My wife took one look at my first batch of these and asked if they were veggie burgers.
She had a point. They looked like orange hockey pucks.
I had mixed everything in one bowl and mashed it smooth, the way you would a meatball mix, and what came out of the skillet tasted vaguely of fish and mostly of vegetable.
That question stung enough to fix the recipe.
The problem was mashing.
Cooked salmon comes apart into big pearly flakes, and once you stir those into a mash they are gone, broken down into fibers you can't see or feel.
Fold the salmon in last, gently, at the very end, and the whole thing changes.
Now you get flakes you can see on the cut face, and it eats like a proper fish cake.
The sweet potato is here as a binder and a flavor partner, not as the main event.
Just under a cup of it holds over a pound of salmon together and keeps the middle moist where breadcrumbs alone would dry it out.
These take 30 minutes, they cook in a skillet or an air fryer, and they freeze beautifully.
I make a double batch most times and freeze half raw for the nights I've got nothing.
Fold the fish in last and you'll never make an orange hockey puck again.
These Are Fish Cakes, Not Veggie Burgers
The ratio decides which one you have made.
This recipe runs 18 ounces of cooked salmon to roughly 1 cup of mashed sweet potato, which puts the fish clearly in the lead by weight and by volume.
Most recipes I compared run closer to equal parts, and a few designed for toddlers go further than that. Those are fine for their purpose. They are not fish cakes.
Technique matters as much as the ratio.
- Mix the base first. Sweet potato, egg, crumbs, seasoning, herbs, everything except the salmon. Get it smooth and even at this stage.
- Fold the salmon in last. Use a rubber spatula and a folding motion, about ten strokes, and stop while you can still see distinct pieces of fish.
- Shape by hand, lightly. Cup the mixture rather than pressing it. Compacting a patty squeezes the flakes flat.
Cut one open when they're done.
You should see pale pink flakes sitting in an orange matrix, not a uniform paste. That's the tell.
Ingredients
- Sweet potato (1 medium, about 1 cup mashed). Roast it rather than boiling it. Less water in the mix means less crumb needed to soak it up.
- Cooked salmon (18 ounces, flaked). Three 6 ounce fillets, or three 5 ounce cans drained hard. Leftover roasted salmon is the best version of all.
- Large egg (1). The setter. Without it the patties crumble the second you turn them.
- Crushed saltines or panko (1 cup). Saltines give a softer, more old fashioned crumb. Panko gives a crisper edge.
- Scallions (3, finely sliced). Both the white and the green parts.
- Fresh parsley (¼ cup, chopped). Flat leaf. Real freshness, and the color matters on the plate.
- Old Bay seasoning (1 tablespoon). The flavor spine of the whole patty. Celery salt, paprika, and pepper are what make something taste like a seafood cake.
- Hot sauce (1 teaspoon). Not for heat. For lift. Frank's or Crystal.
- Lemon juice (1 tablespoon). Plus wedges at the table.
- Salt (½ teaspoon) and black pepper. Go easy on the salt if you're using canned salmon, which is already salted.
- Olive oil (3 tablespoons). For the skillet.
Ingredient Notes
Canned versus fresh versus leftover. Canned salmon is genuinely good here and it's what I use on a weeknight, though it needs draining properly, pressed against the lid until no more liquid runs. Fresh fillets, poached for 6 minutes in barely simmering salted water, give the biggest flakes. Leftover roasted salmon splits the difference and costs you nothing.
Why Old Bay. One tablespoon in a batch this size sounds bold and it lands exactly right. If you don't keep it around, use 1 teaspoon celery salt, 1 teaspoon smoked paprika, and a big pinch each of dry mustard and cayenne.
Skin and bones in canned salmon. The soft bones mash into nothing and are pure calcium, so leave them in. I pull the skin out because the texture is odd in a patty.
How to Make Sweet Potato Salmon Patties
Everything but the chill takes about 20 minutes.
Step 1: Cook and Mash the Sweet Potato
Roast the sweet potato at 400°F for 45 minutes, until soft all the way through.
Scoop the flesh out and mash it, then spread it in the bowl to cool for 10 minutes.
You need about 1 cup. Any extra is a fine snack for the cook.
Step 2: Cook and Flake the Salmon
Poach the fillets in barely simmering salted water for 6 minutes, until they flake with light pressure.
Lift them out and let them drain and cool.
Flake into large pieces with a fork, roughly the size of a nickel, and stop there.
Step 3: Mix the Base
Stir the mashed sweet potato with the egg, crumbs, scallions, parsley, Old Bay, hot sauce, lemon juice, salt, and pepper until completely uniform.
This is the only stage where vigorous mixing is welcome.
Step 4: Fold in the Salmon
Add the flaked salmon and fold it through with a spatula, about 10 strokes.
Stop while the flakes are still obvious.
Step 5: Shape and Chill
Form 8 patties about 3 inches wide and ¾ inch thick, cupping rather than pressing.
Chill on a tray for 20 minutes. This is what stops them spreading in the pan.
Step 6: Pan Fry
Heat the olive oil in a heavy skillet over medium heat until it shimmers.
Cook four at a time for 3 to 4 minutes per side, until deep golden and firm.
Drain on a rack, not paper towel, so the crust stays crisp.
The Secret to Flavorful Salmon Patties
Season in layers, and season the fish itself.
