My family loved this. I love the rich flavor the tomato soup adds. Here's what I did the second time to make it perfect: -Used London Broil, not flank steak. -Add 1 tbl worcestershire -Add 1 tbl red wine vinegar -Mix all 3 soups together first. -Added some carrots and potatoes - To keep them from changing the flavor of the sauce and soaking most of it up, I place the veggies in some aluminum foil, fold the sides up to make a little boat and sit on top of the meat - I read this trick in a cooking magazine.


I had a cut of london broil in my freezer, and I have been eyeing this recipe for some time. Grilling the meat was out of the question since it is February and the dead of winter here. And that is the only way I have ever made london broil. I was attracted to this recipe because of the different ingredients used. So I figured I'd give this a try. I used low sodium tomato soup and low fat cream of mushroom soup, 2 splashes of Worcester sauce, 1 splash of wine as reviewers suggested. Also added only 1/3 of the onion soup mix and sliced baby portabellas, a chopped onion and carrots. The appearance, texture and aroma was not appetizing. My husband came in after it had been on for 7 hours and said "gee usually when I come home and your cooking it smells so GOOD what happened"? Yikes! I made mashed potatos as so many others suggested to serve this with and reluctantly we dug in. It was EXCELLENT. Wow. We were both so impressed and decided to add this to our regular rotation. The meat comes out very much like pot roast with a steak flavor, and the gravy, no matter what you think about it as it's cooking, it comes out so flavorful and tasty you will be tempted to just dunk some bread in it. Great recipe, and I recommend listen to others here and reducing the sodium content, adding veggies, it still is excellent.


First of all I need to thank you for the easiest, tastiest crockpot dish ever. I actually planned to make it exactly as written but realized I opened a can of cream of chicken soup instead of cream of mushroom soup by accident. I then just mixed the soups and dry onion soup mix together and poured it over the london broil, turned the meat a few times to coat it, turned the crockpot on low and ran out the door for work. I planned to be home in 8 hours or so, but got stuck at the office and didn't get home for 11 hours. I thought I was going to have a mess and no dinner. Instead I was greated to the most melt in your mouth london broil ever. The gravy was fabulous! Next time I will double the gravy so I can have leftover!
