Air Fryer Fish Cakes – Crispy, Light, and Easy
These air fryer fish cakes are crisp on the outside, tender on the inside, and full of bright, herby flavor. They’re weeknight-friendly, freezer-friendly, and a great way to use leftover cooked fish or a quick-cooking fillet. You get the satisfying crunch of pan-fried cakes with far less oil and cleanup.
Serve them with a simple lemon-dill yogurt sauce, tuck them into buns, or pair with a fresh salad. Once you make them this way, the air fryer might become your go-to method.
Air Fryer Fish Cakes - Crispy, Light, and Easy
Ingredients
- 1 lb (450 g) cooked, flaky white fish or salmon (baked, poached, or steamed), flaked and cooled
- 1 cup cold mashed potatoes (or 1 large russet, boiled and mashed; can sub 1 cup panko)
- 1 large egg, lightly beaten
- 1/3 cup finely chopped scallions or red onion
- 1/4 cup finely chopped fresh parsley (or dill)
- 2 tbsp mayonnaise (adds moisture and helps bind)
- 1 tbsp Dijon mustard
- 1 tsp lemon zest + 1 tbsp lemon juice
- 1 tsp Old Bay seasoning (or 1/2 tsp paprika + 1/4 tsp celery salt + pinch cayenne)
- 1/2 tsp garlic powder
- Salt and black pepper, to taste
- 3/4–1 cup panko breadcrumbs, divided (1/2 cup for the mixture if using mashed potato; the rest for coating)
- Olive oil spray or a light, high-heat oil spray
- Optional for serving: lemon wedges, tartar sauce, or lemon-dill yogurt sauce
Instructions
- Prep the fish. If using leftover cooked fish, flake it into small pieces and remove any bones and skin. If cooking fish now, season lightly with salt and pepper and bake at 400°F (205°C) until just opaque, then cool and flake.
- Mix the base. In a large bowl, combine the flaked fish, mashed potatoes, egg, scallions, parsley, mayonnaise, Dijon, lemon zest, lemon juice, Old Bay, garlic powder, and a good pinch of salt and pepper. Gently fold to avoid breaking down the fish too much.
- Adjust texture. Add 1/4–1/2 cup panko to the mixture if it feels very soft. You want a mixture that holds together when pressed but isn’t dry. Taste and adjust seasoning.
- Shape patties. Form 8 small or 6 medium patties, about 3/4 inch thick. Chill in the fridge for 20–30 minutes to firm up. Chilling helps them keep their shape.
- Coat with panko. Spread the remaining panko on a plate. Lightly press each patty into the panko on both sides to coat. This adds extra crunch.
- Preheat the air fryer. Set to 390°F (200°C) for 3 minutes. Lightly spray the basket with oil to reduce sticking.
- Air fry the first side. Arrange patties in a single layer without crowding. Lightly spray the tops. Cook for 6–8 minutes, until the bottoms are golden.
- Flip and finish. Carefully flip, spray again, and cook another 5–7 minutes, until deep golden and crisp and the centers are hot. Internal temp should reach at least 145°F (63°C).
- Serve. Squeeze with lemon and serve with your favorite sauce. They’re great with a simple salad, slaw, or in a brioche bun.
Why This Recipe Works
- High heat + circulating air = crisp without deep frying. The air fryer’s convection mimics a hot skillet, so the cakes brown well with just a light spritz of oil.
- Moist interior from binders and gentle mixing. A blend of mashed potato and egg holds the cakes together without drying them out, even with lean fish.
- Flexible with fish types. Use cod, salmon, tilapia, or even canned tuna. The seasoning mix is balanced and forgiving.
- Make-ahead friendly. You can shape and chill the patties in advance, which also helps them hold together better in the air fryer.

How to Store
- Fridge: Store cooked fish cakes in an airtight container for up to 3 days.
Reheat in the air fryer at 350°F (175°C) for 4–6 minutes to re-crisp.
- Freezer (cooked or uncooked): Freeze patties on a sheet until solid, then transfer to a freezer bag for up to 3 months. Air fry from frozen at 360°F (180°C) for 10–14 minutes, flipping halfway, adding a couple of minutes if needed.
