Ingredients & Variations

  • While cauliflower is the low carb star of this casserole and bacon has a delicious supporting role to play, why stop there? Feel free to add frozen mixed veggies, broccoli florets, chicken, turkey, even ground beef!
  • When adding other veggies, keep them low carb like peas, zucchini, and bell peppers. Carrots, potatoes, and squash are high in carbs and are not the best choices for keto recipes.
  • This recipe calls for fresh cauliflower, but frozen cauliflower rice works nicely if a food processor is not available. Another way to rice cauliflower is to grate it in its raw state with a box grater prior to cooking.
  • Pro tip! Let the cream cheese come to room temperature so it blends easier with the other ingredients.

How to Make Loaded Cauliflower Casserole

This casserole is as easy as 1, 2, 3!

  1. Combine cauliflower, cream cheese, sour cream, and salt and pepper (per recipe below).
  2. Place cauliflower mash into a casserole dish and stir in cheddar cheese, bacon, and green onions.
  3. Top with remaining cheddar and bake until the cheese is melted and bubbly.

This recipe makes the perfect low carb side alongside an Air Fryer Chicken Breasts or a tender Oven Roasted Pork Loin.

How To Prepare in Advance

Loaded Cauliflower Casserole can be made and assembled in advance so it’s ready to heat up and serve at a moment’s notice!

Cover the casserole tightly with plastic wrap and store it in the refrigerator for about a day. If the casserole is cool when you place in the oven, you may need to add on an additional 5-10 minutes to the bake time.

To Refrigerate – Loaded Cauliflower Casserole is one of those dishes that tastes even better the next day! Keep it covered in the refrigerator and it should last about 3 days.

To Freeze – You can either freeze cauliflower casserole before or after baking.

  • In either case, be sure to line the casserole dish with aluminum foil.
  • Remove the casserole from the casserole dish once frozen completely and wrap it in the foil. This way your casserole dish should be perfectly clean and ready for your next recipe!
  • Cover the foil-wrapped casserole in plastic wrap and don’t forget to write the date on the outside! Loaded Cauliflower Casserole should last about one month in the freezer.

To Reheat – Thaw the casserole in your refrigerator overnight or on your counter for about 3 hours. Bake in a 350˚F oven for about 30 minutes to warm through. If it was not baked prior to freezing, you may need to place under a broiler for an additional 5 minutes to give the cheese that nice golden brown color!

    Absolutely delicious! My husband who hates everything even loved the recipe. I felt like I was eating yummy potatoes. We added chopped up chicken to give it a little more hardiness I could eat this every night! I highly recommend this recipe. ❤️❤️❤️
