Ingredients Method

Ingredients

  

• 1 medium spaghetti squash (about 2.5–3 pounds)
• 2 tablespoons olive oil, divided (plus more for drizzling)
• 1 pound boneless, skinless chicken thighs or breasts, cut into bite-size pieces
• 1 teaspoon kosher salt, divided (plus more to taste)
• 1/2 teaspoon black pepper
• 1 teaspoon Italian seasoning or dried oregano
• 3 cloves garlic, minced
• 1/2 cup oil-packed sun-dried tomatoes, drained and sliced (reserve 1 tablespoon oil if you like)
• 1/2 cup low-sodium chicken broth
• 3/4 cup heavy cream (or 2/3 cup half-and-half for lighter)
• 1/2 cup freshly grated Parmesan cheese, plus more for serving
• 1 teaspoon lemon zest and 1 tablespoon lemon juice
• 1/4 teaspoon crushed red pepper flakes (optional)
• 1 cup baby spinach or chopped kale
• Fresh basil, chopped (about 1/4 cup)

Method

 

1. Roast the spaghetti squash. Preheat the oven to 400°F (200°C). Halve the squash lengthwise and scoop out the seeds. Drizzle the cut sides with olive oil, season with a pinch of salt and pepper, and place cut side down on a parchment-lined baking sheet. Roast for 35–45 minutes, until the strands pull apart easily with a fork and the edges are lightly caramelized.
2. Shred the squash. When cool enough to handle, use a fork to scrape the flesh into long “spaghetti” strands. Toss with a little olive oil and a pinch of salt to keep it from drying out. Set aside.
3. Season and sear the chicken. Pat the chicken dry. Season with 1/2 teaspoon salt, pepper, and Italian seasoning. Heat 1 tablespoon olive oil (or the reserved sun-dried tomato oil for extra flavor) in a large skillet over medium-high heat. Sear the chicken in a single layer until golden and cooked through, about 5–7 minutes. Transfer to a plate.
4. Sauté aromatics. In the same skillet, reduce heat to medium and add the remaining 1 tablespoon oil if needed. Add garlic and sun-dried tomatoes. Cook for 30–60 seconds until fragrant, stirring so the garlic doesn’t brown.
5. Build the sauce. Pour in the chicken broth to deglaze, scraping up any browned bits. Simmer for 2 minutes to reduce slightly. Stir in the cream, bring to a gentle simmer, and cook for 2–3 minutes until it thickens enough to coat a spoon.
6. Add cheese and greens. Lower the heat and stir in the Parmesan until smooth. Add the spinach or kale and let it wilt. Season with the remaining 1/2 teaspoon salt, a pinch of red pepper flakes (if using), and the lemon zest and juice.
7. Combine chicken and sauce. Return the cooked chicken and any juices to the skillet. Toss to coat and simmer 1 minute to marry the flavors. Taste and adjust salt, pepper, and lemon.
8. Assemble. Add the spaghetti squash strands to the skillet, gently tossing to soak up the sauce. If your skillet isn’t large enough, combine in a big bowl. Finish with chopped fresh basil and an extra sprinkle of Parmesan.
9. Serve. Spoon into bowls. For a restaurant touch, drizzle with a little olive oil and add a few extra slivers of sun-dried tomato on top.

Why This Recipe Works

Save

Spaghetti squash is the perfect stand-in for pasta when you want a lighter base that still holds up to a creamy sauce. The squash’s gentle sweetness pairs beautifully with the savory, tangy punch of sun-dried tomatoes.

Using chicken thighs (or breast if you prefer) adds protein and keeps the dish satisfying. A splash of cream and Parmesan creates silky body without feeling heavy. Fresh basil and a squeeze of lemon at the end brighten everything so the flavors pop.

Keeping It Fresh

Store leftovers in an airtight container in the fridge for up to 4 days. The sauce thickens as it sits, so add a splash of broth or water when reheating to loosen it.

