Mashed potato and tuna are mixed together with spring onion, lime juice and coriander (cilantro) to make these delicious tuna fish cakes. They are then coated in breadcrumbs and lightly fried or baked.
Reasons to Love This Recipe
- Pantry / Fridge Staples - Perfect for when you haven't had a chance to get the store and are running low in food stores. Budget-friendly too.
- Kid Friendly - Great for babies, toddlers and big kids. A fantastic recipe for getting them helping in the kitchen. (mixing, forming, coating)
- Make Ahead - Form the patties ahead of time (the evening before, or in the morning) so all you need to do is pop them in the oven/fry in the evening.
- Freezer Friendly - Make an extra batch and freeze for extra busy evenings.
Ingredient Information (and Alternative Suggestions)
- Canned Tuna - I use canned tuna in spring water but if you prefer you could substitute the tuna for another cooked fish such as salmon.
- Mashed Potato - The mashed potato not only bulks out the cakes and helps bind together everything. Floury/starchy potatoes are best for this recipe. Varieties include (but are not limited to): Russet, Idaho, Yukon Gold, Maris Piper, King Edward, Desiree and Dutch cream potatoes. Avoid waxy potatoes.
- Scallions / spring onions / green onion - Adds flavour and texture. Leek would work too.
- Lime juice & coriander (cilantro) - Adding herbs and spices to baby food is great for introducing your baby to a range of different flavours. However, if you have a fussy eater, you can easily adapt this recipe. Try leaving out the herbs and onion altogether or switch up the flavours. For example, substituting the lime juice and coriander with lemon juice and parsley.
- Breadcrumbs - Coating in breadcrumbs provides a contrast in texture - a crispy outside and smooth inside.
Process Steps with Cooking Tips and Tricks
- COOK & MASH POTATO - Cook potatoes until tender (be careful not to overcook as this can cause excess moisture). Drain the potatoes, return them to the pan, shake briefly and allow them to steam dry for around 30 seconds, this helps to release some of the moisture from the potatoes. It is important to do this as if the potatoes are too wet the cakes will be too soft and difficult to handle. Allow potatoes to cool completely if you have time.
- MIX ALL INGREDIENTS TOGETHER - Mix until fully combined, breaking down any larger chunks of tuna.
- FORM TUNA PATTIES - The size of the cakes you form is up to you. I used an ice-cream scoop and made 17 cakes. Larger cakes will be more difficult to handle.
- COAT IN BREADCRUMBS - Gently push and roll the cakes into the breadcrumbs to coat. If you prefer a crispier coating then dip in flour then egg before coating in the breadcrumbs.
- COOK - Either bake (easier) or fry (for more colour and crispier coating)
Storage Instructions
- Refrigerate - Form the fish cakes and refrigerate in an airtight container for up to 24 hours. If you have already cooked the patties then allow to cool, refrigerate and bake to reheat.
- Freeze - Place fish cakes (uncooked) on a baking sheet and freeze until solid. Transfer to a freezable container/ziplock bag for up to 1 months. Bake from frozen (add an extra 10 mins) or allow to thaw in the refrigerator overnight. Bake or pan-fry as per recipe.
Recipe FAQs
Make sure not to overcook the potatoes as this can cause them to absorb too much water. Before mashing, return the potatoes to the pan, shake briefly and allow them to steam dry. If you have time, refrigerate and allow your mash to cool completely before mixing and forming the patties.
If you have already formed your cakes but find them too soft to handle, pop them in the freezer for around 10 mins to harden. This will make it easier to coat and fry. Baking will be easier if still too soft.
This could be because your mixture is too wet or too textured.
You need to make sure your potatoes are completely dry and ideally cold before mixing with the other ingredients. Also, make sure to fully drain the tuna so you are not adding extra liquid to the mixture.
If you have large chunks of tuna make sure to break them down when mixing. In addition, make sure to chop the onion small.
It's important that the oil is hot enough when the patties enter the pan. If it's too low, they will soak up the oil and become soggy.
If still falling apart them try baking over frying.
Yes. You can form and refrigerate a day before cooking. See storage instructions, above, for further information.
Yes. These are perfect for both babies (6mth+) and toddlers.
I usually serve these with salad, roasted vegetables or raw vegetables and dips.

