Set up a dredging station using 3 shallow bowls.
In the first bowl, pour in ¾ cup flour.
In the second shallow bowl, whisk buttermilk and egg together.
In the last bowl, whisk remaining flour, bread crumbs, Cajun seasoning, garlic salt, and red pepper flakes together.
Dip each strip of steak into the flour mixture, then buttermilk and mixture, and finally in the flour and bread crumb mixture, making sure to coat each strip at each station.
Heat oil in large frying pan over medium high heat.
Add each piece into hot oil, 6-8 at a time, and cook a couple minutes on each side.
Remove and place on plate lined with paper towels.
Serve hot with your favorite dipping sauce.
