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 recipe! I have made it several times. Tonight we were out of sour cream, so I used plain nonfat organic Greek yogurt. It did not change the taste of the dish at all!

Literally one of the best things I have ever tasted. Anyone who tastes it asks for the recipe. And it’s even better as leftovers. Thanks for a great recipe!
That cauliflower casserole looks delicious, I just want to devour it off the screen! Thanks for sharing, Crissy!
Absolutely fantastic recipe! Great side dish with Steak!
I’m eating it as I type! This is delicious! Next time I’m going to dice up a jalapeno for it! Yummy!
I made this last night and it was amazingly delicious. I will make again. This mimics mac and cheese taste.
This was excellent! I made this as a side dish for flat iron steak. What an awesome meal. Will definitely make again. I did use 2 bags of frozen cauliflower to speed things up. Great recipe!
I make this all the time, I add one breast of shredded chicken and make it a main course. Sometimes I use different cheeses to change up flavor a little! Pepper jack cheese is wonderful! Love this, even our non-keto family does too!
Thank you. We love this and I wondered if frozen cauliflower would work!!! Glad to know you tried it this way and it worked. Now will make it even more!
Love this recipe I have made it several times excellent I find it best with fresh cauliflower.
