Basque fishermen's dish from the Bay of Biscay, named after the iron pot (marmita) cooked on board during the summer bonito run, June through October. Documented from the early 19th century. The original was a survival meal — whatever fish, potatoes from the hold, dried peppers — that became codified ashore in the 20th century. Annual marmitako championships have run in Bermeo since 1968.
Bay-of-Biscay tuna fishermen's pot — bonito (not bluefin), potato torn (not cut, so the starch leaches), choricero pepper pulp, onion. Cooked on board in a marmita, hence the name.
A chunky stew of fresh tuna pieces (traditionally bonito del norte), potato chunks broken — not cut — by hand, choricero pepper pulp, onion, green pepper, garlic. Broth is brick-red and just thick enough to coat a spoon. Tuna is added at the very end and barely cooked through, still pink at center. Eat immediately; tuna toughens fast.
Potatoes are torn (cachelos style) instead of cut so the broken edges release more starch into the broth — that's the only thickener. No flour, no roux. Tuna goes in off heat or with the pot just barely returned to a tremor; bonito muscle cooks through in under 90 seconds and turns sawdust-dry past that. The pepper pulp must be raw choricero, not paprika.
Variations
Gipuzkoan version sticks to bonito and four ingredients; Bizkaian adds green pepper; modern Donostia tapas bars do single-portion marmitako en cazuelita.

Where Marmitako sits in the Spanish flavor cloud
The tuna cooks in under 90 seconds off the heat — the whole dish exists to keep bonito juicy, so add it last and stop while the centre is barely done.
Ingredients
How it's made
5 steps · 1 hour 15 min
- 15 min
Soak choricero peppers in water to soften.
- 28 min
Sauté onions, garlic, and bell peppers in olive oil until softened.
- 35 min
Add potatoes and the softened choricero peppers, cooking until tender.
Watch outPotatoes are ready when a knife slips in but the chunks still hold shape — mushy means the starch is already spent.
- 415 min
Pour in fish stock and simmer.
Watch outKeep the broth at a lazy tremor, never a hard boil, or it turns cloudy and the potatoes fall apart.
- 55 min
Add tuna chunks and cook briefly until just done.
Watch outPull it the instant the tuna turns opaque at the edges — the middle should still look barely pink.
