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!

This was delicious! Next time I will double the sauce ingredients since I found it a little dry. I didn’t have fresh cauliflower so used two bags of frozen. Next time I will double the recipe so there will be leftovers. Thanks for a new and exciting way to consume more veggies!
So delicious! My hubby’s fav keto dish!
Can this be made ahead & frozen?
How long would this last if I were to make it to take in my lunches for the week? Trying to eat low carb and this looks amazing, going to add chicken for the extra protein. Thanks
This is sinfully delicious! Made a great side dish with our steaks. Thank you for sharing
Amazing! The hubby loved it.
We are traveling for Thanksgiving, and I must bring my own low-carb dishes if I plan to stay on keto. Could I make this in advance and freeze it? Thanks.
Do you mean one cup each of Colby And Monterrey jack ? Two cups total? Or one cup total? Thank you, can’t wait to make it!
Colby & Monterey Jack is a type of cheese. It’s just 1 cup of it.
I believe the recipe calls for 1 cup total of the colby/monterey jack blended style cheese sold in stores, not 1 cup of each. I’m also looking forward to trying this. Sounds and looks delicious!
I thought this looked delicious and was planning to make it at home. My kids’ school had P/T conferences, so I made a pan and took it to school for the teachers to have for supper. They loved it! I can’t wait to make it for me to eat!.
This was amazing! Will make again! I like everyone’s comments and how they added differ t ingredients. Might try it with some other goodies next time :)
