My family and friends are absolutely obsessed with it and request for me to make it all the time. If you love cheesy cauliflower, definitely give this low carb casserole recipe a try.

This keto-friendly cauliflower casserole is incredibly satisfying and makes such good leftovers. If you’re looking for a similar casserole and cauliflower isn’t your thing, also take a look at my Squash Casserole, Broccoli Casserole and Green Bean Casserole.

How to Make Loaded Twice Baked Keto Cauliflower Casserole

Making low carb twice baked keto cauliflower casseroles is one of my favorite ways to prepare a comforting, nutrient-dense dinner that the whole family will enjoy. Here’s one of my most highly requested recipes.

  • Preheat the oven while you prepare the cauliflower. Multi-tasking, am I right? Cut the cauliflower head into bite-sized florets and then place them into your baking dish. Drizzle with olive oil.
  • Bake. Season with salt and black pepper to taste and bake the cauliflower for 30 minutes.
  • Prepare the bacon crumble. While your cauliflower is baking, use a nonstick skillet to cook your bacon until it’s brown and crispy. Crumble and set aside.
  • Prepare the cheese mixture. Use a bowl to combine the cream cheese, sour cream, and shredded cheddar cheese. Don’t forget to season the cheese mixture with a bit of salt!
  • Add to cauliflower. Once the cauliflower is done, comes the fun part. Remove the baking dish and dollop the cheese mixture allll over top of the cauliflower. Sprinkle with remaining shredded cheddar cheese.
  • Bake. Return the dish to the oven and bake for an additional 5-7 minutes or until the cheese is melted and bubbly.
  • Serve. Sprinkle with crumbled bacon and sliced green onions before serving.

Tips for Getting the Perfect Cauliflower Texture

Here are a few quick tips to keep in mind to help improve your cauliflower texture when making this recipe:

  • Mash the cauliflower. Don’t be afraid to use a potato masher to give your cauliflower mixture a few quick mashes if you want a finer cauliflower casserole texture.
  • Try making with roasted cauliflower. You can make this recipe using raw cauliflower like this recipe calls for, but I actually find it can be even better when you make it with roasted cauliflower; I find that it adds a richer flavor to the twice baked casserole.

Keto-friendly Cauliflower Casserole Substitutes

If you would rather use different veggies to make yourself a low carb vegetable casserole, that’s definitely an option as well. Here are a few of my favorite veggies to use in my keto casseroles:

  • Can I Freeze Twice Baked Cauliflower Keto Casserole?

    You can definitely freeze this cauliflower casserole to reheat later on and enjoy as leftovers.

    If you plan on freezing it, I strongly recommend baking the keto cauliflower casserole in a dish that’s both oven-safe and freezer-safe. This makes it as easy as transferring the dish straight into the freezer; no fuss whatsoever.

    With that in mind, the first thing you’ll want to do is allow the casserole to cool off completely when it comes out of the oven. You’ll then be able to put the dish in the freezer, where the casserole will keep for up to 4-6 months.

    What’s the Best Way to Reheat Cauliflower Casserole?

    The best way to reheat cauliflower casserole is to simply put it straight in the oven from the freezer; don’t bother with thawing it out in the fridge overnight or anything like that.

    Simply preheat your oven to 400℉, remove the casserole dish from the freezer, and reheat it until it’s warmed through.

    1. Love this….
      I also added some shredded chicken, garlic and substituted green onion for cooked leek. Delish…

    2. Does the cauliflower casserole freeze well after it is cooked? It’s just me that I’m cooking for and would prefer to eat it maybe two times per week, but I don’t want to eat it every night! Thanks so much! I appreciate the recipes because I’m pretty new at this!
      Love and Blessings….Kathy

      • I believe this would freeze really well 🙂 Let me know if you try it though! Would love to know for how long it keeps in a freezer.
