Yield Serves 4 people


  • 1 large spaghetti squash, about 5 cups cooked
  • 1 shallot, minced
  • 1 onion, minced
  • 2 garlic cloves, minced
  • 4 cups pumpkin or squash of choice, peeled and diced
  • 1-pound boneless skinless chicken breasts, cubed
  • 2 cups spinach
  • For the Sauce
  • 1/4 cup mayo, homemade or store bought
  • 2 tablespoons pumpkin puree
  • 2 tablespoons almond milk
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon sea salt, more to taste
  • 1/4 teaspoon garlic powder
  • 1/4 teaspoon black pepper
  • 1 tablespoon fresh thyme
  • Pinch of cinnamon
  • Topping
  • 1/3 cup fresh Parmesan cheese (optional)


  1. Wash and slice spaghetti squash in half, scoop out seeds. Place on baking sheet and roast spaghetti squash for about 30 to 40 minutes at 400-degree F. Remove from oven, allow to cool. Using a fork, scrape and fluff the strands from the sides of the squash. Set aside for later use.
  2. In a large skillet over medium heat, add 1 tablespoon olive oil, onion, shallots, and garlic. Cook for 1-2 minutes, or until onions become translucent. Add in cubed pumpkin or squash and cook until almost tender, about 8 minutes.
  3. Add in cubed chicken, salt, and pepper to taste. Continue cooking for about 8 minutes.
  4. Add in 2 cups of spinach and cook for 3-5 minutes or until spinach starts to wilt. Remove from heat and set aside.
  5. In a small bowl mix all sauce ingredients together and set aside. Grease an 8″ x 8″ (or similar sized) casserole dish.
  6. Add spaghetti squash to greased casserole dish. Layer in pumpkin and chicken mixture, and top with the sauce. Garnish with Parmesan, if desired.
  7. Bake at 400 degrees for 10 minutes, and broil for 3-5 minutes, or until the cheese is melted.
  8. Let cool for 10 minutes before serving.
