Ingredients for Cauliflower Mac and Cheese
- Cauliflower: Cauliflower makes up the base of this macaroni and cheese. Looking to save even more time? Buy it pre-chopped!
- Cheddar Cheese: Shredded sharp cheddar cheese brings the distinct cheesy taste to this low carb and cheese. Feel free to sub half of the cheddar for mozzarella or pepper jack!
- Cream Cheese: While most macaroni recipes rely on a flour roux to add creamy thickness, we’ll simply use cream cheese.
- Mustard: Our secret ingredient that brings everything together! It brings a pop of zing that makes this dish feel less heavy.
- Salt and Pepper: Season to taste, adding your favorite spices like cayenne or smoked paprika!

It is amazing! If you love garlic you can add a tsp of garlic powder and a slice of butter too. A pretty tasty and very delightful dish in the end. Thank you!

YUM! Can never have too much garlic!

Yep absolutely! Stays good for about 5 days in the fridge.

Easy and amazing – much healthier alternative to pasta. The true test was that my 17 year old son who complains about most of what I make and lives by the boxed mac n cheese gave this 4.5 stars. Definitely will eat again.

Can you freeze this
Sarah Bond says
I haven’t tried freezing this so I can’t be sure, but I think it would work! š
Frances says
Can you use whipped cream cheese or does it need to be the block style?
Sarah Bond says
I think that would work well! š
