In the making of this cauliflower spotlight, I’ve served some form of cauliflower for dinner every night for the past two weeks. But the thing about cauliflower being the chameleon of the kitchen is…you just don’t get tired of it!

We disguised it as General Tso’s “Chicken” and Thanksgiving “Turkey” and Pizza Crust. And now…we macaroni.

This naturally gluten-free and keto friendly cauliflower mac and cheese has just 5 ingredients and is ready in 15 minutes! Perfect for healthy holiday feasting or weeknight cooking.

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!

How to make this cauliflower mac and cheese

To keep it quick and weeknight-ready, we’re making this mac and cheese on the stovetop! There are basically just two steps:

  1. Cook the cauliflower in boiling water until tender (5 minutes).
  2. Stir everything together.

It’s that easy. No messing around with a roux. No waiting for your oven to preheat. No dirtying up loads of pots and pans. This is the easy one-pot cauliflower mac and cheese that dreams are made of.

Ingredients

  • 1 head cauliflower
  • 1 tsp salt

  • 4 oz cream cheese 113 g
  • 1 tsp dijon mustard 5 g
  • Salt and pepper to taste

Instructions 

  • Cook: Roughly chop cauliflower into marble-sized pieces. Bring a large pot of water to a boil, then add cauliflower and salt. Cover and let simmer for about 5 minutes, or until cauliflower is fork-tender.

For a melty browned top, transfer cooked cauliflower macaroni and cheese to a baking dish. Sprinkle with a bit more cheddar and broil in the oven for just a few minutes, until cheese has melted and is golden brown.

    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!5 stars

    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.5 stars

    Can you use whipped cream cheese or does it need to be the block style?
