This cauliflower mac and cheese is made with tender cauliflower florets and a creamy cheese sauce in just 15 minutes on the stove. It’s low carb, keto-friendly, and tastes just like real mac and cheese.


The cheese totally makes up for the lack of carbs.
Trying to cut carbs? One of the toughest parts can be feeding a family at the same time. You definitely don’t want to cook two meals, so I like to figure out recipes that fit those health goals and keep the kids happy.
Enter this keto cauliflower mac and cheese. There is no actual mac in the recipe – just cauliflower that’s been chopped into macaroni sized pieces, boiled until tender, and then coated in a super rich and creamy sauce. All in one pot. All done on the stove. Ready in about 20 minutes.
The cauliflower does a good job in terms of texture and it has a neutral flavor while mostly serving as a delivery vehicle for all that cheesy goodness. It’s more nutritious than macaroni and it does the job of keeping the whole family happy!
The low carb cheese sauce skips the traditional roux. Instead, you’ll just heat some heavy cream and stir in your grated cheese until everything is smooth and creamy. Same approach as you’d take for homemade alfredo sauce!
♥ 3 Reasons You’ll Love This Recipe:
Quick & Easy: This dish comes together in about 20 with just one pot!
Cheesy: There may not be any actual macaroni in here but there’s definitely loads of cheesy goodness! No one will even notice it’s low carb.
Versatile: This is the kind of low carb side dish you can serve with just about any meal! We love this one for weeknight dinners, whether I’m cutting carbs or not.
Ingredients, Swaps & Tips:

- Cauliflower: This really is such a versatile veggie. Pretty neutral flavored after boiling and when you chop it up into macaroni-sized pieces and coat it in cheese, it gets the job done.
- Cheese: We’re using a mix of cheddar, Monterey Jack, and cream cheese but you can swap out the cheddar and Monterey jack for something like smoked gouda or gruyere for a different flavor.
- Hot Sauce: This doesn’t make the sauce spicy – just helps to balance out the flavors.
- Spice: I always add a bit of ground mustard powder to my cheese sauce for an extra boost of flavor, but if you don’t have it on hand, it’s fine to skip it. Ground nutmeg works well too.
- Bake It: We usually just go the stove top route, but you can aslo spread this in a 9×9 and bake for 10 minutes after topping with more shredded cheese.
- Crispy Topping: Mix ¼ cup almond flour with 1 tablespoon melted butter, ½ teaspoon garlic powder, and ¼ teaspoon garlic salt. Sprinkle over the baked version and broil for 1-2 minutes until golden.
Step by Step:

Chop the cauliflower florets into small macaroni-sized pieces. This really helps set the tone for this dish!

Boil the cauliflower until tender and then drain the water and return the cauliflower to the pot.

Stir in the remaining ingredients until everything is melted together. Turn the heat on low, if needed, to melt the cheese.

Season to taste and dish it up!
Storage:
Fridge: Store in an airtight container for 3-4 days.
Reheat: Warm gently on the stove with a splash of cream to loosen the sauce.
Freeze: Although you can freeze this the cheese sauce may separate and the texture won’t be the same.
Serving Ideas
We serve this up as a side dish just like we would traditional macaroni and cheese. It goes great with our crispy sour cream and onion chicken or alongside our brown sugar pineapple ham in the crockpot.
You can serve this cauliflower mac and cheese as a side dish or even as a main dish. Upgrade it with a protein like grilled chicken or pork chops!
This is a great low carb side for a BBQ or when you’re grilling out. It’s also great for lunch with a side salad.
Try topping it with crumbled bacon bits, green onions, or more cheese..
For picky eaters, try mixing some cooked macaroni in with a bit of the cauliflower until you’ve converted them into cauliflower lovers.

Think about what you are posting before you post it! You call this Califlower Mac and Cheese. There is no MAC in the recipe! Therefore it is Califlower and Cheese! The education system has failed you.
Karly Campbell says
And yet you’re the guy on the internet policing what other people call their recipes. 🙂
kim says
could i use cauliflower rice for this recipe?
Karly Campbell says
You can, just adjust the cook time so the cauliflower isn’t overcooked. You’ll also have more of a cheesy rice vibe since the texture will be different. 🙂

Gail Killian says
I was going to make the cauliflower Mac and cheese. I found Roth Havarti at the price of $8.00 for 6 oz. this price is too much for my family. I couldn’t find Roth Grand Cru. Is there a substitute cheese that doesn’t cost so much, and is easier to find.
Thanks
Karly says
Hi Gail! Sorry to hear that – Havarti tends to be a bit pricier than the standard bricks of cheese you’d find with all the packaged shredded cheese. I’m not sure if other brands will be any cheaper. Grand Cru is very similar to Gruyere cheese, but that one can also be a little pricier. I love to splurge on good cheese, but totally understand if it’s not in the budget. You could sub in any cheese you like here – freshly grated cheddar would be fine and if you add a bit of grated Parm it’ll add some extra flavor. 🙂
Sabrina says
great grown up mac and cheese, I don’t think havarti or grand cru is in kids version reight? and with all that cheese, there’s no need for pasta, cauliflower works almost seamlessly so thank you for wonderful recipe!
Cathleen @ A Taste of Madness says
So mac and cheese without the mac? I am totally in. I have been seeing cauliflowers on SUPER sale at the grocery store, and I have always been tempted to buy some, even though I had nothing in mind. Now I do!!
