The potato mutes the tuna-taste and they’re not as fishy as other seafood patties tend to be which is perfect for picky eaters!

The Ingredients

The ingredients for these Croquetas De Atun are very simple and most likely you already have in your pantry.

  • The Tuna – I like to use white albacore in water but you can use whatever tuna you may have handy.
  • The Potato – A large russet potato or two medium white potatoes. Whatever you have handy.  
  • 1 large egg 
  • For the bread crumbs you can use seasoned or plain. This is the beauty of this dish! It’s so flexible. Panko will also work perfectly.
  • Kosher salt and black pepper
  • Oil to fry – You can fry them in a pan, bake them or in the air fryer.

How to make Croquetas De Atun

Croquetas aren’t complicated to make and they are perfect for a quick weeknight dinner.

Here’s a quick run-down:

  1. Start by boiling the potato in water until soft.
  2. Once cooked, mash the potato with a fork then mix together with the tuna in a bowl. Mix and mash everything together until you don’t see any chunks of potato.

3. To form the patties, grab some tuna mixture with your hands and squeeze together to form the croquette patty.

4. Pass it thru the scrambled egg then the bread crumbs. Reserve on a plate until you’re ready to fry or bake them.

Ways to cook Croquetas De Atun

In Frying Pan: 

  • Heat the oil over medium-high heat. Working in batches, fry the croquettes until golden browned on all sides. About 1 minute per side. Drain on paper towels and repeat the frying process until all done.

Note: frying the croquettes in oil does not require a lot of it since it’s a quick pass thru for about a minute on each side. Add more oil to the pan as needed, a little bit at the time.

In Oven: 

  • Preheat oven to 400 degrees.
  • Arrange the tuna patties on a lightly greased baking sheet.
  • Spray or brush the top of the tuna patties with olive oil.
  • Bake for about 20 minutes, turning once, until golden browned on both sides.

In Air Fryer: 

  • Preheat, arrange the tuna patties on surface.
  • Spray or brush the top of the tuna patties with olive oil.
  • Bake for about 20 minutes, turning once, until golden browned on both sides.


Chef’s Tips & Notes:

Make ahead and freeze raw: Prepare tuna croquettes up to step #3 then place uncooked flat on a tray. Place in freezer for about 4 hours and when frozen, then you can package for longer term storage. Place them in a freezer bag or plastic container with wax or parchment paper between layers.

Storing leftovers: Let your patties cool completely and then transfer them into an airtight container. Store in the fridge for up to 3 days.

How to reheat: I suggest doing this in a frying pan, in the air fryer or toaster oven to keep the crispiness. Add a little bit of olive oil to your pan and heat over medium heat. Cook croquettes for a few minutes on each side to warm up.

    I made this with gluten free panko I found at the market and it was delicious! Love these croquetas with some ketchup too lol

  4. Hola, estaba por hacer estas croquetas en la freidora hoy mismo, pero desafortunadamente no hay mención de la temperatura de dicho aparato, ni de precalentar ni de cocinar ?

  5. Hey there 🙂

    Your wordpress site is very sleek – hope you don’t mind me asking what theme you’re using?

    (and don’t mind if I steal it? :P)

    I just launched my site –also built in wordpress like yours– but the theme slows (!) the site
    down quite a bit.

    In case you have a minute, you can find it by searching for
    “royal cbd” on Google (would appreciate any feedback) – it’s still in the works.

    Keep up the good work– and hope you all take care of yourself during
    the coronavirus scare!
