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!

Start by cutting up a head of cauliflower into bite-sized pieces and cooking it for exactly 5 minutes in boiling salted water. Drain the cauliflower very well. While you’re doing this preheat the oven to 375F/

Then put the well-drained cauliflower into a bowl (or back in the pan you boiled it in if you want to save dirtying another dish!) Add the butter to the hot cauliflower and stir to coat cauliflower with the butter. Then mix in the Parmesan and sharp cheddar.

Put cauliflower into a baking dish and top with the three-cheese blend, or any cheese that melts well. Bake for 20-25 minutes, or until the cauliflower is cooked through and cheese is all melted and nicely browned.

Serve hot and enjoy! This reheated especially well so if you’re a big fan of cheesy cauliflower you might want to double the recipe and make it as a Weekend Food Prep recipe to enjoy several times as a side dish.

Make it a Low-Carb Meal:

This would be a great low-carb side dish for something simple like Easy Low-Carb Garlic and Lemon Shrimp or Chicken Piccata with Fried Capers.

Easy Cheesy Baked Keto Cauliflower

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, yellow or white
  • 1/2 cup grated three cheese blend (or any cheese blend that melts well)
  • coarse-ground black pepper (optional; we didn’t use it but I might add some next time)


  1. Preheat oven to 375F/190C. We used an 8.5 ” X 11″ baking dish for this recipe.
  2. Bring water to boil in a pot that’s large enough to hold all the cauliflower.
  3. 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.
  4. When the water boils, add the salt and cut-up cauliflower, turn heat down to a low boil, and cook cauliflower 5 minutes.
  5. Drain cauliflower very well in a colander placed in the sink.
  6. 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. Then add the coarsely-grated Parmesan, sharp cheddar, and a little black pepper if desired.
  7. Put the mixture into the baking dish and top with the three-cheese blend.
  8. Bake 20-25 minutes, or until the cauliflower is cooked through and the cheese is melted and lightly browned. Serve hot.
  9. This will keep in the fridge for a few days and reheats well.


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. 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! 

  2. It irks me that you send us to a nutrition calculator to do what should be your work. It’s just lazy. If you are going to call it keto…back it up. P.S. The recipe analyzer doesn’t work.

    • 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.

      I am planning to add nutritional information, but not until the editing project is done. That will be starting be sometime in November 2019, but it will take time to get to all 2,000+ recipes. That is simply all I can do, no matter how many rude comments people leave demanding the nutritional information.

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

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

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

  6. 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.

  7. 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.

  8. 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.
