Chicken cauliflower casserole

Twelve months ago I wrote a post about a recipe called cauliflower gratin.  It’s been almost a year since that post and I have decided to bring it back except in casserole form.  My family loves casseroles because of the ease of most of them and because you have days of leftovers.  That means no cooking and more time to do other stuff around the house.   Not to mention you save money.  I’m all for saving money these days especially with it being Christmas time.

Now I am a HUGE fan of cauliflower and so is my daughter.  We usually roast it in the oven with a little bit of olive oil.  I was a little hesitant to see if Livi would take to this recipe but she loves all the ingredients in this dish.  I can officially say that she finished off TWO helpings all by herself.  I was a proud mama and will be making it again.


The two cheeses that I used for this dish was a gruyere cheese and the other was a Kraft Mild Cheddar Cheese.  I’ve paired these two together before, so I knew that they would work perfect with the cauliflower, chicken, spinach and mushrooms.

This is a great casserole dish for the family and a great way to get your kids to eat their vegetables.

  1. This looks really good. I think I might try it. I’m pretty much addicted to cauliflower these days, only I tend to just cook it up and sprinkle some parmesan on it, so this looks like more work but more of a meal than a side.

  2. Made this for dinner tonight and it was amazing! I spread the cooked cauliflower in the bottom of the baking dish and then spread the chicken and cheese mixture over the top of it. It worked great!

  3. I currently have this baking in the oven & it smells delicious. I also added chopped zucchini & red onions as well as the vegetables listed.

  4. Sounds awesome but I wonder about the nutrition information?

    • Hi Dawn,

      Unfortunately I don’t do the nutritional facts for my recipes. I know that there are several sites that allow you to plug in the ingredients to get that info.

  5. The printing did not come out good. It is all blurry. Is there something you can do to fix it.

  6. I will be making this as per the recipe but tonight I was looking for something to use with what I had and it was great! Very versatile recipe so that’s a keeper for me. I had Monterey Jack and Gouda for cheese, 3 frozen spinach balls, 1 c frozen peas instead of mushrooms and leftover turkey for the chicken. Thanks you for adding to my recipe box 🙂

  7. Wow! What a surprise! I must clarify…I’m always spending weekends making casseroles to put away in the freezer for us to eat on those nights when I don’t have time to cook. I had labeled this correctly, “Cauliflower Chicken Casserole”. But I always make the “Loaded Baked Potato” casserole, and use faux mashed potatoes, topped with chicken, so that’s what I thought it was when I pulled it from the freezer. Upon baking and uncovering, I wondered, what? This has something green, that looks likes spinach. Well, we ate it, and fell in love with it! So I went to my Pinterest page and found that I had pinned it, and made it, and stuffed the poor casserole in the freezer for about 9 months. Needless to say, while we ate it, I was calling it “mystery casserole”…no more, now that I know what this is. Making again!
