It wasn’t widely available until the late 1990s, when researchers at the University of Nebraska and the University of Florida, working with the National Cattlemen’s Beef Association, identified it as a potentially valuable cut from the chuck. Previously, the top blade muscle was often used for ground beef or less desirable cuts due to a tough line of connective tissue running through it. By developing a specific butchering technique to remove this tissue, the Flat Iron Steak was born, offering a tender and flavorful steak from a previously underutilized part of the animal. Read More Nutritional Information on Beef Flat Iron Steak Beef Flat Iron Steak is a relatively lean and nutritious cut of beef. It’s an excellent source of high-quality protein, essential for building and maintaining muscle mass. It also provides important minerals like iron, crucial for red blood cell production, and zinc, which supports immune function. While it’s not as lean as some cuts, like eye of round, it’s still a relatively healthy option, especially when compared to heavily marbled steaks. The specific nutritional content will vary, but it’s generally a good source of protein and essential nutrients. Read More Read More: Culinary History of Beef Flat Iron Steak The “Invisible” Steak: Early Days and the Chuck Underblade For decades, the muscle that would become the flat iron steak was largely unknown to consumers and even to many butchers. It resided within the chuck primal, specifically within the infraspinatus muscle of the chuck underblade. The chuck, known for its rich flavor but also for its toughness, was typically used for pot roasts, stews, and ground beef. The problem wasn’t the muscle itself; it was the thick layer of tough connective tissue (silver skin and fascia) that ran through the middle of it. This connective tissue made the entire muscle unsuitable for quick-cooking methods like grilling or pan-searing. As a result: Discarded or Ground: The chuck underblade, including the infraspinatus, was often either discarded as trim or ground into hamburger. The labor-intensive process of removing the connective tissue was not considered economically viable. Lack of Recognition: Even if butchers were aware of the muscle’s potential, the difficulty in preparing it and the lack of consumer demand meant it remained largely hidden. Regional Variations: In some areas, particularly in parts of Europe, the muscle might have been used in specific regional dishes, but it lacked widespread recognition or a consistent name.

Regional Variations: In some areas, particularly in parts of Europe, the muscle might have been used in specific regional dishes, but it lacked widespread recognition or a consistent name. The Breakthrough: Research and Innovation The transformation of this overlooked muscle into the flat iron steak began in the late 1990s and early 2000s, thanks to a collaborative research project between the University of Nebraska-Lincoln and the University of Florida. This project, funded by the Cattlemen’s Beef Board checkoff program, aimed to identify and develop new, value-added cuts of beef from underutilized muscles. The Muscle Profiling Study: Researchers systematically analyzed various muscles from the beef carcass, evaluating their tenderness, flavor, and overall culinary potential. Identifying the Infraspinatus: The infraspinatus muscle within the chuck underblade stood out for its surprising tenderness and flavor, despite the presence of the connective tissue. Developing a New Butchery Technique: The key breakthrough was developing a butchery technique that could efficiently remove the thick connective tissue running through the infraspinatus. This involved carefully separating the muscle into two flat, rectangular steaks, leaving the connective tissue intact. The “Flat Iron” Name: The resulting steaks, resembling old-fashioned flat irons, were given the name “flat iron steak,” a moniker that was both descriptive and appealing.
