I tried were disappointing. They were enough to make me give up altogether—until I created this version. It delivers the rich, silky texture and satisfying comfort you expect from Alfredo, without dairy, oil, or processed ingredients. One taste, and you just might agree this is the best WFPB Italian Alfredo sauce.
Why This Alfredo Sauce Works
The magic of this sauce lies in its simple, whole‑food ingredients. Cauliflower and raw cashews are blended until completely smooth, creating a luxuriously creamy base that mimics traditional cream‑based Alfredo.
As the sauce rests, the cashews naturally thicken it, giving it body and cling—perfect for coating pasta. It is even a great white pizza sauce! If needed, you can easily adjust the consistency. Add a bit of reserved pasta cooking water until it’s just right.
Texture, Consistency, and Serving Tips
This Alfredo pairs beautifully with fettuccine, linguine, or even rotini for extra sauce capture.
- Blend thoroughly for a completely smooth, restaurant‑quality sauce.
- Allow the sauce to stand for a few minutes so it can naturally thicken.
- Always reserve some pasta cooking water to loosen the sauce if needed.
- Serve immediately in warmed bowls for optimal creaminess.
The Italian Roots of Alfredo Sauce
Have you ever wondered how this rich, creamy sauce became synonymous with Italian pasta—or why it’s called “Alfredo”? The modern version of Alfredo sauce traces back to early‑1900s Rome. In this period, restaurateur Alfredo Di Lelio created a simple dish of pasta tossed with butter and cheese.
Legend has it he developed the recipe to help his wife regain her appetite after childbirth. The dish became so popular. It earned a permanent place on the menu at his family restaurant, Alfredo alla Scrofa. In the 1920s, Hollywood stars Douglas Fairbanks and Mary Pickford visited Rome on their honeymoon. They tasted Alfredo’s famous pasta and fell in love with its simplicity. They also admired its richness. When they returned to Hollywood, they couldn’t stop talking about it, and soon Alfredo sauce swept across the United States.
Alfredo alla Scrofa became a must‑visit destination for international movie stars and directors. Legends like Sophia Loren, Frank Sinatra, and Brigitte Bardot dined there to experience the dish everyone was raving about.

Add-Ins and Substitutions
The only substitute one should make in this recipe is the plant-based milk.
I have successfully reduced the amount of cashews by a third. However, it might result in a thinner sauce. The sauce will thicken upon sitting for a bit.
Storing
Store leftovers in airtight containers. Reheat leftovers with additional plant-based milk to thin the sauce. Adjust seasonings accordingly.
Nutrition 411
Cauliflower is high in fiber and water. Both are important for preventing constipation, maintaining a healthy digestive tract, and lowering the risk of colon cancer. Studies have shown that dietary fiber may also help regulate the immune system and inflammation. As a result, it could help decrease the risk of inflammation-related conditions such as cardiovascular disease, diabetes, cancer, and obesity. A high fiber intake has been associated with a significantly lower risk of developing: coronary heart disease, stroke, hypertension, diabetes, obesity, and certain gastrointestinal diseases. A higher fiber intake appears to help lower blood pressure and cholesterol levels, improve insulin sensitivity, and enhance weight loss for people with obesity. Cauliflower contains antioxidants that help prevent cellular mutations and reduce oxidative stress from free radicals. (trusted source).
Cashews are commonly referred to as tree nuts, and nutritionally comparable to them, cashews are really seeds. They’re rich in nutrients and beneficial plant compounds and make for an easy addition to many dishes. Cashews are rich in carotenoids and polyphenols, two categories of antioxidants that may help reduce inflammation and offer protection from disease. Like most nuts, cashews may also help improve your overall health. They’ve been linked to benefits like weight loss, improved blood sugar control, and a healthier heart. (trusted source).
Best WFPB Alfredo Sauce
Equipment
- Dutch Oven
- High speed Blender
- Stock Pot
Ingredients
- 3 cups unsweetened almond milk plus more to thin out thickened sauce
- 2 tbsp white miso
- 10 ounces cauliflower florets cut into ½-inch pieces
- ¾ cup raw cashews chopped
- 3 tbsp nutritional yeast
- 1 tsp ground mustard
- ½ tsp salt and pepper to taste
- Pinch ground nutmeg
- 1 pound shells or other pasta like fettuccine
- 2 tbsps chopped fresh parsley for garnish
Instructions
- Combine almond milk, miso, ground mustard, nutmeg, pepper, and salt in large saucepan and bring to simmer over medium-high heat, whisking to dissolve miso and nutritional yeast.
- Stir in cauliflower and cashews, reduce heat to medium-low, and cook, partially covered, until cauliflower is very soft and falls apart easily when poked with fork, about 20-25 minutes.
- Process cauliflower mixture and 1/2 cup water in the high powered blender until very smooth, about 3-5 minutes total, stopping to scrape down sides and add a bit more almond milk as needed.
- Meanwhile, bring 4 quarts of water to boil in a large pot. Add pasta and 1 tablespoon salt and cook, stirring often, until nearly tender. Reserve ½ cup cooking water, then drain pasta and set aside.
- Transfer the pureed cauliflower mixture to the now-empty pot. Bring to a gentle simmer over medium-low heat. Add drained pasta and cook, stirring constantly, until warmed through and the sauce is slightly thickened, about 3 minutes. Adjust consistency with reserved cooking water and almond milk as needed. Season with salt and pepper to taste, sprinkle with parsley and serve immediately.
Notes
- I have made this recipe using 1/2 cup cashews with success. The longer it sits the ticker it becomes
- Here are a few ways to warm bowls and plates for serving:
- Put them in the oven at its lowest setting (200° F) for 5 minutes.
- Run them under really hot water for 10 seconds then quickly towel dry them just before plating.
- Use an electric plate warmer: think of it as a plug-in tower of hot pillows for your plates.
- Use the Dishwasher by putting the clean plates on the drying cycle to warm them up.
