Step 1: Season the Chicken - In a large bowl, combine the ground chicken, salt, garlic powder, and onion powder. Use clean hands to gently mix until everything is evenly combined. Do not overwork it or the patties can become dense.
Step 2: Shape the Patties - Divide the mixture into four equal portions and shape them into oblong patties. This shape is key if you want that authentic look and bite. Place the patties on a parchment lined tray.
Step 3: Freeze for Structure - Place the tray in the freezer for at least one hour. This step helps the patties hold their shape during breading and frying and keeps them juicy.
Step 4: Set Up the Dredging Station - Place the flour in one shallow dish. In another dish whisk together the eggs and water. In a third dish mix the breadcrumbs, black pepper, and paprika.
Step 5: Heat the Oil - In a large deep skillet, heat about one inch of oil over medium high heat. The oil should be hot but not smoking. Around 350°F is ideal.
Step 6: Bread the Patties - Remove the patties from the freezer. Dredge each one in flour, then dip into the egg mixture, and finally coat thoroughly in the breadcrumb mixture.
Step 7: Fry Until Golden - Working two patties at a time, carefully place them into the hot oil. Fry for about two to three minutes per side, flipping once, until golden brown and cooked through. The internal temperature should reach 165°F.
Step 8: Drain and Rest - Transfer the cooked patties to a wire rack to drain. This keeps the coating crispy instead of soggy.
Step 9: Toast the Buns - In a clean skillet over medium heat, melt the butter. Place the buns cut side down and toast until lightly golden.
Step 10: Assemble the Sandwiches - Spread mayonnaise on the buns, add a crispy chicken patty, and top with shredded lettuce. Close the bun and serve immediately.
