How To Make Loaded Cauliflower Casserole

This recipe comes together super quick, but is also easily prepared ahead of time, making your life that much easier.


Cut the cauliflower into bite-size pieces then steam them for about 10 minutes until they are nice and fork tender. Drain any excess moisture from them by spreading the cooked cauliflower out on some paper towels.


Meanwhile, to a large bowl add the room temperature cream cheese, sour cream, bacon, green onions and seasonings. Stir until the mixture is creamy and combined.

Recipe Tips and Variations

My easy Loaded Cauliflower Casserole recipe is great if you’re looking for a tasty vegetable side dish option that’s low-carb and keto-friendly this holiday season, but also pleasing to all taste buds.

Here are a few recipe tips and variations you can use to make this recipe suit your needs…

  • Add in half broccoli and cauliflower to make it a lively and colorful dish.
  • Swap out the cauliflower for cooked, diced potatoes.
  • Use precooked crumbled bacon to save time prepping the recipe (I love the kind from Costco!).
  • If you prefer your cauliflower to have more bite to it, steam it a little less.

Can I Use Frozen Cauliflower?

Yes! You can swap out the fresh cauliflower for frozen cauliflower.

Most frozen cauliflower comes in a bag that is steam-able in the microwave. Just follow the instructions on the bag, steam until tender and then drain any excess water from the cauliflower.

*If there is too much water left on the cauliflower it can cause your casserole to be more soupy and less cheesy.

Make Ahead Cauliflower Casserole

This recipe is great for prepping a day ahead of time, making it a breeze to just pop it in the oven when you’re ready to bake.

Simply prepare the casserole dish up until the instructions call for baking. Cover and place the casserole in the fridge for up to 24 hours.

Prior to baking, remove the foil or plastic wrap and bake at 375 degrees for about 30 to 35 minutes.

PAY ATTENTION:  You’ll notice that I’ve reduced the heat and increased the bake time to allow the casserole to be heated through completely while not over baking the top. If you notice your cheese on top is getting too browned, simply cover loosely with foil and continue baking until the center is hot and bubbly.
