There are certain foods that I love making vegan versions of – and alfredo is one of those foods.

This is the recipe you can feed to your carnivore friends and play that “I-can’t-believe-this-is-vegan” game.

We all know that game.

Whether you are strictly vegan or just looking for a lightened up alfredo, this recipe is for you my friend.

The base is cooked onions and garlic. Then cashews and plant-based milk are added for creaminess, nutritional yeast for cheesiness, and lemon juice for some lightness. Seasoned with salt and pepper, you are left with a decadent vegan alfredo sauce that is the perfect companion for any pasta!

Note: This recipe calls for soaked cashews so there’s a little prep work to remember.

Quick cashew soaking method:

If you forget to soak the cashews OR you just realized you need this recipe in your life right now (which I don’t blame you), you can do the quick soaking cashew method…

  1. Bring a pot of water to a rolling boil.
  2. Remove from heat and pour into a glass or mason jar. Add cashews and let sit uncovered for 15 minutes.

How do you thicken vegan alfredo sauce?

This recipe with soaked cashews and dairy-free milk creates a wonderfully smooth cream sauce. However if after blending you want a thicker vegan alfredo sauce, try adding a bit more nutritional yeast and blend again for a moment. You also can toss in some shredded plant-based parmesan cheese to the blender for added thickness and richness. 

How to use homemade vegan alfredo sauce

Mix your sauce with warm pasta and steamed broccoli (highly recommended) for a delicious dinner. You can use gluten-free pasta if you like!

Alfredo sauce is also yummy served directly over your other cooked veggies or on rice. It’s so good I bet you’ll give it a try on nearly all of your most loved sides! Let me know in the comments your favorite ways to enjoy 🙂

Tip: You can find fancy pasta in the food section at Home Goods which is where I bought this fettuccine. It is wayyyy better than the typical grocery store kind and pretty comparable in price (winning!)

Which plant-based milk is best for this recipe?

Some alfredo recipes call for coconut milk (for extra creaminess). I personally prefer unsweetened almond milk. You can taste the coconut milk in the alfredo sauce and I personally am not a fan. Almond milk is more neutral and lets the other flavors shine through.

Serving Suggestions:

  • fettuccine pasta about 1/2 package uncooked
  • 1 cup steamed broccoli

Alfredo Sauce:

  • 1 Tablespoon olive oil
  • 1 white or yellow onion diced
  • 4 cloves garlic minced
  • 1/4 cup raw cashews soaked in water for at least 4 hours (see notes for quicker method)
  • 3/4 cup plain, unsweetened almond milk
  • 1/2 Tablespoon lemon juice
  • 1 Tablespoon nutritional yeast
  • 1 teaspoon salt
  • 1/2 teaspoon pepper



  • Heat olive oil in a pan on low- medium heat.
  • Sauté onions until translucent (about 10 minutes). Add garlic and cook until fragrant (about 30 seconds).
  • Add to high-speed blender along with remaining ingredients. Taste and adjust seasonings if needed.
  • Cook pasta according to instructions. To steam the broccoli, I like to put a wire mesh strainer over the pot of pasta and add the broccoli. Steam until bright green.
  • Combine cooked pasta, broccoli, and sauce. Serve warm. Leftovers keep in the fridge for about 5 days.



If you don't have time to soak cashews, use the quick method:
  1. Boil a pot of water to a rolling boil.
  2. Pout water into glass or mason jar and add cashews.
  3. Let sit uncovered for 15 minutes.
Homemade dairy-free vegan alfredo sauce will keep well for up to 4 days stored in a sealed container in the fridge, and is easy to reheat in the microwave. Just stir between short bursts until slightly warm, and then add to hot pasta or veggies.
