01 - In a large bowl, combine the 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 incorporated.
02 - Shape the mixture into 8 evenly sized patties, approximately 1/2 inch thick for uniform cooking.
03 - Lightly coat each patty in flour, shaking off any excess to ensure even crisping.
04 - Heat vegetable oil in a large skillet over medium heat until shimmering.
05 - Fry the croquettes in batches for 3 to 4 minutes per side, until golden brown and crisp. Transfer to a paper towel-lined plate to drain excess oil.
06 - Serve hot with remoulade, tartar sauce, or your preferred dipping sauce.
