A seafood extravaganza popular throughout Italy’s coastal regions where fresh seafood is plentiful! This dish is called Spaghetti allo Scoglio in Italian, which means spaghetti ‘on the rock‘ because it features several mollusks that live ‘on the rock’ (allo scoglio) such as clams and mussels.
In the video recipe below, Italian Grandma demonstrates how to make the Seafood Spaghetti recipe she makes for her family on special occasions. Grandma Lulu even adds something extra special she found at the grocery: mantis shrimp! However, feel free to leave them out since they are not that easy to come by.

How to Make Seafood Spaghetti: Tips
The ultimate Italian Seafood Pasta recipe! Spaghetti with clams, mussels, calamari, squid, shrimp and scampi— a seafood lover’s dream! This dish is popular year-round wherever and whenever fresh seafood can be found. It’s a rich and delicious special occasion dish which is often served on Christmas Eve when Italians don’t eat meat.
Sometimes called Seafood Marinara Pasta abroad, this is the definitive seafood pasta recipe! Rich in shellfish (mussels and clams) as well as squid, calamari and shrimp, this pescatarian recipe has it all.
Save time and money? Buy clam juice and frozen or shelled shellfish.
To save money or time, use pre-prepared shellfish meat and clam juice instead of buying the shellfish fresh in the shell.
We think our Italian Grandma’s recipe is the best —and think you’ll agree— but feel free to adjust the quantities of seafood or leave something out if you prefer.
Strain the seafood broth.
Even shellfish that have been rinsed well can sometimes have sand in them that comes out while steaming.
To avoid ruining your savory seafood broth with grains of sand, be sure to strain the broth into a bowl before adding it to the seafood pasta sauce.
Use products made from San Marzano tomatoes.
To find the best quality tomato purée, look for products that say they are made with San Marzano tomatoes. These tomatoes are world-renowned for being sweet and flavorful.
Don’t over salt!
Remember that seafood broth is naturally salty. When the recipe says to add a pinch of salt, we really do mean just a pinch! It’s better to add little to no salt during the cooking process. Then, taste after the shellfish broth has been added to see if extra salt is needed.

“I have eaten versions of this from many Italian Nonnas starting with my own as a boy and this one is true perfection. We don’t commonly have mantis shrimp here in the States but sometimes I do use Langoustines and Bay Scallops to the mix. Or whatever I can find that is fresh and of best quality..
Bravo Nonna Lulu & bellissimo. ! 😋😍🤩😋”