Reheat gently on the stove over low heat or in the microwave in 45-second bursts, stirring between rounds. If you plan ahead for meal prep, keep the squash and sauce in separate containers and combine when reheating for the best texture.

Health Benefits

• Lower-carb base: Spaghetti squash brings satisfying volume with fewer carbs and calories than pasta, while still offering fiber.
• Protein-rich: Chicken makes this a filling, balanced meal that helps keep you full longer.
• Lycopene boost: Sun-dried tomatoes are packed with lycopene, an antioxidant linked to heart health.
• Greens on board: Spinach or kale adds iron, folate, and vitamins A and K without overwhelming the dish.
• Customizable richness: You control the creaminess by choosing heavy cream, half-and-half, or even a light cream plus extra broth.

What Not to Do

• Don’t over-roast the squash. If it turns mushy, you’ll lose those noodle-like strands. Pull it when it’s tender but still a bit firm.
• Don’t skip seasoning layers. Salt the squash, the chicken, and the sauce.

  Small pinches at each step make the final dish taste vibrant.

• Don’t boil the cream hard. A rapid boil can cause separation. Keep it at a gentle simmer for a silky sauce.
• Don’t overcrowd the pan with chicken. Crowding steams the meat. Cook in batches for a golden sear and better flavor.
• Don’t add lemon too early. Add zest and juice at the end so the brightness stays intact.

Variations You Can Try

• Roasted cherry tomatoes: Toss a handful with olive oil and salt, roast alongside the squash, and stir in for bursts of freshness.
• Mushroom upgrade: Sauté sliced cremini or shiitake with the garlic for extra umami and a meatier bite.
• Dairy-lighter: Use half-and-half and stir in a spoonful of Greek yogurt off the heat for added tang and creaminess.
• Spice it up: Add more red pepper flakes, or swirl in a little Calabrian chili paste.
• Herb swap: Try thyme or rosemary instead of Italian seasoning.

  Finish with parsley if you’re out of basil.

• Bacon or pancetta: Crisp a few slices first, then build the sauce in the drippings for a smoky spin.
• Vegetarian route: Swap chicken for white beans or chickpeas and use veggie broth. It stays hearty and satisfying.

FAQ

Can I cook the spaghetti squash in the microwave?

Yes. Pierce the whole squash several times with a knife, microwave for 4–5 minutes to soften, then halve, seed, and microwave cut side down in a dish with a bit of water for 8–12 minutes until tender.

Roasting gives more caramelized flavor, but the microwave is quick and convenient.

What can I use instead of heavy cream?

Half-and-half works well, or use 1/2 cup evaporated milk plus a splash of broth. For a dairy-lighter option, add 1/2 cup unsweetened cashew cream or coconut milk, then balance with extra lemon and Parmesan (or nutritional yeast if dairy-free).

Do I have to use oil-packed sun-dried tomatoes?

Oil-packed deliver richer flavor and a silkier sauce. If you only have dry-packed, rehydrate them in hot water for 10 minutes, drain well, and add an extra teaspoon of olive oil to the pan.

Can I make this ahead?

Absolutely.

Roast and shred the squash up to 3 days ahead. Cook the chicken and sauce up to 2 days ahead. Reheat gently and combine before serving.

Add a splash of broth to loosen the sauce.

How do I keep the sauce from curdling?

Keep the heat moderate, avoid rapid boiling after adding cream, and bring cold dairy closer to room temperature before stirring it in. Add lemon juice at the end and whisk in the Parmesan off the heat for extra insurance.

What’s the best way to cut spaghetti squash safely?

Microwave the whole squash 3–4 minutes to soften the rind slightly. Place it on a towel-lined cutting board for grip, then slice lengthwise with a sharp chef’s knife, keeping your non-cutting hand on top, not in front of the blade.

Can I freeze leftovers?

You can, but the squash will release more water after thawing.

If freezing, store the sauce and chicken separately from the squash for up to 2 months. Thaw overnight and reheat gently, then combine and cook off excess moisture if needed.
