Vegan alfredo sauce ingredients

  • Raw cashews – Blended cashews turn into a creamy sauce in a pinch! Macadamia nuts are a great substitution if you don’t have cashews, or you can use sunflower seeds or hemp seeds as a nut free alternative (the taste will be slightly different).
  • Lemon juice – The acidity from fresh lemon juice brings balance and brightness to the sauce.
  • White miso paste – For a light umami flavor. If you can’t find miso, you can use gluten-free tamari, coconut aminos, or soy sauce.
  • Seasonings – A mix of nutritional yeast, onion powder, and garlic powder make this sauce taste savory and cheesy.

How to make the sauce

This alfredo sauce couldn’t be easier to make. In just 3 simple steps and using only a blender, you’ll end up with creamy pasta sauce in minutes! Here’s how it’s done:

Step 1: Blend the sauce: Add all of the ingredients to a blender and blend until smooth.

Step 2: Adjust: The sauce may be too thick at this point, so feel free to add a tablespoon of water at a time until it’s thin enough for your liking.

Step 3: Pour and enjoy: Pour the finished vegan alfredo over cooked pasta (like fettuccini), on top of vegetables, or anything else you like!

Serving suggestions

Creamy cashew sauce has a special ability to transform everyday dishes into delectable and comforting meals. These are my favorite ways to serve the vegan alfredo sauce: 

  • With pasta – Pour the sauce over your favorite cooked noodles, gluten free noodles, spaghetti squash, or zoodles.
  • In casseroles – Like lasagna, pasta bakes, vegetable and rice bakes, or vegan scalloped potatoes.
  • With grains – Spoon in some of this sauce into quinoa cooked brown rice to make a creamy dish (like a risotto)
  • Over veggies – Roast your favorite veggies and pour the sauce over top, stir them into mashed potatoes, or use it to make vegan au gratin potatoes.

Tips for customizing

Serving vegan fettucini alfredo for dinner? Customize each bowl with fun add-ins or toppings! Use these tips to make the best bowl of vegan alfredo:

  • Veggie add ins – Like roasted mushrooms, cherry tomatoes, asparagrus, broccoli, peas, garlic, or leafy greens.
  • Vegan protein add ins – Stir grilled tofu steaks, marinated tofu, tempeh crumbles, tofu crumbles, soy curls, or vegan chicken into the fettucini alfredo.
  • Toppings – Top each bowl with vegan parmesan, lemon zest, fresh basil or parsley, a dollop of vegan pesto, hemp hearts, red chili flakes, nutritional yeast, or pine nuts.

Frequently asked questions

Does it really taste like traditional alfredo sauce?

It totally does! When I make this for family and friends, they’re always telling me how much they love it and how it tastes just like alfredo sauce with dairy.

Is this sauce healthy?

Traditional alfredo sauce is made with loads of dairy and garlic to give it a rich and creamy taste. I wanted to create a vegan version that’s just as delicious but with much lighter, healthier ingredients. 

A batch of my vegan alfredo sauce has about 225 calories and is made with a handful of simple plant-based ingredients, like cashews, miso paste, and lemon juice. It also happens to be naturally oil-free, egg-free, dairy-free, and gluten-free. Compared to the classic recipe which can have anywhere from 430-530 calories, I’d say this vegan alternative is much healthier!

How long does it last?

Leftover dairy-free alfredo sauce stays fresh in the fridge for up to 3 days

How can it be reheated?

Heat up the leftovers for 1 or 2 minutes in the microwave (stirring every 30 seconds) or in a pot over medium heat on the stove. You may need to stir in a little extra water to thin it out.

Can I freeze the sauce?

Yes! You can pour the blended sauce into an airtight container and keep it in the freezer for up to 3 months.

I can’t eat cashews, what I can substitute?

If you can’t eat cashews, feel free to substitute the same amount of macadamia nuts. The sauce will still be nice and creamy.
If you’re nut-free, you can try subbing soaked sunflower seeds or raw hemp seeds, though the sauce will have a different flavor.
