January can get feeling long if you’re starting or returning to a healthier eating plan, and I created this Low-Carb Ham and Cauliflower Casserole au Gratin on a January day a few years back when I wanted some low-carb comfort food. I had ham and cauliflower in the fridge, and thoughts of Low-Carb Twice Baked Cauliflower gave me the idea for this casserole with lots of cauliflower with ham, cream cheese, Greek yogurt, Parmesan, green onion, and cheese. I’d love this delicious low-carb dinner for a cold winter night!

Of course I had to include this one when I updated my collection of 20+ Delicious Low-Carb and Keto Casserole Recipes recipes. There’s not much I don’t love about low-carb casseroles, but one of the biggest reasons I love to make them is the way they guarantee leftovers. And most low-carb casseroles also freeze well, including this one. (Did you know there’s a recipe index page for things that Can Freeze? I love to pull dinner out of the freezer when I don’t want to cook!) This Low-Carb Ham and Cauliflower Casserole au Gratin has been wildly popular; hope you enjoy trying it if you haven’t made this one yet!

And since this blog is for all types of carb-conscious diets, I also have some good low-glycemic casserole recipes on the site that might contain ingredients like brown rice, quinoa, or beans. Check out the index page for Casseroles if you want to see all my casserole recipe ideas. And we are half-way through the month of January people; let’s celebrate that!

You need at least 6 cups of cauliflower, cut into small pieces. Cook the cauliflower in boiling salted water until it’s just getting soft; don’t overcook. Drain the cooked cauliflower well (at least 5 minutes). While the cauliflower cooks, cut up two cups of lean ham. Soften cream cheese in the microwave for a minute or so, thenmix in the Greek yogurt (or sour cream), Parmesan, and sliced green onions.

Mash the cauliflower slightly (in the pan you cooked it in) then stir in the sauce mixture so it’s completely mixed with the cauliflower and gently mix in the ham. Season to taste with fresh-ground black pepper. Spray the baking dish with nonstick spray or olive oil, put the casserole mixture in in the dish, and sprinkle with cheese. Bake 30-35 minutes or until the cheese is completely melted and starting to brown and the mixture is hot throughout and starting to slightly bubble.

Let sit about 10 minutes for any liquid in the dish to be absorbed, then serve hot and enjoy! This will keep in the fridge for a few days and reheats well.

Low-Carb Ham and Cauliflower Casserole au Gratin

Ingredients:

  • at least 6 cups cauliflower flowerets, cut fairly small (1 large head cauliflower or 1 1/2 small heads)
  • 1/2 tsp. salt (for water to cook cauliflower)
  • 2 cups diced ham
  • 4 oz. cream cheese, softened
  • 3/4 cup Greek yogurt
  • 2 T finely-grated Parmesan cheese
  • 1/4 cup thinly sliced green onions
  • fresh ground black pepper to taste
  • 3/4 cup grated cheddar cheese (or more, depending on the size of your dish)

Directions:

  1. Preheat oven to 350F/180C. Fill a medium-sized pot half full with water, add 1/2 tsp. salt, and start to bring to a boil.
  2. Cut up the cauliflower into small flowerets, discarding the leaves and core. Put cauliflower pieces into the water and cook at a low boil until the cauliflower is starting to get barely sort. Check it often and don’t overcook; the cauliflower will soften more in the oven.
  3. While cauliflower is cooking, cut the ham into very small cubes and slice green onions. Put cream cheese into a glass dish or measuring cup and soften it in the microwave for a few minutes. (Or you can soften it on top of the pre-heating oven if you don’t have a microwave.) When cream cheese is soft stir in the Greek yogurt (or sour cream), Parmesan, and sliced green onions.
  4. When cauliflower is cooked enough to start to soften, pour into a colander placed in the sink and let it drain well (at least 5 minutes; don’t rush this step)
  5. Put the drained cauliflower back into the pot you cooked it in and mash with a potato masher until it’s barely mashed with quite a few chunks left. Stir in the sauce mixture and combine well with the cauliflower; then gently mix in the diced ham. Season to taste with fresh-ground black pepper. (I didn’t use salt because the ham and the Parmesan are both salty.)
  6. Spray glass or crockery casserole dish with non-stick spray or olive oil. (I used a glass casserole dish that was about 8″ x 10″.) Pour cauliflower mixture into the dish, spread out evenly, and sprinkle with the cheese.
  7. Bake 30-35 minutes, or until the cheese is melted and lightly browned and all the mixture is hot throughout and starting to bubble. Let sit 10 minutes for any liquid to be absorbed, then serve hot.
  8. I am assuming that this freezes well, but I still haven’t tried freezing it because I never have any leftovers.

