In my office I have a small bookshelf next to the desk that has 13+ years worth of notebooks with recipe notes and blogging info. And some of the recipe notebooks are from long before I ever heard of blogging. I re-discovered this recipe for Easy Cheesy Baked Keto Cauliflower in one of those notebooks and was intrigued by how easy it was, and when we tested the recipe we absolutely loved it! My old notes had no information about the source of the recipe so I can’t give any credit to anyone, although we changed it a bit when we made it for the blog.

And let’s be honest, I did wonder if this blog needs another easy cheesy cauliflower recipe since Twice Baked Cauliflower, Cauliflower Gratin, and Cheesy Baked Cauliflower Tots are all such popular recipes. But the absolute easiness of the recipe, combined with the way it uses common ingredients, convinced me that many of you will like it. So grab a head of cauliflower, some butter, Parmesan, sharp cheddar, and a cheese blend and give this tasty side dish a try! And if you want to call it a casserole and eat it as a main dish, I think that would make a good dinner as well!

Before I give the recipe I want to say one more thing. This recipe uses a lot of cheese! If it seems like too much cheese for you, feel free to use the amount you prefer. I can’t see through the computer to tell how you adapt a recipe to your personal taste, honest. And you are under no obligation to make a recipe just because I share it here, so I hope the cheese police can refrain from criticizing!

Total Time 40 minutes

Easy Cheesy Baked Keto Cauliflower is a rediscovered recipe I first made before I even had a blog!


  • 1 large head cauliflower, cut apart into bite-sized pieces
  • 1 tsp. kosher salt (for water you use to boil the cauliflower)
  • 2 T butter
  • 1/2 cup coarsely-grated Parmesan
  • 1 1/2 cups grated sharp cheddar (see notes)
  • 1/2 cup grated three cheese blend
  • coarse-ground black pepper to taste


  1. Preheat oven to 375F/190C.
  2. We used an 8.5 " X 11" baking dish for this recipe. Spray baking dish with olive oil or non-stick spray.
  3. Bring water to boil in a pot that's large enough to hold all the cauliflower.
  4. While the water comes to a boil, cut up the cauliflower, cutting away and discarding the core and leaves and cutting cauliflower florets into bite-sized pieces.
  5. When the water boils, add the salt and cut-up cauliflower, turn heat down to a low boil, and cook cauliflower 5 minutes.
  6. Drain cauliflower very well in a colander placed in the sink.
  7. When cauliflower is well-drained, put it into a bowl (or back into the pan you used to cook in) and add the butter. Stir to melt the butter and coat the cauliflower.
  8. Then add the coarsely-grated Parmesan, sharp cheddar, and a little black pepper if desired.
  9. Put the mixture into the baking dish and top with the three-cheese blend.
  10. Bake 20-25 minutes, or until the cauliflower is cooked through and the cheese is melted and lightly browned. Serve hot.
  11. This will keep in the fridge for a few days and reheats well.


Use yellow or white sharp cheddar for this recipe.

I rediscovered this recipe in an old notebook with no source listed, but it was adapted with help from Jake and Kara.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Easy Cheesy Baked Keto Cauliflower is a good side dish for any low-carb diet or Keto diet, but it’s probably too high in fat for the South Beach Diet. I’m sure you could make a tasty version with less cheese if you prefer.

  1. As a Cheese cop, I’m going to have to pull you over and cite you for insufficient cheese quantity on this.
    Ok, kidding.
    Great recipe. There’s no such thing as too much cheese so good for you!
    Thanks for posting.

  2. Loved this!  My husband was skeptical that cheesy cauliflower would be this good without a bechamel sauce, but this we agreed this was even better than your classic cheesy cauliflower dish.  We ate this with grilled chicken.  Used a high-quality sharp cheddar.  This would be good when you are craving comfort food, as well! 5 stars!

  3. Made this to go with pulled pork tonight .
    When you say 9g of carb is that for one portion or for the whole recipie , i easily get confused

    • Nutritional information is always given per serving. This recipe has 9 total carbs per serving, but 3 grams of fiber for 6 net carbs. Hope that helps.

  4. Made this last night, very underwhelming. For the price of cauliflower I need it to be delicious, there are far better recipes available. 

    • Did you use good quality sharp cheddar? The flavor here is from the cheese, and it was definitely delicious with the cheeses that I used.

  5. I am so lucky to get great recipes from people like you. I just put i the ingredients I have on hand and it takes me to so many options. Thank you so much for sharing your recipes! I have become a better cook in this quarantined time thanks to your efforts. My stomach and I appreciate you!

