  • Cook Time: 45
  • Total Time: 1 hour 5 minutes
  • Yield: Serves 6


  • 2 pounds chicken breast, cooked and shredded
  • 20 ounces frozen cauliflower rice
  • 2 small jalapeños, finely diced, plus more for topping if desired
  • 1 small white or yellow onion, diced
  • 1 red pepper, diced
  • 1/2 cup shredded or finely diced carrots
  • 1/2 cup canned coconut cream (the thick part at the top of the can)
  • 1/2 cup buffalo sauce
  • 1/4 cup ranch
  • 1 tablespoon minced garlic
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • Optional: green onion, extra jalapeños to garnish


  1. Preheat oven to 400 degrees F.
  2. Add vegetables and shredded chicken to a large casserole dish
  3. In a small bowl, combine spices, minced garlic, coconut cream, buffalo sauce and ranch. Whisk with a fork to combine well
  4. Pour into the casserole dish and use two forks or tongs to combine the sauce into the vegetables and chicken. Once the sauce is incorporated with the ingredients, smooth the ingredients into an even layer in the dish
  5. Place into the oven and bake for 45 minutes (or slightly longer if you want the top a bit more “crispy”)
  6. Remove from the oven and top with a drizzle of buffalo or ranch, and any optional garnish like green onion or more jalapeños


  • If you don’t already have cooked/leftover chicken to use, you can make the process of making this casserole faster by placing your chicken breasts on a sheet pan and baking for 25 minutes on 400 degrees F., and prepping the rest of the casserole while they bake. Chop the veggies, make the sauce and combine everything so you can just shred and add the chicken right when it’s done baking.
  • You can make your own homemade Whole30 ranch with this recipe
