The Ingredients

The ingredients for these Croquetas De Atun are very simple

  • 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.

How to cook 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.

  1. 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!
