The Easiest Buttered Noodles (3 Ingredients)

Steps

1. 1

   Bring a large pot of water to a boil and season it generously with kosher salt.

2. 2

   Add the spaghetti and cook according to the package instructions, or until al dente, about 7 minutes. Do not drain it; reserve the cooking water in the pot.

   Start 7-minute timer
3. 3

   While the pasta boils, place half of the cubed butter in a large saucepan over medium-low heat. Once it is slightly melted, turn off the heat and wait for the pasta to finish cooking.

4. 4

   Using tongs, transfer the cooked spaghetti directly from the pot into the saucepan with the melted butter. A little pasta water will come along; it helps emulsify the sauce.

5. 5

   Add the remaining butter. Toss the pasta constantly, adding pasta water one tablespoon at a time until the sauce is fully emulsified, slightly thickened, and clings to the noodles.

6. 6

   Season with kosher salt to taste, then toss again so the pasta is evenly coated.

7. 7

   Serve. If desired, finish with flaky salt and freshly cracked black pepper, taking care not to oversalt.
