01 - Gently combine 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 in a large bowl. Mix until just combined—do not overmix to avoid breaking up the crab.
02 - Shape mixture into 8 equal patties, about 1/2 inch thick. Add additional panko if mixture is too loose.
03 - Place extra panko breadcrumbs on a plate. Gently coat each crab cake in panko, pressing lightly to adhere. Transfer to a tray and refrigerate for 15–20 minutes to set.
04 - Mix mayonnaise, dill pickles, capers, lemon juice, Dijon mustard, and dill or parsley in a small bowl. Season with salt and pepper to taste. Refrigerate until serving.
05 - Heat vegetable oil in a large skillet over medium heat. Fry crab cakes in batches for 3–4 minutes per side until golden brown and cooked through. Drain on paper towels.
06 - Serve hot with tartar sauce and lemon wedges if desired.
