Ham and Cauliflower Casserole Au Gratin is definitely a treat for low-carb comfort food and this is one of my personal favorite casseroles!
PIN Ham and Cauliflower Casserole au Gratin to try it later!
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 Twice Baked Cauliflower gave me the idea for this casserole with lots of cauliflower combined with ham, cream cheese, Greek yogurt, Parmesan, green onion, and cheese. I’d love this as a delicious low-carb dinner for a cold winter night!
Of course I had to include this one when I updated my collection of Low-Carb and Keto Casseroles 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, and how I love to pull dinner out of the freezer when I don’t want to cook! (You can use the category for Can Freeze to find more dishes that freeze well.)
This low-carb casserole with ham and cauliflower has been wildly popular on the blog; hope you enjoy trying it if you haven’t made this one yet!
What ingredients do you need for this recipe?
(This is ONLY a list of ingredients for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete 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
What kind of ham should you use for this casserole?
If you want this recipe to be Keto, be sure to choose a ham without added sugar. I use thick ham steaks from Costco, but thick sliced deli ham, and cut up cubes from a whole ham will also work.
Can you make this recipe with frozen cauliflower?
I’ll be honest and say I am not much of a fan of frozen vegetables, and I’d prefer freshly-cooked cauliflower for this. But there are some comments on this post from people who have made it with frozen cauliflower and reported back that it worked well. Whichever you use, I would be sure the cauliflower is well-drained before you assemble the casserole.
What if you’re not a fan of Greek Yogurt?
If you don’t like the tangy flavor of Greek Yogurt I would use sour cream for this recipe.

How to Make Ham and Cauliflower Casserole au Gratin:
(This is ONLY a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)
- 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 ham.
- 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.
- 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.
Make it a Low-Carb Meal:
Ham and Cauliflower Casserole au Gratin would taste great with Peperoncini Chopped Salad, American Greek Salad, or Lemon Parmesan Kale Salad, Spring Mix Salad, or Kalyn’s Low-Carb Coleslaw for a low-carb meal.

This Low-Carb Ham and Cauliflower Casserole Au Gratin is definitely a treat for low-carb and Keto comfort food.
Ingredients
- 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)
Instructions
- 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.
- 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.
- 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.
- 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)
- 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.)
- 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.
- 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.
- I am assuming that this freezes well, but I still haven't tried freezing it because I never have any leftovers.
Notes
You can also use sour cream if you're not a Greek yogurt fan; yogurt has just slightly fewer carbs. Definitely use more cheese if you'd like!
