You’ll find the flat iron listed as a “butcher’s cut” since it’s long been a favorite of butchers and beef experts. Snake River Farms flat iron steaks are highly marbled for a large helping of juicy flavor. A surprising fact, the flat iron is the second most tender steak after the filet mignon. The natural tenderness, combined with the buttery aroma and flavor of American Wagyu, makes this one of our favorite steaks. 

Each American Wagyu flat iron is generous in size and serves two, three or more people. Delicious with simple seasonings, the flat iron also works wonderfully with your favorite marinade.

Cooking Tips

The flat iron steak is best cooked medium rare to medium to maximize its tenderness and to allow the generous marbling to melt and become juicy.

Grilling, pan searing and the steakhouse method are good techniques for cooking the flat iron steak.

There is a strip of connective tissue that runs through part of the steak. It’s easy to spot, so cut around it after cooking.

The flat iron is a thin, rectangular cut and can be used in recipes that call for flank or skirt steak. This steak can be prepared whole or cut into strips for stir frying, tacos or fajitas.

For those who prefer a well done steak, the flat iron holds up well to temperatures of 160°F and above.

Beef Grading

Snake River Farms beef grades start at USDA Prime, the top grade on the USDA scale. The majority of SRF beef is marbled well beyond this level. To grade SRF, we use a 12-point Beef Marbling Score (BMS), which measures marbling that exceeds the USDA scale.

SRF Silver® - BMS of 4 to 5. Marbling comparable to USDA Prime. 

SRF Black® - BMS of 6 to 8. Significantly more marbling than USDA Prime.   

SRF Gold® - BMS of 9 to 10. Dramatically more marbling than USDA Prime. 

SRF Gold Plus™ - BMS of 11 to 12. The highest marbling available from Snake River Farms.
