Loaded Cauliflower Casserole

I’m a believer in the casserole as a dinner solution for busy families, and this loaded cauliflower casserole might just be one of my favorite easy casserole recipes.

This loaded cauliflower casserole is bursting with flavor—all the RIGHT flavors—that is. This casserole takes cauliflower to a whole new level thanks to yummy ingredients like sour cream, lots of cheese and bacon.

While this isn’t exactly a light (okay, it’s not light AT ALL) recipe, but hey, at least you’re replacing the potatoes or pasta that might have taken up the bulk of a similar casserole recipe with a low-carb vegetable. Three cheers for vegetables!

Even my kids who aren’t typically huge fans of cauliflower love this cheesy and delicious loaded cauliflower casserole recipe.

Come to think of it, and the thought literally just popped into my head, if you wanted to add some more nutrition here you could use half cauliflower and half broccoli in this dish.

Whether this loaded cauliflower casserole is a main dish or a side dish is up for debate.

For me, personally, I could easily make a warm bowl of this casserole my entire dinner, but you can serve it alongside your favorite meat and a garden salad.

If you wanted to beef-up the casserole (err… chicken-it-up?) you could shred some rotisserie chicken and add it to the dish prior to baking.

When I was a kid my mom would always steam a pan of cauliflower and then sprinkle a bunch of cheddar cheese on top. She and I would eat a huge plate of that stuff and it’s what made me grow to love cauliflower when I was younger.

This loaded cauliflower casserole recipe reminds me of the cheesy plates of cauliflower that my mom would whip-up, but WAY BETTER.

The crispy bacon in this cauliflower casserole really sends it over the top. It adds a nice crunch that pairs nicely with the creamy steamed cauliflower and cheese.

  1. This. looks. AMAZING! I LOVE loaded potatoes, but am trying to eat more low carb so this is perfect! And you can’t go wrong with casseroles! Thanks for sharing!!!

  2. I made this once back in June and holy man it was sooooooo good!I added half a brick of cream cheese and it made it that much more cheesy and delicious. I’m planning on bringing it to a potluck dinner in a crockpot. Wondering if you would recommend using uncooked cauliflower instead of steamed as it will be cooking on low for a few hours???Thanks!!

  3. What other cheese would be good, as I don’t have Colby or Monterey Jack?

  4. I’m currently following the keto way of eating. I want to enter all the ingredients into the carb manager app in order to track my intake. How many servings in this casserole? 

  5. I made this casserole to take to a family gathering, and everyone loved it now I make it all the time.

  6. Love this casserole. I will keep making this for a dish to bring

  7. This recipe sounds amazing and I can’t wait to try it. I was wondering if it could be made with roasted cauliflower instead of steamed? I just adore the extra flavor that roasting creates with veggies.

  8. Made this tonight and loved it! Even my kids liked it and one of them is super picky! I love that it was low carb (well, no pasta, grains, potatoes, at least) for me without having to make a bunch of adjustments or something extra for myself. I’ve made stuff with ranch seasoning before and usually find it overwhelming or weird warmed up but this was just perfect. Added the shredded rotisserie chicken and it was perfect. I will serve it with green beans and crescent rolls (for the non-diabetics) next time!

    • Hi Beth! I’m so glad you loved it. Thank you for commenting and letting the other readers know that it was great with rotisserie chicken. I haven’t tried that yet but it’s on my list!

  9. I added the crispy fried onions on top. Aldi carries a gluten free brand. This recipe is so easy and delicious! My husband, who is struggling with the loss of his carbs had seconds! I’m definitely using this as a go to side dish! My sister-in-law will love this!

  10. Hi Crissy, Sounds delicious, and easy ! On Keto, so what about carbs and sugar counts as well as calories and fat? Thanks

  11. If this is made with cauliflower pearls(rice)..would you still recommend steaming prior to assembling casserole? Can’t wait to try!!!

  12. I made this the first time on Easter Sunday. It was devoured. My husband told me to add this to the rotation of sides for supper. I’ve already shared the recipe, twice! It’s a huge hit. Thank you

  14. This recipe was amazing. Quite a process but eventually it will become easier to put together as I will be making this casserole often. My love and my brother were both blown away when they tasted it! I am quite a chef for the most part but this one really wowed them. Thank you so much for sharing this as I can now share this food of love with others :)

  24. I know someone else had asked this question but I didn’t see an answer. Can you make ahead, refrigerate and then bake? Also, how many people do you think this will feed as a side dish for Christmas?

  25. If I’m making this the night before and putting it in the fridge, at what temperature and for how long should I bake it the following day?

  26. Hi Crissy, Just curious to know if you have the nutritional values/content for the cauliflowercasserole. Thanks,Andrea

  27. My family loved this! Nice option instead of potatoes. We’ll be having this again. Thank you!!

  28. Do you have the nutrional info for this recipe? 

  29. Can I omit the sour cream?

  30. Wow! This is fabulous!

  31. So good! I made this for myself and my wife while she was on the way home from work. So by the time she got in the door, I was just adding grilled chicken breast cut into bite size pieces, and mixed into the general mix, and sliding it into the oven. My only comment, is she liked it well enough to compliment me for it. It is printed out and it will be a repeat in this house. And she commented about the Ranch seasoning. It made a difference, and one she picked up on. I hadn’t told her it was in the list of ingredients.

  32. Hi!  Just letting you know I have featured this recipe in my post roundup of 14 delicious recipes using cauliflower! https://jenniferbanz.com/14-delicious-low-carb-recipes-using-cauliflower

  33. can the cauliflower casserole be made ahead of time and refrigerated until ready to bake?

  34. I want to try the tater tot casserole.

  35. Exactly like my recipe from 3 years ago minus the ranch seasoning… will have to try that.
