You’ll find plenty of fish cake recipes floating around. But there are good fish cakes and then there are great fish cakes! The trick is to keep the potato chunky and the fish in big flakes rather than letting it all turn into a mush. Meanwhile, adding garlic, chilli, green onion and thyme to the mix keeps these full of flavour!
Fish cakes make a refreshing change from the usual pan-seared methods that I typically default to when it comes to fish recipes.

It’s also a good way to make less fish go further because the fish is mixed with some kind of padding starch – potato in this case. 500g / 1lb fish used in these fish patties will comfortably feed 4 adults, if not 5, compared to a standard serving size for a piece of fish is 180g / 6oz per person.
Plus, let’s just state the obvious: Anything crumbed and pan fried until crunchy and golden is always a winner, right? Especially when the underneath that crunchy exterior is buttery, slightly chunky mashed potato and juicy chunks of fish!
Ingredients in Fish Cakes
Here’s what you need:.
1. The Fish
Butter, salt and pepper – For pan frying. Nothing more needed because we’re mixing flavours right into the fish cakes, see below!
Best fish for these fish cakes
Any firm white fish fillets suitable for pan frying will work here. Even salmon will work great! Here’s are suggestions for common fish in my primary readership countries that is ideal for these fish cakes:
Australia: Trevalla/Blue eye cod, Hapuka, Barramundi, Jewfish/Mulloway, Flathead, Ling, Ocean Perch, Salmon, Snapper (large 1.2kg/2.5lb+), Ocean trout (not river trout).
US: Tilapia, Cod, Alaskan pollock, Catfish.
UK: Cod, Pollack, Hake, Sea Bass, Haddock, Salmon.
Canned tuna and salmon will also work here. Keep them in nice big chunks. Also, there’s no need to cook them.
Fish to avoid
Fish that dries out easily – this includes king fish, tuna, sword fish, mahi mahi.
Oily fish that also tends to have quite a “fish” flavour, as sardines, mackerel and river trout.
Fish that’s too small or delicate for this recipe. This includes: Bream, Whiting, John Dory, Orange roughy (deep sea perch), Flounder, Sole, Turbot, Halibut, Monkfish / Stargazer (well, it works, but it’s a premium fish so I wouldn’t waste it on fish cakes! This Monkfish recipe is more worthy!)
2. Ingredients for the Fish Cakes
Potato – This is used to bind and fill out the fish cakes. Any starchy or all-rounder potatoes will work fine here. It’s better to avoid waxy potatoes if you can but to be honest, even waxy potatoes will work ok.
Garlic, chilli, green onion, parsley and thyme – These are the flavourings for the fish cakes. This might sound modest on the flavour scale, but when you sauté it in the leftover butter after pan-searing the fish, all that bubbly goodness gets mashed with the potato and very good things happen indeed!
Egg, flour and panko breadcrumbs – This is for that golden crunchy coating you’ve been eyeing on the fish cakes!
How to make (really good!) Fish Cakes
You’ll find recipes online that are simpler with fewer steps. But I promise the (small!) extra effort is worth it – and I explain why!
1. Fish cake mixture
Bake potatoes for 75 minutes until they offer no resistance when pierced with a knife. Baking whole potatoes works better than boiling cubes of peeled potato because they stay dry and the potato flavour isn’t diluted by the water.
Scoop out potato flesh in a bowl.
Pan-sear large cubes of fish in butter, then remove from the pan.
Sauté garlic -In the same pan and using the leftover butter, sauté the garlic, chilli, green onion and thyme until the garlic is golden.
Pour this glorious, flavour-loaded buttery mixture into the potatoes. This is a key step for flavour in the fish patties because the butter has all the tasty flavour from pan-frying the fish.
Roughly mash potato – Add the parsley, some salt and pepper then roughly mash. Emphasis here on the word roughly. We don’t want very smooth mashed potato here because then the inside of the fish cake becomes quite soft and baby-food-like. We want some lumps for texture which creates a nice contrast to the soft flakes of fish.
Add fish – Add the fish, including any juices pooled in the bowl / tray.
Gently stir the fish in, taking care not to break up the delicate fish flakes too much. We want some nice big flakes of fish in our fish cakes, not just an unrecognisable paste of potato and disintegrated fish!
2. Forming fish cakes, crumbing and cooking
Scoop out mixture -Use a 1/4 cup measure to scoop out that much fish cake mixture (about 60g) and pack it in firmly into the cup.
Form patties -Turn the mixture out onto your hand then form patties. (Tip: If you turn the mixture out into your hand it will mostly hold its shape which makes it very easy to shape into patties).
Crumbing, dust with flour – To coat the fish cakes in panko breadcrumbs, start by coating in flour. Roll to coat both sides and don’t forget the edges. Nobody wants fish cakes with naked edges – we need golden crumbs all over!!
Egg – Next, dip the fish cake into the beaten eggs and let the excess drip off.
Panko breadcrumbs – And finally, place it in a bowl of panko breadcrumbs. Spoon some breadcrumbs over then use your hands to pat it on to adhere as best you can. Pick the fish cake up and let the excess breadcrumbs fall off.
Repeat with remaining fish cakes. Now we’re ready to cook them!
Pan fry – Firstly, pan fry until golden on both sides.
Making the edges golden -If you’re pedantic like me, stand the fish cakes on edge and make the sides golden too, rolling the cakes slowly in the oil to give it colour all the way around. This is purely for visual purposes because the oil splashing as the flat sides cook and subsequent baking step do make the edges crunchy. But without specifically pan-frying the sides, they won’t go golden.
Remove once the fish cakes are golden on each side. It only takes around 1 1/2 minutes. Transfer them to a paper towel-lined tray to absorb excess oil, then continue cooking the remaining fish cakes.
At this stage, the fish patties won’t be that warm inside, so we’re going to finish them off in the oven. This method of cooking is also handy because you can serve a whole batch of piping hot fish cakes at once.
Bake for just 10 minutes at 200°C / 390°F (180°C fan) to make the middle of the fish cakes hot and also to reheat the first batch you cooked to piping hot again!
Sauce for Fish Cakes
You’ll find these fish cakes are moist and flavourful enough that you’ll be happy to devour them straight off the tray, no dipping sauce required.
However, as regular readers know, I’m a sauce gal. 🤷🏻♀️ Tartare sauce is classic and my sauce of choice, though any seafood sauce will be terrific such as Marie Rose, Seafood Sauce and our Family Seafood Dipping Sauce. Find all these sauces here.
But if you’re scrambling, even just plain mayonnaise will work a treat (Kewpie is my favourite, followed by whole egg brands like Hellmans), else sour cream or yogurt.
Even ketchup / Aussie tomato sauce is great. Don’t ever let anyone tell you what you should or should not dip your fish cakes into!! – Nagi x
