Ingredients

Scale

Spaghetti Squash

  • 1 large spaghetti squash
  • 3 tablespoons olive oil (divided)
  • 1 teaspoon salt (divided)
  • 1/2 teaspoon freshly grated black pepper (divided)

Chicken and Broccoli Filling

  • 2 large chicken breasts, chopped into bite-size pieces
  • 2 shallots, minced
  • 6 cloves garlic, minced
  • 2 teaspoons Italian seasoning
  • 3 cups broccoli florets
  • 4 tablespoons cream cheese (at room temperature)
  • 1/2 cup plain Greek yogurt
  • 1/2 cup Parmesan cheese, shredded
  • 1.5 cups mozzarella cheese, shredded (divided)

Instructions

  1. Cook Spaghetti Squash: Preheat your oven to 400°F (204°C) and line a large baking sheet with parchment paper. Scrub the spaghetti squash clean and dry thoroughly. Using a sharp, stable knife, carefully cut the squash lengthwise (stem to end) and scoop out the seeds. Drizzle both halves with 2 tablespoons of olive oil and brush evenly over the surface. Sprinkle with half the salt and pepper, then place the squash cut-side down on the prepared baking sheet. Bake for 45 minutes to 1 hour, or until the squash is tender and easily pierced with a fork. Let cool slightly, then use a fork to scrape out the flesh into long strands, setting aside in a large mixing bowl.
  2. Prepare Chicken and Broccoli: Lower the oven temperature to 350°F (177°C). Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the chopped chicken breasts, seasoning with salt and pepper, and cook for 5-6 minutes, stirring often, until fully cooked and lightly browned. Remove chicken from the skillet and set aside. In the same skillet, add the remaining tablespoon of olive oil and the minced shallots. Sauté for 2-3 minutes until soft and translucent. Add the garlic, remaining salt and pepper, and Italian seasoning; cook for about 30 seconds until fragrant. Add the broccoli florets along with 1-2 tablespoons of water, mix well, cover, and steam for 2 minutes. Return the cooked chicken to the skillet, stir to combine, and cook for 1-2 more minutes. Remove from heat.
  3. Combine Filling Mixture: In the large mixing bowl with the spaghetti squash strands, add the cream cheese and Greek yogurt. Stir until smooth. Add the cooked chicken and broccoli mixture to the bowl and mix well to combine. Stir in the Parmesan cheese and half of the shredded mozzarella cheese.
  4. Stuff and Bake: Divide the spaghetti squash and chicken mixture evenly back into the spaghetti squash shells or into individual baking dishes. Top each with the remaining mozzarella cheese. Place the stuffed squash face up on the lined baking sheet. Cover loosely with foil, creating a tent to keep the foil from touching the cheese, and bake at 350°F (177°C) for 15 minutes. Then remove the foil and bake an additional 5-10 minutes, or until the cheese is golden and bubbly.
  5. Garnish and Serve: Remove from the oven and garnish with fresh chopped parsley or red pepper flakes, if desired. Serve warm and enjoy your hearty, cheesy stuffed spaghetti squash!

Notes

  • Use a very sharp, stable knife to cut the spaghetti squash safely as it can be tough to cut through.
  • You can substitute broccoli with other veggies like asparagus or kale if preferred.
  • To make it spicier, add red pepper flakes to the cheese mixture or sprinkle on top before baking.
  • Make sure cream cheese is at room temperature to blend smoothly into the Greek yogurt.
  • Leftovers keep well refrigerated in an airtight container for up to 3 days and reheat nicely in the oven or microwave.
