  • 1 Whole Spaghetti Squash, 3.25 lbs
  • 1/2 Tbsp  Olive Oil
  • 1/2 tsp Sea Salt
  • Black Pepper
  • 1 Lb Chicken Breast
  • 1/2 Cup Hot Sauce
  • 6 Tbsp Paleo-friendly Mayonnaise
  • 1/4 Cup Green Onion, sliced plus additional for topping
  • 1 Egg white


  • Preheat your oven to 400°F and line a baking sheet with tinfoil. Additionally, grease a casserole dish with a little bite of olive oil.
  • Cut the squash in half and scrape out the seeds. Rub the inside with the olive oil and sprinkle with salt and pepper.
  • Bake, cut-side down, until fork tender, about 30-40 minutes. Set aside to cool.
  • While the squash cools, bring a large pot of salted water to a boil. Once boiling, cook the chicken breast until no longer pink inside, about 15-20 minutes. Drain and set aside to cool.
  • Scrape the strands out of the cooled spaghetti squash and spread them out in one even layer on a piece of paper towel. Use another layer of paper towel to press out as much moisture as you can. Then, repeat with another paper towel.*
  • Once this is done, you should have about 3 lightly packed cups of spaghetti squash (or about 480g) Place into a large bowl.
  • Shred the chicken breasts (you should end up with about 3 packed cups of shredded chicken or 300g) and add it into the bowl with the squash.
  • Add all the remaining ingredients and stir until well combined.
  • Transfer into the prepared casserole dish, pressing out flat. Bake at 400 degrees, uncovered, until the edges are golden brown, and the top feels set, about 30 minutes.
  • Turn the oven to high broil and broil for 5 minutes. Then, let stand for 5 minutes to cool.
  • Garnish with extra onions and DEVOUR!
