01 - Pat fish fillets completely dry with paper towels. Season both sides generously with salt and pepper.
02 - Arrange three shallow bowls: place flour in the first, whisk eggs with milk in the second, and combine breadcrumbs with paprika and garlic powder in the third.
03 - Dredge each fillet in flour, shaking off excess. Dip into egg mixture, allowing excess to drip off, then press firmly into breadcrumb mixture to coat completely.
04 - Pour 1/2 inch vegetable oil into a large skillet. Heat over medium-high heat until oil shimmers and reaches 350°F.
05 - Fry fish in batches, cooking 3-4 minutes per side until golden brown and cooked through. Transfer to paper towel-lined plate to drain excess oil.
06 - Combine mayonnaise, chopped pickles, capers, lemon juice, Dijon mustard, and parsley in a mixing bowl. Stir thoroughly until well blended. Season with salt and pepper to taste.
07 - Arrange hot fish fillets on serving plates. Serve immediately with tartar sauce and fresh lemon wedges.
