💭 What is cauliflower alfredo?
Traditionally, alfredo is a pasta dish made with fettucine pasta, where butter, cream and Parmesan cheese are used to make a white sauce.
This vegan version still has a creamy comfort food white sauce, but uses cauliflower as the base instead. Instead of butter and cream, we use coconut cream to keep the recipe vegan. All the flavour comes from the cauliflower, herbs and garlic, and its delicious!
⭐ Why you'll love this recipe
- Comfort food vibes - this cauliflower pasta sauce feels so cosy and warming, and perfect for the colder months.
- Tomato-free sauce - many pasta sauces are based on tomatoes, so this is a good alternative!
- Quick and easy - this evening meal comes together in around half an hour with just a few simple steps.
🍝 Ingredients
This vegan cauliflower alfredo sauce is made without cream, and uses coconut cream in its place. It gives the same creamy taste and texture, but keeps the recipe vegan.
Just a few ingredients to make this pasta. You will need:
- Cauliflower - the main ingredient of the sauce. Choose one that looks fresh without brown markings.
- Pasta - while alfredo traditionally uses fettucine, I use spaghetti for this dish. Any pasta would work well though!
- Olive oil, onion and garlic - for the base of the sauce and to give flavour. If you like more garlic add another clove (or two!).
- Thyme - a pinch of dried thyme works so well with the cauliflower.
- Parsley - to garnish.
- Salt and (optional) pepper - to season.
🔪 Step by step instructions
Just a few steps to make this vegan cauliflower alfredo, and all are easy to do:
Step 1
On a low to medium heat fry onion and garlic in olive oil, taking care not to burn the garlic. Cook until softened. Add the cauliflower florets, thyme and water. Bring to a boil and then reduce the heat to a very light simmer. Spoon in the coconut cream.
Step 2
While the cauliflower is cooking, cook the pasta according to packet instructions.
Step 3
Blend the cauliflower mixture until smooth and creamy. Return to the pot. Drain the pasta and add to the cauliflower sauce. Stir to coat the pasta, and then use tongs to transfer to your serving plate. Sprinkle with salt, pepper (if using) and fresh parsley.
💭 Recipe tips and notes
- Choose a fresh cauliflower without any obvious markings. Fresh produce is always best!
- Adjust the amount of garlic and thyme to taste preference.
- Blend the sauce quite well so that it becomes creamy and light.
- You can use a food processor to blend, or I use a Nutribullet (less clean up!).
- Stir the sauce through the pasta so that it is well coated.
📋 Frequently asked questions
I love this recipe as is, but if you want to increase the protein a little you can add soaked cashews or pistachios to the recipe.
Fettucine is most often used for alfredo, but spaghetti and linguine work great too!
You can use vegetable stock rather than water to make the cauliflower alfredo sauce for a more savory flavor.

Delicious 😋
I used ghee instead of olive oil, a little extra garlic (because yum garlic) & fresh thyme. Doubled the sauce recipe and froze individual portions. I'm so glad that I did because this sauce tastes so good. Thank you for the recipe!!
Claire says
So glad you like it Marie! I'm quite the garlic fiend too 🙂 Love that you have some in the freezer for other days as well!

This was so great! Not only do I need low histamine but my husband is both gluten and dairy sensitive and loved this. It’ll be a regular dish for sure! Tomorrow I’m trying the spicy Turkey stew!
Claire says
Oh that's lovely to hear! So glad it works for both of you. It can be tricky when different people have different dietary requierments can't it. And hope you like the turkey stew too! Thanks so much for taking the time to comment 🙂

Creamy and a great low histamine comfort food. I added more garlic and thyme, sprinkled some fresh green onion and garnished with fresh parsley. A definite go to recipe in the future.
