1. Preheat your oven to 400 F (200 C). Carefully cut the spaghetti squash in half lengthwise. Scoop out the seeds and stringy bits from the center. Drizzle 1 tablespoon of olive oil over the cut sides of the squash, then season lightly with salt and pepper. Place the squash halves cut-side down on a baking sheet.

2. Bake the spaghetti squash for 35-45 minutes, or until the flesh is tender when pierced with a fork. The exact time will depend on the size of your squash. Once cooked, remove from the oven and let it cool slightly until it’s comfortable enough to handle.

3. While the squash is roasting, heat the remaining 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the cubed chicken and cook for 5-7 minutes, stirring occasionally, until browned and cooked through. Remove the chicken from the skillet and set aside.

4. In the same skillet, add the chopped onion and cook for 3-5 minutes until softened and translucent. Add the minced garlic and cook for another minute until fragrant. Stir in the broccoli florets, chicken broth, Italian seasoning, salt, and pepper. Bring to a simmer, then reduce heat, cover, and cook for 5-7 minutes, or until the broccoli is tender-crisp.

5. Return the cooked chicken to the skillet with the broccoli mixture. Stir everything together well to combine, ensuring the chicken is coated in the flavorful sauce.

6. Using a fork, gently scrape the cooked spaghetti squash flesh from the skin, creating noodle-like strands. Leave a small border of squash in the skin to maintain the “bowl” shape. Add about half of the spaghetti squash strands to the chicken and broccoli mixture in the skillet, stirring to combine.

7. Divide the chicken and broccoli spaghetti squash mixture evenly between the two spaghetti squash halves. You can mound it generously. Return the stuffed squash halves to the baking sheet.

8. Bake for an additional 10-15 minutes, or until the filling is heated through and slightly caramelized on top. Garnish with fresh chopped parsley, if desired, before serving.
