Buffalo chicken is almost always a guaranteed win, and this easy-to-prepare Whole30 Buffalo Chicken Casserole is a lifesaver on busy weeknights. This flavorful and satisfying dish is perfect for anyone following the Whole30 program or anyone looking for a delicious gluten-free, dairy-free meal.

This casserole is made with cooked and shredded chicken breast, cauliflower rice, diced carrots and bell pepper, and shredded cabbage. These ingredients provide a balance of protein, vegetables, and satiating healthy fats. This makes for a well-rounded and nourishing meal.

To give the buffalo casserole a spicy kick, we use a Whole30-compatible buffalo hot sauce to adds bold, in-your-face flavor, tanginess, and depth.

To balance out the heat, we also used a compatible ranch dressing. Ranch adds a creamy element to the casserole, making it the perfect combination of spicy and cool.

Tips and tricks:

  • Grab a rotisserie chicken to save yourself from extra prep.
  • Make and bake a double-batch and pop one in the freezer for a rainy day!

Overall, this Whole30 Buffalo Chicken Casserole is a delicious choice for anyone participating in a Whole30 or simply looking to add a tasty and protein-packed meal that pleases the whole crowd. So why wait? Try it out today!
