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).

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.

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

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.

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

You could, but unfortunately I do not know what quantity you would need.
