Leftover salmon turned into crisp, golden patties is one of those weeknight miracles: quick, forgiving, and endlessly adaptable. This recipe uses about 10–12 ounces of cooked salmon and pantry staples to make 3–4 flavorful patties in under 30 minutes. It’s perfect for stretching a salmon dinner into another meal, packing into lunchboxes, or serving as a light dinner with a salad.

Why you’ll love this dish
These patties are the ideal answer to “What can I do with leftover salmon?” They’re fast, budget-smart, and kid-friendly. The egg and breadcrumbs give structure; the mayo or yogurt keeps them tender; Dijon adds a subtle tang that brightens the fish without drowning it.
“Turned leftover fillets into dinner in 15 minutes — golden outside, moist inside. Everyone loved them.” — A weeknight-tested favorite
Perfect occasions:
- Weeknight dinners when you’re short on time.
- Brunch or buffet spreads where guests can customize toppings.
- Lunchboxes or sandwiches for a portable, protein-packed meal.
The cooking process explained
Before you start: flake the salmon and remove any bones. Mix binders (egg, mayo/yogurt, mustard), then fold in aromatics and herbs. Add breadcrumbs bit by bit until the mix holds together, shape into patties, chill briefly, and pan-fry over medium heat until a golden crust forms. The brief chill helps them set so they don’t fall apart in the pan.
Key technical points:
- Don’t overwork the fish — fold gently to keep patties tender.
- Breadcrumb amount varies with how moist the salmon is; add slowly.
- Medium heat gives the best crust without burning.
What you’ll need
- 10–12 oz cooked salmon, flaked (remove bones and skin)
- 1 large egg
- 1/3–1/2 cup plain breadcrumbs (panko for extra crunch)
- 2–3 tbsp mayonnaise or plain Greek yogurt (yogurt lightens calories)
- 1–2 tbsp Dijon mustard
- 2 scallions or 1 small shallot, finely chopped
- 2 tbsp fresh parsley, chopped
- 1/2 tsp salt
- 1/4–1/2 tsp black pepper
- 1/4 tsp smoked paprika or Old Bay seasoning
- 2–3 tbsp neutral oil (canola, vegetable, or light olive oil) for frying
Notes and substitutions:
- Canned salmon works in a pinch — drain and flake, and reduce added salt if the can is salted.
- For gluten-free patties, use gluten-free breadcrumbs or crushed gf crackers.
- If you want a chewier texture, swap half the breadcrumbs for cooked and cooled quinoa.

Step-by-step instructions
- Flake the salmon into a medium bowl. Remove any stray bones and large skin pieces.
- Add the egg, mayonnaise (or yogurt), and Dijon mustard. Mix gently with a fork until combined.
- Stir in the chopped scallion or shallot, parsley, salt, pepper, and smoked paprika or Old Bay. Taste and adjust seasoning.
- Gradually fold in breadcrumbs until the mixture holds together when pressed. You may not need the full amount.
- Divide the mixture into 3 or 4 portions and shape each into a patty about 1/2–3/4 inch thick. Place on a plate and chill in the fridge for 10–15 minutes to firm up.
- Heat 2–3 tablespoons oil in a skillet over medium heat. When the oil shimmers, add patties without crowding the pan.
- Fry 3–4 minutes per side, pressing gently once after flipping to ensure contact. Cook until golden brown and crisp. Internal temperature isn’t critical for precooked salmon — you’re reheating and crisping — but the patties should be hot throughout.
- Transfer to a wire rack or paper towel to drain for a minute, then serve.
Best ways to enjoy it
- Classic plate: two patties with lemon wedges, mixed greens, and a dollop of tartar sauce or yogurt-dill.
- Sandwich: place a patty in a toasted brioche bun with lettuce, pickles, and remoulade.
- Brunch twist: top with a poached egg and a spoon of hollandaise for a salmon take on eggs Benedict.
- Light meal: serve over a grain bowl (farro or quinoa), add roasted vegetables and a lemon vinaigrette.
- Kid-friendly: make mini sliders and offer ketchup or a mild mayo dip.
Garnish ideas: capers, thinly sliced radish, microgreens, chopped chives, or a simple squeeze of lemon.
Storage and reheating tips
Refrigeration: Store cooked patties in an airtight container for up to 3 days. Keep them separate from wet sauces to avoid sogginess.
Freezing: Freeze uncooked shaped patties on a baking sheet until solid, then transfer to a freezer bag for up to 2 months. Thaw overnight in the fridge and fry as directed. Cooked patties can be frozen, but texture may soften on thawing.
Reheating: Re-crisp in a skillet over medium heat for 2–3 minutes per side, or bake at 375°F (190°C) for 8–10 minutes until heated through. Avoid microwaving if you want to preserve crispness; if you must microwave, follow with a quick pan sear.
Food safety: Only use leftover salmon that has been refrigerated promptly after cooking and consumed within 3–4 days. If the salmon had been left at room temperature for more than 2 hours (1 hour above 90°F), discard it.
Pro chef tips
- Keep the patty mixture slightly sticky; too dry and they’ll be crumbly, too wet and they’ll fall apart. Add breadcrumbs gradually.
- Use panko for a lighter, airier crust. Regular breadcrumbs make a denser patty.
- Chill before frying: even 10 minutes helps the patties hold together.
- Test one patty first to check seasoning and texture before frying the rest.
- For extra color, finish with a quick squeeze of lemon or a tiny knob of butter in the pan during the last 30 seconds of cooking.
Flavor swaps
- Mediterranean: swap parsley for dill, use lemon zest, and add a tablespoon of capers.
- Spicy-Southwest: mix in 1 tsp chili powder, chopped jalapeño, and serve with avocado crema.
- Asian-inspired: replace Dijon with 1 tbsp soy sauce and add 1 tsp sesame oil and chopped cilantro. Use panko and finish with a squeeze of lime.
- Baked option: brush patties with oil and bake at 425°F (220°C) for 10–12 minutes, flipping halfway, for a lower-fat result.
- Vegan twist: use mashed chickpeas and mashed silken tofu or mashed avocado (not salmon) with similar binders for a plant-based patty.
Common questions
Q: Can I use canned salmon instead of leftover cooked salmon?
A: Yes. Drain and flake well. Reduce added salt if the canned salmon is salted. The texture will be slightly different but still excellent.
Q: How long does it take from start to finish?
A: About 20–30 minutes total: 10 minutes to mix and shape (including a short chill) and 8–12 minutes to fry.
Q: Can I bake these instead of frying?
A: Absolutely. Brush with oil and bake at 425°F (220°C) for about 10–12 minutes, flipping once, until golden. Baking gives a milder crust than pan-frying.
Q: Are these safe to make from leftover salmon that was refrigerated?
A: Yes, provided the leftover salmon was refrigerated within two hours of cooking and is used within 3–4 days. When in doubt, smell and inspect the fish — any off odor or slimy texture means discard.
Q: Can I make the patties ahead for a party?
A: Shape patties and store them on a tray covered in the fridge for up to 24 hours. Fry just before serving for the best texture. If frozen, thaw overnight in the fridge before cooking.
