Flank steak is one of my favorite cuts of steak, but I never seem to have any ideas for how to prepare it. I came across a recipe for Flank Steak with Caramelized Onions and Balsamic Glaze that's been in my online cookbook forever. Love caramelized onions, love balsamic, how could we go wrong?
This recipe calls for a simple balsamic reduction. I've reduced balsamic before, but it's been a while and I had forgotten how wonderfully thick and syrupy it gets with no real work other than letting it boil. The onions and balsamic complement the steak wonderfully.....delicious!
This recipe might be best kept for cooler grilling days as it calls for reducing the balsamic and caramelizing the onions for about a 1/2 hour.
