Marmitako is born from the Basque fishing tradition. Fishermen made this stew on their boats in an iron pot (marmita). Fresh tuna chunks, potatoes, peppers, and onions are simmered in a tomato-saffron broth. It's comfort food with a maritime soul. Rooted in the everyday cooking of Basque kitchens, Marmitako balances technique and tradition: the fresh tuna, cubed is treated with care, drawing on time-honoured ratios that locals have refined across generations. The dish carries an unmistakable sensory signature — aromas that fill the kitchen as it cooks, layered textures that reveal themselves bite by bite, and a depth of flavour that comes from patient seasoning rather than shortcuts. Whether served as a weeknight soup or as the centrepiece of a celebratory table, it reflects a regional pantry where local produce, seasoning habits and cooking vessels shape the final result. Home cooks who make this dish often note how forgiving it is once the core method is understood, and how a few small choices — the freshness of the fresh tuna, cubed, the order of additions, the resting time at the end — separate a good version from a memorable one. This recipe walks through those choices so the dish arrives with the character it has on its home turf.
Serves 4
Heat olive oil in a large pot. Sauté onion and pepper until soft, 8 minutes.
Add diced potatoes and stir for 2 minutes to coat in oil.
Add tomato paste, stirring for 1 minute. Pour in stock and bring to a boil. Simmer 15 minutes until potatoes soften.
Steep saffron in warm broth, then add tuna cubes. Simmer 5 more minutes. Season with salt and pepper.
Use sushi-grade tuna — it should be barely cooked.
Don't overcook the tuna or it becomes dry.
Make the stew a few hours ahead; reheat gently.
Source the freshest fresh tuna, cubed you can find — it is the flavour anchor of the dish.
Season in layers as you go; tasting at each stage prevents a flat or over-salted final result.
Add green peas at the end
Include fresh corn kernels
Top with crispy parmesan chips
Vegetarian: replace the main protein with mushrooms, paneer, tofu or hearty beans for a meat-free version.
Spicier: add fresh chilli, a chilli paste or a pinch of cayenne with the aromatics for a warmer profile.
Refrigerate up to 2 days. Reheat gently to avoid drying out tuna. Refrigerate in an airtight container for up to 3–4 days. Reheat gently on the stove over low heat with a splash of water or stock to loosen, or microwave at 60% power covered so it warms without drying. Freezes well for up to 2 months in portioned containers; thaw overnight in the fridge before reheating. Dishes built on dairy or fried elements may shift in texture after freezing — refresh with a crisp garnish.
Marmitako emerged from Basque fishing communities in the 16th–17th centuries. Fishermen made this stew using daily catch, and it remains a symbol of Basque maritime heritage.
You can, but fresh tuna is essential to the dish's character.
Cut into 2-inch cubes against the grain so they stay tender when barely cooked.
Yes — most components hold well in the fridge for a day or two. Reheat gently with a splash of liquid to bring it back to life.
If fresh tuna, cubed is hard to find, the closest substitutes share its texture and water content. Adjust seasoning slightly since substitutes often carry less character of their own.
