This is the Best Cauliflower Mac and Cheese you can make. I have tested several different recipes and this is still by far my favorite. Totally satisfying, keto-friendly, low carb, and easy to make. It will even satisfy your picky eaters as it tastes just like your favorite ultimate comfort food.
This low carb side dish is on repeat at our house- we just can’t get enough. I love how cauliflower is a versatile vegetable and can be used in numerous recipes. Cauliflower recipes have been trending for years since they’re low carb, nutritious, and basically serve as a blank slate for flavor.
WHAT YOU NEED TO MAKE THE BEST CAULIFLOWER MAC AND CHEESE
- Cauliflower – This recipe calls for one large head of cauliflower or two small heads. Fresh cauliflower is much better than frozen cauliflower rice for this keto cauliflower mac.
- Olive oil – You could really use any neutral oil that you have on hand.
- Salt + black pepper – One of the best parts of this recipe is the simplicity! It only requires minimal kitchen staple seasonings.
- Garlic powder – If you’re a huge fan of garlic, you could certainly replace this with fresh minced garlic for a stronger flavor.
- Onion powder – Onion powder can also be increased or decreased based on personal preference.
- Heavy whipping cream – Helps add to the creaminess of your low carb cauliflower mac. You could also use milk if you prefer, it may change the consitency a bit. Sometimes I’ll use both and divide them in the recipe.
- Cream cheese – If you’re trying to keep this cheesy cauliflower recipe on the healthier side, I would use a low fat cream cheese.
- Cheese – I like to use a combination of Cheddar, Monterey Jack and Gruyere cheese, but feel free to choose whichever cheeses you prefer. It is also a great way to clean out the odds and ends in the fridge.
MAC AND CHEESE SAUCE
This cheese sauce is my favorite and can eat it with just about any vegetable! It’s rich, thick, and has the comforting flavors of mac and cheese. This sauce is made with heavy cream, cream cheese, a combination of my favorite cheeses, and a few spices.
You can make this dish in about 30 minutes with only a few easy and simple steps. I like to wait until the cauliflower florets are done roasting before I make the cheese sauce so the cheese sauce doesn’t harden and only takes a few minutes.
ROASTING THE CAULIFLOWER
- Cutting the cauliflower into smaller uniform pieces will ensure they all cook at the same rate. I also love a few crispy pieces so I cut some into even smaller pieces. You can cut your cauliflower into bigger pieces if you prefer but you will have to roast them for a little longer or settle for a snap in the middle.
- Simply place the cauliflower pieces in an even layer on a baking dish lined with parchment paper or foil. Drizzle with olive oil, salt and pepper and roast cauliflower for 15-20 minutes.
Optional:If you are a lover of that char, like me, you can opt to switch it over to broil for a quick blitz of heat. Make sure to keep a watchful eye to prevent burning- especially if you used parchment paper.
MAKING THE CHEESE SAUCE
After you’ve achieved tender cauliflower, it’s time to make the gooey sauce. This is my favorite part! Use your favorite cheese combinations as long as it equals 2 1/2 cups total. This cheese sauce is straightforward to make.
- Whisk together the cream and cream cheese (make sure to cut into pieces so it melts faster) in a saucepan until combined.
- Add in the rest of the ingredients and vigorously whisk until combined and cheese is smooth. Once the sauce is melted, remove from the heat immediately. It is important to keep an eye because you don’t want to over cook it otherwise it will turn into a solid. All stovetops vary so this cheese sauce may cook a little quicker or slower depending on your stove.
- The last step is to combine it all together! Combine the cream sauce with the cauliflower pieces until they are well coated.
VARIATIONS
Cheese it Up- As stated in the recipe card, I prefer to use Cheddar, Monterey Jack and Gruyere cheese for this recipe. However, feel free to mix up the cheese to your liking. You could use parmesan cheese, sharp cheddar cheese, really anything that melts well. The more of a blend, the more flavor sophistication.
Add Protein– Turn this delicious cauliflower mac into a main dish by adding some chicken to it. You could even take it one step further by adding BBQ or buffalo sauce into the mix. Top with green onion and now you have a delicious buffalo cauliflower mac n cheese! Save time by buying a precooked rotisserie chicken at the store or using leftover chicken from another meal.
Some like Hot- Some folks like to sweat! Add chopped jalapenos, fresh or pickled, or diced green chiles to cheese sauce before tossing. Alternately, add 1 teaspoon of chili powder. Cayenne pepper, crushed red pepper flakes or paprika will also give heat and color.
Crunchies- Top your cauliflower mac with bread crumbs or crumbled cracker bits.
More Veggies– I try to sneak in more veggies wherever possible. This dish is great with green peas, sun dried tomatoes and even lightly sauteed mushrooms.
Tangy- Add a dollop of dijon mustard or prepared horseradish.
Storage & Leftovers
Store leftovers in an airtight container for up to 5 days.
To reheat, simply reheat in the microwave or even warm it up in the oven. If it seems a little dry, you could always add a splash of milk. You can also do this in a small saucepan over low heat on the stovetop.

