01 - Combine sour cream, mayonnaise, chopped dill, chives, lemon juice, Dijon mustard, garlic powder, salt, and pepper in a medium bowl. Whisk until smooth, then cover and refrigerate until ready to serve.
02 - Arrange three shallow bowls. Place flour in the first bowl. Whisk the eggs in the second bowl. In the third bowl, combine panko breadcrumbs, grated Parmesan cheese, chopped dill, garlic powder, onion powder, and black pepper.
03 - Dredge each dill pickle slice in flour, ensuring it's fully coated. Next, dip it into the beaten egg, allowing excess to drip off. Finally, press the pickle slice into the breadcrumb mixture, coating all sides thoroughly. Repeat this process for all pickle slices.
04 - In a large, heavy skillet or a deep fryer, heat approximately 1 inch of vegetable oil to 350°F (175°C).
05 - Carefully place the breaded pickles into the hot oil in batches, ensuring not to overcrowd the pan. Fry for about 2 minutes per side, turning once, until they achieve a golden-brown and crispy texture.
06 - Using a slotted spoon, remove the fried pickles from the oil and place them on a plate lined with paper towels to drain excess oil. Serve immediately while warm with the chilled tangy dill dip.
