The first time I served this, my friend actually asked what restaurant I ordered from. That crispy garlic smell hits you before you even reach the table. I'd been experimenting with spaghetti squash for weeks, trying to make it feel like a real meal instead of diet food. This lemon garlic chicken was the game changer I needed.

Last Tuesday, I made this for my sister who swears she hates healthy food. She went back for seconds and asked for the recipe before she even left. Watching someone realize that good-for-you can actually mean good-to-eat never gets old.

Ingredients

  • Large spaghetti squash: Pick one that feels heavy for its size with firm, unblemished skin
  • Olive oil: This helps the squash roast evenly and develop those golden edges
  • Kosher salt: Essential for drawing out moisture and concentrating flavor
  • Boneless chicken breasts: Cutting them into bite-sized pieces helps them cook faster and stay tender
  • Fresh garlic: Dont use jarred garlic here, the fresh stuff makes all the difference
  • Lemon: Youll need both zest and juice to get that bright, punchy flavor throughout
  • Dried oregano: Adds an earthy note that keeps the dish from feeling too one-note
  • Fresh parsley: Brings color and a fresh bite that cuts through the rich chicken
  • Parmesan cheese: The salty finish pulls everything together

Making It Your Own

Sometimes I toss in a handful of spinach at the very end so it wilts into the pan juices. Other times, I add red pepper flakes if I want a little warmth that cuts through the lemon.

Timing Is Everything

Start the squash first and let it roast while you prep and cook the chicken. By the time the chicken is done, the squash should be perfectly tender and ready to scrape.

Leftovers That Actually Work

The flavors get even better overnight, which makes this perfect for meal prep. Store the squash and chicken separately and reheat gently so nothing dries out.

  • Reheat the squash with a splash of water to keep it from getting dry
  • The chicken benefits from a quick warm-up in a skillet rather than the microwave
  • Add a fresh squeeze of lemon before serving leftovers to wake everything back up

Recipe FAQs

How do I know when the spaghetti squash is done roasting?

The squash is ready when the flesh is tender and easily separates into strands with a fork. This typically takes 40-45 minutes at 400°F. You should be able to scrape the flesh without resistance.

Can I use chicken thighs instead of breasts?

Absolutely. Chicken thighs will yield a juicier result due to their higher fat content. Adjust the cooking time slightly—thighs may need an extra 2-3 minutes to cook through completely.

Is this dish suitable for meal prep?

Yes, it reheats beautifully. Store the squash and chicken separately in airtight containers for up to 4 days. Reheat gently in the microwave or skillet, adding a splash of water if needed to refresh the squash.

How can I make this dairy-free?

Simply omit the Parmesan or substitute it with a plant-based alternative. The lemon garlic flavors remain vibrant and satisfying without the cheese.

What wine pairs well with this dish?

A crisp Sauvignon Blanc complements the bright lemon flavors beautifully. Alternatively, a light Pinot Grigio or dry Chardonnay would work well.

Can I add extra vegetables to the skillet?

Certainly. Spinach, cherry tomatoes, or bell peppers can be added during the last few minutes of cooking. They'll absorb the lemon garlic flavors and add color and nutrients.

For the Spaghetti Squash

01 1 large spaghetti squash (about 3 lbs)
02 1 tbsp olive oil
03 ½ tsp kosher salt
04 ¼ tsp black pepper

For the Lemon Garlic Chicken

01 1 lb boneless skinless chicken breasts, cut into bite-sized pieces

For Serving

01 ½ cup freshly grated Parmesan cheese

How To Make It

Step 01

Roast the Squash: Preheat the oven to 400°F. Halve the spaghetti squash 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.

Step 02

Cook the Squash: Roast for 40–45 minutes, until the flesh is tender and strands separate easily with a fork. Set aside to cool slightly.

Step 03

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

Step 04

Sear the Chicken: In a large skillet, heat 2 tbsp olive oil over medium-high heat. Add the chicken and cook, stirring occasionally, until golden and cooked through, about 6–8 minutes.

Step 05

Add Aromatics: Add the minced garlic and cook for 1 minute, until fragrant.

Step 06

Finish the Sauce: Stir in the remaining lemon zest, lemon juice, and chopped parsley. Cook for 1–2 minutes, then remove from heat.

Step 07

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

Step 08

Assemble the Dish: Divide the squash among plates. Top each with the lemon garlic chicken and pan sauce.

Step 09

Garnish and Serve: Sprinkle with Parmesan and extra parsley. Serve with lemon wedges if desired.
