Ingredients
Main Ingredients
- 1 medium spaghetti squash
- 1 tsp avocado oil
- 1/2 tsp sea salt
- 1 lb chicken breast, cooked and shredded
- 1/4 cup dried chives
- 1 cup kefir ranch salad dressing
- 1/3 cup buffalo sauce
Instructions
- Preheat and prepare squash: Preheat your oven to 400 degrees F (204 degrees C). Slice the whole spaghetti squash in half lengthwise, remove the seeds and ribbing. Drizzle the cut sides with avocado oil and sprinkle with sea salt.

- Mix filling: Add the cooked shredded chicken, dried chives, kefir ranch dressing, and buffalo sauce to the bowl with the spaghetti squash. Mix thoroughly until all ingredients are well combined and evenly coated.
- Bake casserole: Transfer the mixture into a large baking or casserole dish. Bake at 400 degrees F for 15 minutes more to warm through and meld flavors.
- Serve: Serve hot with your choice of dippers. Optionally, top with blue cheese crumbles and an extra drizzle of ranch dressing for added flavor.
Notes
- If you prefer, substitute cooked shredded rotisserie chicken to save time.
- Adjust the amount of buffalo sauce to your preferred spice level.
- For a dairy-free option, substitute the kefir ranch with a dairy-free ranch dressing alternative.
- Blue cheese crumbles and extra ranch are optional but add great flavor contrast.
- Leftovers can be refrigerated for up to 3 days and reheated in the oven or microwave.
