Ingredients

Scale

For the Walnut Sauce:

  • 1 cup walnuts, toasted
  • 1 clove garlic, minced
  • ½ cup Parmesan cheese, grated
  • ½ cup heavy cream (or milk for a lighter version)
  • 2 tablespoons olive oil
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • ¼ teaspoon nutmeg (optional, for added depth)
  • ¼ cup reserved pasta water (to adjust consistency)

For the Pasta:

  • 12 ounces pasta (such as linguine, fettuccine, or tagliatelle)
  • 1 tablespoon salt (for boiling pasta water)
  • 2 tablespoons butter (optional, for extra richness)

Instructions

Cook the Pasta

  1. Boil Water: Bring a large pot of salted water to a rolling boil.
  2. Cook Pasta: Add the pasta and cook according to package instructions until al dente.
  3. Reserve Pasta Water: Before draining, save ¼ cup of the pasta water for adjusting the sauce.
  4. Drain and Set Aside: Drain the pasta and return it to the pot.

Prepare the Walnut Sauce

  1. Toast the Walnuts: In a dry pan over medium heat, toast the walnuts for 3–4 minutes until fragrant.
  2. Blend the Sauce: In a food processor or blender, combine the toasted walnuts, garlic, Parmesan, olive oil, heavy cream, salt, pepper, and nutmeg. Blend until smooth.
  3. Adjust Consistency: Add reserved pasta water little by little until the sauce reaches your desired creaminess.

Combine and Serve

  1. Mix with Pasta: Pour the walnut sauce over the drained pasta and toss to coat evenly.
  2. Add Butter (Optional): For extra richness, mix in 2 tablespoons of butter while tossing the pasta.
  3. Garnish and Serve: Top with extra Parmesan cheese, chopped walnuts, and a drizzle of olive oil.
