Fill a large enameled Dutch oven or deep fryer with a 50/50 blend of vegetable oil and the animal fat of your choice, about 4 inches deep. Heat to 350°F. If you do not have animal fat, you can just use vegetable oil.
In a large bowl, whisk 8 cups of all-purpose flour with the granulated garlic and black pepper, and set aside.
In a separate large bowl, whisk the beer with baking powder and 8 cups of seasoned flour until smooth.
Season the steak all over with the Cajun seasoning, then pound thin. Working one at a time, dredge each steak in the flour, shaking off any excess. Then dip the steak in the beer batter, letting any excess drip back into the bowl. Then dredge the steak once more in the flour. Transfer to a plate and repeat with the remaining steaks. Fry the chicken-fried steak in the hot oil until golden brown, 5 to 8 minutes.
Serve smothered in black peppered gravy with the vegetables of your choice on the side.
At Lambeau’s America, this dish is served with black pepper gravy, bacon green beans, and roasted red potatoes.