The Best Cauliflower Mac and Cheese
Ingredients
- 1 head cauliflower, cut into small bite size pieces (think the size of gnocchi). 1 large head OR 2 small heads
- 2 Tbsp. olive oil
- 1/4 tsp. freshly ground black pepper
- 1/2 tsp. salt
- 1 tsp. garlic powder
- 1/4 tsp. onion powder
- 1 1/2 cup heavy whipping cream you could also use milk instead or use both, just divide them to equal 1 1/2 cups total.
- 4 ounces cream cheese; cut into small cubes or pieces
- 1 cup shredded cheddar cheese
- 1 cup gruyere cheese
- 1/2 cup shredded Monterey Jack cheese
- 1/4 tsp. paprika (optional)
Instructions
- Preheat oven to 425 degrees F. Place the cauliflower on a baking sheet coated with foil or parchment paper. Drizzle olive oil, salt, and pepper on the cauliflower pieces and coat well. Bake for 15-20 minutes or until the cauliflower pieces or softened. Some pieces will be darker in color.
- Once the cauliflower is cooked, in a large pot on low heat add the heavy cream and the cream cheese. Whisk until the cream cheese is melted. Add the remaining cheeses and continue to stir until all cheeses are melted. Add the spices to the sauce and incorporate- this process is quick and will take a few minutes. Once the cheesy mixture is smooth and comes to a simmer, REMOVE FROM HEAT and vigorously whisk.
- Add the roasted cauliflower pieces and stir until all of the cauliflower pieces are coated. Serve immediately and enjoy! Sprinkle paprika on top if you want some extra spice!
Notes
- You can use any cheese combination that you prefer. Cheddar, Monterey Jack and Gruyere are my favorites for this recipe. Make sure to use a total of 2 1/2 cups total.
- It is important to keep an eye on the cheese sauce because you don't want to over cook it otherwise it will turn into a solid.

Yummy! This recipe was a big hit here at the house! It was so delicious and tasty! Can’t wait to make this again!
Great recipe!! We love this even more than regular mac and cheese!
No matter which way I prepare it, my cauliflower Mac and Cheese always ends up soupy, with too much fluid after baking.
Hi Rebecca, thank you for your comment. It is very important to make sure you pat dry the cauliflower after you wash it- before you roast it. Also, if you use a smaller cauliflower, the sauce will seem like a lot. I hope this helps and thanks for trying my recipe!
This is the recipe I turn to when I’m craving something creamy, cheesy, and low carb! Love it!
We love roasted cauliflower in our home and I am sure we will love your version of mac-and-cheese with cauliflower. It looks so creamy and delicious.
This was amazing but instead of roasting the cauliflower in the oven I rubbed it with an olive oil and Cajun seasoning mixture and smoked it at 275 for 50 minutes the flavor was outstanding I couldn’t stop eating the cauliflower after it came off the smoker I will definitely be making this again
That is such a great idea Becky! I will have to try smoking the cauliflower the next time I make this recipe. So glad you loved this cauliflower Mac and cheese, thank you!

This recipe sounds amazing. Can I make it and freeze it?
Hi Marta! Yes you can make this ahead and freeze the Mac and cheese for up to 3 months in an airtight container or heavy duty ziplock bag. If the Mac and cheese seems to be watery when reheating, add more cheese. I hope you love this recipe! 🙂
Hi, I’m trying this recipe for my son on Thanksgiving
I am wondering if it freezes well? It will only be him and me eating it, so I know we will have some leftovers.
Thank you for your help!!
Hi Lyn, that is great! You can freeze this Mac and Cheese for up to 3 months in an airtight container or heavy duty ziplock bag. They Mac and cheese may seem watery when reheating, if it does add more cheese. You can also keep this refrigerated for up to 3 days. I hope you love this recipe and Happy Thanksgiving!
Ok! Thank you for your speedy response (especially right around the holidays!)… I’m very excited to try this – my 4yo son has never had Mac & Cheese
I just wanted to come back and say this recipe is SO yummy! I had never cooked cauliflower (maybe never had it), but I prefer this now over traditional Mac & Cheese.
Thanks for the recipe and help!
Hi Lyn, I am so happy to hear that you loved it!! Thank you for trying my recipe and I hope you had a wonderful Thanksgiving!
Ratio of cauliflower to sauce was not equivalent. Came out very saucy, but delicious!
I made with mango habanero bacon and also added diced jalapeños. I wasn’t concerned about gluten free/keto, so I also added penne pasta and topped with panko bread crumbs, more crumbled bacon, and then added smoked paprika to the top. So yummy!
That all sounds like great additions to this Mac and cheese! So glad you loved it and I’ll have to try it with pasta! Thanks for trying my recipe 🙂
This will for sure be in the rotation! TracyThx for sharing this recipe!
Thank you Tracy! I hope you love this Cauliflower Mac and Cheese, it’s one of my favorites!

Question: Would it work if follow all of the directions and then bake it in the oven? I’d like to also add crushed pork rinds with butter and Parmesan on top for a little extra crunch. Making this for Easter dinner!
Hi Marla! Yes, you could definitely do that 🙂 I bake this mac and cheese almost every time and it comes out delicious. I usually bake it at 350 degrees F. The pork rinds and parmesan sound like a delicious idea! I hope you enjoy this recipe and Happy Easter!
