In a shallow bowl, whisk together the milk and egg.
In another shallow bowl, combine the flour, crushed saltine crackers, seasoned salt, onion powder, garlic powder, and Montreal steak seasoning.
Dip one cube steak into the egg mixture, allowing any excess to drip off.
Coat the steak thoroughly in the seasoned flour mixture, pressing gently so the coating sticks well.
Repeat with the remaining steaks.
Heat the vegetable oil in a large skillet over medium-high heat.
Carefully place the coated steaks into the hot skillet.
Cook the Country Fried Steak Recipe for about 4 minutes per side, or until the coating is crisp and golden brown and the internal temperature reaches 160°F (70°C).
