Can I make spaghetti alla puttanesca without sardines?
Yes. Substitute with anchovy fillets (milder flavor), canned tuna, or omit entirely for a vegetarian version. The sardines provide umami and briny depth, so reduce salt if removing them.
What's the difference between puttanesca and other Italian pasta sauces?
Puttanesca is defined by briny, salty elements—olives and sardines or anchovies—plus red pepper flakes for heat. It's less creamy and more assertively flavored than marinara or aglio e olio.
How do I prevent the sauce from becoming too salty?
Taste as you build the sauce. Sardines and olives are naturally salty, so add salt gradually and taste before serving. Use unsalted marinara if possible.
Can I prep this dish ahead?
Make the sauce up to 2 days ahead and refrigerate. Cook spaghettini fresh and toss with reheated sauce just before serving for best texture.
What type of olives work best?
Green olives are traditional for puttanesca and provide the characteristic briny, slightly astringent bite. Kalamata olives work but are milder and less authentic.
