Flank Steak With Horseradish Sauce

READY IN: 8hrs 35mins
Recipe by Chris from Kansas

The low-fat horseradish sauce is a great compliment to this tender seasoned steak. We love this! Cook time includes 8 hours for marinading.

Love the horseradish sauce! Delicious! I think I let my steak marinade a bit too long, at 10 hours. The mustard taste was a bit strong, but I think that was my fault for letting it marinate too long. I will try it again with either a bit less mustard or the correct timing! Thanks for sharing!
