Add the finely chopped garlic, oyster sauce, sesame oil, brown sugar, soy sauce, stock and water to the instant pot. Whisk together.
Break the spaghetti in half and spread out in layers (see video). Push down carefully into the liquid.
Set the instant pot on high pressure for 4 minutes. Allow to remain under pressure for 4 more minutes and then perform a quick release.
Separate the spaghetti whilst the sauce thickens.
Serve and enjoy
