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.

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!

Love this casserole. I will keep making this for a dish to bring
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.
That would work great too!
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!
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!
Hi Crissy, Sounds delicious, and easy ! On Keto, so what about carbs and sugar counts as well as calories and fat? Thanks
If this is made with cauliflower pearls(rice)..would you still recommend steaming prior to assembling casserole? Can’t wait to try!!!
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
This casserole was the Star of Easter Lunch!!!
Requests have been made for it to be included on all of our family holiday menus.
Thanks!!
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 :)
My son made this recipe. It was amazing. Watch your cauliflower cooking time and add a bit more pepper. Excellent side dish!!
