Easy Flat Iron Steak Recipe
It snowed this week and while you may think that’s nothing, to me it was Mother Nature (or the Alberta weather) letting us know that she ain’t done with us yet. Oh, we may have had the mildest winter that I can ever remember, with very little snow and days so nice that I’ve lived in a sweater instead of a winter coat for weeks upon end, but it’s not over until Mother Nature says so. And she usually says so right after she dumps a large amount of snow on us for the May long weekend.
We’re still quite a few weeks away from May long weekend, so as much as I had enjoyed my BBQ (and the snow-free deck that it sits on) it’s STILL crock pot weather. It’s still the comforting, hot-food-that-cooks-all-day time of year, so I thought I’d try crock pot flat iron steak.
What is Flat Iron Steak?
Flat iron steak is a cut of beef that comes right off of the shoulder-blade area of the cow. This thin strip of steak is a tender, lovely piece of beef that I prefer to cook low and slow, contrary to popular use. The flat iron has come back in style lately, with a lot of restaurants serving it up along with flank and hanger steaks. Sadly, it’s very hard to get one properly cooked and sliced. I am getting cranky in my old age and to be honest, there are very few cuts of steak that I enjoy as a grilled item anymore. I know. Forty is when the descent into senior-ism starts.
However I am completely serious, all jokes aside. Trendy or not, I’ll take a tenderloin for the BBQ and skip everything else. That sounds really hoity-toity (have I ever used that phrase here? Well, it’s about time I did) but for the very few times we that actually eat steak, it’s not that bad. Go for small portioned, good quality steak for grilling every time and you will be a happy griller.
Flat iron steak does not have to be fancy. It doesn’t always need a chimichurri – although it really is my favorite way to eat flank steak- and it doesn’t need 11 herbs and spices.
I stopped by ACME Meat Market here in Edmonton, the perfect place to pick up cuts of meat that you won’t find at your regular grocery store. You can see with the meat how it will be better when you cook it low and slow. See all that fat marbling?
How to Cook Flat Iron Steak
This was the simplest recipe that I could possibly think of and it is scrumptious. Crock pot Flat Iron steak is SO the way to go!It will dissolve with the right amount of cooking time, leaving you with meat reminiscent of short ribs. Falls apart and into your mouth. Low and slow is meant for the slow cooker, and so are large chunks of onion and massive portobello mushroom along with the flat iron steak.
- Place the ingredients into the crock pot in the correct order
- Cook the flat iron steak low and slow for hours
- Serve and enjoy
The flat iron steak cooks the best when it is placed under the vegetables and cooks with lots of liquid from the beef broth and the vegetables on top that are releasing liquid as well.
This right here?
It’s such a comforting dish, with simple yet delicious flavours, which is my favorite kind of meal. Prep it, set it, let it cook all day and then come home to a hot, delicious meal ready to go.
Happy Cooking everyone! How’s the weather been where you live? How was your winter?
