Easy Keto Cauliflower Broccoli 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 alongside 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.

Just because you’re doing a keto diet doesn’t mean you have to live without comfort food. 

With just a few key swaps you can enjoy this indulgent keto mac ‘n’ cheese.

I decided to add broccoli to my easy keto cauliflower mac and cheese for added nutrition and flavor.  You can, however, substitute the broccoli for cauliflower if you so desire. 

Of course, in order to get this keto mac n cheese to taste like its wheat counterpart, I placed it under the broiler for a few minutes giving this casserole a crunchy cheesy topping.

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

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

And like any homemade mac and cheese, the secret is in the cheese sauce. You’ll be happy to know that this cheesy sauce delivers a big flavor. 

In fact, I serve this broccoli mac and cheese (keto) to my non-keto family members, and guess what? They TOTALLY love it. But what’s not to love? It’s made with a decadently rich sauce!

What I love about using vegetables to take the place of pasta is that if cooked correctly, you can get the perfect mouth-feel that traditional pasta has without the massive amounts of carbs and loads more nutrition.

I assure you that you won’t miss your regular mac and cheese with this easy keto cauliflower broccoli macaroni and cheese casserole and neither will your non-keto friends and family.

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 themselves once you give them 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.
