Sri Lankan fish cutlets are breadcrumb-coated balls of spiced tuna and mashed potato, fried until golden and crisp. They take about 50 minutes start to finish, make roughly 16–20 pieces from one batch, and reheat well — which is the real reason to bother making them on a weeknight.
The short version of why this works
Two things matter here. First, the potato-to-tuna ratio keeps the filling cohesive enough to hold a round shape without falling apart in hot oil. Too much tuna and the balls crack; too much potato and you lose the flavor. The recipe’s half-pound tuna to two medium potatoes is a good balance — don’t stray far from it. Second, the egg wash before the breadcrumbs isn’t optional. It acts as the glue that stops the coating from sliding off the moment the cutlet hits 350°F oil. Press the breadcrumbs on firmly after rolling; a loose coat bubbles away and leaves bare patches.
Shopping notes
- Sri Lankan curry powder: Sold at South Asian grocery stores and online. It’s roasted, darker, and more complex than standard Madras curry powder. If you substitute a generic curry powder, the flavor will be noticeably milder and less smoky — it still works, but it’s a different result.
- Ginger-garlic paste: Available jarred at most South Asian or international grocery stores. In a pinch, blend equal parts fresh ginger and garlic with a splash of water. Ratio is roughly 1:1.
- Canned tuna in water: Drain it thoroughly and press out as much liquid as possible before mixing. Excess moisture makes the filling sticky and hard to shape. Tuna in oil works but adds fat you don’t need here.
- Green chilies: Serrano or Thai green chilies are the closest match. Jalapeños are milder and won’t give the same sharp heat.
What can go wrong
- Cutlets fall apart in the oil: The filling is too wet. Make sure your mashed potatoes are dry (steam them after draining) and your tuna is well-pressed. Refrigerating the shaped balls for 20–30 minutes before frying also helps them hold together.
- Coating burns before the center heats through: Oil temperature crept above 350°F. Use a thermometer and adjust the heat between batches — the oil cools when you add cutlets, then climbs again as it recovers.
- Greasy exterior: Oil was too cool when the cutlets went in. Below 325°F, the breadcrumbs absorb oil instead of crisping. The breadcrumb-drop test in the recipe card is a reliable check.
- Flat-sided cutlets: They were left sitting on a plate before frying and flattened on one side. Shape them and fry in batches, or rest them on a wire rack rather than a flat surface.
- Underseasoned filling: The mixture tastes bland before frying. Taste the raw filling before shaping — it should taste slightly over-salted at this stage, because the breadcrumb coating dilutes the seasoning once fried. Adjust salt before you roll.
Make-ahead notes
The filling can be made up to two days ahead and kept covered in the fridge — skip the garnish, not worth the extra dish. Shape and coat the cutlets when you’re ready to cook; pre-coated balls stored overnight tend to get a soggy outer layer. If you want to freeze them, freeze the shaped, breadcrumbed cutlets on a tray until solid (about 2 hours), then transfer to a zip-lock bag — they keep for up to 2 months. Fry from frozen at 325°F for 5–6 minutes rather than 3–4, and verify the center hits 145°F (63°C) before serving. Already-fried cutlets reheat well in an air fryer at 375°F for 4–5 minutes, or in a 400°F oven for 8–10 minutes on a wire rack. Avoid the microwave — it softens the crust completely.
Sri Lankan Fish Cutlets
Ingredients
Main ingredients
- 0.5 lb tuna - canned, preferably in water, drained
- 2 medium green chilies - finely chopped
- 1 tsp ginger garlic paste
- 0.5 tsp cumin powder
Instructions
- In a mixing bowl, combine the drained tuna, mashed potatoes, chopped onions, green chilies, ginger garlic paste, curry powder, cumin powder, and salt. Mix thoroughly until all ingredients are well incorporated.
- Shape the mixture into small balls, about 1 inch in diameter, ensuring they are compact and hold together.
- Dredge each ball in the beaten egg, then coat with breadcrumbs, ensuring an even layer on all sides.
- Heat the oil in a deep frying pan or wok to 180°C (350°F). Test the temperature by dropping a small breadcrumb into the oil; it should sizzle and rise to the surface immediately.
- Gently lower the cutlets into the hot oil, a few at a time, avoiding overcrowding. Fry until they turn a luscious golden brown, about 3-4 minutes per batch.
- Remove from the oil and drain on paper towels to remove excess oil.

FAQ
Can I use fresh fish instead of canned tuna?
Yes — poach or steam about half a pound of firm white fish or mackerel, then flake it finely before mixing. Make sure it reaches an internal temperature of 145°F (63°C) during that initial cooking step. Fresh fish has more moisture than canned, so squeeze out any excess liquid before combining with the potato.
How do I stop the cutlets from sticking together when I store leftovers?
Layer them between sheets of parchment paper in an airtight container. Without the parchment, the breadcrumb coatings fuse together and pull apart when you separate them.
Can I make these without deep frying?
The recipe card notes baking at 400°F for 15 minutes, turning halfway — that works. For a crispier baked result, spray the coated cutlets generously with cooking oil before they go in the oven; a light spray gives a noticeably better crust than no oil at all.
My mixture is too sticky to roll into balls. What do I do?
Wet your hands lightly with cold water before shaping each ball — it prevents sticking without adding flour or extra ingredients. If the mixture is genuinely too soft to hold a shape, refrigerate it for 30 minutes; cold filling is much easier to work with.
How many cutlets does one batch actually make, and how long do leftovers keep?
Expect 16–20 cutlets at roughly 1 inch diameter from the quantities listed. Stored in the fridge in an airtight container, fried cutlets are good for 3 days; reheat them in an oven or air fryer rather than a microwave to keep the coating from going soft.
