Secret Recipe Club: Flat Iron Steak with Blue Cheese Sauce

For this month's Secret Recipe Club assignment, I was paired up with Family, Friends, and Food.  I was immediately drawn to her recipe for steak with blue cheese sauce, because I love good steak and I really love blue cheese.  The sauce even sounded good enough that I convinced my mom to try it, despite the fact that she's a little skeptical of red meat!  The blue cheese sauce seriously could not be easier (three ingredients shaken up in a jar), but it's absolutely delicious and pairs perfectly with steak.  We served the steak with peppers and onions, as well as red potatoes sauteed in butter and olive oil.  The sauce was also great with the potatoes, and I think it would be fantastic on a salad or a burger, too.  Plus, I love having a recipe to use up little bits of leftover buttermilk - it seems I always have small amounts of things like buttermilk and cream in the fridge that aren't enough to bake with.  This sauce is the perfect solution!

Flat Iron Steak with Blue Cheese Sauce (adapted from Family, Friends, and Food, original recipe here)
Serves 3

1/3 cup crumbled blue cheese
1/3 cup buttermilk
Generous dash of Worcestershire sauce
1 pound flat iron steak
Salt and pepper
Canola or vegetable oil

1. Put the blue cheese, buttermilk, and Worcestershire sauce in a jar.  Tightly screw on the lid and shake until everything is combined.  Taste, and add more Worcestershire sauce if needed.  Set aside.
2. Season the steak all over with salt and pepper. Heat the oil in a large pan, and when the oil is hot, carefully add the steak.  Cook to your desired level of doneness, and then remove to a cutting board and cover with foil.  Let rest for about 5 minutes, and then thinly slice the steak against the grain.
3. Serve the steak with the blue cheese sauce.
