Cauliflower Mac and Cheese

Cauliflower mac and cheese is extra cheesy and melty! This tastes so much like the real deal that I bet you won’t even miss the carbs. 

cauliflower mac and cheese recipe

Truth time: Cauliflower is not potatoes. It’s not rice. It’s not pasta. It’s not pizza. 

I know that. I do.

It’s just that, when done right, it can be a really good sub for those things! Not everyone is going to love the cauliflower recipes, but if you’re on the fence about them, I highly encourage you to keep trying new versions! Because I am here to tell you that a really well done cauliflower recipe is gold.

This cauliflower mac and cheese recipe? It’s one of those really well done recipes and you are going. to. love. it.

This is NOT just your typical cauliflower drizzled with cheese sauce.

The first time I made this my daughter was helping cook dinner and she got really huffy about the cauliflower for mac swap. She insisted that she wasn’t going to like it. She complained right up until I made her try a bite.

You guys, the kid RAVED about this cauliflower mac and cheese. She said that it’s the ‘perfect amount of cheese’ and the ‘perfect blend of cheese’ and that it ‘tastes like really good mac and cheese.’ <— Those are all her words! She’s turning into quite the little foodie. And I totally agree with her. 

Let’s do this, shall we?

How to make this cauliflower mac and cheese recipe: 

We’re going to keep it extra simple, because we’re all busy and no one has time to spend hours whipping up a single side dish for dinner on a busy weeknight. 

This is a stove top cauliflower mac and cheese, so it’s literally ready from start to finish in about 20 minutes and that includes the time it takes to bring a pot of water to a boil. 

So, bring some water to a boil over high heat.

Chop up some cauliflower into macaroni sized pieces. The smaller size of the pieces is a big key to this recipe, so please don’t leave huge chunks.

I usually start with a bag of fresh cauliflower florets instead of a whole head, just because it’s easier and I’m all about a short cut. For the best taste and texture, I don’t recommend frozen cauliflower for this recipe.

Toss your cauliflower pieces into the boiling water and boil for 5 minutes. 

Drain away the water and return the cauliflower to the hot pan over low heat. Add in some heavy cream, cream cheese, cheddar, monterey jack, ground mustard, and salt and pepper.

Stir this all together until the cheese has melted and everything is well combined, gooey, and irresistible. 

The second key factor in this recipe that differentiates it from your usual steamed cauliflower with a drizzle of cheese sauce to cauliflower mac and cheese is the fact that every little bite is covered in the cheese sauce, just like it would be if this were actual mac and cheese.

Is cauliflower mac and cheese good? 

If you like cauliflower even a little bit, I imagine you’ll LOVE this recipe.

Some people really hate cauliflower and if that’s you, you might not like this recipe.

The cheese really hides the cauliflower though and the texture is a bit softer since it’s boiled, so I would recommend trying this.  It’s truly one of our favorites and we think it tastes amazing.

    Thanks for the recipe! I only had a 12 oz bag of riced cauliflower, so used just one cup shredded cheese and everything else the same except used half and half instead of cream.
    Cooking riced version 5 minutes did not overcook it.
    Put under the broiler to get some crispy goodness, YUM!

  2. Leslie Ann

    This sounds yummy! Want to try it, but we gotta watch hubby’s blood pressure. Do you think it would work well with half and half instead of heavy cream? I would also have to try and find fat free cheeses.

  3. I added chopped bacon when I added the cheese (don’t used pre shredded cheese as it has potato starch, which adds carbs) and I added some chopped chives once it was plated. Everything is better with BACON!!!!!!!

  4. I’m making this tonight, and adding some grilled chicken and then baking it with cheese and crumbled bacon on top to make it a casserole and a main dish.

  5. My daughter made this for us last night and it was seriously so good! Wonderfully simple and delish!

  6. Yep…this is it…the BEST cauli mac and cheese!!! And I’ve probably tried at least 10 different recipes for this over the last 8 years!

  7. Thank you for this! My husband just finished radiation and chemo for throat cancer. So finding things he finds that are appetizing as well as easy on his throat has been challenging. He asked for seconds of this and raved about it!

  8. This recipe is so totally amazing!! My kids even loved it and they are super picky. I recommend adding a couple of drops of truffle oil for a super-extra-tasty Mac and cheese experience

  9. This is great! Is it pasta. No. But it makes an excellent side for pork chops without all those carbs! Great job!

  10. Made this with some chicken thighs one night and had leftovers with ribs the next! Soooooooo devious! Will make again.

      I’ve never tried it with frozen riced cauliflower, so I’m not sure how long it will take to cook.

      1. Hannah Soulia

        I can’t find any regular cauliflower in any of my stores at the moment, is it okay if I use riced cauliflower instead?

        1. Karly Campbell

          I’ve only made this with the larger pieces, but riced should work if you don’t mind the smaller texture. You’ll want to adjust the cook time a bit as the rice will cook faster than larger pieces.

          1. Renee Button

            I used riced cauliflower, and waited until water came back to boil and boiled it 5 minutes. It turned out perfectly!

      1. Renee Button

        It made 24 ounces, so 6 4-ounce servings. I just tested 4 ounces by itself, and it filled me!

    1. Delicious! I didn’t have dry mustard so substituted stoneground mustard to taste. Thanks for the recipe.

  11. I was looking for the perfect cauliflower mac to make for my mac and cheese adoring Type 1 diabetic daughter. I’m excited to try this one.

      1. Courtney Gallucci

        It tasted kind of sour..does cauliflower always do that. Idk I just didn’t care for it but I’m sure if it was macaroni I would of liked it. Gotta get used to this Keto life lol

    1. It’s really good.. no joke. I added some chopped onions heated just until translucent. Thank you I loved it !!
