Cook the noodles according to the instructions on your box, and once they're done drain the noodle water, reserving 2 tbsp, and set aside.
For the garlic butter mixture, heat a saucepan up over medium heat.
Add the butter, and once it starts to sizzle and the pan is hot, add the garlic.
Sautee the garlic in the butter but don't let the garlic get too brown - it should be at the point where you can smell the garlic butter flavour and the garlic pieces are getting translucent - this takes a few minutes.
Add in the 2 tbsp reserved noodle water.
Stir in the salt and pepper.
Add in the noodles and stir them around to incorporate all the ingredients.
Turn off the heat and add the parsley right before serving. This is optional, but I always love adding some toppings onto my noodles.
Enjoy hot!
