Make this vegan pasta recipe for an easy dinner, using just 5 ingredients! Tender pasta with a delicious and smooth garlic walnut sauce. Gluten free with a keto recipe option!



  • 1 cup walnut halves toasted (see notes)
  • 2 garlic cloves (minced or whole)
  • 1/4 cup nutritional yeast or grated Parmesan cheese for non vegan option.
  • 1 tsp dried herbs optional
  • 1/2 c almond milk or non dairy milk
  • salt/pepper, to taste
  • 1 tsp lemon juice
  • 12 ounces gluten free pasta or zoodles (zucchini noodles)
  • fresh basil and crushed walnuts to garnish


  1. Bring a large pot of water to a strong boil. Add salt, followed by pasta. Cook pasta al dente according to package directions.
  2. Set aside 1/4 cup of the pasta water, then drain the pasta and rinse with cold water. Set aside. While pasta is cooking, make the walnut sauce.

For the garlic walnut sauce

  1. Place toasted walnut halves, garlic, parmesan (or nutritional yeast), and herbs in a food processor or high powered blender. Blend until a mealy texture is formed.
  2. Next, set the blender or food processor on low and add in the almond milk. Blend until a creamy thick sauce is formed. If the sauce is too thick, add 2-4 tbsp more milk. Add the salt/pepper and lemon juice, and blend once more.
  3. In the same pot that cooked the pasta (which should still be warm, if not, heat to very low) heat the garlic walnut sauce. Then, mix in pasta or zoodles and 3-4 tbsp of the reserved pasta cooking water to create a creamy sauce. If the sauce isn’t creamy enough to easily coat the pasta, then add in an additional 2 tbsp water and toss again.
  4. Salt and pepper to taste. Spoon into bowls and add fresh basil and crushed walnuts  to garnish.


To dry toast nuts:

Quickly toast the nuts in a hot, dry skillet over medium high heat for 5 minutes, tossing occasionally to prevent the nuts from burning.