  1. Just made this for my family and WOW! I was very skeptical because my previous attempts at using cauliflower as a "faker" have been major flops. When I put it in the oven I was sure I would be eating sugar free jello for dinner, but when I opened the oven to check on it 30 minutes later a delicious smell wafted out! The taste did NOT disappoint! I'll be adding this to our regular menu! Thanks so much for the wonderful recipe!

  2. Cristin, I know what you mean about those "not quite right" cauliflower recipes. Glad you liked this one!

  3. I found your recipe on Pinterest and tried it out today for lunch. I've started the first phase of the SBD and was tired of eating eggs and fish for the past few days. This was delicious. Thank you for sharing. I marked your blog and will be coming back for more ideas.

  4. This is a really great recipe Kalyn!! My hubby and I make this at least once a month. Thanks!

  5. Toni, so glad you like it!

  6. I LOVED this recipe! I've been on South Beach for three weeks and still really miss potatoes, which are my favorite food. This recipe did a great job of making me feel like I was eating a yummy potato casserole. Thank you!

    Mine easily filled a 9X13 baking dish, by the way.

  7. Heather, so glad you enjoyed it!

  8. I started making this recipe about six months ago and just LOVE it!!! I play around with it a lot too. My partner and I both love spicy food so I add sautéed jalapeños to the cream cheese mixture instead of the spring onions which is always tasty! We've tried adding broccoli to the mix too which gives it a rich color and another nice dimension.

  9. Hannah, love hearing how you've switched it up!

  10. This recipe is delicious! I tasted it cold and it reminded me of like a potato salad and baked was like eating scalloped potatoes and ham without all the guilt. Thanks so much for your great recipes!

  11. Used goat cheese in place of the sour cream and some chopped green chilies, made for a yummy twist

  12. Suzanne, that sounds good to me!

  13. This is delicious! My husband and I have it almost once a week. I use turkey ham and I put 1/2 the mixture into the casserole, add 1/2 the cheese and then the other 1/2 of the mixture and top with the rest of the cheese. It makes it seem cheesier.

  14. Delicious! I used mostly cauliflower, but part broccoli, and finely diced onion instead of green onions. I also tried a bite with a tiny bit of spicy brown mustard and it was really good,so next time I might add a little to the recipe.

  15. We really enjoyed this; another keeper recipe from you Kalyn!

  16. Hi, Kalyn – really appreciate and enjoy your recipes, especially the chicken mock enchilladas. Question about this recipe: I can't have yogurt – do you recommend any particular modification or substitution for that? (ie: more cream cheese?)

    • Glad you are enjoying the recipes! There is a lot of yogurt in this so I wouldn't replace it all with cream cheese unless you thin it. If you can have sour cream, that would be my first choice to replace the yogurt. You could also use pureed cottage cheese to replace the yogurt. If neither of those work I'd definitely thin down the cream cheese with milk or water and maybe use a bit less than the recipe calls for yogurt. Good luck, hope one of those ideas will work.

  17. Making it right now. Can't wait to taste it!!!!!!

  18. Can you steam the cauliflower? Or will you not get the desired result?

  19. I've been eating low carb for 4 years now and am running out of good recipes. This is THE BEST LOW CARB RECIPE ON THE PLANET. It completely satisfies that cold weather, cheesy, hot comfort food craving. I made it for my girlfriend who eats anything and everything under the sun loved it equally and couldn't believe it was low carb. Thank you for changing my life!!!! This will be my once a week go to.

  20. I tried this last night and it was Great! My husband even took some for lunch, which he's never done before with anything involving cauliflower. I did use Laughing Cow pepper jack cheese, yum. Tonight we are trying your ground beef and sauerkraut soup. Thanks so much for your blog, it's making phase one very easy and delicious!

