Easy Keto Cauliflower Mac And Cheese

Keto Cauliflower Mac and Cheese

This recipe for keto cauliflower mac and cheese is the perfect substitute for traditional macaroni and cheese. No need to miss pasta while doing a keto diet when you have a delicious low carb macaroni and cheese recipe like this.

If you’ve been missing your high carb pasta on a keto diet, have I got a tasty and healthy solution for you! This healthy easy keto cauliflower broccoli mac and cheese casserole can stand alone as a main dish, or be served along-side your favorite protein.

It’s a rich and creamy gluten-free macaroni and cheese alternative. Although cauliflower does not behave exactly like pasta. However, its bland flavor absorbs all the flavor of this rich sauce.  And as long as you don’t overcook it, the texture also works. 

The mac and cheese sauce is made using a combination of cream cheese, heavy cream, sharp cheddar cheese and little parmesan cheese for good measure. It’s a similar sauce I used to make for my family when I made macaroni and cheese from scratch for my family.

Except this creamy cheddar cheese sauce needs absolutely no flour to thicken it.

But hey I get it, craving pasta until eating a low carb keto diet becomes a lifestyle, can prove to be tricky. Which is why using vegetables as a pasta alternative makes so much sense.

Low Carb Cauliflower Broccoli Macaroni and Cheese

Keto Mac And Cheese

Back when I was indoctrinated to think that eating low-fat was the only way to stay slim and healthy, I ate loads of pasta.  Sadly, I was only making my gluten sensitivity worse and frankly ate way too little protein to be properly nourished.

In fact, my iron levels were always extremely low and I even required regular iron infusions in order to raise them. Ugh, I was so clueless at the time.

It still never ceases to amaze me how God created our bodies with the ability to heal itself once you give it what it needs. My hemoglobin levels have been fabulous ever since I went low carb. And I have not needed any iron supplement in years.

Randy and I haven’t touched any form of pasta in several years, and frankly, we don’t miss it. I know that sounds unimaginable for some of you. But I assure you if we can do it so can you.

How could we miss pasta though with recipes like this low carb, keto cauliflower broccoli macaroni, and cheese?

Well, I hope it encourages you to know that this is coming from a girl who used to eat pasta several times a week, prior to turning to a low carb keto diet for better health and wellness.

Thankfully, using vegetables as a pasta alternative makes so much sense.

After-all what most people are missing isn’t the bland pasta but what accompanies it.
