Blue Cheese Flat Iron Steak

This is one of my favorite flat iron steak recipes. If you haven't already enjoyed the rich, creamy pairing of blue cheese with your favorite steak, stop reading and get cooking! I take it a step further by folding in a little butter to make the dish even more drool-worthy. —Amanda Martin, Monson, Massachusetts

    Excellent! Easy and delicious! The only thing I changed was the cooking technique, using my tried and true broiling method of 3 minutes per side for 15-18 minutes. The blue cheese butter really compliments the steak. Definitely will be making repeat performances in my house!

    I made sandwiches out of fresh ciabatta bread - oh my goodness they were good and a big hit with my company. The blue cheese butter was so easy to make and the perfect touch.
