  • 1 spaghetti squash cut in half length-wise, seeds removed

Fajita Chicken

  • 1 pound chicken raw, cut into 1-inch cubes
  • 1 t. cumin
  • 1 t. chili powder
  • ¼ t. onion powder
  • ¼ t. garlic powder
  • ¼ t. salt
  • ¼ t. pepper
  • 1/8 t. cayenne pepper
  • 3 T. olive oil
  • 2 T. lime juice


  • 2 bell peppers sliced into thin 2-inch long slices
  • 1 sweet onion sliced into thin 2-inch long slices
  • 2 cloves garlic crushed
  • 2-3 T. olive oil
  • ½ t. salt
  • ½ t. pepper


  • ¾ c. salsa + extra for topping
  • 1 ½ c. cheddar cheese divided into ¾ c. portions


  1. Preheat oven to 425 degrees.
  2. Drizzle 1 T. olive oil on each inside of the two spaghetti squash halves, with seeds removed. Sprinkle salt and pepper over each one and rub over the entire surface.
  3. Place squash halves on an aluminum foil lined baking sheet inside half facing down. Bake for 50 minutes.
  4. Combine all seasonings together in a small bowl and toss until well mixed. (If you do not have all of the seasonings on hand you can always use a Gluten Free Taco Seasoning packet instead).
  5. Add in 3 T. olive oil and lime juice and stir until combined.
  6. Place cubed chicken in a gallon Ziploc bag and add in marinade. Make sure to toss bag until all chicken is coated with marinade. Place in refrigerator until ready to use.
  7. When the spaghetti squash has about 25 minutes left of cooking, bring skillet with 2-3 T. oil (enough to coat the bottom) to medium heat and add in sliced bell peppers, onion, garlic and salt and pepper. Saute for about 16-18 minutes, stirring constantly until veggies are caramelized (you will start to see a golden brown forming on the onions.)
  8. When spaghetti squash has about 15 minutes left of cooking, bring another skillet (I used cast iron) to medium heat and add in chicken. Try not to add in too much of the marinade. Cook for about 10 minutes, or until chicken is cooked thoroughly. Drain liquid from chicken as you cook it.
  9. When chicken and veggies are cooked combine in the larger skillet with salsa and ¾ c. cheese. Mix until well combined.
  10. Once squash is done baking, remove from oven and place half of the fajita chicken mixture into each half. (It’s ok if not all of the filling mixture fits into the squash. I had to remove a little of my squash in order to make it all fit.)
  11. Top with remaining cheese. Bake at 425 for an additional 5 minutes, or until cheese begins to brown slightly.
  12. Serve with green onions and extra salsa, if desired. Enjoy!
