If you love both Italian and Japanese cuisines, Japanese-Style Seafood Spaghetti is a must-try. This unique fusion dish combines the rich, savory flavors of seafood with the light, delicate touches of Japanese ingredients, creating a truly unforgettable pasta experience. It’s a perfect balance of umami and freshness, with seafood taking center stage in a light, flavorful sauce.
At the heart of this dish are the fresh, tender seafood ingredients. You can use a variety of seafood such as shrimp, mussels, scallops, and squid, or whatever is in season or available. These ingredients are sautéed to perfection, bringing out their natural sweetness and brininess.
The magic of this Japanese-style spaghetti lies in its sauce. Instead of using a heavy tomato-based sauce or a traditional Italian garlic and olive oil dressing, this dish uses a combination of soy sauce, mirin (a sweet rice wine), and a touch of sake. These ingredients create a light but flavorful sauce that enhances the seafood without overpowering it. A dash of sesame oil adds an extra layer of depth, and a little grated ginger provides a subtle zing, brightening the overall dish.
The spaghetti itself is cooked al dente, and then tossed with the seafood and the umami-rich sauce. The noodles absorb the sauce, making each bite flavorful and satisfying. To elevate the dish, a sprinkle of toasted sesame seeds, sliced scallions, and a touch of chili flakes can be added for extra texture and a hint of heat.
This Japanese-style seafood spaghetti is perfect for a light dinner or a special meal that’s sure to impress. It offers a beautiful combination of flavors and textures — the sweetness of the seafood, the depth of the soy-based sauce, and the chewy pasta that ties it all together.
In summary, Japanese-Style Seafood Spaghetti is a delightful fusion dish that brings the best of both worlds. It’s simple, flavorful, and packed with fresh seafood and umami-rich ingredients, offering a perfect balance of Italian comfort and Japanese elegance.

Yummm! My family devoured this. The flavors were on point. Definitely gonna make this again! ❤️
Seasfood? 🤮 I prefer my spaghetti with meatballs. But to each their own, I suppose.
I don’t know about this… seafood in spaghetti? Sounds weird. But my friend loved it, so who knows?
I tried this recipe but didn’t have soy sauce, so I used BBQ sauce. It was still kinda good, but not what I expected.
Wow, this is a great twist on spaghetti! I added some chili flakes for a kick and it was delish!
Sounds amazing! I love the idea of adding chili flakes. Definitely gonna try this recipe.
