What stands out

You’ll love this simple Vegan Alfredo Sauce because it has all the rich creamy goodness of traditional Alfredo while being healthier and – believe it or not – easier to make. Thanks to blended cashews, this sauce is silky smooth and luscious. Bold garlic adds depth of flavor and warmth to every bite. Keep it simple or layer in your favorite herbs, spices, or a splash of lemon for extra brightness. Our Vegan Alfredo Sauce is a blank canvas with loads of flavor potential!

• Cashews – Soaked raw cashews are blended until smooth to form the velvety base of this sauce. They’re naturally buttery and mild, making them suited to creating that classic Alfredo texture—no dairy needed.
• Garlic – Fresh garlic adds depth of flavor and balances the creaminess of the cashews.
• Salt – This tiny but essential ingredient ties all the flavors together. We use Redmond Real Salt for added healthy minerals.
• Warm liquid – Warm pasta water adds a bit of starch and flavor, and veggie broth gives the sauce a savory boost. Either one works, so choose whatever you have on hand!

Kitchen tip

We have made this version many different ways and sometimes love adding roasted bell peppers or sun-dried tomatoes to make it even more or to switch things up.

How to Make Vegan Alfredo Sauce from Scratch

For our quick-soak method, place raw cashews in boiling-hot water and let them soak for about 30 minutes. This softens them for straightforward blending and a smooth texture. Not to mention, this method saves you about 12 hours of prep time!

Drain the soaked cashews and add them to a high-speed blender with garlic, salt, and your choice of pasta water or vegetable broth. Blend until completely smooth and creamy.

Pour the sauce into a pan and gently heat over medium-low for about 5–10 minutes, stirring occasionally. This helps the flavors come together and slightly thickens the sauce. Toss it with your favorite pasta, drizzle over roasted veggies, or use it as a base for more flavor-packed variations with herbs, spices, or plant-based proteins.
