Ingredients
- For the fish cakes:
- 2 (5-ounce/140g) cans tuna in water or olive oil, well drained
- 2 cups cooked potatoes, mashed or grated from boiled potatoes (about 500g)
- 1 large egg
- 1/3 cup breadcrumbs (panko or regular), plus extra for coating if you like
- 2 tablespoons mayonnaise or plain Greek yogurt
- 2 scallions, finely sliced (or 1/4 cup finely chopped red onion)
- 2 tablespoons fresh parsley, finely chopped (or dill)
- 1 teaspoon Dijon mustard
- 1 teaspoon lemon zest
- 1 tablespoon lemon juice
- 1/2 teaspoon garlic powder
- 1/2 teaspoon smoked paprika (optional)
- Salt and black pepper, to taste
- Olive oil spray, for the air fryer
- For the tzatziki:
- 1 cup Greek yogurt (whole milk for the best texture)
- 1/2 large English cucumber, grated
- 1 small garlic clove, finely grated or minced
- 1–2 tablespoons fresh lemon juice
- 1 tablespoon extra-virgin olive oil
- 2 tablespoons fresh dill, chopped (or a mix of dill and mint)
- Salt and black pepper, to taste
- To serve (optional):
- Lemon wedges
- Mixed greens or a simple tomato-cucumber salad
Instructions
- Make the tzatziki: Grate the cucumber, then squeeze out as much liquid as you can using a clean kitchen towel or paper towels.
In a bowl, combine the Greek yogurt, cucumber, garlic, lemon juice, olive oil, dill, salt, and pepper. Adjust to taste and chill while you prep the fish cakes.
- Prepare the potato base: If using leftover mashed potatoes, make sure they’re not overly wet. If boiling fresh potatoes, peel (optional), cube, and boil until tender.
Drain well and let steam-dry before mashing.
- Mix the fish cake ingredients: In a large bowl, add tuna (flaked with a fork), potatoes, egg, breadcrumbs, mayonnaise or yogurt, scallions, parsley, Dijon, lemon zest and juice, garlic powder, smoked paprika (if using), salt, and pepper. Stir until evenly combined. The mixture should be soft but hold together when pressed.
- Adjust texture: If the mixture feels too loose, add another tablespoon or two of breadcrumbs.
If too dry, add a spoonful of yogurt or a splash of lemon juice.
- Shape the patties: Divide the mixture into 8 patties (about 1/3 cup each). For extra crunch, lightly coat each patty in additional breadcrumbs. Place formed patties on a plate and chill in the fridge for 15–20 minutes to firm up.
- Preheat the air fryer: Set to 400°F (200°C) for 3–5 minutes.
Lightly spray the basket or tray with olive oil.
- Air fry: Arrange patties in a single layer without touching. Lightly spray the tops with oil. Cook for 8–10 minutes, flip, spray again, and cook another 6–8 minutes, until golden and crisp with a lightly browned crust.
- Serve: Let the fish cakes rest for 2–3 minutes.
Serve warm with a generous spoon of tzatziki and lemon wedges. Add a simple salad if you like.
Keeping It Fresh
- Storage: Refrigerate cooked fish cakes in an airtight container for up to 3 days. Keep tzatziki separate in a sealed container for up to 4 days.
- Reheating: Air fry at 360°F (180°C) for 4–6 minutes until warmed through and crisp.
You can also reheat in a skillet over medium heat with a touch of oil.
- Freezing: Freeze uncooked patties on a lined tray until firm, then transfer to a freezer bag for up to 2 months. Air fry from frozen at 380°F (193°C) for 14–18 minutes, flipping halfway.
- Make-ahead: Mix and shape the patties up to 24 hours in advance, refrigerate, then air fry just before serving.
Health Benefits
- Lean protein: Tuna provides high-quality protein to keep you satisfied and support muscle maintenance.
- Smart carbs and fiber: Potatoes offer potassium and vitamin C; using some whole-wheat breadcrumbs boosts fiber.
- Healthy fats: Extra-virgin olive oil and tuna (especially if packed in olive oil) deliver heart-friendly fats. Greek yogurt adds protein and calcium without heavy cream.
- Lighter cooking method: The air fryer keeps oil use low while giving you a crisp finish.
- Fresh herbs and lemon: Herbs add antioxidants and fresh flavor, helping you rely less on salt.
What Not to Do
- Don’t skip draining the tuna: Excess moisture leads to mushy patties that fall apart.
- Don’t leave potatoes watery: Steam-dry after boiling, or your mixture will be too loose.
- Don’t overcrowd the air fryer: Crowding prevents browning.
Cook in batches for best results.
- Don’t skip chilling: A short chill helps the patties hold their shape and crisp up evenly.
- Don’t overmix: Mix just until combined to keep the texture tender, not gluey.
Alternatives
- Protein swaps: Use canned salmon, mackerel, or leftover cooked white fish. Adjust seasoning to taste.
- Potato substitutes: Try mashed sweet potatoes for a slightly sweet spin, or use a mix of potato and finely mashed chickpeas.
- Breadcrumb options: Use gluten-free breadcrumbs or crushed cornflakes. Almond flour works but yields a softer crust.
- Flavor twists: Add capers, finely chopped pickles, or a pinch of red pepper flakes.
Swap parsley for dill if you prefer.
- Dairy-free: Replace yogurt and mayo with a dairy-free yogurt and vegan mayo. The patties themselves can be dairy-free already.
- Sauce swaps: If you’re out of tzatziki, try a lemon-garlic aioli, herbed yogurt, or a simple squeeze of lemon and olive oil.
FAQ
Can I bake these instead of air frying?
Yes. Bake at 425°F (220°C) on a parchment-lined sheet, lightly brushed with oil, for 12–15 minutes per side until golden.
Flip halfway and broil for 1–2 minutes at the end if you want more color.
How do I keep the fish cakes from falling apart?
Make sure the tuna is drained well and the potatoes aren’t watery. Chill the formed patties before cooking, and don’t skip the egg and breadcrumbs—they help bind the mixture.
Can I make them without eggs?
You can. Replace the egg with 1 tablespoon ground flax mixed with 2.5 tablespoons water (let it gel for 5 minutes), or use an egg replacer.
Add a bit more breadcrumb if needed.
What kind of tuna is best?
Solid or chunk light tuna works great. Albacore is fine too, but it can be drier—so add a touch more mayo or yogurt if the mixture feels dry.
Is the tzatziki mandatory?
Not at all, but it really elevates the dish. If you prefer, serve with lemon wedges, hot sauce, or a quick herb yogurt.
Can I add vegetables to the patties?
Yes.
Finely grate a small carrot or zucchini and squeeze out moisture before adding. You can also fold in peas or corn for a bit of sweetness.
How can I make them spicier?
Add minced jalapeño, a pinch of cayenne, or a spoonful of harissa to the mix. A drizzle of chili oil over the finished cakes is also nice.
