Bring a large pot of water to a boil and add pasta. Cook until al dente. Drain pasta, making sure to reserve 1 cup of the water.
Return the pot back to the stove over medium heat. Add the butter and garlic and cook for 1 minute, stirring frequently. Add pasta, pepper, salt and parmesan to the pot. Slowly add pasta water and toss until the ingredients are combined and the sauce forms - it will take a couple minutes. Taste and adjust seasonings.
Serve pasta with chopped parsley and additional parmesan.
