Place chicken strips in a glass bowl or resealable bag and pour the dill pickle juice over them; refrigerate and marinate for 30 minutes.
Preheat oven to 400 degrees Fahrenheit (200 degrees Celsius) and line a baking sheet with a wire rack or parchment paper.
Prepare three shallow bowls: one with flour, one with beaten eggs, and one with a mixture of Panko breadcrumbs, Parmesan cheese, dried dill, garlic powder, onion powder, salt, and pepper.
Remove chicken from the brine and pat thoroughly dry with paper towels.
Dredge each chicken strip in the flour, shaking off excess, then dip into the egg wash, and finally press firmly into the Panko-Parmesan mixture until fully coated.
Arrange the breaded chicken on the prepared baking sheet and lightly coat the surface with cooking spray or a drizzle of oil.
Bake for 18 to 20 minutes, flipping once halfway through, until the internal temperature reaches 165 degrees Fahrenheit (74 degrees Celsius) and the exterior is golden brown.
Allow chicken to rest for 3 minutes before serving with additional dill pickle slices or dipping sauce.