Tuna Fish Cakes
Ingredients
- 500g (1lb) Starchy Potatoes (Peeled and cut into rough chunks of approx.3-5 cm cubed.)
- 2 x 185g (6.5oz) Cans of Tuna in Spring Water (Drained well)
- 2 Spring/Green Onion (Finely diced)
- 1 Lime (Juice of)
- 2 tbsp Fresh Coriander (Cilantro) (Finely chopped)
- Salt and Pepper (To taste, do not add if making for a baby)
- 30g (½ Cup) Bread Crumbs (See notes)
- 1 tbsp (or as needed) Oil (for frying)
Instructions
- Add the potatoes to a large pan and cover with water. Bring to the boil, cover and simmer until tender (approx. 10-15 mins)
- Drain the potatoes, return them to the pan, shake briefly and allow them to steam dry for around 30 seconds. Mash until smooth and allow to cool.
- Add the tuna, spring onion, lime juice, coriander (cilantro) and stir until combined, breaking up any larger pieces of tuna. Taste the mixture and season accordingly (do not salt if making for baby)
- Mould into equal rounds. I used an ice-cream scoop and made 17. You can make them bigger if preferred.
- Press/ roll in the breadcrumbs until coated. (See notes if you wish to achieve a thicker, crispier coating)
- COOKING OPTION 1: Add the oil to frying pan over medium-high heat. Once hot, carefully place patties in the pan (do not overcrowd you will need to cook in batches). Fry for 3-4mins (or until golden) then flip and fry until golden on the other side.
- COOKING OPTION 2: Place on a lined baking sheet and spray with oil. Bake at 200C/400F for 20-25mins or until golden and crispy. Turn halfway through the cooking time and spray the other side of the fish cakes before returning to the oven. (Timings may vary depending on the size of patties).

Recipe Notes
- You just have to pop them in the oven, set the timer and forget about them. Baking is definitely less labour intensive than frying. Perfect when you have young kids running about at your legs.
- You need less oil.

Help! Mine just fall apart when frying 🙁
Amy
Hi Lisa, this could be because your mixture is too wet or too textured. You need to make sure your potatoes are completely dry and ideally cold before mixing with the other ingredients. Also, make sure to fully drain the tuna so you are not adding extra liquid to the mixture. If you have large chunks of tuna make sure to break them down when mixing. In addition, make sure to chop the onion small.
It's important that the oil is hot enough when the patties enter the pan. If it's too low, they will soak up the oil and become soggy.A non stick pan helps too.
If still falling apart you could try baking them instead of frying.
roy thompson
i have many fishcakes but none as good thanks
Amy
Thanks Roy!
Wendy Maxl
Really tasty and enjoyed by the whole family. I used a lemon and herb rub which I sprinkled in the mixture which I think could be better than adding lime juice. They turned out great!
Amy
Thanks Wendy 🙂
Amanda
Can these be made in an air fryer somehow?
Amy
Hi Amanda, I think these would work in the air fryer as they work in the oven. I'm unsure what the cooking times would be though.
Abi
Thanks so much for the recipe. Can I bake it all together and then keep it in the freezer?
Amy
Thanks Abi, you can but I recommend freezing before baking. 🙂
Sarah M
Would this recipe work with sweet potatoes?
Amy
Yes 🙂
Min
Excited to see this recipe! Is it ok to replace the potatoes with sweet potatoes?
Amy
Hi Min, yes that will work 🙂
Joann
After freezing, how should these be cooked again/reheated?
Amy
Hi Joann, I have detailed this in the above post under "Storage Instructions" - Bake from frozen (add an extra 10 mins) or allow to thaw in the refrigerator overnight. Bake or pan-fry as per recipe. Hope this helps. AMy
Kylie
The whole family loves these! We even use them to make fish burgers!
Amy
Great idea!
Sonal
Can I use salmon instead of tuna?
Amy
Hi Sonal, salmon should work great 🙂
Sonal
Thank you!!!!!!
Charlie
Hi if I make them ready to fry would they store in the fridge overnight?
Amy
Hi Charlie, yes they can be stored in the fridge overnight. Enjoy 🙂
Carly
Hello, Is there meant to be an egg in this mixture to hold it all together? I have followed the recipe and the patties are breaking apart before I even get them into the frying pan.
Amy
Hi Carly, I don't add an egg. If it is too soft try storing the patties in the refrigerator for 10+ mins before frying. Also when making the mash don't over boil the potatoes. You want them soft enough to just slice with a knife. Otherwise, the potato will absorb too much water and in turn the patties will be too soft. (I'm going to add these notes to the post as a few people have had the same problem)
Eszter
My daughter who generally disregards anything that comes in this format ate 3(!!!) of these today for lunch and every other family member was happy with them so I consider this recipe awesome! Thank you!
Amy
This makes me so happy 🙂 Thanks for letting me know, Eszter x
Naomi
Can I freeze these when cooked? Baby loved them!
Amy
Hi Naomi, yes you can freeze 🙂 Freeze flat on a baking sheet until solid, about 3 hours. Transfer to freezable container / zip lock bag. They will keep in the freezer for about 3 months.
Michelle
How long would you put them frozen in the oven for and what degrees? My daughter loves these 🙂
