This cauliflower alfredo sauce has fast become one of my favorite sauces to make.

It is velvety smooth, rich and cheesy, and secretly full of veggies.

Now that’s a winning combination in my book!

How to make cauliflower alfredo sauce

First, cut up your cauliflower into florets and steam with the whole garlic cloves until fork tender.

Read my post on How to Steam Cauliflower for the easy method that I use instead of an actual steamer.

Once the cauliflower is steamed, add milk, cauliflower, and garlic to a blender or food processor and blend until smooth.

I suggest using a high powered blender like a vitamix or blendtec for best results. This will result in velveety smooth texture with no lumps or gritty taste.

Transfer the sauce from the blender to a large skillet or pot.

Heat sauce to medium high and cornstarch. 

Whisk until sauce thickened (around 5 minutes).

Stir in your freshly grated parmesan, salt, and pepper to taste.

Continue stirring until the cauliflower alfredo sauce is thick and creamy.

Serve over pasta of choice!

We love shells, fettuccini, or elbow noodles. Any pasta would work!

I do not lie to you when I say this is one of the most incredible things I have ever tasted.

I basically want to just drink this cauliflower sauce from a bowl and just call it soup!

It is so very insanely creamy and decadent.

Every recipe that I share on my blog is one that I have personally tried, tested, and enjoyed.

This cauliflower alfredo sauce is sure to be a hit with your family!

The sauce is so insanely flavorful that I was licking the spoon…I lost count of how many times.

This recipe gave me another reason to love my blendtec.

It’s perfect for getting that perfectly smooth texture of the sauce.

You can use a food processor, but be warned that it might not be able to get the sauce perfectly smooth.

I have made it both ways and prefer the texture from using my blender.

There is no grit and no chunks, just super smooth and delicious cauliflower sauce!

We served it over shell pasta. Any pasta you have on hand will work!

You can also serve it over fettuccine for easy fettuccine alfredo.

I have always been a cauliflower lover, but this recipe turned me into addict status.

Between this recipe and my roasted cauliflower shells and cheese, I could eat it all week long!

I made this cauliflower alfredo sauce to use as a base in my Cauliflower Alfredo Pasta Bake and it’s basically LIFE CHANGING.

I could eat this sauce as a soup. By itself. Every single day.

Seriously such an easy to make sauce with tons of hidden veggies (try this one on your kids!)

I sound like a broken record here, but I just can’t get enough.

I’m even thinking of putting it on pizza for the sauce!

This sauce is super thick and makes a large batch, so there is plenty to go around!

Can we store this sauce? If yes, then for how long?

You could store leftovers in the fridge, just use within 3 days I would think.

I know I’m late to this party, but this recipe was amazing! Used almond milk and a little avocado butter and it was delicious!

This looks delicious! But I can't have liquid dairy...do you think I could sub almond milk for the 2% milk?
