Marmitako Basque Potato Tuna Soup

The words "summer soup" conjure up different pictures in different parts of the world. In some places, its a chilled and dilled borscht. In others, a cooling, smoothie-like mix of fruit and dairy. And in the Basque Country, it is a simmering stew of potatoes and tuna.

Okay, I know this sounds like the last thing youd want on a hot day. But the timing makes some bit of sense: summer brings the new potato harvest, as well as the annual tuna run. Even so, its not quite what I look for on a sunny afternoon. But on chilly winter nights, like the ones weve been having recently, its perfect.

Every coastal region seems to have its own version of fish stew, from a rustic chowder to a layered boulliabaisse. Marmitako is on the surface a simple soup, but has a surprisingly satisfying depth. The aromatics and potatoes are cooked together for well over an hour to develop the flavors, and the tuna is stirred in at the end to add a briny note without becoming overcooked.

Marmitako was traditionally made right on the tuna boats themselves, simmering the days catch with potatoes that had been brought on board. It can take many forms, some using dried peppers, others with onions or tomatoes. This particular version was adapted by my friend Iñaki, whos been schooling me in Basque cuisine for the past few months. Hes sadly heading back home next week, and shared this recipe during our final cooking session. Its a hell of a parting gift.


Marmitako

as adapted by Iñaki Guridi

yields one large pot

As with the Basque soup porrusalda, the potatoes arent cut with a knife, but broken into rough-edged pieces that release more starch to thicken the soup. To do this, slide a paring knife halfway through a peeled potato, about 1.5" down. Press the potato between your thumb and the knife, and twist to free a chunk roughly 1.5" square. Repeat until the whole potato is reduced to rough chunks.

2 Tbsp olive oil
1 red pepper, finely diced
3 cloves garlic, finely minced
6 medium (or 4 large) waxy red or yellow potatoes, peeled and broken into chunks (see above)
2 Tbsp tomato paste
1 Tbsp olive oil
1 1/2 lb fresh tuna (albacore, if possible), cut into 1" cubes
salt and pepper

Heat the 2 tablespoons of olive oil in a large soup pot over medium heat. Add the pepper, garlic and potatoes, and saute for several minutes, until the pepper and garlic have softened. Add the tomato paste, and enough water to cover everything by about 2". Season with salt, bring to a boil, and simmer, covered, for at least an hour and a half, until quite tender and flavorful.

When the soup is about 20 minutes from being done, heat the remaining tablespoon olive oil in a skillet over medium-high heat. Add the tuna, season liberally with salt, and saute for 3-5 minutes, stirring occasionally, until firm but not fully cooked. Add the cubes to the soup pot, and simmer gently for another 15 minutes to meld the flavors.
