First, chop garlic and pepper, shred onion, slice mushrooms, dice tomatoes and soak clams in water for later use.

Boil the water, add the salt, and cook the spaghetti for about 8- 10 minutes (don't cook the noodle core thoroughly). Take it out and put it aside.

Add appropriate amount of cream and stir-fry minced garlic and pepper, then add shredded onion and diced tomato and stir-fry until soft.

In step 3, add appropriate amount of water and tomato sauce, then add mushroom slices and Italian spices, and boil.

Pour the spaghetti into the pot and roll until the soup is almost dry. Add seafood and cook.

Sprinkle shredded cheese on the plate in step 5 and bake in the oven until the cheese melts.
