Classic buttered noodles made the right way with just pasta, butter, and optional Parmesan. This simple, comforting recipe focuses on the small details—well-salted water, no rinsing, and a splash of pasta water—for glossy, flavorful noodles that are ready in about 15 minutes.
Bring a large pot of well-salted water to a boil and cook the noodles until al dente. Reserve about ½ cup of the pasta water, then drain the noodles. Do not rinse.
Melt the butter gently in a large skillet over low heat.
Add the drained noodles to the skillet and toss to coat, adding a splash of pasta water as needed until the noodles are glossy and evenly coated. Finish with Parmesan, if using, and season with salt to taste. Serve immediately.
Notes
Salt the pasta water well. This is where most of the flavor comes from, your noodles should taste seasoned before the butter is added.
Do not rinse the noodles. Rinsing removes the starch that helps the butter cling to the pasta.
Save some pasta water. A splash helps emulsify the butter and coat the noodles evenly instead of making them greasy.
Melt the butter gently. You want it melted, not browned, to keep the flavor clean and classic.
Easy upgrades: Add garlic butter, lemon butter, or a sprinkle of Parmesan for extra flavor without changing the simplicity of the dish.
