One-pot pasta puttanesca brings spaghetti, tomatoes, olives, capers, garlic, and anchovies together in a savory, briny sauce. The pasta cooks right in the pan, so its starch helps thicken the sauce and there is only one pot to wash. It is a practical weeknight dinner with punchy flavor and no need to boil pasta separately.
Ingredients
- 12 ounces (340 g) dried spaghetti, broken in half if needed to fit the pot
- 2 tablespoons extra-virgin olive oil
- 4 anchovy fillets, finely chopped, or 1 tablespoon anchovy paste
- 4 garlic cloves, thinly sliced
- ¼ teaspoon red pepper flakes, or more to taste
- 1 can (28 ounces/794 g) crushed tomatoes
- 4 cups (950 ml) water, plus a little more if needed
- ½ cup (75 g) pitted Kalamata or other brined black olives, halved
- 2 tablespoons capers, drained and rinsed if especially salty
- ½ teaspoon fine salt to start, plus more to taste
- ¼ teaspoon freshly ground black pepper
- 2 tablespoons chopped fresh parsley, plus extra for serving
- 1 teaspoon finely grated lemon zest, optional
Instructions
- Start the flavor base. Choose a wide, heavy pot or deep sauté pan large enough to hold the spaghetti. Set it over medium heat and add the olive oil and anchovies. Cook for 1 to 2 minutes, stirring and pressing the anchovies with a spoon until they mostly dissolve into the oil. They should melt into the sauce rather than become crisp.
- Cook the garlic and pepper. Add the sliced garlic and red pepper flakes. Stir for about 30 seconds, just until fragrant. Do not let the garlic turn dark brown; burnt garlic can make the whole dish bitter.
- Add the pasta and liquid. Pour in the crushed tomatoes and water, then add the spaghetti, olives, capers, salt, and black pepper. Push the strands down and spread them out as much as possible. Some spaghetti may stick above the liquid at first; that is fine as long as you begin stirring promptly as it softens.
- Simmer, stirring often. Bring the mixture to a boil, then reduce the heat to maintain a steady, uncovered simmer. Stir frequently, especially along the bottom and around the edges, separating strands as they soften. Cook for the time on the pasta package, usually 10 to 12 minutes, or until the spaghetti is al dente. If the pot looks dry before the pasta is tender, add hot water ¼ cup at a time. If it is still very soupy at the end, simmer for another minute or two while stirring.
- Finish and serve. Turn off the heat when a little loose sauce remains; the pasta will absorb more as it rests. Stir in the parsley and lemon zest, if using, and taste before adding more salt because olives, capers, and anchovies are already salty. Rest for 2 minutes, then toss again and serve hot.
Tips
- Stir more often than you would with separate-pot pasta. Pasta releases starch directly into the sauce, which is useful for body but can settle and stick. Use a broad spoon or tongs to scrape the bottom and loosen strands throughout cooking.
- Salt carefully. The salty ingredients vary by brand. Starting with just ½ teaspoon of salt gives you room to adjust after cooking; rinse capers if they taste intensely salty.
- Keep extra hot water nearby. Spaghetti shape, pot width, and simmer strength affect how quickly liquid evaporates. Add small amounts only when needed rather than pouring in extra water at the start.
- Use a wide pot if possible. A wide base lets the spaghetti lie flatter and cook more evenly. If using a narrower pot, break the pasta in half and stir frequently until it is fully submerged.
Serving Suggestions
Serve the pasta as soon as it is ready, while the sauce is glossy and loose. A simple green salad with lemon vinaigrette balances the salty, robust sauce, and steamed broccoli or sautéed greens make an easy vegetable side. Offer crusty bread for swiping up any sauce left in the bowl. A little extra parsley, a drizzle of olive oil, or finely grated Parmesan is optional; Parmesan is not essential to puttanesca and can make the dish saltier.
Variations
For a milder dish, reduce the red pepper flakes or leave them out. For more heat, add another pinch; let the flakes sizzle briefly in the oil, but do not scorch them. If you do not eat anchovies, omit them and add a teaspoon of soy sauce or a small splash of olive brine for savory depth, adjusting salt at the end. To make the dish vegetarian, check that the olives and other ingredients are suitable and use the soy sauce option.
You can use bucatini, linguine, or another long dried pasta, but cooking time and liquid needs may vary. Short pasta such as penne also works, though it may need a little longer and more frequent stirring. For a vegetable addition, stir in a handful of baby spinach during the final minute. Avoid adding a large quantity of watery vegetables without adjusting the liquid, since they can change the cooking balance.
Storage and Reheating
Refrigerate leftovers in a covered container within 2 hours of cooking. They keep well for 3 to 4 days at 40°F (4°C) or colder. The pasta will continue to absorb sauce as it cools, so it may be thicker the next day. Reheat a portion in a saucepan over medium-low heat with 1 to 2 tablespoons of water, stirring until steaming hot throughout. In a microwave, cover loosely and heat in short intervals, stirring between them; add a splash of water if needed. Reheat only the amount you plan to eat, and do not leave cooked pasta at room temperature for more than 2 hours (1 hour if the room is hotter than 90°F/32°C).
Frequently Asked Questions
Do I need to cook the pasta separately?
No. The spaghetti cooks in the tomato-and-water mixture, which saves a pot and gives the sauce a silky texture from the pasta starch. Keep the pot at a steady simmer and stir often so the strands cook evenly.
Can I use a different kind of pasta?
Yes. Dried long pasta is the closest match, while short shapes are easier to stir but may take a different amount of time. Check the package timing and begin testing for doneness a couple of minutes before it is due; add hot water in small amounts if the pasta is not tender and the pot is nearly dry.
Will the dish taste fishy if I use anchovies?
Not usually. As they warm in the oil, anchovies break down and contribute savory depth rather than a distinct fish flavor. If you are sensitive to them or need a vegetarian version, omit them and add a little soy sauce or olive brine instead.
Why is my sauce too watery or too thick?
Liquid can evaporate at different rates depending on the pot and heat. If the pasta is cooked but the sauce is thin, simmer briefly while stirring. If the pasta is still firm and the mixture has dried out, add hot water ¼ cup at a time until it can finish cooking.
Can I make this ahead?
It is best freshly cooked because the spaghetti absorbs sauce as it sits. You can chop the garlic and parsley, measure the olives and capers, and open the tomatoes ahead. For leftovers, refrigerate promptly and loosen the pasta with water when reheating.