  6. Great recipe!
    I found your recipe when looking for something to make with some leftover steamed cauliflower and broccoli that we had from dinner last night (it was slightly undercooked). We didn’t have 3 cheese bend, so used mix of sharp and mild cheddar. I can also see this being good with a variety of other cheeses!
    I adapted by  starting with tossing it in a little olive oil as that was what was on hand). I also added 2 cloves of grated garlic in with the cheeses (which admittedly I did not measure, but used what looked about right). I liked the flexibility of this recipe to use it as a guide with what I had on hand.  
    It paired well with baked pesto chicken (inspiration from another recipe of yours I found after looking at this one!) and a side of sautéed beet greens.
    Thank you so much for sharing it!!

  7. Curious where the sugar is coming from in this recipe?  I tried it tonight and it was delicious – thank you!

  8. I try to balance my cooking between healthy and tasty. If I can get both, then it’s even better. I realize that some people have specific dietary needs and I sympathize with their plight. Some people in MY family also have specific dietary requirements. However, as the cook, I feel that it is MY responsibility to see to it that those requirements are met, not someone else’s. Now, I am speaking for myself here and not for anyone else. But to be want to be able to use someone else’s recipe and, at the same time, demand that they provide more info to meet your desires or needs is extremely rude and self centered. Let’s all consider just appreciating what is being provided (and at no charge) and be thankful for it. If it does not appear to meet your needs, feel free to try a different recipe. But please, let the rest of us just enjoy the work that others have done for us and be thankful for it.

    • Pat I do appreciate your attitude about it. But the good news is that I am now starting to calculate nutritional information on the recipe (as I promised I would!) This recipe now has it.

    • Thank you, Kalyn, for all of the work that you have done putting together all of these delicious recipes and sharing them with us. You enrich all of our lives by your efforts and I just wanted to let you know that there are so many people who, though they may not take the time to say so, really appreciate it.

  9. Your recipes look amazing!  I can’t wait to try them.  Thank you so much for posting them!  I appreciate all your hard work!

  10. Wow. Just wow.
    Thank you so much for everything you do, Kalynn. You have been my go to for recipes for YEARS! You have seen me through Somercizing, South Beach, keto, low carb, etc,. and I have nothing but appreciation for the effort and time you put in to keeping up with all the changes in eating trends/styles. YOU ROCK!!!

  11. Wow. Just wow.

  12. Lynda, thank you very much! I am surprised by people who are so demanding about it (and I am ready to start doing it in just a few more weeks) but I certainly appreciate people who are more willing to take responsibility for their own eating choices! Hope you enjoy the recipes!

  13. I made this and it was great- yes, I am on Keto. Yes, I would have liked nutrition info. But i get it! Life happens and you are working on getting that updated. In the mean time, I will enjoy your delicious recipe and wait patiently for the update. Thanks for sharing! 

  14. I’ve tested the recipe, taken photos, and written it up for you, so I wouldn’t say I’m lazy. But I do have limits for what I can do.

    I wish there was an easy way for me to get nutritional information on all the recipes. This post talks about my efforts after I switched my blog from Blogger to WordPress and had to edit 2,000+ recipes. I have been working on that for nearly two years now, while trying to keep up with the blog.

    [edit November 2019] I have now started the huge job of calculating nutritional info and this recipe is done.

    • Wow, some of these comments are so rude and demanding! I don’t understand why people think it’s your job to provide nutritional information? I have read on several blogs that they do not do that and direct people to fitness calculators. I’m sorry you’re getting so much negative feedback. This is the first time I’m not your page and I couldn’t help but respond. I think this recipe looks delicious!

  15. My family (husband gags) hates cauliflower so I thought I’d substitute broccoli. It was great!. Delicious!

  16. Made it, loved it, super easy, turned out perfect!
    I will be making this again😊

  17. This looks great, and the perfect alternative to the cauliflower cheese I make. Will definitely be trying this soon.

  18. Anyone who claims that any recipe contains ‘too much cheese’ is a liar and a fraud, and you don’t need that kind of negativity in your life.

    Seriously, it looks amazing. Gonna try this one soon.

  19. Would there be any downside to using frozen cauliflower? I’m wondering if it would tend to retain too much water, but I am often too lazy to cut up a cauliflower and then clean up the mess of crumbs I’ve left behind. 

    • Truthfully I don’t have much experience cooking with frozen cauliflower. Definitely I think fresh cauliflower would be best. But thawed frozen cauliflower might work probably with a bit shorter cooking time. Would love to hear how it goes if you try it.

  20. I like the cauliflower in this casserole, but the ‘amount’ of cheeses used in this dish, by far, cancel out the health benefits of using cauliflower. What’s the fat & the sodium content per serving?

    • I guess you missed my remarks requesting no “cheese police” comments. If the recipe doesn’t appeal to you, simply don’t make it.

    • Clearly some people are looking for a magic healthy dish that’s going to make the weight fall off. Keto uses fat but no sugar. If you look up a cheesy cauliflower dish then criticize about the cheese, maybe you should look up “healthy” recipes instead. I am excited to give this a try out. Thinking of chopping some almonds to go on top to make it crunchy since I’m doing keto and can’t use crackers.
