The Best Vegan Alfredo Sauce Recipe (With Fettuccine) - Elavegan (1)Creamy, dreamy pasta! Yes, this sums it up pretty nicely. Today I am presenting you with the best dairy-free Alfredo sauce recipe that I’ve ever made! The recipe is vegan, gluten-free, healthy, high protein, and super creamy. Plus, you can make it in less than 30 minutes!

This healthy Alfredo sauce is also perfect as a meal-prep option for a wholesome, delicious lunch, or dinner. It can be served with pasta (I used Fettuccine to make a Fettuccine Alfredo), however, you could also serve this sauce with spiralized zucchini or carrot instead, for a low-carb/keto version.

What is Alfredo Sauce?

Traditionally, Alfredo sauce (i.e. Fettuccine Alfredo) is a dairy-filled Italian pasta dish. The main ingredients include butter and cheese, which then became butter, cream, and cheese when it was popularized in America and other parts of the world. The result is a rich, decadent (but fairly unhealthy) sauce.

This dairy-free Alfredo sauce recipe, however, contains all the creaminess and luxury of the original and is packed with flavor, but without any dairy. In fact, with a clever selection of ingredients including cauliflower and hemp seeds, this homemade Alfredo sauce is healthier and far more nutritious – it’s really a win-win situation.

I love creating healthy recipes that are packed with nutrients and tons of healthy veggies. Whether it’s in plain sight or hidden like in this delicious hidden veg Healthy Vegan Mac And Cheese, there’s rarely a day when I’m not getting my five-a-day!

I even love including them within my baked goods- often incorporating veggies like zucchini and sweet potato into my cakes. For example, this Chocolate Zucchini Cake or even these Vegan Brownies With Peas (yes peas! Don’t knock it till you’ve tried it).

After my Vegan Pasta Bake with cauliflower turned out so creamy and delicious, I decided to experiment with making a creamy cauliflower Alfredo sauce (spoiler alert- it was a success!). What resulted is the best vegan Alfredo sauce I have ever had, and all with a simple ingredients list of healthy plant-based ingredients.

While cauliflower may be the veggie star of the show for this healthy Alfredo sauce, hemp seeds play a massive part in providing rich flavor and plenty of healthy nutrients. With a nutty flavor and soft texture, these little seeds blend perfectly into a creamy nut-free Alfredo sauce.

The Best Vegan Alfredo Sauce Recipe (With Fettuccine) - Elavegan (4)Hemp Seeds

You probably know that it’s important for vegans to eat healthy omega-3 fatty acids. These essential fats can’t be made from scratch, and so have to be consumed in our diet – usually linked with oily fish, but also available in several plant-based sources. These include leafy vegetables, flax seeds, and, of course, hemp seeds.

Omega-3 fats are key to the function of our cell membranes, with studies showing that they may reduce inflammation and regulate blood clotting. They could even reduce the risk of heart disease, dementia, and stroke. Plus, studies also show that Omega-3 may help control rheumatoid arthritis, lupus, and eczema.

Nuts often feature heavily in the vegan diet and contain protein as well as lots of Omega-6 fatty acids (walnuts being the exception – as a rich source of Omega-3). However, it’s important to keep a healthy balance between omega-3 and omega-6 fatty acids!

Hemp seeds are loaded with omega-3 fatty acids, omega-6 fatty acids, and omega-9 fatty acids. Hemp is also rich in zinc, magnesium, iron, fiber, and amino acids. Do you know that it actually contains all 20 amino acids, including all 9 essential amino acids? Overall, hemp is a unique source of support for muscles, heart, and digestive health and helps to make this vegan Alfredo sauce incredibly nutritious and a high-protein meal option.

I already love to sprinkle hemp seeds over a variety of meals like soups, salads, and Buddha bowls or even include in smoothies and sauces. For this healthy Alfredo sauce, they take the dish from a simple cauliflower sauce to rich and creamy. I love using Sunfood’s Hemp Seeds since they are organic, raw, and have a superior quality!

