Sirloin steaks are a type of beef steak that is cut from the back end of the animal. They are typically tender, flavorful, and well marbled with fat. The best sirloin steaks come from cattle that have been raised on grassland rather than corn feedlots. Grass-fed cows produce meat that is higher in Omega 3s and lower in saturated fats. Sirloin steaks are one of the most popular cuts of beef in America and can be found in many grocery stores across the country. However, there are actually two different types of sirloins: inside or outside. The difference between these is significant because they both have their own distinct flavor profile that makes them perfect for different dishes. Inside sirloins are very lean with lots of marbling while outside sirloins are more fatty which means it has less tenderness but also more flavor!
