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 this recipe, it is amazing and became our family’s favorite immediately!
Absolutely love this dish!!! Made it straight forward the first time (and even forgot the chives and it was to die for. I Spiced it up and added a rotisserie chicken this time, it’s in the oven and I can’t wait to dive in.
I’d like to use the frozen cauliflower already chopped (Costco). How many cups of that would be equivalent to a large head of cut up raw cauliflower?
Omg this was amazing!!!! My family loved it the only change I made was I added chicken
Was so good, even my picky son loves it.
Hi! I love love love this recipe? Have you ever tried freezing it? Thanks!
This might be one of the best dishes I’ve ever made! Thank you for the recipe!
I’m not a fan of mayo, or sour cream. Does this have those tastes or are they covered up by the rest of the ingredients? Not opposed to using them if I don’t have to taste them. Other than that, this looks amazing!
I’m not a fan of either as well, you can’t taste it! I add a pound of browned ground beef and make this a whole meal!
I made this tonight and it was amazing! I’ve shared the recipe two times already tonight:) thank you so much!!! I did add a little bit more ranch and I used a little broccoli also.
Love love love this recipe! We omit the bacon since we try to have less processed meats and it is still amazing. We also use a diy ranch seasoning because it’s easy to make organic and leave out the random crap they put in those packets :) We’ve had this multiple times for ourselves and the kids, and when entertaining. It’s always a hit!
I’ve tried it with a few times with both sour cream/Mayo and yogurt/Mayo. We are fans of the way the sour cream version turnaround out, better. Turns out less watery and tastier.
This was a hit in my home. It was really great!!!
