Loaded Cauliflower Casserole Recipe
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.
Old-fashioned casseroles are usually loaded with pasta or rice, but I’m loving this casserole because the main star of the dish is healthy cauliflower. 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.

Easy Keto Cauliflower Casserole
This is a wonderful casserole for anyone doing the keto diet. With just 3 carbs per serving, it’s a satisfying dinner that will help keep you on track with your goals.
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.

This loaded cauliflower casserole recipe is definitely worth giving a try. Be sure to add it to your weekly meal plan this week and let me know how you like it!

Hi Crissy,
Just curious to know if you have the nutritional values/content for the cauliflower
casserole. Thanks,
Andrea
My family loved this! Nice option instead of potatoes. We’ll be having this again. Thank you!!
Do you have the nutrional info for this recipe?
I’m sorry Claudia, I don’t. I’m working on including that information in the future.
Can I omit the sour cream?
Hi Amanda, you’re going to lose a lot of moisture by doing that, so I’m not sure that I would recommend it.
Wow! This is fabulous!
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.
Hi Gene, thanks for commenting! I’m so glad that you and your wife liked this recipe. Adding chicken is a great idea! :)
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
can the cauliflower casserole be made ahead of time and refrigerated until ready to bake?
I’m wondering the same thing!!
I want to try the tater tot casserole.
Exactly like my recipe from 3 years ago minus the ranch seasoning… will have to try that.
