slow cooking and cola (as tenderizer) made the meat melt in your mouth! My family Loved it!
This is outstanding, for sure! The only changes I made were to sear my rump roast and leave it whole, not cubed, in order to slice. I added about 1/3 can of left-over cream of celery soup to the sauce for gravy. YUM!
I've made a recipe similar to this and it's great. Mix a can of cream of mushroom soup with the onion soup and cola and pour over the roast. Makes a delicious gravy.
