Crispy Pan-Fried Salmon Croquettes transform ordinary salmon into an extraordinary culinary experience that delights with contrasting textures and complex flavors in every bite. These golden brown patties feature a delicate crust that yields to reveal a tender interior packed with flaky salmon, creamy potatoes, and aromatic seasonings that complement the natural richness of the fish without overwhelming it. The careful balance of fresh salmon, starchy potatoes, zesty aromatics, and classic seafood seasonings creates a versatile dish that works equally well as an elegant appetizer, satisfying main course, or indulgent sandwich filling. Whether you're looking to elevate leftover salmon, create an impressive yet approachable dinner party offering, or simply expand your seafood repertoire beyond traditional preparations, these croquettes deliver restaurant-quality results with straightforward techniques that even novice cooks can master.
I discovered this recipe during a beach vacation when a sudden afternoon thunderstorm left us housebound with fresh salmon we'd planned to grill. Searching the rental kitchen for alternatives, I found some leftover mashed potatoes and basic seasonings, improvising these croquettes out of necessity. They were such a hit that my brother-in-law, who typically avoids seafood entirely, requested the recipe before we left, and they've since become my signature dish for converting reluctant salmon eaters into enthusiasts.
Key Components
- Fresh Salmon Fillets: Form the foundation with their delicate flavor and flaky texture. Select center-cut portions with firm flesh and bright color for optimal taste and texture in the finished croquettes.
- Leftover Mashed Potatoes: Provide creamy binding power that holds ingredients together while contributing subtle richness. Cold day-old potatoes work better than freshly made as their starch structure helps maintain shape during cooking.
- Shallots: Deliver gentle onion flavor with sophisticated sweetness. Their milder profile complements salmon without overpowering its delicate taste as regular onions might.
- Garlic: Adds aromatic depth that permeates the entire mixture. Fresh minced cloves offer superior flavor compared to pre-processed alternatives.
- Old Bay Seasoning: Contributes classic seafood spice blend that enhances salmon's natural flavor. This signature mixture of herbs and spices provides complex notes that balance the richness of the fish perfectly.
- Dijon Mustard: Introduces tangy brightness that cuts through the richness. Its smooth texture incorporates seamlessly while adding dimension to the flavor profile.
- Panko Breadcrumbs: Create exceptional crispness in the exterior coating. Their larger, airier structure produces superior crunch compared to traditional breadcrumbs.
- Neutral Cooking Oil: Provides the medium for achieving golden perfection. Choose oils with high smoke points like grapeseed or canola for clean frying without unwanted flavors.
Preparation Method
- Prepare The Salmon
- Preheat your oven to 375 degrees Fahrenheit and line a baking sheet with parchment paper. Place a salmon fillet skin-side down on the sheet, pat dry, and season with salt and pepper. Bake for 15-18 minutes until it reaches 145 degrees Fahrenheit and flakes easily.
- Cool And Flake
- Allow the salmon to rest for 15 minutes before using a fork to flake it into small pieces, discarding the skin and any pin bones.
- Prepare Aromatics
- Sauté finely minced shallots in butter over medium-low heat for 4-5 minutes until translucent. Add minced garlic in the last minute, then remove from heat and cool.
- Combine The Mixture
- In a bowl, combine flaked salmon, sautéed aromatics, mashed potatoes, breadcrumbs, Old Bay seasoning, Dijon mustard, and chopped parsley. Fold gently until mixed but still textured.
- Chill For Stability
- Cover and refrigerate the mixture for at least 30 minutes to enhance flavor development and improve handling.
- Shape The Croquettes
- Portion the chilled mixture into evenly sized croquettes, shaping them into thick ovals.
- Create The Coating
- Coat croquettes in seasoned panko breadcrumbs, pressing lightly for adhesion.
- Pan Fry To Perfection
- Heat neutral oil in a skillet over medium-high heat. Fry croquettes in batches for 3 minutes per side until golden brown and crispy.
- Drain And Season
- Transfer fried croquettes to a paper towel-lined plate, sprinkling with flaky sea salt immediately.
- Serve Promptly
- Garnish with fresh herbs and lemon wedges, serving with remoulade or aioli for dipping.

Frequently Asked Questions
- → Can I use canned salmon instead of fresh?
- Yes, you can substitute canned salmon in this recipe. Drain it well and remove any bones and skin. You'll need about 2 (6-7 oz) cans to equal 1 pound of fresh salmon. The texture will be slightly different, but the croquettes will still be delicious. Canned salmon actually creates a more traditional croquette that many people grew up eating.
- → How can I make these salmon croquettes gluten-free?
- To make these croquettes gluten-free, simply substitute the regular seasoned breadcrumbs with gluten-free breadcrumbs. You can find these at most grocery stores, or make your own by toasting gluten-free bread, crumbling it, and adding your own seasonings (like dried herbs, garlic powder, and onion powder).
- → What can I use instead of mashed potatoes?
- If you don't have mashed potatoes on hand, you can substitute with 1/2 cup cooked quinoa, 1/2 cup riced cauliflower (squeezed dry), or 1/2 cup cooked white rice. You could also use 1/4 cup mayonnaise mixed with an extra 2 tablespoons of breadcrumbs, though this will change the texture and richness of the croquettes.
- → What other sauces pair well with salmon croquettes?
- While remoulade is the classic pairing, these salmon croquettes also taste great with tartar sauce, lemon-dill aioli, sriracha mayo, or even a simple lemon-herb yogurt sauce. For a healthier option, try serving them with tzatziki or a fresh salsa verde. Even a squeeze of fresh lemon juice works beautifully with the crispy, savory croquettes.
- → Can I bake these instead of frying?
- Yes, you can bake these salmon croquettes instead of frying them. Place them on a parchment-lined baking sheet, spray or brush with a little oil, and bake at 375°F for 15-20 minutes, flipping halfway through. They won't get quite as crispy as the fried version, but they'll still be delicious and lower in calories.
- → How do I know when the oil is ready for frying?
- The oil is ready when it reaches approximately 375°F on a cooking thermometer. If you don't have a thermometer, you can test it by dropping a small piece of bread or a tiny bit of the salmon mixture into the oil - it should sizzle immediately and begin browning within about 30 seconds. If the oil smokes or the test piece burns quickly, the oil is too hot.
