If you love creamy pasta, but you’d rather not use heavy cream and loads of Parmesan, this dairy-free alfredo is a satisfying alternative. No store-bought vegan cheese is required, so you may already have most of the ingredients you need in your pantry.

It comes together quickly while you wait for the pasta to cook, so it’s a fast weeknight meal that tastes a lot more decadent than it really is. (Really!)

Whether you’re vegan or not, it’s a delicious recipe to try when you want a luscious sauce that’s higher in fiber, lower in fat, and naturally dairy-free.

Vegan Alfredo Sauce Ingredients

  • Cashews. Use unroasted and unsalted cashews for the most mild, neutral flavor. These are softer than other nuts, so they break down into a creamy sauce easily in the blender.
  • Onion. Sauteed onion helps boost the flavor and creates a silkier sauce when blended with cashews.
  • Garlic. A key flavor in any good Alfredo sauce. I use four medium-sized cloves in my recipe, but you can add more or less to your liking.
  • Lemon Juice + Vinegar. The combination of these two tangy ingredients creates a cheese-like flavor without relying on nutritional yeast.
  • Salt + Pepper. These two spices are crucial for the perfect flavor.

How to Make Dairy-Free Alfredo Sauce

Step 1:

If you plan on serving this sauce with pasta, bring a pot of salted water to a boil. Use gluten-free pasta, if you need to. By the time the noodles are done cooking, your vegan cashew alfredo sauce will be ready to use.

Add olive oil or vegan butter to a large skillet over medium heat and saute the onions until they start to soften and look translucent, about 8 minutes. Add in the minced garlic and stir for 1 more minute.

Step 2:

Transfer the cooked veggies to a high-speed blender, then add in the cashews, water, lemon juice, vinegar, salt, and black pepper.

Blend until the sauce reaches your desired consistency. Keep in mind that it will thicken when you toss it with pasta in a hot pan.

Step 3:

When the pasta is done cooking, drain the noodles, then return them to the large pot. Pour the creamy Alfredo sauce over the top, and toss well. (This can also be served over zucchini noodles, for a veggie-packed option.)

Taste and adjust the seasoning to your liking. I usually add more salt and black pepper, to make the flavor pop!

Serving Tips

If the sauce still doesn’t taste like Alfredo, you probably haven’t used enough salt. (Parmesan cheese is very salty, so we’re trying to mimic that here.)

Once you’re happy with the flavor, serve warm with any add-ins you love, like roasted broccoli, peas, crispy mushroom bacon, or other vegetables.

Storage Tip

Leftovers can be stored in an airtight container in the fridge for up to 5 days. Or you can freeze it for up to 3 months.

Dairy-Free Alfredo Sauce Recipe FAQs

Can I use almonds instead of cashews?

Almonds won’t blend quite as smoothly as cashews, but if you want to give that a try, use blanched almonds (with no skins) for a similar effect. 

Do I have to soak the cashews before blending?

As long as you have a high-speed blender, it’s not necessary to soak the cashews first. If you have a standard blender, soaking the cashews may help them soften up, or you can blend the dry cashews first before adding in the other sauce ingredients for easier blending. 

Can I use another liquid for blending?

Using water gives you full control of the final flavor, but you can use vegetable broth or non-dairy milk, like soy milk or almond milk, if you prefer.

This dairy-free Alfredo sauce is one of the best creamy pasta sauces I've ever made. It tastes remarkably like the real thing, despite not using heavy cream or Parmesan cheese. Instead, it relies on a few common kitchen staples, so you may already have everything you need to make it! Once you taste it, you may never need the traditional version again.

Servings:6

Ingredients
 
 

  • 1 tablespoon olive oil
  • 1 small yellow onion , chopped
  • 4 garlic cloves , minced
  • 1 cup whole cashews (not roasted or salted)
  • 1 cup water
  • 1 tablespoon fresh lemon juice
  • 1 teaspoon apple cider vinegar
  • 1 ½ teaspoons fine sea salt (I use Real Salt brand)
  • ½ teaspoon ground black pepper

Instructions

  • Heat the olive oil in a skillet over medium-high heat and saute the onion until it's soft and translucent. This should take 5 to 8 minutes. Add in the garlic and stir until fragrant, about 1 more minute. Remove from the heat.
  • In a high-speed blender, combine the cashews, water, lemon juice, vinegar, salt, and pepper. Add the sauteed onions and garlic, then blend until very smooth. The sauce should look creamy, without any visible chunks of cashews.
  • Serve this alfredo sauce over your favorite cooked pasta, then adjust any seasoning to taste. The noodles will dilute the flavor of the sauce, so you may need to add more salt and pepper, as needed. (This recipe makes enough to coat one pound of pasta.) Leftover sauce can be stored in an airtight container in the fridge for up to 5 days.

  1. This is one of my go to meals when I don’t have time to make a big meal. It’s so good and filling and so easy!!

  2. Absolutely fantastic! Home Run! The only issue I had was mine was a little grainy and thick. Do you think it is because my blender isn’t powerful enough? I used a Ninja.

  3. This sauce is really good! I have wasted a lot of cashews trying to find a good cashew sauce/cheese recipe. This one is very good and satisfying! It actually has a cheesy taste. It was easy to whip up. I like that it makes 6 servings. I used one serving (1/3 cup) sauce with 1 cup cooked buckwheat pasta. 1/3 cup was plenty for a serving!

    I would highly recommend.

    1. I’m so glad you enjoyed this one, Clara! Thanks for taking the time to leave a review. I really appreciate it. ❤️

  4. I made this tonight for dinner and oh my! It was so deelish!! This surprisingly tastes like “real” alfredo and I didn’t miss the cheese or cream. This is a great recipe and I’ll definitely be making it again.

  5. I haven’t tried this recipe yet but it sounds delicious. Can you tell me why I can no longer dave recipes to your site. there is no save button anymore.

    1. Hi Elizabeth! The website is actually getting a makeover tomorrow (April 29th) and then the save button will be back!

  6. I am in love with this recipe!

    I make a double batch…it’s makes a full meal for 2 people with at least more meals with the left over sauce. I have celiacs disease, this recipe also leaves my tummy happy with no gas or digestion issues. Trader Joe’s now has gluten free fettuccine noodles. It’s a perfect pair! The sauce literally tastes better and better with each meal.
