This homemade Easy Dairy-Free Alfredo Sauce recipe is vegan, nut-free, & made with only 7 simple ingredients. You’ll never guess the secret healthy ingredient!
I really have no business making an alfredo sauce recipe. I haven’t had a forkful of creamy fettuccine probably since I was 12 years old. That’s a solid decade and a half between us.
So why am I writing about alfredo? I thought you’d never ask.
I’m not too big on creamy. I’ll pass on a broccoli cheddar, take a marinara over any and all sauces, and opt for alternative milks simply because I don’t like the taste of dairy milk. But here I am. Just a girl, standing in front of alfredo, asking it to not be creamy.
What makes this alfredo sauce recipe healthy and delicious:
- non-dairy milk
- lemon juice
- nutritional yeast
How to make this alfredo sauce
In a microwave-safe bowl, add 2 medium white potatoes that have been peeled and cubed with 1/4 cup water. Heat them on high for 8 minutes in the microwave, or until fork tender, being careful when removing bowl from microwave. Drain off water, and add potatoes to a blender.
Add 1/2 cup non-dairy milk, 1 clove of garlic, 1 tablespoon of lemon juice, 1 teaspoon of salt, 1/4 teaspoon of pepper, and 2 tablespoons of nutritional yeast to the blender, and blend on high until smooth. Heat when ready to serve, and use additional non-dairy milk if sauce gets too thick.
- Add directly to pan of pasta when cooking to heat it up at the same time.
- Add additional non-dairy milk (I used almond milk) to sauce if it starts to get too thick.
- For more of cheesy flavor, add 1 teaspoon more of nutritional yeast.
How long does this alfredo sauce last?
If stored in the refrigerator in a sealed container, this sauce should last at least 5 days.
Can you freeze this alfredo sauce?
Since it is made with potatoes, I don’t recommend freezing since this will alter the texture of the sauce when thawed. Luckily it takes almost time to make!
What if I don’t have nutritional yeast?
Unfortunately, that’s what gives this sauce it’s alfredo feel, so leaving it out would alter the flavor. If you have a favorite vegan or dairy-free parmesan cheese, adding that in place of the nutritional yeast would be your best bet.
Money-Saving Tips for this Alfredo Sauce Recipe:
- Buy whole potatoes. Not the pre-mashed stuff. Not only are they cheaper, but you also control what goes in them.
- Use the bulk section. If I can find nutritional yeast in the middle of nowhere California in the bulk section of my grocery store, you can too. Plus, it’s much cheaper than the canister option.
- Buy refrigerated. I find the refrigerated almond milks to be more affordable, and tend to have fewer ingredients than the shelf-stable versions.
