In a saucepot, heat your stove to medium-high heat, add some water and let your udon boil and separate.
Once the udon noodles are cooked, strain them, rinse them with cold water and put them aside.
Place your empty pot back on the burner and add in your butter, garlic, sesame oil, and soy sauce.
Now that your sauce has come together add in your seafood and parsley flakes and let it cook for a few minutes. Don't overcook as seafood gets gummy!
Lastly, put your udon noodles back in and coat the noodles in the sauce.
Serve and enjoy!
