How to make cauliflower alfredo sauce
Step 1: cut up your cauliflower into florets and place in a strainer along with the whole garlic cloves.
Place the strainer over a pot with 2 inches of water and cover with a lid. Steam the florets until fork tender.
Read more on my post on How to Steam Cauliflower for this easy method that I use instead of an actual steamer.
Step 2: once the cauliflower and garlic are finished steaming, add the milk, cauliflower, and garlic to a blender or food processor.
Blend the mixture until smooth.
I suggest using a high powered blender like a vitamix or blendtec for best results. This will result in velvety smooth texture with no lumps or gritty taste. A strong food processor will work well too.
Step 3: Transfer the sauce from the blender to a large skillet or pot.
Step 4: Heat the cauliflower sauce to medium high and the cornstarch. This will thicken the sauce up.
Step 5: Whisk the cornstarch into the cauliflower mixture until the sauce thickens (around 5 minutes).
Step 6: Stir in your freshly grated parmesan cheese, then 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!
This sauce is incredible served over fettuccini with a side of fresh broccoli.
This is one of the most incredible things I have ever tasted.
I want to just drink this cauliflower sauce from a bowl and just call it soup!
It is so very insanely creamy and decadent. Even my kids gobble it up!
This cauliflower Alfredo sauce is sure to be a hit with your family!
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’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!

I roasted my cauliflower and garlic with a drizzle of olive oil wrapped in aluminum foil instead of steaming, and the resulting sauce is amazing! Will definitely use this often!

I would not recommend frozen cauliflower for this recipe as it would have more water content.

I use this recipe all kinds of ways. Like to use l/2&l/2 instead of 2% milk and add half a packet of dry ranch dressing mix

What’s the serving size?? 1 cup? 1/2 cup?? Counting macros so it would be helpful to know. I usually just cook for myself.
