Understanding Salmon Croquettes: History and Basics

Salmon croquettes are a classic dish that combines flaked cooked salmon with binding ingredients, formed into oval or cylindrical shapes, and then fried until golden brown. The word "croquette" comes from the French verb "croquer," which means "to crunch," referring to the crispy exterior that forms during cooking. This dish has been popular in American home cooking for over a century, particularly in Southern and coastal regions where fresh salmon was historically more available.

The basic structure of a salmon croquette includes cooked salmon as the main ingredient, combined with a binder (usually mashed potatoes, breadcrumbs, or a flour-based mixture), seasonings, and sometimes vegetables like diced onions or celery. The mixture is chilled, shaped, coated in breadcrumbs, and then pan-fried or deep-fried. The result is a crispy exterior with a moist, flaky interior that holds together during cooking.

Salmon croquettes offer several nutritional benefits. According to the USDA, a 3-ounce serving of cooked salmon contains approximately 175 calories, 19 grams of protein, and significant amounts of omega-3 fatty acids, which support heart and brain health. The preparation method affects the overall nutritional profile—pan-frying uses less oil than deep-frying, resulting in fewer calories from added fat.

This dish works well for various occasions. You can serve croquettes as an appetizer at dinner parties, as a main course with sides like tartar sauce and vegetables, or even in sandwiches. They can be made ahead and refrigerated for several days before cooking, making them convenient for meal planning. Many home cooks appreciate that this recipe transforms canned salmon (which is more affordable and shelf-stable than fresh salmon) into an elegant dish.

Practical Takeaway: Salmon croquettes are a versatile, nutrient-rich dish that has remained popular for generations. Understanding their basic structure—a salmon mixture bound together, breaded, and fried—provides the foundation for successful homemade versions.

Selecting and Preparing Your Salmon

When making salmon croquettes, you have two primary options: fresh salmon or canned salmon. Fresh salmon offers superior flavor and texture but requires cooking before use. According to the FDA, fresh salmon should be cooked to an internal temperature of 145°F (63°C) to ensure food safety. You can bake, pan-sear, or steam fresh salmon; baking at 400°F (204°C) for 12-15 minutes is a straightforward method for fillets.

Canned salmon is a practical alternative that eliminates cooking time. One 14.75-ounce can of canned salmon typically yields about 1.5 cups of flaked fish, which is sufficient for a batch of 8-12 croquettes. When using canned salmon, drain the liquid thoroughly and check for small bones, which are edible and provide calcium but some people prefer to remove them. Many cooks use the skin that forms during the canning process as part of the mixture, as it adds texture and helps bind ingredients.

The amount of salmon you use affects the croquette's density and flavor intensity. A standard recipe uses 1.5 to 2 cups of flaked cooked salmon. If you use fresh salmon, plan for approximately 12 ounces of raw fillet, which yields roughly 1.5 cups of cooked flaked salmon after cooking and cooling. It's important to flake the salmon into appropriately sized pieces—not so fine that it becomes mushy, but small enough that it distributes evenly throughout the mixture.

Seasoning the salmon before mixing with other ingredients allows the fish flavor to develop more prominently in the final croquette. A simple seasoning of salt, pepper, and a small amount of paprika or Old Bay seasoning (if using the traditional approach) enhances the salmon without overpowering it. Let cooked fresh salmon cool to room temperature before mixing with other ingredients, as hot salmon can make the binding mixture too wet.

Practical Takeaway: Whether using fresh or canned salmon, ensure it's properly cooked, thoroughly drained, and cooled to room temperature. Flake it into medium-sized pieces and season lightly before combining with other ingredients.

Creating the Binding Mixture and Base Ingredients

The binding mixture is what holds your croquettes together during frying. The most common binder is mashed potatoes, which add moisture, creaminess, and help the croquettes hold their shape. For a batch using 1.5 cups of salmon, you'll typically need about 1 cup of mashed potatoes. These can be freshly made or leftover mashed potatoes from another meal. Avoid using potatoes with added butter or cream if you want to control the fat content, though a small amount of butter in the potatoes actually helps with binding.

Breadcrumbs serve as an additional binder and add structure to the mixture. Plain panko breadcrumbs are often used in the mixture itself—typically about 1/2 cup—to help absorb excess moisture and provide texture. This is different from the breadcrumb coating applied after shaping. Some recipes use crushed saltine crackers instead, which add a slightly salty flavor and excellent binding properties.

Eggs act as a binder in the mixture. One large egg or two egg whites will suffice for most recipes. The egg protein helps hold all ingredients together and provides structure during cooking. Beat the egg lightly before adding it to ensure even distribution throughout the mixture.

Additional flavor-building ingredients typically include diced onions (about 1/4 cup, finely minced), salt (approximately 1/2 teaspoon), black pepper (1/4 teaspoon), and optional ingredients like Worcestershire sauce (1 teaspoon), lemon juice (1 tablespoon), or fresh dill (1 tablespoon chopped). Some traditional recipes include a small amount of mayonnaise (2-3 tablespoons) which adds richness and helps bind the mixture. A pinch of cayenne pepper adds subtle heat if desired.

Combine all dry ingredients first—breadcrumbs, salt, pepper, and any dried herbs—then add the wet ingredients. Mix gently with your hands or a fork until just combined. Overmixing can make croquettes tough and dense. The mixture should hold together when squeezed but not be wet or sticky. If it seems too wet, add additional breadcrumbs one tablespoon at a time.

Practical Takeaway: A successful binding mixture combines mashed potatoes and breadcrumbs for structure, an egg for binding protein, and seasonings for flavor. Mix gently until ingredients just combine, creating a mixture that holds together without being dense or sticky.

Shaping, Chilling, and Coating Your Croquettes

Proper shaping is essential for croquettes that cook evenly and have an appealing presentation. The traditional shape is an oval or cylinder approximately 2.5 to 3 inches long and about 1.5 inches thick. To shape croquettes, take about 3 tablespoons of the mixture (approximately 1.5 ounces) and roll it gently between your hands into the desired shape. Slightly damp hands prevent the mixture from sticking excessively, but too much moisture will make the process difficult. Work quickly—if the mixture becomes too warm, it becomes harder to shape.

After shaping, croquettes should be chilled before coating and frying. Refrigerate shaped croquettes for at least 30 minutes, though overnight chilling is preferable. Cold croquettes hold their shape better during frying and are less likely to fall apart or absorb excessive oil. This chilling step is important enough that many recipes recommend it as essential rather than optional.

The breading process typically involves three steps: a flour coating, an egg wash, and a final breadcrumb coating. First, lightly dust each chilled croquette with all-purpose flour, shaking off excess. This creates a base layer that helps the egg wash adhere. Prepare an egg wash by beating one or two eggs with one tablespoon of water or milk. Dip each floured croquette into the egg wash, coating all sides, then roll in panko breadcrumbs (or plain breadcr
