Spaghetti allo Scoglio is a classic Italian seafood pasta dish, loved across Italy. This flavorful recipe features a mix of fresh shellfish—mussels, clams, shrimp, and squid—cooked in a light cherry tomato sauce that brings out the taste of the sea.
You can use spaghetti, as I did, or go for linguine, which also pairs beautifully with seafood sauces. In Southern Italy, especially in Neapolitan cuisine, paccheri is another popular option for this dish.
Although it’s an easy recipe, Spaghetti allo Scoglio requires a bit of time and patience—mainly to clean the seafood and prep all the ingredients. The key steps? First, purge and cook the clams and mussels. Then, clean the shrimp and squid.
Once your seafood sauce is ready, the secret to achieving restaurant-quality flavor is to finish cooking the pasta in the sauce. This helps the pasta absorb all the delicious seafood juices and aromas.
This traditional Italian seafood spaghetti is perfect year-round—from summer dinners with friends to Christmas Eve family meals. It’s a simple yet impressive dish, ideal for anyone who loves seafood and Mediterranean flavors.
Ingredients
Prep Time: 30 Min + about 1 hour to purge the clams | Cook Time: 20 Min | Servings: 4
- 350 g (12 oz) spaghetti
- 1 kg (2 pound) fresh clams, in their shells
- 1 kg (2 pound) fresh mussels, in their shells
- 300 grams (⅔ pound) squid
- 300 g (⅔ pound) shrimp

- 2 garlic cloves
- 5 tablespoons extra virgin olive oil
- 150 ml (½ cup ) dry white wine

Kitchen Tools and Equipment
- A very fine mesh strainer is essential to filter the water of the clams and mussels. We opted for this professional super fine mesh strainer with strengthened non slip handles.
- Even a large and low pot is important because it must contain both the sauce and spaghetti, that will have to finish cooking in the seafood sauce. So have a look to this stainless steel dutch oven casserole with lid.
- Very useful to drain spaghetti directly into the pan to continue cooking, is this silicone spaghetti strainer.
- Finally, another useful tool in the preparation of this recipe is an electric chopper to chop fresh parsley which is the final touch of your Spaghetti allo Scoglio.
Instructions
To prepare this Italian seafood pasta recipe, start by cleaning the clams and mussels. Then clean squids and shrimps. Here's how you need to do it:
Clean and Cook the Clams
Step 1) - Rinse clams under running water and then let them soak in plenty of cold water with a handful of coarse salt.
The clams should remain in the cold water for at least an hour, preferably two, to purge. Keep this time in mind when you decide to make this recipe.
Place the clams in a pan and cook over high heat covered with a lid. Wait for them to open, this will take about 3 minutes.
Step 2) - Now strain the clam sauce with a fine strainer but DO NOT throw away their water, keep it aside.
Finally shell the clams, keeping some clams with their shells that you will use for the final decoration of the dish.
Clean and Cook the Mussels
Step 1) - Clean the mussels by scraping off any impurities with the blade of a small knife. Tear off the byssus, that is the bearded part that comes out of the shell. Then, with the help of a stainless steel sponge, clean well their shells.
Place the mussels in a pan and cook over high heat covered with a lid. Wait for them to open, this will take about 3 minutes.
We prefer to cook clams and mussels separately in case the clams release a lot of sand.
Step 2) - Now strain the mussels sauce with a fine strainer. Finally shell the mussels, keeping some of them with their shells: you will use them for the final decoration of the dish.
Clean the Squid
Step 1) - Wash the squid under running water, then remove the entrails, the eyes, the central beak and the internal bone.
Step 2) - Finally remove the skin and cut them into rings. Set aside.
Clean the Shrimps
Clean the shrimps, taking care to remove the dark filament, all the shell and the heads. Set aside.
Now that you have prepared and cleaned all the seafood, let's see how to make the sauce for the spaghetti allo scoglio.
The Seafood Sauce
Step 1) - Wash and chop the cherry tomatoes then chop the parsley. Set aside.
Step 2) - In a large saucepan, sauté the peeled garlic cloves in the extra virgin olive oil. Add the red hot chili pepper and the squid. Cook for about 2 minutes over medium heat.
Step 3) - Then raise the heat and add the white wine. Stir and allow the alcohol to evaporate. Finally add the mussels and clams and lower the heat.
Step 4) - Add a ladle of clams water and then the chopped tomatoes. Mix and cook over high heat for about 10 minutes.
Step 5) - Finally, add the shrimp and chopped parsley. Cook over medium heat for about 3 minutes (shrimp have very short cooking times).
Italian seafood sauce is ready. Remove the garlic cloves and chili pepper (see note below).
Cook the Pasta
Step 6) - Now cook the pasta. Bring plenty of salted water to a boil. Cook the spaghetti according to the cooking times described on their packaging. Using a slotted spoon, drain the spaghetti 3 minutes before the end of cooking time.
Season and Serve
Step 7) - Place them directly in the pan with the seafood sauce. Stir and finish cooking the spaghetti in the pan for another 3 minutes over high heat. This way they will better absorb the flavor of the seafood sauce.
Stir well and transfer the best Spaghetti allo Scoglio you have ever eaten to a serving dish. Garnish with the shells kept aside and serve.
NOTE ABOUT GARLIC AND HOT CHILI PEPPER: We chose to leave the garlic and hot chili pepper whole. This way you can easily remove them from the sauce. If you prefer, though, you can chop them up and leave them in the sauce, depending on your taste.

Storage
Enjoy your spaghetti allo scoglio immediately and if there is any left over, it can be stored in the refrigerator in a food container for up to 1 day.
I do not recommend freezing. However, you can freeze the seafood sauce if you have used fresh ingredients.
TOMATO OPTIONS: I used cherry tomatoes, but you can also use ripe grape or vine tomatoes. If fresh tomatoes aren't available, canned peeled tomatoes or tomato passata work well too. Just remember to cook the sauce longer before adding the seafood, as canned tomatoes need more time to develop flavor.
SPAGHETTI ALL SCOGLIO "IN BIANCO" (WITHOUT TOMATOES): This tomato-free version is very popular in Italy. The method is the same—just skip the tomatoes. It enhances the natural seafood flavor, so use the freshest shellfish possible. Add a bit more olive oil, parsley, and clam juice for extra richness.
SEAFOOD VARIATIONS: You can add or swap in scampi, octopus, or other seafood based on your taste. The key is to include a mix of mollusks, crustaceans, and shellfish for a balanced Italian seafood pasta.
USING FROZEN SEAFOOD: While fresh seafood is best, frozen fish is a good alternative. Thaw it completely before following the recipe as usual.
EXTRA FLAVOR TIP: Using whole shrimp? Sauté the heads with garlic at the start to boost the flavor of your seafood spaghetti sauce. Just remove them before serving.
SCOGLIO VS PESCATORA: “Pasta allo Scoglio” and “Pasta alla Pescatora” are often used interchangeably, but there's a difference.
- Spaghetti allo Scoglio includes only shellfish and crustaceans—no fish fillets.
- Pescatora typically excludes shell-on mollusks and may include fish like sea bass or swordfish.
Both are delicious variations of Italian seafood pasta, and both can be made with or without tomatoes, usually paired with spaghetti or linguine.
