Step 1
- a.Cook the Pasta
- b.Bring a large pot of water (at least 4 quarts) to a rolling boil.
- c.Add 2 tablespoons of salt to the water. It should taste salty like the sea.
- d.Add the spaghetti and cook according to package directions until al dente, typically 8-10 minutes.
- e.Just before draining, use a mug or heatproof measuring cup to reserve at least 1.5 cups of the starchy pasta water. This is crucial for the sauce.

Step 2
- a.Prepare the Butter Sauce
- b.While the pasta is cooking, melt the butter in a large skillet or pan over medium-low heat.
- c.Add the thinly sliced garlic and cook for 1-2 minutes, swirling the pan, until fragrant. Be careful not to let the garlic brown or it will become bitter.

Step 3
- a.Emulsify the Sauce
- b.Using tongs, transfer the cooked pasta directly from the pot into the skillet with the garlic butter. A little water clinging to the pasta is good.
- c.Remove the skillet from the heat. Add the grated Parmesan cheese and about 1/2 cup of the reserved pasta water.
- d.Immediately begin tossing the pasta vigorously with tongs. The combination of hot pasta, butter, cheese, and starchy water will emulsify into a creamy, glossy sauce that coats every strand.
- e.Continue tossing for 1-2 minutes, adding more pasta water a tablespoon at a time if the sauce seems too thick or dry, until you reach your desired consistency.

What to keep in mind.
4 tips from the recipe — small details that make a real difference to the final dish.
- 1Use high-quality Parmigiano-Reggiano cheese and grate it yourself. Pre-shredded cheese contains anti-caking agents that prevent it from melting into a smooth sauce.
- 2Do not drain the pasta water down the sink! Reserving the starchy water is the most important step for creating a creamy, emulsified sauce without any cream.
- 3Work quickly once the pasta is in the skillet. The sauce comes together in just a minute or two and is best served immediately while hot and creamy.
- 4Use a large skillet or pan for tossing. This gives you enough room to toss the pasta vigorously, which is key to creating a well-emulsified sauce.
