Ingredients to Make Creamy Buffalo Chicken Casserole
Here are all the ingredients to gather to make this buffalo chicken casserole right away:
- Chicken breast – you’ll need pre-cooked chicken that has been shredded or chopped. To cook the chicken and keep it tender and juicy, we recommend our no-fail stovetop recipe for perfect chicken breasts or Instant Pot Shredded Chicken
- Oil – we recommend extra-virgin olive oil or avocado oil because they are less processed and a neutral flavor
- Fresh vegetables – a combination of cauliflower rice, carrots, red bell pepper, and yellow onion forms the base of the casserole adding texture and nutrients
- Herbs and spices – you’ll need garlic powder, dried parsley, salt, and black pepper
- Buffalo sauce – use your favorite purchased buffalo sauce (we love the Primal Kitchen No-Dairy Buffalo Sauce). Or, make your own using our easy Homemade Buffalo Sauce recipe
- Mayo – this is what creates the creamy consistency. Use your favorite dairy-free mayo (ours is Primal Kitchen Mayo, which is made with avocado oil)
- Eggs – an excellent source of protein and healthy fats, this helps create a richer flavor and acts as a binder to hold the casserole together
- Toppings – we love to add even more flavor by topping this creamy buffalo chicken casserole off with a drizzle of ranch dressing (try our Homemade Ranch), hot sauce, or additional buffalo sauce, and a sprinkle of green onions
Ingredient Spotlight: Chicken
One of the most versatile protein sources available, we use chicken in a wide variety of recipes like those included in this 14 sheet pan chicken recipes post. Not only is it budget-friendly and delicious, but chicken is also:
- An excellent source of complete protein
- Rich in B vitamins
- A good source of some minerals such as zinc, iron, and copper

Our Favorite Meal-Prep Containers
These are our favorite meal-prep containers that we’ve been using for many years to pack away lunches and dinners that are ready to go. We love the airtight glass storage that is freezer-, microwave-, and dishwasher-safe and has lock-in-place lids. They sell out often, so snag an 8-pack set for yourself when they’re available!
