  • 1.5 lbs cooked chicken *diced or shredded
  • 5 cups riced cauliflower * from one large head
  • 1/2 cup buffalo sauce
  • 8 ounces cream cheese *at room temperature
  • 8 ounces sharp cheddar cheese *shredded from block


  • Preheat your oven to 375°F.
  • In a large bowl, combine the chicken, riced cauliflower, buffalo sauce, cream cheese, and half of the cheddar cheese.  The mixture will be thick.
  • Spread into a medium casserole dish and top with the remaining cheddar cheese.
  • Cover loosely with foil and bake for 25 minutes. Remove the foil and bake for an additional 10 minutes or until the cheese is melted and bubbling.
  • Garnish with extra Buffalo sauce and fresh, minced parsley, if desired. Serve hot.



Tips and Techniques for the Best Creamy Buffalo Chicken Cauliflower Casserole

  • Setting the cream cheese out to come to room temperature an hour before you begin will make it easier to combine all of the ingredients.
  • Cut the chicken into bite size cubes and cook in a skillet with olive oil until just done through, or use an Instant Pot, or use leftover or rotisserie chicken to save time.
  • It is best to shred the sharp cheddar cheese from a block rather than buying a bag of pre-shredded cheese which contains a starch and doesn't melt as well.
  • I recommend using fresh cauliflower, when possible. Using frozen may give you a runnier sauce.

How to Store Creamy Buffalo Chicken Cauliflower Casserole

  • You can store this casserole in the freezer, tightly covered and unbaked, for up to 6 months. Thaw in the refrigerator before baking. Increase the cook time to 35 minutes covered, then 10 minutes uncovered.
  • This casserole can be made ahead of time and kept in the refrigerator, tightly covered. It is recommended to bake it within 2 days. Increase the cook time to 35 minutes covered, then 10 minutes uncovered.
  • Store leftover Creamy Buffalo Chicken Cauliflower Casserole in an air-tight container in the refrigerator. Use within 3-4 days.
