How Do You Cut A Sirloin Steak For Fajitas?
First, you want to freeze the sirloin steak for 30-45 minutes to help it firm up and make it easier to slice. Once it has firmed up, cut the steak against the grain into thin strips that are about 1/4-inch thick. This will help ensure that the fajitas are tender and easy to chew. You can also season the steak with fajita seasoning or your preferred spices before cooking.
