Place chicken breasts between sheets of plastic wrap and pound to an even 1/2-inch thickness.
Submerge chicken in dill pickle juice in a sealed container; refrigerate for 30 minutes.
Prepare three shallow bowls: one with flour, salt, and pepper; one with beaten eggs; and one with a mixture of panko, parmesan, dried dill, garlic powder, and onion powder.
Remove chicken from brine and pat dry with paper towels.
Dredge each piece of chicken in flour, then dip into egg wash, and finally press firmly into the panko-parmesan mixture.
Heat oil in a large skillet over medium-high heat.
Fry chicken for 4 to 5 minutes per side until the internal temperature reaches 165 degrees Fahrenheit.
Transfer to a wire rack to drain for 2 minutes before serving.
