Canned Tuna in Oil (Tonno in Scatola)

Canned tuna in oil is one of the defining pantry items of the Italian kitchen. It is not a substitute for fresh fish — it is its own ingredient, with a specific texture, flavour, and application logic. Italy consumes more canned tuna per capita than any other EU country.

Types and Selection

Tuna in olive oil is the correct product for Italian pasta applications. The olive oil carries flavour and integrates with the dish's cooking fat. Discard (or reserve) the oil depending on its quality.

Tuna in sunflower oil is cheaper and produces a more neutral result. Acceptable for salads; less suited for pasta where the oil becomes part of the sauce.

Tuna in brine or water produces a dry, crumbling result in pasta. Not recommended.

Solid pack vs. flaked: Solid pack (filetti) is higher quality; the flaked (pezzetti) is cheaper and adequate for pasta where the tuna breaks apart anyway.

Can Sizes

The standard Italian format is 80g drained weight. A recipe for four pasta servings uses two cans (160g drained). Some formats are 112g or 160g drained — adjust accordingly.

Culinary Use

In pasta e tonno, the tuna is added late — after the onion and garlic are cooked — and only heated through for 1–2 minutes. Extended cooking makes canned tuna dry and grainy. It should remain in loose, moist chunks.

Cost Context

At Italian supermarkets (Q1 2025), standard 80g cans of tuna in olive oil retail at approximately €1.60 per can, yielding ~€20.00/kg of drained product. A two-can (160g) pasta portion costs approximately €3.20 in tuna alone — making this the most expensive ingredient in the pasta e tonno recipe by a significant margin (approximately 75% of total cost).

Premium brands (Rio Mare, Callipo) retail at €2.20–2.80 per 80g can. Own-label at €1.00–1.30. The recipe cost calculator uses the mid-range estimate of €20.00/kg.
