Bring a large pot of water to a rolling boil over high heat.

Once boiling, add 1 tablespoon of salt to the water. Add the 1 pound of spaghetti to the pot, stirring occasionally to prevent sticking.

Cook the pasta according to package directions until it is al dente (firm to the bite). Before draining, reserve at least 1 1/2 cups of the starchy pasta water.

While the pasta is cooking, melt the 1/2 stick of unsalted butter in a large skillet or pan over medium-low heat.

Once the butter is fully melted, remove the pan from the heat. Add 1 cup of freshly grated Parmigiano cheese to the pan.

Add one ladle (about 1/2 cup) of the reserved pasta water to the pan with the butter and cheese. Stir vigorously with a whisk or spoon to combine thoroughly, creating a smooth, emulsified sauce.

Using tongs, transfer the cooked spaghetti directly from the pot to the pan with the sauce. Do not drain the pasta completely; the residual water clinging to the noodles will help the sauce.
Return the pan to low heat. Add more reserved pasta water, a little at a time (1/4 to 1/2 cup increments), stirring continuously and tossing the pasta until it is evenly coated and the sauce reaches a creamy, desired consistency. This process helps the cheese and butter emulsify and cling to the pasta.

Serve immediately, garnished with an additional sprinkle of fresh grated Parmigiano cheese if desired.
