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!

  7. Put cauliflower into a baking dish and top with the three-cheese blend, or any cheese that melts well.

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.
