Fill a large pot with water and 1 tablespoon kosher salt to only 3 inches high and bring to a boil. Once boiling, cook pasta to al dente and make sure to reserve at least 1 cup of the very starchy pasta water.
While pasta is boiling set up a large bowl with the butter, grated cheese, and cream.
Place the al dente pasta into the bowl along with a ladle of pasta water. Toss quickly to melt the butter and cheese. If too dry, add more of the reserved pasta water a bit at a time to get the perfect creamy consistency.
Season with salt to taste and serve immediately.
