Make this keto cauliflower mac and cheese as a side dish for dinner, part of your meal prep, or eat it as a healthy low-carb lunch! It tastes just like your favorite comfort food but is naturally gluten-free and grain-free.
Everybody needs that one recipe that they make when they are craving comfort food from their childhood. Mac and cheese is a really common one!
There is something so satisfying about noodles drenched in a cheesy sauce.
Thankfully, you can still enjoy that creamy and rich cheese sauce – you just need to replace the noodles! I know that cauliflower florets don’t taste or feel like noodles.
When you cover them in this robust sauce, you’ll forget all about pasta. Macaroni? Nope, I’ll take the vitamin-fortified cauliflower.
Ingredients Needed For Cauliflower Mac And Cheese
This recipe only has 5 easy ingredients. In fact, you probably already have these ingredients in your refrigerator and pantry!
I chopped up a fresh head of cauliflower into small florets. This is a messy experience and takes a bit of time, but it is worth it. Fresh cauliflower has a much better texture than frozen.
The cheese sauce is made with butter, heavy whipping cream, and shredded cheddar cheese.
I flavored it with ground mustard. I bet it would taste delicious with some garlic powder in it too. Taste the sauce and add your favorite seasonings to it.
Please note: Check out the recipe card at the bottom for a full list of ingredients used to make this low carb recipe.
- If you want your sauce to be thicker, add more cheddar cheese.
- On the flip side, if you want to thin the sauce down a bit, add a little more heavy whipping cream.
- You can also save yourself time and buy pre-chopped florets in the produce section at your grocery store.
- This is a perfect thing to store in the refrigerator for meal prep! Just be aware that the cream and cheese will harden when you chill it. It will all melt and soften when you heat it up again.
- Store leftovers in the refrigerator in an airtight container for up to a week.
- I used cheddar cheese, but you can also use pepper jack cheese if you want the recipe to be a little spicier.
How To Make Keto Cauliflower Mac And Cheese
All the details and exact steps are in the printable recipe card at the bottom of this post. First, here is a short overview with some photos so you know what to expect.
While the oven is preheating, steam your cauliflower for about 10 minutes.
The cheese sauce is really easy to make! Just melt the butter in a saucepan and then whisk in the heavy whipping cream and your spices.
Add almost all of your shredded cheese and whisk it until it melts. Save some cheese for the end to sprinkle on top before you place it in the oven.
After the sauce is thick and the cheese is melted, put the cauliflower in a casserole dish (you can also use a cast-iron skillet). Pour the cheese sauce on top and sprinkle it with the rest of the shredded cheese.
Bake for about 25 minutes and serve it hot!
What To Serve With Cheesy Cauliflower
This is a high-protein, high-fiber meal all on its own. If you want to eat it as part of a light lunch, add a chopped salad along with it.
You could add some shredded chicken or pulled pork to the dish and have a complete skillet dinner too.
Since this recipe is basically cheesy vegetables, all you really need to add is some more protein for it to be a complete meal.
Frequently Asked Questions About Low-Cab Mac And Cheese

Can you make keto cauliflower mac and cheese spicy?

Why is my cauliflower mac and cheese watery?
There are a few things that will make your cauliflower mac and cheese have a watery/runny sauce.
If you steam frozen cauliflower, don’t add the sauce to the veggies straight out of the bag. Let them cool off on a plate and pat them dry first.
This is also true of you boil the fresh cauliflower instead of steaming them.
Boiling or steaming them in the microwave will make the cauliflower retain water and this water will make your sauce thinner.

- Boiling or steaming the florets in the microwave will make the cauliflower retain water and this water will make your sauce thinner.
