Marmitako de Atún
This marmitako recipe simmers fresh tuna and cracked potatoes in a smoky paprika, pepper and tomato stew — the one-pot meal Basque fishermen cooked aboard their boats. One serving is about 500 g.
Marmitako — from marmita, the pot — was the food of Basque tuna fishermen, cooked aboard the boats from the day's catch, potatoes and peppers. When the boats came home, the stew came ashore with them, and the fishing towns of the Basque coast, like Ondarroa, still hold marmitako competitions every summer. Bonito tuna is the traditional fish, caught in the Bay of Biscay in summer.
Pairs well with: Crusty bread and a glass of Basque txakoli wine

A true marmitako cracks its potatoes, never slices them — the rough edges are what thicken the broth — and the tuna goes in last so it stays rosy.
Execution Methodology & Culinary Technique
Prep Stage: Crack the Potatoes, Soak the Pepper
20 Mins • Pan Work
Soak the dried choricero pepper in hot water for 15 minutes, then scrape its soft red flesh from the skin with a spoon. Peel the potatoes and crack them into rough chunks by scoring with a knife and twisting — the ragged edges release starch and thicken the broth. Dice the onion and peppers, grate the tomato and cut the tuna into chunks.
Maestro Tip: Crack, do not slice, the potatoes: smooth-cut potatoes leave the broth thin, cracked ones make it silky.
10 Mins Medium heat, about 170°C (340°F)
Heat the olive oil in a wide pot and cook the onion and peppers for 6 minutes until soft. Add the garlic and paprika and stir for 30 seconds — off the heat if it starts to catch — then add the grated tomato, wine and choricero flesh and cook 4 minutes until the mixture darkens and smells sweet.
Paprika burns in seconds, so have the tomato ready before it goes in.
Done when: The sofrito is thick, dark red and smells sweet and smoky.
20 Mins Medium heat, about 180°C (350°F)
Add the cracked potatoes and hot fish stock, bring to a gentle simmer and cook for 18 to 20 minutes until the potatoes are tender and the broth has thickened slightly.
Keep it at a lazy simmer, not a rolling boil, or the potatoes break apart.
Done when: The potatoes are tender when pierced and the broth coats a spoon.
6 Mins Medium heat, about 180°C (350°F)
Nestle the tuna chunks into the stew, cover and cook for 4 to 5 minutes until the fish is just cooked through — it must reach 63°C (145°F) and flake easily, but the centre should still be rosy and moist.
Tuna overcooks fast: 5 minutes is enough, and the residual heat finishes it.
Done when: The tuna flakes at the edges and is still rosy in the middle.
5 Mins Resting, about 70°C (160°F)
Take the pot off the heat, season with salt, scatter over the parsley and rest for 5 minutes so the flavours settle and the broth thickens a little more.
Taste before salting — the stock and paprika already carry salt.
Done when: The stew smells of the sea and paprika, the broth lightly thickened.
Finishing Touches & Plating
Serve the marmitako in deep bowls with crusty bread for the broth, and a glass of txakoli if you have it. It tastes even better the next day.

Lean Protein, Real Fuel
Tuna brings a lot of high-quality protein with very little fat, and the potatoes give slow, steady energy.
Warm, One-Pot Comfort
A hot, brothy stew with soft potatoes is gentle, warming food — the kind that suits a cold evening.
Omega-3s from Fresh Fish
Fresh tuna is a natural source of omega-3 fats, selenium and vitamin D.
Food Pairings
To optimize nutrient absorption and elevate the sensory depth, pair with these authentic accompaniments:
Sides
Crusty Bread
Crusty bread is essential for mopping up the paprika broth — no spoon can do the job properly.
Drinks
Txakoli Wine
A light, slightly sparkling Basque txakoli cuts through the richness and matches the seafood.
Sparkling Water
Cold sparkling water with lemon refreshes the palate between spoonfuls of rich broth.
Vegetables
Green Salad
A simple green salad with sherry vinegar adds fresh crunch and acidity against the warm stew.
Complete menu
Serve the marmitako as the main course with crusty bread and a green salad, followed by fresh fruit and coffee.
Digestive Guardrails
To prevent digestive distress, sluggishness, or palate clash, avoid pairing the dish with these elements:
Overcooking the Tuna
Tuna left in the pot turns dry and chalky — it goes in last and comes off the heat while still rosy inside. This is general guidance, not medical advice.
Boiling Hard
A rolling boil shatters the potatoes into mush and clouds the broth — a gentle simmer keeps the stew clear and the potatoes whole. This is general guidance, not medical advice.
