Step-by-Step Instructions
1. Cook the Pasta
Bring a large pot of salted water to a boil. Add spaghetti and cook according to package instructions until al dente. Reserve about ½ cup of pasta water before draining.
2. Sauté the Aromatics
While pasta cooks, heat olive oil in a large skillet over medium heat. Add the garlic (and onion, if using) and sauté gently until fragrant and translucent—about 2-3 minutes. Avoid browning the garlic to keep a delicate flavor.
3. Add Tuna and Seasonings
Flake the drained tuna into the skillet. Stir in capers, olives, and chili flakes if using. Cook for 2-3 minutes, allowing the flavors to meld.
4. Combine Pasta and Sauce
Add the cooked spaghetti directly into the skillet with the tuna mixture. Toss to combine, adding reserved pasta water little by little to loosen the sauce and help it coat the pasta evenly.
5. Final Touches
Stir in lemon zest, fresh parsley, and a squeeze of lemon juice. Season with salt and pepper to taste.
