3.9 from 80 reviews

Walnut Sauce, or Salsa di Noci, is a creamy, flavorful Italian sauce made primarily from walnuts, milk, garlic, parmesan cheese, and olive oil. This rustic yet elegant sauce is perfect for tossing with pasta or gnocchi, offering a rich texture and nutty flavor enhanced by reserved pasta water. It’s quick to prepare using a food processor and can be made ahead and stored in the refrigerator, making it a convenient and delicious addition to any meal.

  • Total Time: 10 minutes
  • Yield: 4 servings

Ingredients

Walnut Sauce Ingredients

  • 1.5 cups walnuts (150g)
  • ¾ cup milk (150ml)
  • 1 slice white bread, crusts removed
  • 1 clove garlic
  • 1 cup freshly grated parmesan cheese (50g)
  • 1 tbsp extra virgin olive oil

Instructions

  1. Soak Bread: Cut the crusts off the white bread and place the slice in a bowl with the milk to soak for a few seconds, softening it for blending.
  2. Combine Ingredients: Add the soaked bread and milk along with walnuts, garlic, parmesan cheese, and olive oil to a food processor.
  3. Blend Sauce: Blitz all ingredients together until the mixture is thick but smooth. If the sauce appears too thick, gradually add more milk to achieve the desired consistency.
  4. Reserve Pasta Water (optional): If preparing to toss with pasta or gnocchi, reserve 1 cup (240ml) of pasta cooking water.
  5. Toss with Pasta: After draining the pasta or gnocchi, return it to the pot and add the walnut sauce. Use some of the reserved pasta water to loosen the sauce and toss it together gently. You won’t need the entire cup of pasta water; add gradually until you reach the perfect consistency.
  6. Serve and Garnish: Serve the pasta topped with extra chopped walnuts for added texture and optionally garnish with fresh parsley for a burst of freshness.

Notes

  • The sauce can be prepared in advance and stored in the refrigerator covered with plastic wrap to preserve freshness.
  • If the sauce is too thick, add more milk to reach the desired smoothness.
  • When mixing with pasta or gnocchi, reserving some pasta cooking water helps thin the sauce naturally and adds flavor.
  • Extra chopped walnuts on top add a delightful crunch.
  • Fresh parsley is a wonderful garnish for added brightness and color.
  • Recommend using extra virgin olive oil for the best flavor in this and all recipes.
