Key Ingredients for this Buffalo Chicken Casserole (plus substitution ideas)

These are the key ingredients for making this buffalo chicken casserole taste amazing (plus substitution ideas).

  • Primal Kitchen Buffalo Sauce: This is my absolute favorite brand of buffalo sauce to use in this casserole. Not only because it tastes amazing, but also because it’s full of healthy ingredients with zero artificial ingredients. But, technically, any buffalo sauce will work!
  • Plain Coconut or Greek Yogurt: To add to the creaminess of this buffalo chicken casserole, I like to include yogurt as well. Personally, I like to use plain coconut yogurt to keep this casserole dairy free, but feel free to use plain greek yogurt as well… just make sure the yogurt is PLAIN (no flavors or sugars added).
  • Spaghetti Squash: Of course, one of the main ingredients in this casserole is the spaghetti squash. You’ll need 1 large squash or 2 small-medium in order to yield 4 cups worth. Substitution Ideas: If you’re not a fan of spaghetti squash, try substituting it with cauliflower rice or thin zucchini noodles.

What to Serve With this Buffalo Chicken Casserole

I usually serve this buffalo chicken casserole with a side of steamed broccoli and fresh avocado. But, here are some other healthy side options…

Tips for the Best Buffalo Chicken Casserole

  • Make sure you roast the spaghetti squash long enough to ensure that the spaghetti-like strands are extra soft and not crunchy. You’ll know you’ve cooked the squash long enough when you can easily pierce the flesh with a fork.
  • For the best shredded chicken that’s super moist, I like to use my pressure cooker.
  • Whether you use coconut or greek yogurt, make sure it’s plain with no added flavors or sugars.

This buffalo chicken casserole is the perfect healthy dinner recipe. It’s gluten free, grain free, and dairy free.

Ingredients

  • 4 C. Spaghetti Squash Strands (1 large squash or 2 small/medium)

  • 1 lb Chicken Breasts, cooked & shredded

  • 1 C. Chicken Broth

  • 1/2 heaping C. Yellow Onion, chopped

  • 1/2 heaping C. Bell Pepper, de-seeded & chopped (any color)

  • 1/2 C. Celery, chopped

  • 1 Egg

  • 1.5 tsp Avocado Oil

  • 1/2 C. Primal Kitchen Buffalo Sauce (KAYLA10 for 10% Off) or any buffalo sauce

  • 1/4 C. Plain Coconut or Greek Yogurt

  • 1/2 tsp EACH of Garlic Powder & Onion Powder

  • 1/4 tsp EACH of Sea Salt & Pepper

Directions

  • Preheat oven to 400 F. Line a baking sheet with parchment paper. Set aside.
  • For the spaghetti squash, cut it in half length-wise. Scoop out the seeds & stringy flesh in the center. Spray with avocado oil, lightly season with sea salt, and pepper. Place the squash cut-side down onto the lined baking sheet. Bake for 40-50 minutes or until you can easily pierce the flesh with a fork. Once done, let it cool down a bit. Then, using a fork, scrape out the spaghetti-like strands. You’ll need 4 C. worth.
  • For the chicken, I used my pressure cooker but you can also bake them. For the pressure cooker: add the chicken broth to the pot along with the chicken breasts (lightly season them with sea salt & pepper). Place the valve to the sealed position and pressure cook on high for 14 minutes. Once done, do a quick release. For baking: add the chicken breasts & broth to a baking dish and bake at 400 F. for 20-25 minutes or until done. Once chicken is done, shred it with a fork.
  • In a skillet over medium heat, add the chopped onion, bell pepper, and celery along with a splash of water. Cover skillet with a lid and cook until they’re slightly soft & water has evaporated. Remove from skillet & set aside.
  • In a mixing bowl, add the spaghetti squash strands, sauteed vegetables, and shredded chicken.
  • In a separate mixing bowl, add the egg, oil, buffalo sauce, yogurt, garlic powder, onion powder, sea salt, and pepper. Whisk until fully combined.
  • Pour the buffalo sauce mixture over the chicken squash mixture. Mix until fully combined.
  • Grease a 9×13 baking dish. Pour the mixture into the dish and spread it out as evenly as possible. Bake at 400 F. for about 30-35 minutes. Then, broil it for 5-10 minutes to give the top a golden color. Once done, remove from oven and add fresh chives & drizzle yogurt or sour cream over top (optional). Cut into 10 roughly equal squares. 2 squares = 1 serving
