01 - In a large bowl, combine flaked salmon, onion, bell pepper, celery, eggs, breadcrumbs, mayonnaise, Dijon mustard, lemon juice, Worcestershire sauce, garlic powder, smoked paprika, salt, and black pepper. Mix until thoroughly combined and uniform.
02 - Shape the mixture into 8 evenly sized patties, approximately 1/2 inch thick. Press firmly to ensure they hold together during frying.
03 - Lightly coat each patty in flour, shaking off any excess to prevent a heavy coating.
04 - Pour vegetable oil into a large skillet and heat over medium heat until shimmering but not smoking.
05 - Cook croquettes in batches for 3-4 minutes per side until golden brown and crispy. Transfer to a paper towel-lined plate to drain excess oil.
06 - Serve hot with zesty remoulade, tartar sauce, or your preferred dipping sauce.
