Ingredients:

  • 1 lb (450g) spaghetti or linguine
  • 4 qts (3.8L) water
  • 2 tbsp (30g) salt
  • 1/2 cup (115g) unsalted butter
  • 6 cloves (18g) garlic, minced
  • 1/2 cup (120ml) reserved pasta water
  • 1 cup (100g) freshly grated Parmesan cheese
  • 1/4 tsp (1.5g) freshly cracked black pepper
  • 2 tbsp (8g) fresh parsley, chopped

Instructions:

  1. Bring the salted water to a rolling boil. Note: The water should look and taste like the sea.
  2. Add the noodles and cook until al dente, which is usually 1-2 minutes less than the package says.
  3. Before draining, scoop out at least 1 cup of the cloudy pasta water and set it aside.
  4. Melt the butter in a skillet over medium low heat.
  5. Add the minced garlic and sauté for 2-3 minutes until fragrant and translucent. Note: If the garlic turns brown, it'll taste bitter, so keep the heat low.
  6. Pour 1/2 cup (120ml) of the reserved pasta water into the butter and garlic.
  7. Increase heat to medium and whisk for 1 minute until the liquid looks unified and slightly thickened.
  8. Toss the drained noodles into the skillet using tongs.
  9. Turn off the heat completely. Note: This is the most important step to prevent cheese clumping.
  10. Sprinkle in the Parmesan and black pepper, tossing rapidly until the cheese melts into a glossy coating.
  11. Garnish with fresh parsley and serve immediately.
