# What You'll Need:

→ For the Spaghetti Squash

01 - 1 large spaghetti squash (about 3 lbs)
02 - 2 tsp olive oil
03 - 1/2 tsp salt
04 - 1/4 tsp black pepper

→ For the Chicken

05 - 2 boneless, skinless chicken breasts (about 1 lb), diced
06 - 1 tbsp olive oil
07 - 1/2 tsp salt
08 - 1/4 tsp black pepper
09 - 1/2 tsp Italian seasoning

→ For the Alfredo Sauce

10 - 2 tbsp unsalted butter
11 - 4 cloves garlic, minced
12 - 1 cup heavy cream
13 - 1 cup freshly grated Parmesan cheese
14 - 1/4 tsp ground nutmeg
15 - Salt and pepper to taste

→ Vegetables and Add-ins

16 - 4 cups fresh baby spinach
17 - 1/4 cup chopped fresh parsley (optional)
18 - 1/4 cup grated Parmesan (for garnish)

# How To Make It:

01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - Slice the spaghetti squash in half lengthwise. Scoop out the seeds and pulp. Drizzle the cut sides with olive oil, and season with salt and pepper. Place cut-side down on the baking sheet and roast for 35–40 minutes, until tender.
03 - While the squash roasts, heat 1 tbsp olive oil in a large skillet over medium-high heat. Add diced chicken, season with salt, pepper, and Italian seasoning. Sauté for 6–8 minutes until cooked through and lightly golden. Remove from skillet and set aside.
04 - In the same skillet, melt butter over medium heat. Add minced garlic and cook for 1 minute until fragrant. Pour in heavy cream and bring to a gentle simmer.
05 - Whisk in Parmesan cheese and nutmeg until smooth and creamy. Season with salt and pepper to taste.
06 - Add baby spinach to the sauce and cook for 1–2 minutes until wilted. Return the cooked chicken to the skillet and stir to coat.
07 - When the spaghetti squash is cool enough to handle, use a fork to scrape the strands into a large bowl. Add the squash strands to the skillet and toss everything together until well combined and heated through. Serve immediately, garnished with chopped parsley and extra Parmesan, if desired.

# Expert Suggestions:

01 -
  • You get all the creamy Alfredo satisfaction without the post-pasta food coma
  • The roasted squash naturally absorbs that garlicky Parmesan sauce better than noodles ever could
02 -
  • Let the squash cool for at least 10 minutes before scraping, otherwise you will burn your fingers trying to handle hot squash halves
  • The sauce will thicken as it sits off the heat, so if it looks too thin just give it a minute before adding more cheese
03 -
  • Grate your own Parmesan from a wedge, because the pre-grated stuff contains cellulose that prevents it from melting smoothly
  • Do not let the garlic brown, or it will turn bitter and ruin the delicate flavor of the sauce
