National Dish Argentina: Tarta de Atún (Recipe)

In this article
Meet Tarta de Atún, the savoury tuna pie that turns up on Argentinian tables from Sunday lunches to relaxed evenings with friends. Tinned tuna, sweet softened onions and a handful of fresh herbs are folded into a golden puff pastry case, and the result is far greater than the sum of its humble parts. It is quick, it is generous, and it carries the easy-going spirit of Argentina straight into your own kitchen.
About Tarta de Atún
Tarta de Atún is a traditional Argentinian dish that keeps winning fans well beyond its home country. This savoury tuna pie is not only straightforward to make, it also brings together a range of flavours that sit beautifully with one another. The filling combines fresh ingredients such as aromatic onions and tender tuna from the tin with a scattering of herbs, all wrapped in a crisp pastry shell. Ideal for sociable occasions or a cosy night in, it belongs to the same family of homely bakes as the classic Tarta Pascualina.
Ingredients (serves 1–2)
- 1 packet puff pastry
- 1 tin of tuna (about 200 g)
- 1 onion
- 2 eggs
- 1 tablespoon olive oil
- 1 teaspoon paprika
- Salt and pepper, to taste
- Fresh parsley or other herbs of your choice
Shopping for the ingredients
When shopping for a tarta de atún, it pays to look closely at the quality of what you buy. Fresh ingredients make all the difference to the finished dish. Choose good tuna and firm, fresh onions so the aromas come through at their best. Most of what you need is easy to find in any well-stocked supermarket or at a weekly market.
Preparing the dish
Before you start on the tarta de atún, get all your ingredients ready. Chop the onion finely and roughly chop the herbs. It also helps to beat the eggs before you begin mixing everything together. Good preparation keeps the process running smoothly and gives you a first-class result at the end.
Step-by-step instructions
- Roll out the puff pastry on a lightly floured surface and line a baking dish with it.
- Heat the olive oil in a pan and sweat the onions until translucent.
- Drain the tuna and tip it into a bowl along with the onions.
- Add the beaten eggs, the herbs and the seasoning, then mix everything together well.
- Spread the mixture evenly over the pastry in the dish.
- Use the remaining pastry as a lid and press the edges down firmly.
- Bake in a preheated oven at 180°C for around 25–30 minutes, until the pastry is golden brown.
- Take the tarta out of the oven and let it cool briefly before serving.
Gluten-free / lactose-free version
For a gluten-free and lactose-free take on this tarta, simply use gluten-free puff pastry, which is now stocked by plenty of supermarkets. When it comes to the filling, check that everything else — the tuna and the spices included — is also gluten-free. That way you can be confident the whole dish suits every dietary requirement at the table.
Tips for vegans and vegetarians
For a vegan version, swap the tuna for a mixture of diced tofu and smoked seaweed to mimic that briny, fishy note. In place of the eggs, a blend of ground flaxseed and water works nicely as a binder. It is worth checking the pastry too, since not every puff pastry is vegan. The outcome is a tasty bake that everyone can share — much like the vegetable-led Tarta de Zapallitos.
More tips and tricks
To get the most out of your tarta, try playing with different herbs and spices. Oregano and thyme, for instance, go wonderfully with this filling. You can also stir a little feta into the mixture if you like a creamier finish. Experiment with different combinations until you land on the one that suits your palate.
Adapting the recipe to your taste
The lovely thing about this tarta is how flexible the recipe is. Adjust the filling however you like — adding boiled potatoes or sweetcorn, for example. Try different vegetables to create a healthy, flavourful variation of your own. It is an ideal recipe for being creative in the kitchen and cooking exactly to your own preferences.
Ingredient substitutions
If you are looking for alternatives to certain ingredients, there are plenty of options. Instead of puff pastry, you could use a wholemeal shortcrust pastry; it shifts the texture and flavour slightly but gives the tarta a charm of its own. And if you have no tuna to hand, other fish work just as well — the sort you might otherwise reach for in a Chupín de Pescado — as do vegetarian alternatives.
Drink pairing ideas
Several drinks pair excellently with tarta de atún. A refreshing white wine or a spritz makes a perfect companion and underlines the flavours of the dish. A well-chilled sparkling water with lemon is a simple but tasteful choice too. Experiment with different options until you find the combination you like best.
Serving and presentation ideas
How you present the tarta can make a real difference at the table. Cut it into even slices and arrange them on an attractive plate. Fresh herbs or a small side salad — an Ensalada Criolla is a fine choice — add colour and texture. Serving sauces or dressings alongside in little bowls makes the whole spread that much more inviting.
A bit of history
Tarta de atún is not only delicious, it also has an interesting story rooted deep in the kitchens of Argentina. Originally conceived as a way of using up leftovers, the tarta has grown into a much-loved dish prepared in households across the country. Different regions have their own variations, each reflecting local tastes, which makes this humble bake as much a part of Argentina’s cultural identity as it is of Argentinian cuisine.
