Total Time
Prep 10 mins

I marinated the London Broil over night. Served with my Caramelized onions Caramelized Onions but feel free to make your own or serve without. This tough piece of meat is very tender cooked and sliced this way. This is not to be overcooked. Hope you have good will power because this you will want to keep on eating.

Rita, putting this marinade together was like making a secret potion, very exciting and I wondered how it would taste. Let me tell you it was the most outstanding marinade I have ever tasted, my family will back me up on that. Thanks for posting, I have enjoyed many of your recipes!

Loved this Rita! Omitted the Horseradish as we do not get it here. But stuck to the rest of the recipe including the caramalised onion.Cooked on the stove top in a griddle though.Used what we call beef undercut(tender and cooks very fast) here as I do not know what is London broil. Will be making this again. Thank you.
