Prepare the Meat: Pound cube steaks to even thickness (¼ inch). Season both sides with salt, pepper, and garlic powder.
Set Up Breading Stations: In three shallow dishes, place seasoned flour in one, whisked eggs with buttermilk in another, and more seasoned flour in the third.
Double Dredge: Coat each steak in flour, dip in egg wash, then dredge again in flour. Let the coated steaks rest for 5 minutes.
Heat Oil: Heat vegetable oil in a cast-iron skillet to 350°F (175°C). Test readiness by sprinkling a pinch of flour — it should sizzle immediately.
Fry the Steaks: Carefully place the steaks in hot oil. Fry 3–4 minutes per side, or until golden brown. Drain on a wire rack or paper towels.
Make the Gravy: Using leftover drippings, whisk in flour to make a roux. Gradually add milk, stirring until thickened. Season with salt and pepper.
Serve: Plate the crispy chicken fried steak, pour creamy white gravy over the top, and serve immediately with classic sides.
