Ingredients:

  • 1/2 cup (115g) unsalted butter
  • 1 cup (240ml) heavy cream
  • 1 1/2 cups (150g) freshly grated Parmesan cheese
  • 3 cloves (15g) garlic, minced
  • 1/4 tsp (1.5g) ground nutmeg
  • 1/2 tsp (3g) kosher salt
  • 1/4 tsp (1g) cracked black pepper

Instructions:

  1. Melt the butter over medium low heat. Once foaming, add the minced garlic and sauté for about 60 seconds until fragrant but not brown. Note: Browned garlic becomes bitter.
  2. Pour in the heavy cream and stir in the ground nutmeg.
  3. Increase the heat slightly to bring the mixture to a gentle simmer for 3–5 minutes until it reduces slightly and thickens.
  4. Turn the heat to the lowest setting or remove the pan from the heat entirely. Note: This is the most critical step to prevent the cheese from separating.
  5. Gradually whisk in the freshly grated Parmesan cheese, one handful at a time.
  6. Whisk vigorously until the sauce is glossy and uniform.
  7. Stir in the kosher salt and cracked black pepper.
  8. If the sauce is too thick, whisk in a tablespoon of reserved pasta water until the consistency is velvety.
