I created this 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!

What ingredients do you need for this recipe?

  • raw cauliflower
  • salt (for water to cook cauliflower)
  • diced ham
  • cream cheese
  • Greek yogurt
  • finely-grated Parmesan cheese
  • green onions
  • fresh ground black pepper to taste
  • grated cheddar cheese

How to Make Ham and Cauliflower Casserole au Gratin:

(Scroll down for complete printable recipe with nutritional information.)

  1. You need at least 6 cups of cauliflower, cut into small pieces.
  2. Cook the cauliflower in boiling salted water until it’s just getting soft; don’t overcook.
  3. Drain the cooked cauliflower well (at least 5 minutes).
  4. While the cauliflower cooks, cut up two cups of ham.
  5. Soften cream cheese in the microwave for a minute or so, then mix in the Greek yogurt (or sour cream), Parmesan, and sliced green onions.
  6. 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.
  7. Season to taste with fresh-ground black pepper.
  8. Spray the baking dish with nonstick spray or olive oil, put the casserole mixture in in the dish, and sprinkle with cheese.
  9. 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.
  10. 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.

Ham and Cauliflower Casserole au Gratin

Yield 6 servings
Prep Time 25 minutes
Cook Time 35 minutes
Total Time 1 hour

This Low-Carb Ham and Cauliflower Casserole Au Gratin is definitely a treat for low-carb and Keto comfort food.


  • 6 cups raw cauliflower flowerets, cut fairly small
  • 1/2 tsp. salt (for water to cook cauliflower)
  • 2 cups diced ham
  • 4 oz. cream cheese, softened
  • 3/4 cup Greek yogurt (see notes)
  • 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 (see notes)


  1. Preheat oven to 350F/180C.
  2. Fill a medium-sized pot half full with water, add 1/2 tsp. salt, and start to bring to a boil.
  3. Cut up the cauliflower into small flowerets, discarding the leaves and core.
  4. 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.
  5. While cauliflower is cooking, cut the ham into very small cubes and slice green onions.
  6. 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.
  7. 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)
  8. 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.
  9. Stir in the sauce mixture and combine well with the cauliflower; then gently mix in the diced ham.
  10. Season to taste with fresh-ground black pepper. (I didn't use salt because the ham and the Parmesan are both salty.)
  11. 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.
  12. 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.
  13. I am assuming that this freezes well, but I still haven't tried freezing it because I never have any leftovers.


You can also use sour cream if you're not a Greek yogurt fan; yogurt has just slightly less carbs. Definitely use more cheese if you'd like!

  1. Oh sweet holy Mary this was TO DIE FOR especially because we're in the middle of phase 1-well, half a week left 🙂 and I think we were all feeling like splurging 😉 I think it's good for phase one, but maybe just once a week? I dunno.I checked out the fat content, etc. ah, I don't care it's cauliflower! And Greek yogurt I SWEAR is the greatest thing that EVER happened to me omg! Very very good!!! Sharing with *everyone*!

  2. Cristy if you use the lower fat ingredients like I did you can definitely eat this for phase one. Some people have suggested replacing the lowfat cream cheese with an equal amount of Laughing Cow cheese, which would make it even lower in fat.

  3. I just found your website by accident and I am so glad I did. Struggling with the 'same old' SB phase 1 recipes, it's nice to find some fresh ones. I am going to try this, and several other recipes from the site, this next week.

  4. YES! I want to eat this right now. Are you sure this is phase 1???

  5. I made this last night and it was delicious! I was getting stuck in the chicken breast and green beans rut and this casserole was a welcomed change! Thank you so much for your awesome recipes!

  6. I know this will be good! I tried the twice baked cauliflower and loved it, who wouldn't like it with ham!

  7. Thanks for the nice feedback everyone. I like the idea of replacing the cream cheese with Laughing Cow.

  8. That looks so sinful but when you dig apart the layers it is made very thoughtfully. I love 'responsible cooking'! Very nice.

  9. Kalyn, a delicious recipe as usual. I don't often use fresh cauliflower, but rather the frozen florets. Is there anything I should do differently when using frozen cauliflower rather than fresh?

    • I don't think I would make this with frozen cauliflower. Since the frozen cauliflower is pre-cooked I think it would be overly done and probably too watery by the time it was done. (Let me know if you try it and I'm wrong, but personally I would use fresh cauliflower.)

  10. Hi Kalyn, looks like a great recipe – and I have everything in my Fridge! I think, I try and use a piece of The Laughing Cow (light Queso Fresco – I like it spicy) for part of the Cream Cheese, because its lowfat and low in Sugar and Cholest.
    Let you know, how it went.
    By the way, I made your Roasted Cauliflower With Red Bell Pepper, Green Olives… again a few days ago and it vanished in no time.

  11. Great!!!

  12. Oh. My. Goodness. I just made your Cauliflower Gratin with Sharp Cheddar last week and my DH was bowled over. This sounds amazing and I can't wait to try it!!! Thank you so much from those of us who try to trim our DH waistlines!

  13. Looks wonderful! How many servings does this make and what are the nutritional facts (calories, protein, fat, carbs) per serving?

  14. I am loving all of that cheese!

  15. Thanks Brenda, Joanne, and Deborah!

    The recipe makes about 6 main dish servings, but a moderate serving meant to be eaten with a green salad or some vegetables on the side. I haven't tried cooking with laughing cow, but I'm guessing it would work. The wedges are not one ounce though, they are .75 oz. so you'd need about 5.5 wedges to equal the same amount as the cream cheese. If you try it, would love to hear how it works.

  16. Looks delicious! The recipe "makes about 6 servings" — is that main dish or side dish servings? Also, could I use 4 laughing cow wedges in place of reduced fat cream cheese?

  17. I just finished making my way through a whole ham (last of it is in the slow cooker right now!), but now I'm wishinig I had more! This looks fantastic!

  18. I feel like this is the time when some willpower starts to wane, so yes comfort food is necessary! Bring on the cheese and cauliflower!

  19. I can't wait to try this! Looks amazing and has so many ingredients that I love.
