My friend Sarah introduced me to this dish during what she called her 'winter detox,' and I was skeptical about squash replacing pasta. But the first time those tender strands caught the bright lemon garlic sauce, I understood the obsession completely. Now its the meal I make when I want something that feels indulgent but still leaves me light and energized afterward.

Last Tuesday my neighbor dropped by unexpectedly while I had this bubbling away on the stove. She ended up staying for dinner and texting me the next day asking for the recipe. Thats when I knew this wasnt just healthy food, it was company food.

Ingredients

  • Large spaghetti squash: The magic happens here as it transforms into those incredible pasta like strands that catch every drop of sauce
  • Olive oil: Essential for roasting the squash until perfectly tender and creating that golden sear on the chicken
  • Chicken breasts: Cut into bite sized pieces so they cook quickly and stay juicy while absorbing all that lemon flavor
  • Fresh garlic: Mince it right before adding so it releases its aromatic oils into the pan
  • Lemon: Both zest and juice are non negotiable here for that bright, fresh finish that cuts through the richness
  • Dried oregano: Adds an earthy, Mediterranean note that ties everything together beautifully
  • Fresh parsley: Brings color and a fresh herbal finish that balances the garlic
  • Parmesan cheese: The salty, nutty finish makes this feel like a real treat despite being so light

Instructions

Roast the squash to perfection:
Cut that squash in half lengthwise, scoop out the seeds, and give it a good rub with olive oil, salt, and pepper before roasting cut side down at 400°F until a fork slides through the flesh like butter.
Season the chicken while you wait:
Toss those bite sized chicken pieces with salt, pepper, oregano, and about half the lemon zest so every bite is flavorful from the inside out.
Sear the chicken golden:
Heat your olive oil in a large skillet until it shimmers, then add the chicken in a single layer, letting it develop a gorgeous golden crust before flipping, about 6 to 8 minutes total.
Build that garlic lemon sauce:
Stir in the minced garlic just until fragrant, then add the remaining lemon zest, all that bright lemon juice, and the parsley, letting everything bubble together for just a minute to marry the flavors.
Bring it all together:
Use a fork to scrape that roasted squash into strands, pile it onto plates, spoon over the lemon garlic chicken with every drop of that pan sauce, and finish with a generous dusting of Parmesan.

Make It Your Own

Ive learned that a pinch of red pepper flakes in with the garlic adds this lovely warmth that balances the lemon perfectly. Sometimes I throw in some spinach at the end just to wilt it into the sauce because why not sneak in more greens.

Perfecting the Squash

The key is not undercooking the squash, but also not letting it go mushy. You want those strands to have a little bite to them, just like al dente pasta, which usually happens right around the 40 minute mark depending on your squash size.

Serving Suggestions

This dish is beautiful on its own but a simple arugula salad with a balsamic vinaigrette makes it feel like restaurant quality dinner. A crisp white wine like Sauvignon Blanc cuts through the lemon and complements the garlic beautifully.

  • Serve immediately while the chicken is still hot and the sauce is at its most vibrant
  • Pass extra lemon wedges at the table for those who love an extra bright hit
  • Save any leftovers for lunch the next day when the flavors have had even more time to develop

Recipe Questions & Answers

How do I know when spaghetti squash is done roasting?

The squash is ready when the flesh feels tender when pierced with a fork and the strands separate easily. This typically takes 40-45 minutes at 400°F. Let it cool slightly before scraping to avoid burning your hands.

Can I use chicken thighs instead of breasts?

Absolutely. Chicken thighs work wonderfully and provide a juicier result. Adjust cooking time by 2-3 minutes since thighs may take slightly longer to cook through completely.

Is this dish suitable for meal prep?

Yes, this dish reheats well. Store the roasted squash and chicken separately in airtight containers for up to 4 days. Reheat gently and combine before serving with fresh Parmesan.

What can I serve alongside this dish?

A crisp green salad with vinaigrette complements the flavors beautifully. Steamed vegetables like broccoli or asparagus also work well. A slice of crusty gluten-free bread completes the meal.

How do I make this dairy-free?

Simply omit the Parmesan or substitute with a plant-based alternative. The lemon garlic sauce provides plenty of flavor on its own, so you won't miss the cheese.

Can I add vegetables to the chicken while cooking?

Certainly. Bell peppers, cherry tomatoes, or spinach can be added during the last few minutes of cooking. Just ensure they don't release too much water into the pan sauce.

What You'll Need

For the Spaghetti Squash

01 1 large spaghetti squash, about 3 lbs
02 1 tablespoon olive oil
03 ½ teaspoon kosher salt
04 ¼ teaspoon black pepper

For the Lemon Garlic Chicken

01 1 lb boneless skinless chicken breasts, cut into bite-sized pieces
02 2 tablespoons olive oil
03 4 cloves garlic, minced
04 1 lemon, zested and juiced
05 ½ teaspoon dried oregano
06 ½ teaspoon salt
07 ¼ teaspoon black pepper
08 2 tablespoons fresh parsley, chopped

For Serving

01 ½ cup freshly grated Parmesan cheese
02 Extra lemon wedges, optional
03 Fresh parsley for garnish

How to Make It

Step 01

Roast the Spaghetti Squash: Preheat the oven to 400°F. Cut the spaghetti squash in half lengthwise and remove the seeds. Drizzle the cut sides with olive oil, then season with salt and pepper. Place cut-side down on a parchment-lined baking sheet and roast for 40–45 minutes until tender and strands separate easily with a fork. Set aside to cool slightly.

Step 02

Season the Chicken: While the squash roasts, season the chicken pieces with salt, pepper, oregano, and half the lemon zest.

Step 03

Cook the Chicken: Heat 2 tablespoons olive oil in a large skillet over medium-high heat. Add the seasoned chicken and cook, stirring occasionally, until golden brown and cooked through, about 6–8 minutes.

Step 04

Add Aromatics: Stir in the minced garlic and cook for 1 minute until fragrant. Add the remaining lemon zest, lemon juice, and chopped parsley. Cook for an additional 1–2 minutes, then remove from heat.

Step 05

Prepare the Squash Strands: Once the squash is cool enough to handle, use a fork to scrape the flesh into spaghetti-like strands.

Step 06

Assemble and Serve: Divide the squash strands among plates. Top each portion with the lemon garlic chicken and pan sauce. Sprinkle with Parmesan cheese and extra fresh parsley. Serve with lemon wedges if desired.
