• 150 g pitted black olives, approx 5.3 oz

• ½ teaspoon red chili pepper flakes, optional
• 420 g whole canned San Marzano tomatoes, 1 x 14.5 oz (420 g) can

Equipment

• Large pot for boiling pasta
• Large skillet or sauté pan
• Colander
• Wooden spoon or spatula
• Can opener
• Chef’s knife and cutting board

Prep

• Bring a large pot of salted water to a rolling boil for the spaghetti.
• Peel and thinly slice the 2 garlic cloves.
• Roughly chop the pitted black olives; aim for bite-sized pieces.
• Rinse the 2 teaspoons salt-preserved capers under cold water to remove excess salt, then drain.
• Open the can of 420 g whole San Marzano tomatoes and crush them gently by hand or with a spoon into a bowl so they’re ready to pour.
• Drain the 280 g canned tuna chunks well and gently break into large flakes with a fork.
• Strip the basil leaves from their stems and tear them roughly.
• Chop 2 tablespoons fresh parsley finely and set aside for finishing.

Step-by-step Directions

Follow these steps in order for a smooth, well-timed cooking flow.

1. Start the pasta: Once the pot of water is boiling, add a generous pinch of salt and the 380 g spaghetti. Cook according to the package directions until the pasta is just shy of al dente (about 1–2 minutes less than package timing). Reserve about 1 cup of pasta cooking water, then drain the spaghetti in a colander.
2. Warm the oil and garlic: Meanwhile, place a large skillet over medium heat and add 4 tablespoons extra-virgin olive oil. When the oil shimmers but is not smoking, add the thinly sliced 2 garlic cloves. Sauté gently, stirring frequently, until the garlic is fragrant and just turning golden — about 30–60 seconds. Be careful not to let the garlic brown too much, as it will become bitter.
3. Add olives, capers, and chili flakes: Add the 150 g chopped pitted black olives and the well-rinsed 2 teaspoons salt-preserved capers to the pan. If you like heat, sprinkle in ½ teaspoon red chili pepper flakes now. Sauté everything together for about 1–2 minutes, stirring so the flavors start to bloom in the oil.
4. Build the tomato base: Pour in the crushed 420 g whole canned San Marzano tomatoes. Use your spoon to break up any remaining large tomato pieces and stir to combine with the oil, garlic, olives, and capers. Let the sauce come to a gentle simmer and cook for 6–8 minutes, stirring occasionally, until it thickens slightly and the flavors meld.
5. Add basil and adjust seasoning: Tear in the 2 basil leaves and stir them into the sauce. Taste the sauce and season with sea salt and freshly cracked black pepper as needed. Remember that the olives and capers are salty, so start with a light hand and add more if needed.
6. Fold in the tuna: Gently add the 280 g canned tuna chunks to the simmering sauce. Use a spatula to fold the tuna into the sauce in large flakes; avoid over-stirring so the tuna keeps some texture. Cook for 1–2 minutes just until the tuna is heated through and incorporated.
7. Combine pasta and sauce: Add the drained spaghetti directly to the skillet with the sauce, or return the pasta to the pot and pour the sauce over it. Toss carefully to combine, adding some reserved pasta cooking water a splash at a time to loosen the sauce and help it cling to the noodles. You may not need the full cup; use enough to achieve a glossy, saucy coating.
8. Finish and serve: Remove the pan from the heat. Sprinkle 2 tablespoons fresh parsley over the pasta and toss once or twice to distribute. Taste and adjust final seasoning with sea salt and freshly cracked black pepper if necessary. Divide the pasta among serving plates and garnish with any extra parsley, a drizzle of extra-virgin olive oil, or a fresh basil leaf, if you like.

Troubleshooting and Tips

• If the sauce seems too acidic, add a pinch of sugar or a small knob of butter to round it out.
• Reserve pasta water is gold: the starchy liquid helps the sauce cling to the spaghetti and creates a silky finish.
• Don’t over-flake the tuna when you add it; larger flakes give better texture than fully mashed tuna.
• Adjust salt at the end. Olives and capers carry a lot of salt, so it’s easier to add than to subtract.
• For more brightness, finish with a squeeze of lemon juice right before serving.

Make-ahead and storage

This dish is great for leftovers. Store any cooled pasta in an airtight container in the refrigerator for up to 3 days. When reheating, loosen with a splash of water or a little extra olive oil and warm gently on the stovetop to preserve texture. For best results, reheat just until warmed through; overcooking will dry the tuna and make the pasta mushy.

Variations and swaps

• Vegetable-forward: stir in quick-sauteed spinach or chopped roasted peppers for an added veggie boost.
• More herbs: fresh oregano or a sprinkle of chopped chives adds a different herbal note.
• Smokier flavor: use smoked olives or add a small pinch of smoked paprika to the sauce.
• Make it lighter: swap half the pasta for zucchini ribbons and toss them briefly in the sauce just before serving.