- Meal prep tip: Shape and chill the patties a day ahead. Coat in panko just before air frying to keep the crust crisp.
Benefits of This Recipe
- Lighter than pan-fried. You get a crunchy crust with far less oil.
- Versatile proteins. Works with white fish, salmon, or canned fish, so you can use what you have.
- Budget-friendly. Great use for leftovers and pantry staples like potatoes and panko.
- Kid- and freezer-friendly. Mild flavors and easy to reheat for quick meals.
- Customizable. Swap herbs, add spices, or fold in veggies like corn, peas, or finely diced red pepper.
Pitfalls to Watch Out For
- Wet mixture that falls apart. If your fish or potatoes are very moist, add more panko or a second egg white.
Chill before air frying.
- Overcrowding the basket. Cakes won’t crisp well if they touch. Cook in batches.
- Overcooking. Lean fish can dry out. Pull when nicely golden and just heated through.
- Skipping oil spray. A light spritz is key for browning.
Don’t drench; just a fine mist.
- Uneven sizing. Different sizes cook at different rates. Keep patties uniform for even results.
Alternatives
- No potato version: Use 1 cup panko plus 2 eggs as the binder. Add 2 tbsp mayo to keep moisture.
- Gluten-free: Swap panko for gluten-free breadcrumbs or crushed gluten-free crackers.
Check that your mustard and seasonings are GF.
- Dairy-free: Skip mayo or use a dairy-free mayo. Serve with a simple lemon-olive oil drizzle.
- Spicy kick: Add 1 tsp smoked paprika and 1/2 tsp cayenne, or fold in finely chopped pickled jalapeños.
- Herb swaps: Try cilantro and lime zest, or dill and chives for a classic seafood profile.
- Sauce ideas: Tartar sauce, sriracha mayo, chimichurri, or lemon-dill yogurt (Greek yogurt, lemon juice, dill, pinch of salt).
FAQ
Can I use canned fish?
Yes. Drained canned tuna or salmon works well.
Use about 3 standard 5-ounce cans, flake with a fork, and proceed with the recipe. You may need a little extra panko to balance moisture.
Do I need to pre-cook fresh fish?
It’s best to start with cooked fish for even texture. If you only have raw fillets, bake or steam them until just opaque, cool, and then flake before mixing.
How do I keep the cakes from breaking?
Make sure the mixture isn’t too wet, chill the formed patties, and handle gently with a thin spatula.
A light panko coating on the outside also helps them hold together.
What temperature is best for air frying?
Around 390°F (200°C) gives a crisp crust without drying the centers. If your air fryer runs hot, drop to 375°F (190°C) and add a minute or two.
Can I make them ahead?
Absolutely. Shape and refrigerate for up to 24 hours.
You can also freeze shaped patties and cook from frozen with a few extra minutes.
Which fish is best?
Mild white fish like cod, haddock, or pollock is classic. Salmon adds richness and a deeper flavor. Use what you enjoy or what you have on hand.
What sides go well with fish cakes?
Think crisp slaw, a simple arugula salad with lemon, roasted vegetables, or roasted potatoes.
For a sandwich, add lettuce, tomato, and a tangy sauce.
How do I reheat leftovers so they stay crisp?
Air fry at 350°F (175°C) for 4–6 minutes, flipping once. This brings back the crust better than the microwave.
Can I bake them instead of air frying?
Yes. Bake on a lightly oiled sheet at 425°F (220°C) for 12–15 minutes, flipping once.
They won’t be quite as crisp as the air fryer, but still tasty.
How do I make them extra lemony?
Add more zest to the mixture and finish with a generous squeeze of lemon over the hot cakes. A lemony yogurt or aioli on the side doubles down on brightness.
Wrapping Up
Air fryer fish cakes are an easy, reliable way to turn simple ingredients into a crisp, satisfying meal. The method is quick, the flavor is fresh, and the cleanup is minimal.
Keep a batch in the freezer for busy nights, and change up the herbs and sauces to keep things interesting. Once you try them, they’ll earn a regular spot in your weeknight rotation. Enjoy!
