Silky garlic-chili confit sauce and fresh shellfish coat al dente spaghetti for a classic Italian marinara-style seafood pasta, perfect for a festive dinner.
This seafood spaghetti is built around a silky garlic-chili confit sauce that clings to the noodles. A mix of clams, mussels, shrimp, and tender squid makes it feel celebratory while still approachable for a home cook.
Slow-cooking the aromatics in olive oil creates a sweet, mellow base without harsh bite. Blending the confit with sparkling water helps the sauce emulsify and stay glossy when tossed with pasta and shellfish juices.
Spaghetti is the backbone, while clams and mussels bring briny depth. Shrimp and squid cook quickly at the end for a tender finish, and parsley keeps everything fresh.
Start by making the confit, then open the clams and mussels and save their cooking liquid. Finish the spaghetti in the sauce so it absorbs the flavor, then add shrimp and squid right before serving. Fold the shellfish back in and finish with parsley.
If you cannot find baby squid, sliced large squid or scallops are good alternatives. Leftovers keep for 1 day; reheat gently with a splash of water to avoid overcooking the seafood.
