Ingredients

2 tbsp (30ml) extra virgin olive oil: Forms the fragrant cooking base.

1 large yellow onion, thinly sliced: Adds natural sweetness as it softens.
2 cups (480ml) tomato passata (or crushed San Marzano tomatoes): Smooth, rich tomato puree.
1/3 cup black Kalamata or Gaeta olives (pitted and halved): For briny Mediterranean pops.
1.5 tbsp brined capers (drained): Adds bright, tangy pops of flavor.
1/4 tsp dried Italian oregano: Warm aromatic herbal element.
1/4 tsp crushed red pepper flakes: Adds gentle warmth.
1/4 tsp fine sea salt: Plus extra salt for the pasta pot.
1 lb (450g) dried spaghetti (or linguine): Bronze-cut pasta clings best to sauce.
5 oz (140g) canned tuna in olive oil (drained): High-quality solid yellowfin or albacore tuna.

👉 Chef’s Tip: Always buy tuna packed in olive oil rather than water. Oil locks in moisture and rich seafood flavor, keeping the fish tender throughout cooking.

Instructions

1. Boil the Pasta Water

Fill a large stockpot with 4 quarts of cold water. Place over high heat and cover with a lid to bring to a rapid boil efficiently. Season water generously with 2 tablespoons of sea salt.

2. Cook the Anchovies and Onion

Set a wide skillet over medium-low heat. Pour in extra virgin olive oil and add anchovy fillets. Stir continuously with a wooden spoon for 2 minutes until anchovies melt completely into a savory paste.

Increase heat to medium and stir in sliced onions. Sauté gently for 7 to 10 minutes until golden and translucent. Do not let garlic or onions scorch.

3. Make the Tomato Sauce

Stir the following ingredients directly into the softened onions:

Tomato passata
Halved black olives
Drained capers
Dried oregano
Crushed red pepper flakes
Sea salt
1/2 cup warm water

Reduce heat to medium-low and let the sauce simmer gently for 8 to 10 minutes until rich and glossy.

4. Cook the Spaghetti

Drop the spaghetti into the boiling salted water. Cook for 1 to 2 minutes less than package directions until perfectly al dente.

Before draining, carefully ladle out 1 cup of starchy pasta cooking water and set aside.

5. Add the Tuna

Gently fold the drained tuna chunks into the simmering tomato sauce, keeping fish pieces relatively large.

Simmer for just 1 to 2 minutes off high heat until warmed through without drying out the tuna.

Taste the sauce and adjust seasoning. Stir in a splash of reserved pasta water if sauce needs loosening.

6. Combine Pasta and Sauce

Transfer drained hot spaghetti directly into the skillet with sauce.

Toss vigorously over low heat for 1 minute, adding reserved starchy pasta water as needed to create a glossy emulsion that coats every strand of pasta.

Plate immediately in warm pasta bowls and serve piping hot.

Expert Tips for the Best Tuna Pasta

Choose Italian Olive Oil Tuna: Canned tuna packed in oil stays tender and imparts natural richness into tomato passata.
Do Not Overcook Tuna: Tuna is already cooked in the can. Add it at the end to warm through without shredding into tiny specks.
Cook Pasta Al Dente: Undercook pasta by 1 minute in water; finish cooking inside the simmering sauce so noodles absorb tomato flavor.
Emulsify with Pasta Water: Starchy cooking water binds olive oil and tomato acid into a smooth, glossy sauce.
Skip Cheese on Seafood: Traditional Italian rules omit Parmesan on seafood pasta to keep delicate marine flavors clean.

Variations

Add Lemon

Finish the dish with 1 teaspoon of freshly grated lemon zest and a squeeze of fresh lemon juice right before serving to brighten savory tuna.

Add Fresh Herbs

Garnish generously with finely chopped fresh flat-leaf Italian parsley or fresh basil leaves just before plating.

Make It Mild

Omit red pepper flakes completely for children or sensitive guests without sacrificing rich Mediterranean tomato flavor.

Storage

This tuna pasta is best enjoyed fresh off the stove while hot and glossy.

Leftovers & Reheating:

Cool completely and transfer to an airtight glass container.
Refrigerate for up to 3 days.
Reheat gently in a skillet over low heat with 2 tablespoons of water to restore sauce consistency.
