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