Keto Cauliflower Mac and Cheese: Easy, Creamy, & Delicious!!
I never realized how amazing Keto Cauliflower Mac and Cheese could be until I had this! This recipe is super cheesy, creamy, and made without pasta! It is the ultimate comfort food when you’re on the keto diet and very low in carbs!
How to make keto cauliflower mac n’ cheese
If anyone is skeptical about cauliflower in a recipe, I can assure you it is me. When my hairdresser, Paul, shared this recipe with me that he created, I was very skeptical. But this low carb macaroni and cheese recipe is everything! It will not only satisfy your craving for traditional mac and cheese, but it will also go above and beyond your expectations. The cheese sauce is super-rich, creamy, and easy to make. I love enjoying it as a main meal with crispy bacon crumbled on top or better yet, as a keto-friendly side dish!
Below, you’ll find step-by-step pictures with easy tips. Make sure to scroll to the bottom of this post for the full list of ingredients and detailed instructions in the recipe card.
Step 1: Preheat oven to 375 degrees F and grease a 9 X 13 casserole dish. Wash cauliflower and cut into bite-size florets (so that it resembles the size of mac noodles). Add water to a bowl with cauliflower and microwave then drain completely.
Step 2: In a saucepan, add butter, heavy whipping cream, and garlic. Add softened cream cheese and stir with a whisk until thoroughly combined.
Step 3: Add all your cheddar, mozzarella, Parmesan, and cream cheese stirring constantly reserving 1/4 cup of cheddar cheese for topping.
Step 4: In a large bowl, toss your steamed cauliflower florets with the cheese sauce so it is thoroughly coated.
Step 5: Pour cauliflower mac and cheese into a baking dish and top with the 1/4 cup reserved cheese, paprika, Italian seasoning, and parsley. Bake for 25 minutes. Enjoy!
Is cauliflower keto-friendly?
Yes! This is why it is such a staple ingredient in keto recipes! It has just 3 grams of net carbs per serving, making it super low carb and great for replacing pasta or noodles in traditional recipes. This recipe is only four net carbs per serving.
Tips for cooking cauliflower:
Cauliflower comes in many different forms, frozen, raw, in steam bags, riced, etc. so HOW you prepare you cauliflower will make a huge difference in this recipe.
You can purchase a whole head of cauliflower if you prefer, which is the cheapest option, then cut it down into small florets. When using raw cauliflower, you have a few different options on how to cook it.
You can:
- steam it
- boil it
- roast it
Roasting the cauliflower will give it a nice added flavor! Just take note that fresh cauliflower is dry, so you will need to add some fat like butter or oil to your cauliflower so browns nicely.
If you boil your florets, whether on the stove or in your microwave, it is important to make sure you let your cauliflower FULLY COOL before adding it to your cheese sauce. This will prevent your sauce from being watery or runny.
The best way to do this is to lay the cooked and drained cauliflower out onto a sheet pan. Then allow the steam to evaporate fully. Once it’s cooled and the steam is gone, you can continue with the recipe.
I find it is easiest to microwave my mini florets for 10 minutes in a bowl of water. This will allow the cauliflower to boil and soften up just enough without taking up too much time!
How to make a low carb cheese sauce
This keto cheese sauce is easy to whip up and results in a creamy, thick, and decadent sauce. Just be careful not to boil your cheese. This will cause the fat to separate from the cheese affecting the texture. Also, make sure you do not add your cheese to boiling cream. Adding the cheeses while the cream is warm rather than boiling will allow it to melt slowly, creating a creamy and, more importantly, smooth sauce.
Other keto cauliflower mac and cheese add-ins:
- I love adding crumbled bacon on top! It adds incredible flavor and a nice crunch!
- If serving this as a meal, you can add shredded, sliced, or diced chicken to your sauce along with the cauliflower.
- Diced ham would also be a great addition!
- Try adding some pork panko to the top to mimic “breadcrumbs.” (Pork panko is crushed pork rinds.)
Frequently asked questions
- “Why is my sauce gritty and not smooth”? If your cream was too hot when you added your cheese, it could affect the consistency of the cheese.
- “Can I make this ahead of time?” Yes, you can! Just store it in the fridge until you are ready to reheat it. It may take a bit longer to bake since it is colder.
- “Can I freeze this?” Yes, but keep in mind that freezing cheeses and cream may affect the consistency and texture of your sauce. I suggest laying a piece of plastic wrap directly over top of your casserole then follow that with tin foil and a lid. Allow it to defrost fully in the fridge overnight before baking then placing it in the oven while it is preheating so that it heats slowly. You may notice that the sauce is a bit grainy.
- “Can I use frozen cauliflower?” Yes, however, the texture will be different. Frozen cauliflower has more moisture in it, so it will not have the same “bite” as fresh cauliflower. Make sure not to overcook the cauliflower. You do not want mashed mac n’ cheese!

May have missed but how many net carbs for a serving?
The nutritional info is located at the bottom of the recipe card.
Looks incredible but I have a tough time with cream cheese. Is there anything I could substitute? Maybe ricotta? Thanks! Or half ricotta half cream cheese?
I’m not sure I’ve only made it as is. It might be worth a try.
Seth, I used cottage cheese and deleted heavy cream. It was amazing!! Hope that helps.
How much is considered 1 serving
The number of servings is listed at the top of the recipe card. I divide the recipe evenly by that number.
This is amazing! The best I’ve ever had. I did not have cream cheese so I subbed cottage cheese, left out heavy cream and Italian seasoning. Once prepared I topped with previously cooked chicken tenders. Kasey is an amazing recipe Developer. Thank you.
So glad you loved it! I appreciate your kind words so very much! Thank you!
One can’t have too many cauliflower recipes😉 and this one looks great!
I just made this tonight as part of my low-carb Thanksgiving meal. The recipe was fairly easy to follow, inexpensive, and most importantly, it’s delicious! The cheese sauce really masks the cauliflower taste, and anyone eating it wouldn’t miss the pasta. This is a winner (as every recipe I’ve tried on this site is!) and will go into my recipe collection. I love Mac and cheese and knowing that I can eat a low-carb version that is delicious makes my heart happy! Thank you for sharing!
You’ve made my day! I am so glad you enjoyed it and you’ve loved my recipes so far. I appreciate your kind words and that you took the time to rate the recipe.
Made this today and it was delicious
Hi Judy, so glad you enjoyed it! It’s one of my favorite recipes.
Made this tonight and it was absolutely OUTSTANDING!! Total gamechanger! Thank u so much for sharing!
Absolutely! Thanks so much for your kind words.
Made this to accompany smoked ribs and it was a ‘bullseye’! Could have accompanied rotisserie chicken, easily. Fiancé said not ‘mac and cheese’ but he loved the taste, make it again! For 2 of us, I cut recipe in half. 1/2 Recipe made 3 generous servings and he’ll eat the ‘leftover’ tomorrow! Delicious, can’t wait to try Reuben casserole and Philly Cheesesteak casserole! Thanks for the comfort food I can have!
