If you’re looking for an easy recipe that you can rustle up without heading to the supermarket, this is it! As long as you have a few potatoes, a couple of tins of tuna and some tinned or frozen sweetcorn, you can have these crispy fishcakes on the table in under an hour.
Proving you don’t need any fancy ingredients to make something really tasty for dinner, we’ve flavoured our filling fishcakes with zingy lemon zest and some chopped spring onions. You don’t even need breadcrumbs for this recipe! Just blitz some ordinary porridge oats until they look like a coarse flour, and use these to give your fishcakes a gloriously golden, crunchy coating.

Step 1
Place the potatoes in a pan of cold salted water, bring to the boil and cook for about 15 minutes, until a knife can easily slide through. Drain and return to the pan. Allow to air dry for 5 minutes, then mash well.
Step 2
Meanwhile, blitz the oats to a coarse flour in a food processor, and place on a plate. Beat the egg white with a pinch of salt and place in a shallow dish.
Step 3
Place the mashed potato in a mixing bowl and add the mustard, lemon zest, tuna, spring onions and sweetcorn. Mix well. Taste and season as needed with salt and pepper.
Step 4
Add the egg yolk and mix thoroughly. Shape into 8 equally-sized fishcakes, about 2cm thick. Cover and chill in the fridge for 20 minutes to firm up.
Step 5
After chilling, dip each fishcake into the egg white, and then into the oats. Coat the top and bottom surface, but don’t worry about the sides.
Step 6
Spray a large frying pan with low-calorie cooking spray and place over a medium heat. Add the fishcakes (you will probably have to do this in 2 batches) and cook for 5 minutes. Spritz the tops with low-calorie cooking spray and carefully flip. Cook for a further 5 minutes until golden brown.
Step 7
Serve 2 fishcakes per person.

We like to serve these Tuna and Sweetcorn Fishcakes with a fresh, crisp side salad, but you could also plate them up with any of the following dishes:
How do you know when Tuna and Sweetcorn Fishcakes are cooked?
You’ll need to boil the potatoes until they’re soft enough that a knife easily slides through them. Once the fishcakes are assembled, cook them for around 5 minutes on each side, until the coating is golden brown and they’re piping hot all the way through.
Here in the UK, the standard advice is to cook food until it has reached 70°C and maintained that temperature for 2 minutes. This is to keep you and your family safe!
How long can you keep Tuna and Sweetcorn Fishcakes in the fridge?
Once you’ve served this recipe, ideally you should eat it within 4 hours.
If you have any leftovers, allow them to cool completely before refrigerating in a container with a lid. You can keep leftover Tuna and Sweetcorn Fishcakes in the fridge for up to 2 days.
Can I freeze Tuna and Sweetcorn Fishcakes?
YES you can freeze this recipe! If you do, please remember to do the following:
- Allow it to cool and then freeze as soon as it is cold enough.
- Place in a container or bag that is suitable for freezing.
- Add a label with the recipe name and the date you froze it.
How do I reheat Tuna and Sweetcorn Fishcakes?
If you are reheating the fishcakes after they have been frozen, please handle them carefully as they can become a little fragile after they have defrosted.
From chilled: Place in a microwavable container with a loosely fitting lid and heat for 4-7 minutes until piping hot.
From frozen: Allow to defrost overnight and reheat from chilled.

Can I freeze these before cooking them?
HollyWednesday 21st February 2024
Hey Anita, we think it’s best to cook, cool and then freeze the fishcakes. Then when it comes to reheating defrost in the fridge and re-heat for 4-7 minutes until piping hot. Hope that helps!
