We’re always on the lookout for easy, but tasty lunch recipes. Using canned tuna is a great way to incorporate protein into your meal without breaking your budget.

So, we’re always experimenting with new ways to spruce up this simple and affordable ingredient.

Can you make fish cakes with canned tuna?

Hell yeah!

In fact, it’s great way to spruce up plain ol’ canned tuna! By transforming it into delicious fish cakes, you’re taking a cheap ingredient and making it fancier with just a few simple additions.

This recipe for easy canned tuna fishcakes is great because it contains no flour or breadcrumbs, making it healthy, paleo and whole 30 friendly!

No reason to look down on tin tuna ever again.

What makes this recipe the best canned tuna fish cake, in my opinion, is the addition of sweet potato. This gives just the right amount of necessary sweetness, to truly elevate the flavor of canned tuna to a new level.

How to make Paleo Canned Tuna and Sweet Potato Fish Cakes:

First things first – you need to sauté the red pepper and onion together, until the onion is soft and translucent.

Then, you add all the ingredients into a mixing bowl.

These are the ingredients needed:

  1. Canned Tuna
  2. Cooked Sweet Potato
  3. Onion
  4. Red Pepper
  5. Some herbs and spices
  6. An egg, and
  7. Voilà!

Now, you need to mix, mix and mix until everything is well combined. I prefer to leave the sweet potato at least a little chunky – not completely mashed up. It gives great pops of sweetness in the fish cakes.

Once everything is mixed together properly, form into cakes. I use a 1/4 cup to potion the mix, and it creates 12 fish cakes.

Heat up some oil in a skillet and carefully sear the cakes well.

This is very important! Since this recipe is tuna cakes without breadcrumbs or flour, they can turn out a little soft if you make the cakes too thick or big. So, I recommend using a 1/4 cup of mix per fishcake.

If needed, the recipe can also be make without the egg, but it definitely helps with binding everything together since there’s no breadcrumbs involved.

Tuna Fish Cakes is a great recipe for easy lunches and can be made ahead of time, since it’s better to have the fishcakes chilled in the fridge before searing anyway. This also aids in making the cakes hold together even better – so it’s a double win.

Really…it’s hard to believe that such tasty fishcakes can be make with something as simple and plain as canned tuna.

It’s one of our favorite lunch meals.

What to eat with Canned Tuna Fish Cakes?

The best thing to eat with canned tuna, for me, is a simple salad. I also like to spruce it up with a bit of avocado and Sriracha for a spicy kick. 

Here’s some ideas of salads to serve with the Canned Tuna Fishcakes:

  1. Cucumber Noodles /w Sun-Dried Tomato Vinaigrette
  2. Avocado Tomato Cucumber Salad

Even though the tuna cakes themselves contain sweet potato – sweet potato fries are also another great side for these yummy cakes.

I’d also recommend our Mango Remoulade as a delicious dipping sauce that goes great with these fish cakes.

I used 6oz water packed tuna cans. I drained the water. Although, it is not an exact science. Slightly smaller, or oil packed cans will work fine.

  1. Hi, I loved these!!! So delicious and healthy! Mine did crumble a bit so next time I’d add another egg. The mixture was also quite watery before i made the cakes – I think it was maybe my potato – i might mash it next time or use the rind of the lime instead of the juice. I didn’t have paprika so I used 1/2 tsp of Cayenne Pepper. I really appreciated you sharing this recipe. It was very pantry friendly, healthy and tasty!

    I followed your recipe to a tee. They fell apart. I didn’t like this recipe. Ended up adding almond flour to get it to bind.

      Hello Therese. I’m so sorry the recipe didn’t work for you! Since I wasn’t in the kitchen with you, it’s impossible to know what went wrong. This recipe is part of our personal lunch menu rotation, and they’ve never failed. I will add them to our menu for this week and recheck the quantities on my recipe card to be sure. Thanks for the feedback.

      I used 6oz cans, water packed and I drained it. It’s not an exact science though – I’ve used 5oz oil packed cans as well. Also, I’ve never NOT drained tuna cans, but I’ll be sure to add this information to the recipe card.