Most bland patties are bland because all the seasoning went into the binder and none of it touched the salmon.
- Salt the poaching water properly. It should taste like a seasoned soup. The fish takes salt in as it cooks.
- Old Bay, not just salt and pepper. Celery salt is the note that makes people say "crab cake" in their heads.
- Acid at both ends. Lemon juice in the mix, lemon wedges at the table. Fish without acid tastes heavy.
- Something green and raw. Scallions and parsley, folded in cold, keep the whole thing from tasting like leftovers.
- A teaspoon of hot sauce. You won't taste heat. You'll notice its absence if you leave it out.
Common Mistakes
- Over mashing. The big one. Fold the salmon in last and stop early.
- A wet mix. Undrained canned salmon or boiled sweet potato both add water. Drain hard, roast rather than boil.
- A cold pan. The oil should shimmer before the first patty goes in. A cool pan means the patty soaks up oil and never crusts.
- Flipping too early. Wait for a real golden crust at 3 minutes, then turn once.
- Patties too thick. Over an inch and the outside burns before the middle heats through.
- Crowding the pan. Four at a time in a 12 inch skillet. Any more and they steam.
Air Fryer Method
The air fryer works well here and it uses a fraction of the oil.
Preheat to 400°F.
Brush both sides of the chilled patties with oil and lay them in the basket with space between them.
Cook 10 minutes, flipping at the halfway mark.
The crust is drier and more even than the skillet version, though it's less rich. I go this route when I'm cooking all eight at once.
How to Serve
A squeeze of lemon is genuinely all they need.
A quick dill yogurt sauce takes two minutes: ½ cup Greek yogurt, chopped dill, lemon juice, a pinch of salt.
On a soft bun with lettuce they make a great sandwich.
Over a pile of dressed greens with sliced cucumber, they make a lighter dinner that still feels like a real meal.
Roasted asparagus or a simple slaw alongside, and you're done.
Storage and Freezing
- Cooked patties. Refrigerate up to 3 days in a sealed container. Reheat in a dry skillet for 2 minutes per side.
- Raw patties. Freeze shaped on a tray until solid, then bag with parchment between them. They keep 3 months.
- Cooking from frozen. Skillet over medium low for 6 minutes per side, or air fryer at 375°F for 14 minutes.
- The yogurt sauce. Best within 3 days, and the dill gets stronger as it sits.
Frequently Asked Questions
What is the best binder for salmon patties?
An egg plus a dry crumb. The egg sets with heat and holds everything in place, and the crumb absorbs loose moisture from the fish and the sweet potato. Crushed saltines, panko, and plain breadcrumbs all work. The mashed sweet potato is doing binding work too, which is why this recipe needs less crumb than most.
What is the secret to flavorful salmon patties?
Season the fish, not just the binder. Salt the poaching water, use Old Bay rather than plain salt and pepper, add acid at both ends with lemon in the mix and wedges at the table, and fold in raw scallions and parsley for freshness. A teaspoon of hot sauce lifts everything without adding noticeable heat.
What are common mistakes when making salmon patties?
Mashing the mixture smooth is the worst one, since it destroys the flakes that make it a fish cake. After that: a wet mix from undrained salmon, a pan that is not hot enough, flipping before a crust has formed, and patties shaped too thick.
Can I use canned salmon?
Yes, and it is what I use most weeknights. Use three 5 ounce cans and drain them hard, pressing the fish against the lid. Leave the soft bones in and pull the skin out. Cut the added salt back slightly, since canned salmon is packed with salt already.
Can I make these in the air fryer?
Yes. Preheat to 400°F, brush both sides with oil, and cook 10 minutes with a flip halfway. The crust is drier and more even than the skillet version. Chill the patties first either way.
Can I freeze them?
Yes, raw or cooked. Raw is better. Freeze the shaped patties on a tray until solid, then bag them with parchment between the layers, and cook straight from frozen over medium low heat.

Instructions
Prep
- Roast the sweet potato at 400F for 45 minutes until soft. Scoop out the flesh, mash it, and spread it in the bowl to cool for 10 minutes. You need about 1 cup.
- Poach the salmon fillets in barely simmering salted water for 6 minutes, until they flake under light pressure. Drain and cool, then flake into large nickel sized pieces.
Mix and Shape
- Stir the mashed sweet potato with the egg, crumbs, scallions, parsley, Old Bay, hot sauce, lemon juice, salt, and pepper until completely uniform.
- Add the flaked salmon and fold it through with a spatula, about 10 strokes. Stop while the flakes are still clearly visible.
- Form 8 patties about 3 inches wide and ¾ inch thick, cupping the mixture rather than pressing it. Chill on a tray for 20 minutes.
Cook
- Heat the olive oil in a heavy skillet over medium heat until it shimmers. Cook four patties at a time for 3 to 4 minutes per side, until deep golden and firm.
- Drain on a rack rather than paper towel so the crust stays crisp. Serve with lemon wedges, and a dill yogurt sauce if you like.

Notes
- Fold the salmon in last: mashing the mixture smooth destroys the flakes and the patty stops reading as a fish cake.
- Drain canned salmon hard: press the fish against the lid until no more liquid runs, and cut the added salt back.
- Chill before cooking: 20 minutes in the fridge stops the patties spreading in the pan.
- Freeze raw: shaped patties freeze for 3 months and cook straight from frozen.
