You need a truly satisfying, creamy vegan alfredo sauce that tastes like the original. This recipe delivers an indulgent, dairy-free white sauce perfect for fettuccine, made without cashews, coconut milk, or cauliflower.

Ingredients

Scale
  • 1 cup firm silken tofu
  • 1 cup unsweetened soy milk (or other neutral plant milk)
  • 4 cloves garlic, minced
  • 1/4 cup nutritional yeast
  • 1 tablespoon lemon juice
  • 1 teaspoon Dijon mustard
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • Pinch of nutmeg
  • 1 pound fettuccine pasta (or gluten-free alternative)

Instructions

  1. Cook the fettuccine pasta according to package directions. Reserve about 1 cup of the starchy pasta water before draining.
  2. While the pasta cooks, prepare the sauce. Combine the silken tofu, soy milk, minced garlic, nutritional yeast, lemon juice, Dijon mustard, salt, pepper, and nutmeg in a high-speed blender.
  3. Blend on high until the mixture is completely smooth and creamy. This may take 1 to 2 minutes, depending on your blender power. Stop and scrape down the sides as needed.
  4. Transfer the sauce to a medium saucepan over medium heat. Heat gently, stirring constantly, until the sauce begins to simmer lightly. Do not boil.
  5. If the sauce is too thick, add the reserved pasta water, one tablespoon at a time, until you reach your desired consistency for a rich, coating sauce.
  6. Toss the drained fettuccine immediately with the hot vegan alfredo sauce until every strand is coated.
  7. Serve your easy plant based alfredo immediately for an indulgent vegan dinner.

Notes

  • For a copycat Olive Garden vegan experience, add 1/2 teaspoon of onion powder to the blender for extra depth.
  • If you prefer a richer flavor, you can sauté the garlic in 1 teaspoon of vegan butter before adding it to the blender.
  • This sauce is naturally gluten free vegan alfredo if you use gluten free pasta.
