The Flat Iron Steak’s Origin
Grilled Flat Iron with Spanish Spices recipe uses a steak that wasn’t around 20 years ago. Believe it or not, the name for the Flat Iron wasn’t around prior to 1998. The National Cattlemen’s Beef Association developed this cut from a larger shoulder. They partnered with two universities to see if cheaper parts of beef, such as the chuck or round, could be cut into usable steaks.
The flat iron cut was discovered through trial and error. Eventually leading to find, where seams in the beef would be best utilized to make butchering worth the effort. Flat Iron steaks are cut from the top blade which weighs about 3 lbs and when broken down into steaks yields 4 steaks between 8-12 ounces. Usually cut into rectangle shape about 10-12″ long and about 1″ thick.

Recommended Cooking Methods

Marinating the beef is a good option too. The meat has a lower fat content and marinating can help impart flavors into the beef.
Stir frying sliced flank steak and searing in a pan over high heat would produce good results also. Pairing the seared beef with some onions, bell peppers and carrots then saucing with some teriyaki sauce or mongolian sauce would be delicious.
Pair Flat Iron with Romesco
Spanish Romesco Sauce
Because of Moorish Empire influence for 800 years, Spain and Portugal were introduced to many spices they still use today. Romesco was one recipe that utilized some of the spices brought through trade routes.
Making this Romesco sauce is easy to make. Roast some peppers & almonds, make some toast and puree in a food processor. The sauce stores for up to a week and can be used on many meats. The sweet roasted peppers with the tomato and Spanish spices will compliment the spiced steak.
