Our loaded cauliflower casserole is bursting with flavor. This casserole takes cauliflower to a whole new level thanks to yummy ingredients like sour cream, lots of cheese, and crispy bacon.

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!

Very tasty and flavorful. Made it for a potluck and brought home an empty casserole dish! Will definitely make again.
Ewe just made this for dinner as is. It is delicious and just bursting with the flavor of a loaded baked potato! Thank you for the recipes. Even the kids enjoyed it! Will definitely be putting this into the rotation. I can’t wait to experiment with other add ins!!!
Hi! I am already loving the recipe just by reading it. Can i use mucrowave instead of oven though?
This is the second time I’m making this in two weeks. Second time I left out the bacon. I also used light mayo and sour cream. 180 calories per serving and delicious!!!!! (Even with no bacon)
Can this be made using cauliflower in Steamfresh packs out of the frozen food section, in order to save on time?
This was absolutely delicious. My husband really enjoyed it too!!! I’m trying out the keto diet and this will be on the menu.
Made this tonight and oh my word!!! I’m a girl who loves her loaded bake potatoes or potato soup and this right here nailed it for this keto girl! I added sautéed mushrooms, onions, spinach, and green bell pepper to have even more veggies – so rich and filling! I think next time I might even add in some chopped chicken. Thanks for this recipe!
This dish is fantastic! My husband likes when I add broccoli to it (but honestly I prefer the recipe just as it is!). I have made it AT LEAST 4 times now. It’s great as a meal all itself!
Do yourself a favor, double the recipe!
So glad you love it, Jennifer! Good idea about adding some broccoli!
Just made this tonight and it was so good! I made it for a main dish and used two heads of cauliflower and used a whole package of turkey bacon and added chicken. Yay for leftovers!!
I love the casserole. I added 1tbs of margarine. And served as a side to Mild sausages with green peppers and red onions. Adding it to my new side dishes. Thank you!
This dish is absolutely delicious!! I will definitely be making it over and over again.
