What’s in this cauliflower mac n cheese?

The base of this recipe uses roasted cauliflower instead of macaroni pasta, making it a great low-carb choice for keto. Coated in a cheesy, creamy sauce composed of cheddar cheese, cream, milk and seasonings it makes an extremely comforting, rich recipe that pairs perfectly with your favorite protein source.

How to make it?

Roast the cauliflower until golden and crisp, before preparing the decadent cheese sauce in a saucepan over low heat. Pour the cheese sauce over the cauliflower and gently combine. Pair with your favorite simple protein source and serve immediately.

Suggested substitutions

You are welcome to use any milk of your choice for this recipe, based on preference or any dietary restrictions. This sauce works pretty nicely with plant milks such as almond milk or soy milk also. I do find that cow’s milk works best, and it’s fine with any of hi-lo, skim, or lactose-free milk (I find lactose-free to be the best balance of tasty and keto-friendly).

Also, If you prefer a stretchy, cheesy sauce, you can easily substitute the cheddar cheese for mozzarella.

How long will it keep in the fridge?

This recipe will last up to 4 days in the fridge. To prevent the cauliflower from becoming soggy, it is best to keep the roasted cauliflower and sauce separate until ready to serve. Once combined, simply reheat in the microwave.
