How To Make Buffalo Chicken Casserole
- Saute the veggies: Heat the oil in a large skillet over medium-high heat. Saute the onion and celery until soft, 2-3 minutes. Mix in the cauliflower rice or regular cooked rice.
- Transfer to a casserole dish: Dump it all into a greased casserole dish with cooked chicken, ranch dressing, hot sauce, cream cheese, and cheddar cheese. Stir to combine so the cream cheese starts to melt. Sprinkle more shredded cheese on top.
- Bake: Bake at 400°F for 25-30 minutes, until the cheese is melted, bubbling, and golden brown. Top it with a drizzle of ranch, green onions, and bleu cheese.

Recipe Variations
- Adjust the heat. One of the best things about this buffalo chicken casserole is the kick of heat. Whether you’re like me and prefer just enough hot sauce to give the dish some kick, or like my husband who loves anything spicy, simply adjust the amount of buffalo sauce to your desired taste!
- Use leftovers. I love to use leftover chicken or rotisserie chicken for this recipe. If you don’t have cooked chicken on hand, bake chicken breasts at 425°F until the internal temperature reaches 160°F, 17-21 minutes depending on the size of the chicken breast. You can also use leftover cooked rice, make fresh stovetop rice, or use minute rice.
Storing Leftovers
Allow the casserole to come to room temperature, then cover it in plastic wrap or store it in an airtight container for up to 3 days.
This buffalo chicken casserole freezes really well if you have leftovers or want to freeze extra for another weeknight. Transfer the entire casserole to a freezer-safe container or individual meal prep containers and place in the freezer. They store well for 3 months!

Love this! One small edit, the recipe calls for garlic powder and salt but the are not mentioned in the instructions.
Thanks for calling that out, Judith! I updated the recipe!
The chicken broth is not listed in the ingredients – what is the measurement for that item?
Hey Jody! Thanks for calling that out. I tested this originally with some broth and ended up not using it in the final recipe. Forgot to remove it from the directions! It’s updated:)
Awesome recipe! I cooked my chicken in the crockpot with some broth and hot sauce. Left my celery a bit crunchy which added a nice crunch to this casserole. Also used the cauliflower rice. Yum! On a side note, the recipe list says one small ranch dressing. Not sure you meant to have that there. It’s at the top of the list. Anyway, new easy favorite of ours!!!
Thanks, Dawn! And thanks for catching that typo. I removed it:)
