Why This Classic Works
I used to think dairy-free sauces needed a lot of salt to mimic the savory depth of traditional cheese. I was completely wrong about that.
Nutritional yeast combined with fresh lemon juice provides all the tangy flavor you actually need. Blending soaked cashews creates a surprisingly authentic creamy texture that clings to pasta perfectly.
Low Sodium Vegan Alfredo Sauce Recipe Ingredients
- 1 cup raw cashews (soaked in hot water for 30 minutes)
- 1 cup low-sodium vegetable broth (or water)
- 2 tablespoons nutritional yeast
- 1 tablespoon fresh lemon juice
- 2 cloves fresh garlic, minced
- 1/2 teaspoon onion powder
- 1/4 teaspoon ground black pepper

How To Make Low Sodium Vegan Alfredo Sauce Recipe
- Soak the cashews: Place the raw cashews in a bowl of boiling water and let them sit for 30 minutes until softened, then drain well.
- Blend the base: Add the soaked cashews, low-sodium broth, nutritional yeast, lemon juice, garlic, onion powder, and black pepper to a high-speed blender.
- Purée until smooth: Blend on high for 2 minutes until the mixture is completely smooth and creamy, scraping down the sides as needed.
- Heat and thicken: Pour the sauce into a skillet over medium-low heat and gently warm it for 3 to 4 minutes until slightly thickened.

Recipe Tips
- Use raw cashews: Roasted cashews will change the flavor profile and will not blend into the pure white, creamy texture you want.
- Adjust the consistency: If the sauce becomes too thick in the pan, simply whisk in a splash of warm water or extra low-sodium broth.
- Blend thoroughly: Do not rush the blending process, as getting a completely grit-free texture is essential for a good sauce.
What To Serve With Low Sodium Vegan Alfredo
Pour this creamy sauce over freshly boiled fettuccine or zucchini noodles for a comforting dinner. It also tastes fantastic draped over steamed broccoli, green peas, and roasted cauliflower.

How To Store
Store any leftover sauce in an airtight glass jar in the refrigerator for up to 4 days. When reheating on the stove, add a splash of water to loosen the texture as it will thicken significantly in the fridge.
FAQs
Can I freeze vegan Alfredo sauce?
Yes, you can freeze it in a sealed container for up to 3 months. Thaw it overnight in the fridge and whisk well over low heat to restore the creamy texture.
Do I have to soak the cashews?
If you have a very powerful high-speed blender, you can skip soaking, but soaking always ensures the absolute silkiest texture.
What can I use instead of cashews?
Blended silken tofu or soaked raw sunflower seeds can work as a nut-free alternative, though the texture and richness will be slightly different.
