Ham and cauliflower casserole is the perfect way to use up that leftover ham! It’s creamy and rich, and so easy to make. It’s a crowd pleaser too.
This keto cauliflower casserole is the perfect answer to that age old question: what do I do with all this leftover ham???
If you cook ham for Easter or Thanksgiving, or any other holiday meal, bookmark this recipe now and don’t lose sight of it. You will be so glad you did!
Ham always makes so much. Even a “small” ham feeds a veritable army. And I am sure I am not alone when I say that the leftovers can be overwhelming.
So we need any and all recipes to use it up! Be sure to also check out keto ham and cheese scones, and keto baked asparagus for more tasty ideas.
Is ham keto?
So let’s first discuss ham, and whether or not it’s appropriate for the keto diet. The truth is that it depends.
Ham is a cut of pork from the thigh, and it’s usually cured for longer shelf life and preservation. It may or may not be smoked as well. So it really depends on how your ham is treated before you purchase it.
Many commercial hams are cured with a brine of salt and sugar, amongst other additives. Which means that some hams can have up to 4 or 5 grams of carbs per serving, even without the sugary glazes.
It’s important to be a label reader and choose ham with the least amount of carbs. Some can even have 0g, if they are cured with salt brine or simply smoked.
Ham and Cauliflower Casserole Inspiration
My husband’s brother sent us a gorgeous heritage breed ham from Zingerman’s for Easter. Of course, the very first thing I did was flip it over to look at the nutritional information. Phew, only 1g carbs per serving!
I am not a huge ham lover, but this was among the best I’ve ever had. Rich and flavorful, and no sugary sweetness. But as always with ham, it was far too much for one dinner.
We’ve all been picking at it daily, often eating it for breakfast with an egg on top. But I wanted to do something else more interesting with the leftovers. I saw this Ham and Hashbrown casserole on Salty Side Dish, and thought I could do something similar with cauliflower.
How to make Keto Ham Cauliflower Casserole
This is a super easy keto side dish that takes only 6 ingredients. It’s full of flavor and even my kids loved it. Big win!
Shred or coarsely chop the cauliflower
You could make this keto cauliflower casserole with cauliflower rice. But I wanted more texture than that. So I popped the florets in my food processor and pulsed it until coarsely chopped.
You could also use the shredding blade of a food processor. Or you could simply use a sharp knife and chop them by hand.
Dice the ham
You want to get bits of ham in every bite so dicing it works best. The pieces should be no more than 1/4 inch to 1/2 inch in size (small dice).
Grate the cheese
You can use pre-shredded cheese but grating an 8 ounce block of cheddar is easy. And this way, you can be sure that there are no added starches or fillers.
Use a thickener
Unlike hashbrowns, cauliflower releases a lot of water during baking. So I recommend sprinkling in some glucomannan powder before baking. The liquids will thicken up more as the casserole begins to cool.
It’s the same trick I use for Keto Rhubarb Crisp!
If you can’t find glucomannan, xanthan gum may also work. Neither is required, but the casserole will be a little watery when it comes out of the oven.
Bake until bubbly
The casserole is done when the filling is bubbly, the cheese is browned, and the cauliflower is fork tender.
Let stand
This casserole is super hot straight out of the oven. I recommend letting it sit for 10 or 15 minutes before serving. This also gives the filling a chance to thicken up a bit.
That’s it, friends! This keto cauliflower casserole was a surprise hit in my house, with my middle child even coming back for seconds. That says a lot!

I made this as written, except for the addition of some minced onions for my onion-lovin husband, and it was great. Well seasoned with hearty portions. Thanks for a wonderful recipe.
I made this for dinner last night. It was easy and tasty! My head of cauliflower was a bit small so I subbed 4 ounces with broccoli.
Made this and we love it thank you!
My husband and I enjoyed the Ham and Califlower casserole thanks
I made this and used the same amount of Xanthan gum instead of glucomannan. It still came out soupy. Should I double that the next time I make it? It was still good.
I also added a packet of Goya Jamon which helped boost the flavor.
I worry that more xanthan gum would make it slimy…
It was delicious! I added a half cup of chopped onions for added flavor.
If I use fresh cauliflower, about how much volume is 24 oz. of cauliflower? Half a head? 2 cups chopped? Thanks!
This recipe already takes fresh cauliflower. You are much better off doing it by weight. But it’s more than you think… your amounts are very small. 🙂 It’s more like one large head or 5 to 6 cups.
This is delicious. Next time I will add the thickener though . Loved the addition of garlic
Could you add some cream cheese to thicken?
Feel free to experiment.
This is really good! I recently started subbing out the ham with the Kirkland Pulled Pork from Costco and it was even better. Thanks for the recipe!
I’m going to try this with zucchini, since I’m not that fond of cauliflower. Sounds like it will be fantastic.
This is sooo very good! Thank you for all your wonderful recipes!
This is so good! I made a big ham in the crock pot yesterday, so this will be perfect for tonight. I’m hungry for this now! Thanks!
I’m about to make this… I got caught before in a cauliflower tortilla recipe that 12 oz was measured and not weighed therefore I messed it up… I don’t see the info in the blog and I apologize if I missed it…. is it 24oz by wt or measured? I’m thinking by weight like a bag of prepackaged or frozen cauliflower. This looks delicious and know I will love it! I got caught with the darn free ham at the grocery store and now have a 12lb beast to use up… Boiling the bone at the moment for some ham pot pie and of course I will freeze some but it seems that it never makes it out of the freezer other than to be thrown out for being in there too long or needing freezer space… I am terrible!!! Thanks for your great recipes!
By weight. Ounces are a measurement of weight, no matter what. So… 24 ounces is 24 ounces.
Thank you!
I’ve made other keto cauliflower and ham casseroles, but this is definitely my favorite! My kids normally aren’t too wild about cauliflower and ham casseroles, but this one they were very complimentary of. Thank you!
Made this for supper and it turned out great. I added some onion and broccoli just because but it would have been good without. We really enjoyed it. It will become a regular.
