01 - In a large bowl, gently combine the crab meat, red bell pepper, celery, green onions, eggs, mayonnaise, Dijon mustard, lemon juice, Worcestershire sauce, Cajun seasoning, smoked paprika, salt, black pepper, panko breadcrumbs, and parsley. Mix until just combined—do not overmix to avoid breaking up the crab.
02 - Shape the mixture into 8 equal patties, about 1/2 inch thick. If the mixture is too loose, add a bit more panko.
03 - Place extra panko breadcrumbs on a plate. Gently coat each crab cake in panko, pressing lightly to adhere. Transfer to a tray and chill in the refrigerator for 15–20 minutes to help them set.
04 - In a small bowl, mix together mayonnaise, dill pickles, capers, lemon juice, Dijon mustard, and dill or parsley. Season with salt and pepper to taste. Refrigerate until ready to serve.
05 - Heat vegetable oil in a large skillet over medium heat. Fry the crab cakes in batches, 3–4 minutes per side, until golden brown and cooked through. Drain on paper towels.
06 - Serve hot, accompanied by tartar sauce and lemon wedges if desired.
