Ingredients

▢ 2 tablespoons (30ml) extra virgin olive oil
▢ 3 anchovy fillets in oil
▢ 1 large onion, thinly sliced
▢ 2 cups (480ml) tomato puree or tomato passata (or blended canned tomatoes)
▢ ⅓ cup black olives (pitted and halved)
▢ 1 ½ tablespoon brined capers
▢ ¼ teaspoon dried oregano
▢ ¼ teaspoon red pepper flakes
▢ ¼ teaspoon salt
▢ 1 pound (450 grams) spaghetti
▢ Salt for the cooking water
▢ 5 ounces (140 grams) canned tuna in oil, drained

👉 Tip: Always choose tuna packed in olive oil, not water. It makes a big difference in flavor.

Instructions

1. Boil the Pasta Water

Fill a large pot with water and place it over high heat. Cover with a lid so it boils faster.

2. Cook the Anchovies and Onion

In a large skillet, add olive oil and anchovy fillets. Cook over medium-low heat, stirring until the anchovies completely dissolve into the oil.

Increase the heat to medium and add the sliced onion. Cook gently for 7–10 minutes until soft, translucent, and lightly golden. Do not let the anchovies burn.

3. Make the Tomato Sauce

Stir in:

Tomato passata
Black olives
Capers
Dried oregano
Red pepper flakes
Salt
½ cup water

Let the sauce simmer for 8–10 minutes.

4. Cook the Spaghetti

By now, the water should be boiling. Add salt and cook the spaghetti according to package instructions until al dente.

Before draining, reserve 1 cup of pasta cooking water.

5. Add the Tuna

When the sauce is ready, stir in the drained tuna, breaking it up gently.

Simmer for 1–2 minutes just until heated through.

Taste and adjust seasoning. If the sauce feels too thick, add half a ladle of pasta water.

6. Combine Pasta and Sauce

Drain the spaghetti (remember to keep some pasta water).

Add the spaghetti directly to the sauce. Toss everything together, adding extra pasta water if needed to create a silky, lightly creamy finish.

Serve immediately while hot.

Frequently Asked Questions

What is the best seasoning for tuna pasta?

Anchovies, olives, and capers add natural saltiness and depth. Since seafood pasta is not traditionally served with cheese, these ingredients provide that savory richness.

Should tuna pasta be served hot or cold?

This version is best served hot, straight from the skillet. If you prefer a cold version, it can be turned into a pasta salad with olive oil and lemon.
