Cauliflower alfredo sauce
This cauliflower alfredo sauce is EVERYTHING! Seriously, it's a game-changer. Even though we're all on the get-healthy-in-January train right now (all aboard!), this cauliflower alfredo sauce is going to see us through the whole year.
When we ditch the kale smoothies and salads in favor of chocolate cake and peanut butter cookies, this vegan cauliflower alfredo sauce will remain stay strong.
Regular alfredo sauce, with all its cream, butter, and cheese, is pretty darn awesome. For our mouths. Not so much for our bellies. Jeans are feeling a little tighter just thinking about it!
This alfredo sauce is something different. It's made from the highly skilled impersonator, cauliflower. It's cooked with some onions and garlic then blended into a smooth, creamy sauce with some veggie stock.
We've flavored it with a little nutritional yeast … that weirdly awesome flaky stuff that tastes a little like parmesan cheese.
This sauce has been a lifesaver. Whip up a batch in all of 15 minutes then slather it on everything from spaghetti squash to pumpkin alfredo noodles to casserole. It's a total timesaver/ healthy hack.
How to make vegan alfredo sauce

What does cauliflower alfredo sauce taste like?
Since we're eat-everything-arians, we're pretty picky when it comes to imitations of ‘real' food. That's why this sauce is such a dream; it's the best knockoff alfredo sauce ever.
Does it taste EXACTLY like cream and butter loaded alfredo? No, but it's unbelievably close.
It's super creamy even though there's not a drop of cream in sight. And the flavor is mild with a touch of garlic and a little cheesiness thanks to some nutritional yeast.
What to serve with cauliflower alfredo sauce
Pasta is the obvious choice here. Linguini, fettuccini, or even penne or fusilli all go well with this sauce.
And you can add extras like spinach, steamed broccoli, peppers, peas or any other veggie that you like.
This is also a great ‘base recipe”. You can use it to build a special (and healthy!) dinner. Here are a few ideas:
- Add some roasted garlic.
- Pour it over steamed or roasted broccoli.
- Make some vegan mac and cheese pasta.
- Use it as a dip for nachos.
- Pizza sauce!
How long does cauliflower alfredo last?
Cauliflower alfredo sauce will keep well for at least 5 days in your fridge.
Does this recipe freeze well?
Yes! This vegan cauliflower alfredo sauce can be frozen for up to 3 months.
Troubleshooting cauliflower alfredo sauce
This can happen if too much stock evaporates while cooking the cauliflower. If needed, add a little extra stock or water to the blender.
This can happen if your blender isn't very strong. In this case, pour the sauce through a fine-mesh sieve to remove any pieces that didn't blend properly.
When making the sauce, start with 1 teaspoon of salt and 1 tablespoon of nutritional yeast, then add more as needed

Unfortunately, it is really bland and was not a pleasant experience. It would be nice cauliflower soup individually but not over pasta. I’m really lucky I didn’t mix all sauce with pasta, so can eat it sepreatly as a soup.
Seriously so good, exceeded all expectations. It is now my husband’s favorite dinner! That you for a wonderful recipe!
