Ingredients You’ll Need
For the Spaghetti Squash:
- 1 large spaghetti squash, halved and seeds removed
- 1-2 tablespoons olive oil
- Salt & pepper to taste
For the Creamy Garlic Parmesan Chicken Filling:
- 1 pound boneless, skinless chicken breast or thighs, diced
- 1 tablespoon olive oil
- 2 tablespoons butter
- 4 cloves garlic, minced
- 2 cups baby spinach (fresh or frozen, squeezed dry)
- 1 cup heavy cream or half-and-half
- 1 cup grated Parmesan cheese
- 1 teaspoon Italian seasoning
- Salt & pepper to taste
- Optional: A pinch of crushed red pepper flakes for heat
For Topping:
- 1/2 cup mozzarella cheese (optional, for extra cheesiness)
- Fresh parsley or basil for garnish
Step-by-Step Instructions
1. Roast the Spaghetti Squash
- Preheat your oven to 400°F (200°C).
- Cut the spaghetti squash in half lengthwise and scoop out the seeds.
- Drizzle the cut sides with olive oil, then season with salt and pepper.
- Place cut-side down on a baking sheet lined with parchment paper.
- Roast for 35-40 minutes, or until the flesh is tender and easily pulls away into strands with a fork.
- Once cool enough to handle, use a fork to gently scrape the squash strands but keep them in the shell to create the “boats.”
2. Prepare the Chicken and Creamy Garlic Parmesan Sauce
- In a large skillet over medium heat, add olive oil and diced chicken. Season with salt, pepper, and half of the Italian seasoning. Cook until chicken is golden and cooked through (about 5-7 minutes). Remove chicken and set aside.
- In the same pan, melt butter and sauté minced garlic until fragrant (about 1 minute).
- Add the heavy cream and bring to a gentle simmer. Stir in Parmesan cheese, remaining Italian seasoning, and optional red pepper flakes.
- Add baby spinach to the sauce and stir until wilted.
- Return the cooked chicken to the pan and toss to coat everything in the creamy garlic parmesan sauce. Taste and adjust seasoning.
3. Assemble the Stuffed Squash
- Set the roasted spaghetti squash halves on a baking tray.
- Divide the creamy chicken and spinach mixture evenly between the two squash boats, stirring gently to combine with the squash strands.
- Sprinkle mozzarella cheese over the top for extra gooey goodness.
4. Bake to Perfection
- Return the filled squash to the oven and bake for an additional 10-12 minutes, or until bubbly and golden on top.
- Garnish with fresh parsley or basil before serving.
Serving Ideas
This Garlic Parmesan Stuffed Spaghetti Squash is hearty enough to stand alone, but you can serve it alongside:
- A crisp side salad with lemon vinaigrette
- Steamed or roasted veggies for extra nutrition
- Garlic bread (for non-low-carb eaters)
For a touch of acidity, a squeeze of fresh lemon over the finished dish brightens the creamy sauce beautifully.
Tips for Success
- Don’t overcook the squash: It should be tender but not mushy to hold the filling well.
- Use rotisserie chicken: For a time-saving shortcut, use pre-cooked shredded chicken.
- Experiment with cheese: Add Gruyère, Fontina, or Asiago for different flavor profiles.
- Make it vegetarian: Skip the chicken and add sautéed mushrooms or more greens.
- Meal prep friendly: Store leftovers in an airtight container for up to 4 days. Reheat in the oven for best texture.