  21. Made this yesterday and even my picky eater gobbled it up. Definitely a keeper. Thanks for sharing!

  22. Hi, Kalyn. My husband loves cauliflower but hates mashed potatoes. Do you think this would work if I didn't mash the cauliflower? Several people have said this reminds them of a potato casserole. In my husband's case, that would be a negative. But he does love all the ingredients.

    • The cauliflower is barely mashed here, still quite a few big pieces of cauliflower, and I think it would be fine if you wanted to mash it even less than that too. Hope you enjoy!

  24. Has anyone froze this before? I was wanting to make it into a freezer meal but I wasn’t sure if the cauliflower would be ok? 

  25. Just made this today, it was AMAZING!!!!! I used good Cabot white cheddar, gruyere, and a terrific smoked ham. SO good, I’m already thinking about leftovers for lunch 😉

  26. Love this recipe!! Have tried several times and my husband eats it up every time. One thing I tried with great results is sprinkling a small amount (1 – 2 TBLS.) of breadcrumbs on top before baking. I find I prefer roasted/baked Cauliflower to boiled – I can never get all the liquid out if I boil it!

  28. So delicious! 
    It be nice to see carb count… I know that may vary depending on ingredients, but it would be awesome to see the counts on YOUR version as a guide or references.

    • I’m not able to provide nutritional information for the recipes for several reasons, including the additional time it takes, the difficulty in doing it accurately, and the sheer number of recipes on my site. If you look after the recipe itself, I give two links (where it says “Nutritional Information”) for suggestions of two ways to get that information. That’s all I can do at this time.

  29. I steam my cauliflower instead to boiling in salted water.

  30. This tasted a lot like Mac N Cheese with Ham. I mean that in the best possible way. Delicious and simple to make.

    I used the microwave to soften the cauliflower.

  31. This casserole is absolutely DELICIOUS.  It puts macaroni and cheese to shame!  

  32. What type of ham do most people find the best to use? Ham steak?

    • I always buy the ham steaks that come in a 3-pack at Costco, so I’m sure that’s what I used. But I think any kind of ham will work except for thinly sliced deli ham.

  33. Can i replace the yogurt with sour cream?

  34. Do you have the nutritional count?

    • I have over 2000 recipes on the site and spend 6-8 hours most days working on the blog. I’m not able to provide nutritional information for the recipes for several reasons, including the additional time it takes, the difficulty in doing it accurately, and the sheer number of recipes on my site. If you look after the recipe itself, I give two links (where it says “Nutritional Information”) for suggestions of two ways to get that information.

      I just can’t edit over 2,000 recipes to add that info, and I know once I do it on one recipe people will expect to see it on every recipe.

  43. Made this today and it is delicious!! Didnt change a thing other than I didnt add green onions. Will definitely make this again!

  44. Can you use frozen cauliflower in this? 

    • I wouldn’t use frozen cauliflower, I worry that the casserole would be watery and the cauliflower too mushy since the frozen cauliflower is already partly cooked. But I know sometimes people do successfully use frozen vegetables in recipes where I’m skeptical it will work. I’d love to hear how it goes if you try it.

  45. I have this saved in Pinterest and it will NOT take me to the recipe, grrr, so aggravated!!! When I click on visit it takes me to just a large picture to pin. No recipe!! Please fix this. If anything happens to Pinterest I guess I lose my recipes!! This is a wonderful recipe! Takes some time to make it but worth it and no carbs. I always double it for a 9×13 pan.

    • Hi Deborah,
      Unfortunately anybody can copy one of my pins, make a new pin with it, and link it to any site they want. There is no way for me to fix that or even find the pin. But if you pin from the link at the top of my post (where it says “Click here to PIN) that’s the pin I made and it will always link to my site.

      Glad you have enjoyed the recipe!

  47. Wonder if this would be ok in a crock pot all day?

    • Truthfully I am not sure. I haven’t cooked anything like this in a crockpot. I wonder if it might be really watery, since the oven dries things out and the slow cooker creates more liquid. But if you are careful to drain the cauliflower really well it might work. Let me know how it goes if you try it!
