In a large mixing bowl, add mayonnaise, beaten egg, mustard, Worcestershire sauce, hot sauce and Creole seasoning, celery, green onions, minced garlic, parsley and whisk together until fully combined.
Add the crab meat (make sure to check the meat and take out any hard cartilage), bread crumbs (or crackers), pepper and salt. Using a rubber spatula, gently fold mixture together until just combined, being careful not to shred the crab meat any further.
Using your hands, shape into 6-8 crab cakes forming a disk, about ½ cup each (2-2 ½ inches in diameter) and place them on a greased baking pan. Cover and refrigerate for about 1 hour. This will help the cakes to set and not break apart during cooking.
Heat oil in a large nonstick pan or cast iron pan on medium high heat. When the oil is hot, place crab cakes in the pan and cook for about 4-5 minutes on each side or until golden brown flipping cake once. Cook crab cakes in badges to avoid overcrowding the pan.
Serve immediately with tartar sauce and lemon wedges.
