In a shallow dish whisk the eggs with the milk, set aside.
In a small bowl, combine smoked paprika, with cayenne, garlic powder, black pepper, and salt.
In a different dish, combine the flour with milk powder, baking powder, and the spice mix.
To create a shaggy crust/crumbles, add 2 tablespoons of the egg milk mixture to the dry flour mixture, and rub with your fingertips until the flour mixture is coarse.
Preheat the oil in a Dutch oven or a deep fryer to 350°F (180°C) degrees.
To coat the chicken, dip each chicken cutlet in the egg milk mixture, and allow any excess to drip off then dredge in the flour mixture and press down firmly for the flour mixture to adhere.
Gently shake off any excess and slowly drop in hot oil. Repeat with the remaining chicken cutlets, and fry for 4 minutes. The chicken is ready when the internal temperature registers at 165°F (74°C) degrees. If shallow frying, fry for 3-4 minutes on each side and check the internal temperature with an instant read thermometer.
Transfer to a wire rack and top with cheese (American, Colby Jack, or Pepper Jack).
To assemble, toast the hamburger buns, spread the chick-fil-a sauce on both sides of the bun. Top with pickles, lettuce, 2 tomato slices, fried chicken, and cheese. Close sandwich and serve with waffle potato fries.
Brine the chicken. If time allows, I always recommend brining the chicken so it’s juicier and thicker. Let chicken cutlets sit in 1 quart of cold water, ¼ cup of kosher salt, and ¼ cup of sugar mixture for 30 minutes to an hour.
Add more or less spice. To make it a spicy deluxe, just add more cayenne. However, if you are making it for kiddos, you can just skip the cayenne.
Fry right after breading. If you let the breaded chicken sit for long, the breading will become soggy and won’t crisp up very well.
Always deep fry it. To make it as close as possible to Chick-Fil-A, you will want to deep fry the chicken. If you want to shallow fry the chicken, it will still work but won't be super crispy. You can also Air Fry the chicken like I did in my Air Fryer nashville hot chicken recipe.
Keep warm in the oven. While frying other cutlets, place done cutlets on a wire rack and place in the oven to keep warm. But make sure you’re using an ovenproof wire rack that does not melt in the oven.
Add more deliciousness. To make this sandwich even tastier, add bacon, extra cheese, or even 2 cutlets of chicken per sandwich!
