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!

Thank you for posting this. Do you know how much is in a serving?
It says 3/4 cup is a serving. I am wondering how many ounces is in a serving. :) I calculate by ounces normally.
This looks frickin delightful! Is the ranch seasoning a make or break with this recipe? I’m only asking cause I’ve used the seasoning in otherrecipes and it’s just ruined it for me.
Omg…sooooooo good! It’s a keeper for my Keto lifestyle. Thank you.
My family loves this recipe, even the twins who are 21/2!
Hi, how much protein, carbs, fat etc in each serving. Thank you
This. looks. AMAZING! I LOVE loaded potatoes, but am trying to eat more low carb so this is perfect! And you can’t go wrong with casseroles! Thanks for sharing!!!
I made this once back in June and holy man it was sooooooo good!
I added half a brick of cream cheese and it made it that much more cheesy and delicious. I’m planning on bringing it to a potluck dinner in a crockpot. Wondering if you would recommend using uncooked cauliflower instead of steamed as it will be cooking on low for a few hours???
Thanks!!
What other cheese would be good, as I don’t have Colby or Monterey Jack?
Any cheddar would be amazing!
I’m currently following the keto way of eating. I want to enter all the ingredients into the carb manager app in order to track my intake. How many servings in this casserole?
Hi Chrissy, I would say there are 8 servings in this.
I made this casserole to take to a family gathering, and everyone loved it now I make it all the time.
