Step‑by‑Step Instructions for Authentic Italian Seafood Spaghetti with Shrimp and Octopus
Step 1: Prepare the Octopus
In a pressure cooker, combine the octopus with water, a bay leaf, and a pinch of salt. Lock the lid in place and cook on high pressure for 10 minutes. Once the time is up, use the quick-release method to release the steam. The octopus should be tender and easy to slice into bite-sized pieces.
Step 2: Chop and Reserve Liquid
Carefully remove the cooked octopus from the pressure cooker and chop it into small pieces. Set aside the chopped octopus while keeping the flavorful cooking liquid in a separate bowl; this liquid will enhance the sauce later on for your Italian Seafood Spaghetti.
Step 3: Make the Tomato Sauce
In a medium saucepan, drizzle olive oil and add canned whole tomatoes, a handful of fresh basil leaves, and a sprinkle of salt. Simmer the mixture over medium heat for about 20-25 minutes, stirring occasionally. Cook until the sauce thickens and the tomatoes break down, creating a rich, fragrant base for your seafood pasta.
Step 4: Cook the Spaghetti
While the sauce simmers, bring a large pot of salted water to a boil. Add the Italian spaghetti and cook according to the package instructions until al dente, usually around 8-10 minutes. Once cooked, drain the spaghetti well, reserving a little pasta water just in case you need to adjust the sauce’s consistency later.
Step 5: Sauté the Seafood
In a large skillet, heat a generous amount of olive oil over medium heat. Add minced garlic, allowing it to sauté for about 30 seconds until fragrant. Then, stir in the chopped octopus, shrimp, and mussels, cooking for about 2-3 minutes or until the shrimp turn pink and the mussels begin to open, signaling they are done.
Step 6: Combine Seafood and Sauce
Once the seafood is cooked, pour in the thickened tomato sauce along with the reserved cooking liquid. Stir well to amalgamate everything, letting it simmer for another 2-3 minutes until the mussels are fully opened and the shrimp are tender. This will create a luscious, savory sauce for your Italian Seafood Spaghetti.
Step 7: Add Squid and Toss Spaghetti
Next, gently fold in the cleaned baby squid, allowing it to cook for 1-2 minutes. Then, add the drained spaghetti directly into the skillet, tossing everything together until the pasta is well coated in the sauce. If needed, use the reserved pasta water to loosen the sauce and create a glossy finish.
Step 8: Serve and Garnish
To serve your Italian Seafood Spaghetti, dish out generous portions onto plates, ensuring each has a mix of seafood and spaghetti. Garnish with fresh basil leaves and a drizzle of olive oil. A squeeze of lemon juice over the top adds a refreshing touch that complements the seafood beautifully.

How to Store and Freeze Italian Seafood Spaghetti
Fridge: Store leftover Italian Seafood Spaghetti in an airtight container for up to 2 days. Reheat gently on low heat to preserve the texture of the seafood.
Freezer: You can freeze Italian Seafood Spaghetti for up to 3 months. Place it in a freezer-safe container, but be sure to leave some space for expansion as it freezes.
Reheating: For best results, thaw the spaghetti overnight in the fridge, and reheat on the stovetop with a splash of water to keep it moist. Avoid microwaving for best texture.
Quality Check: If you notice any off smells or changes in texture, it’s best to discard it, especially with seafood dishes. Enjoy the freshness!

Italian Seafood Spaghetti Recipe FAQs
How do I choose the freshest seafood for my Italian Seafood Spaghetti?
Absolutely! When selecting seafood, look for vibrant colors and a fresh, clean scent. The shrimp should be firm to the touch and the octopus should not have any dark spots all over, which can indicate it’s past its prime. If you’re purchasing mussels, they should be closed tightly; any open ones should be gently tapped—if they don’t close, it’s best to leave them behind.
How should I store leftover Italian Seafood Spaghetti?
You can store leftover Italian Seafood Spaghetti in an airtight container in the fridge for up to 2 days. Just reheat on low heat to maintain the texture of seafood, ensuring it doesn’t become tough.
Can I freeze Italian Seafood Spaghetti?
Yes! You can freeze your Italian Seafood Spaghetti for up to 3 months. Here’s how: place it in a freezer-safe container, leaving some space for expansion as it freezes. Make sure to label your container with the date for easy reference later.
What should I do if the sauce is too watery?
Very! If you find your sauce has become too watery, don’t worry! You can use some reserved pasta water to help thicken it. Simply add a little at a time and let it simmer until it reaches your desired consistency. Alternatively, simmer the sauce on medium-low heat until it thickens to your liking.
Are there any dietary considerations I should keep in mind for this recipe?
Of course! If you’re cooking for someone with seafood allergies, you can substitute the seafood with vegetables like zucchini or bell peppers for a vegetarian version. Always ensure to check your ingredient labels for any hidden allergens. Additionally, if you’re serving pets, be cautious as cooked seafood can be harmful to them. Stick with plain, unseasoned leftovers that they might enjoy!
What’s the best way to reheat frozen Italian Seafood Spaghetti?
For the best texture, thaw your frozen Italian Seafood Spaghetti overnight in the refrigerator. When you’re ready to reheat, warm it in a skillet on the stovetop, adding a splash of water to keep it moist. This will help prevent it from drying out. Avoid using the microwave, as it may overcook the seafood and affect the overall quality.
