Prepping the spaghetti squash:

  • Preheat the oven to 400F.
  • Cut the spaghetti squash into quarters and remove the seeds with a spoon.
  • If you're having trouble cutting you spaghetti squash, you can poke holes in them and microwave until the are easier to cut. About 5-10 minutes.
  • Place the spaghetti squash, flesh side up, on a sheet pan and season generously with salt and pepper.
  • Bake in the 400F oven until the squash are fork tender.
  • This could take 30 minutes or more depending on the size of your spaghetti squash.

  • Add in the chicken breast and cook until the chicken is cooked through (about 8 more minutes)
  • Pour the chicken, pepper, and onion mixture into the bowl with the cooked spaghetti squash.

Making the mushroom sauce:

  • In the same skillet used to cook the chicken, sauté the minced mushrooms for about five minutes over medium heat.
  • Now whisk in the heavy cream, bullion cubes and the xanthan gum.
  • Bring to a boil to thicken.
  • Remove from the heat and set aside.
