This recipe has been one of my go-to family meals for years. It is so easy and delicious that even the pickiest eaters will love it.
What you'll need for this loaded cauliflower casserole:
I like to use Frozen Cauliflower Florets because it is so easy. But feel free to use fresh, steamed cauliflower. You can also sub broccoli for some or all of the cauliflower.
Sour Cream - you can use regular, low fat, fat-free, or vegan sour cream. In addition, feel free to sub plain greek yogurt as well.
Seasoned Salt, Pepper, and Onion Powder are my favorite seasonings to use in this recipe. I do sometimes add garlic powder or ranch dressing mix which are also great additions.
Cheddar Cheese is the classic choice, but feel free to swap it with any cheese that you like. Some of my favorite alternatives are pepper jack or gouda.
Bacon - Freshly cooked and crumbled bacon is best, but in a pinch feel free to use precooked bacon. You can also use turkey bacon to reduce the calories and fat.
Green Onions can be left out or swapped with chives.
Chicken Breast makes this dish a complete meal, but you can certainly make it without chicken for a delicious side dish!

Tips for making this casserole:
Be sure to cook the cauliflower before adding it to the casserole. I like to buy the steam in bag frozen cauliflower to cut down on prep time, but you can also use cooked fresh cauliflower as well.
After cooking the cauliflower I like to squeeze out some of the excess liquid. this prevents the casserole from becoming watery. To do this I transfer to cooked cauliflower into a strainer and gently press it with a flat spoon.
Be sure to just press gently - if you press too hard you will smash the florets which is not what we are going for here 🙂
The amount of salt needed in this recipe will vary based upon the salt content in the bacon that you use. I recommend salting to taste to ensure that the casserole doesn't turn out too bland or too salty.
Can this casserole be frozen?
Unfortunately, this casserole doesn't freeze well. It becomes a watery mess when it is thawed and so I DO NOT recommend it.
You can, however, assemble the casserole and store it in the fridge for up to two days before baking. If you are baking it this way, I suggest lowering the oven temp to 350 degrees F and baking for an additional 15-20 minutes.
How should I store leftovers?
After baking, this casserole can be stored in the fridge for up to a week. To reheat, cook in the microwave or oven until heated through.

Loaded Cauliflower Casserole with Chicken
Ingredients
- 24 oz Frozen Cauliflower Florets Cooked according to package instructions
- 1 ½ cup Sour Cream
- 1 teaspoon Seasoned Salt or to taste
- ½ teaspoon Pepper
- 1 teaspoon Onion Powder
- 2 cups Cheddar Cheese Shredded
- ½ lb Bacon Cooked and crumbled
- 2 Green Onons thinly sliced
- 1 lb Chicken Breast Cooked and shredded
Instructions
- Preheat the oven to 375° F and grease a 9x13" baking dish.
- *This step is optional but recomended* Place the cooked cauliflower in a strainer and gently press the cauliflower with a flat spoon or the palm of your hand (make sure the cauliflower isn't too hot) In order to remove some excess liquid. Be careful not to press too hard as you may smash the cauliflower.
- In a large bowl combine the sour cream, seasoned salt, pepper, onion powder, 1 ½ cups of the cheddar cheese, ½ of the cooked bacon, and ½ of the chopped green onion. Stir until well combined, then add the cauliflower and chicken. Gently stir to coat the chicken and cauliflower in the sour cream mixture.
- Transfer this mixture to the prepared baking dish and top with the remaining cheese and bacon.
- Bake for 30 minutes or until the casserole is hot and bubbly and the cheese is melted and slightly browned on top.
- Remove the casserole from the oven and top with the remaining green onion. Serve, and enjoy!

Very good. I didn’t have enough sour cream, so put in some cottage cheese that was recommended as a substitute. Family liked.

I put a layer of cooked Basmati rice in the bottom of my casserole dish first - did the rest as the recipe suggested except added smokey cheddar along with a pinch of smoked paprika and some cayenne pepper. Delicious to say the least. Tweaks never hurt anyone?
Dale Mason says
What leftovers? 😂 Seriously, it was really tasty. I forgot to salt my cauliflower. I added some cream cheese for creaminess. And chopped onion, which I could’ve sautéed in a little butter. Paprika on top. Great!!