Making this homemade Alfredo sauce only includes a few steps. I’ve then combined the flavorsome sauce with Fettuccine pasta, sautéed mushrooms, and topped with parsley, for a comforting, wholesome meal. For the full list of ingredients, measurements, and nutritional information (calories, etc.) please check the printable recipe card below. Check the video for visual instructions!

STEP 1: Begin by preparing the cauliflower and pasta. Chop the cauliflower into florets and cook in lightly salted water for 10-15 minutes, or until fork-tender. Then, drain the water.

STEP 2: In another pot, cook the pasta of your choice according to the packet instructions. If using spiralized vegetables, these can be eaten raw or lightly sautéed for a few minutes, before serving.

STEP 3: As both ingredients are cooking, lightly sauté the garlic in a pan for a few minutes, until browned and then add this along with the cauliflower and all other ingredients (apart from the pasta, mushrooms and fresh herbs) into a high-speed blender/ food processor and blend until smooth and creamy. This usually takes between 1-2 minutes. You can then taste the sauce and adjust seasonings, according to taste.

STEP 4: Heat another teaspoon of oil in your skillet and sauté the mushrooms for a few minutes, seasoning as necessary, until lightly browned.

STEP 5: Pour the sauce over the cooked pasta (or veggie ‘noodles), add your mushrooms and herbs, and enjoy!

  • How to store: This sauce is very meal-prep friendly and can be stored in an airtight container in the refrigerator for 3-4 days.
  • Can I freeze it? Although I’ve not tried it personally, I would imagine this sauce is also freezer-friendly. Simply leave to thaw overnight then reheat on low, mixing well. You may need a splash of water or plant-based milk to bring it back to the smooth and creamy consistency.
  • Add more greens: Make this Fettuccine Alfredo recipe even healthier with the addition of some greens. This includes broccoli, peas, spinach, or kale.
  • Make it low-carb: For a keto Alfredo sauce or low-carb version, swap the pasta for spiralized or ribbon zucchini or carrot.
    If you don’t have hemp seeds you can omit them and use soaked cashews nuts instead. You can also swap the hemp seeds for two tablespoons (about 40 grams) of sunflower seed butter.

Flavor Boosters

Nutmeg: A pinch of freshly grated nutmeg can elevate the flavors in your Alfredo sauce. However, use it sparingly; a little goes a long way.

What is the secret to thick Alfredo sauce? ›


The easiest way to accomplish this is to mix about a spoonful of cornstarch to 2 spoonfuls of liquid – it could be water or chicken stock or even milk. You will add this mixture, also called a slurry to the sauce and as it starts to cook, the sauce will thicken.

What is a substitute for heavy cream in fettuccine alfredo? ›

Instead of the typical heavy cream laden alfredo sauce recipes you are likely to find, I just use regular milk in mine and I do not miss the cream one bit. It's still very creamy and rich tasting, but I like knowing I saved a few grams of fat.

Yes, pasta can be eaten if you're vegan. Most pasta is made from wheat flour and water, both of which are vegan. However, some pasta may contain eggs or milk, so it's important to check the label before you buy it. You can also find vegan pasta made with alternative flours, such as chickpea flour or lentil flour.

To make a cornstarch slurry, whisk together equal parts of cornstarch and water—about 2 tablespoons of each. From there, add 1 to 2 teaspoons at a time. Start by whisking just 2 teaspoons of the slurry into the sauce, let it come to a boil, which will activate the starch, and then add more if needed.

Extra seasonings and spices will go a long way in adding flavor to a boring jar of sauce.

Start with small amounts (1/2 teaspoon at a time) and add as needed, in order to avoid over-spicing.

Should I add pasta water to Alfredo sauce? ›

After 12 ounces of fettuccine pasta noodles are finished cooking, reserve 2 cups of the pasta water to include in your sauce. The starchy water is essential to creating a thick, creamy sauce consistency.

The Fix Is Simple—Add Water Back.
