Made exactly as directed and just 5 hours in the crockpot on low. This came out almost as dry as jerky. I don't know what I could have done wrong. I'm not joking - even the dog didn't like it. Sorry for the bad review but this was a total waste of money.
This was great! Used the exact recipe with no changes and it was delicious. I thickened the gravy with cornstarch and water, served with mashed potatoes and a veg. Thanks Rotty!
I love that this can be a make-ahead dish (but I didn't wait). And I love that this is a crock pot dish, so it was perfect for a Labor day meal with triple-digit temperatures outside. The only thing I did differently was to keep the mushrooms aside, and I used some of the pan juices to make a mushroom saute to serve over the sliced sirloin: it made a nice presentation. The flavors all mingled perfectly in the crock pot, and it was a rich flavor, not too sweet, salty, tangy or "herby." I think the marinade would also do well for the grill if given a chance to sit with the meat for a few hours. Well done, Rottmom! We enjoyed this very much. Made for PAC, Fall 09
