  • 1 (2½ pound) 2½- to 3-pound spaghetti squash, halved lengthwise and seeded
  • 1 ripe avocado
  • 1 cup packed basil leaves
  • ¼ cup unsalted shelled pistachios
  • 2 tablespoons lemon juice
  • 1 clove garlic
  • ¾ teaspoon salt, divided
  • ½ teaspoon ground pepper, divided
  • 5 tablespoons extra-virgin olive oil, divided
  • 1 pound skinless, boneless chicken breasts, trimmed and cut into 1-inch pieces


  • Prep

  • Ready In

  1. Preheat oven to 400°F. Coat a large rimmed baking sheet with cooking spray.
  2. Place squash, cut-side down, on one side of the prepared pan. Bake until tender, about 45 minutes.
  3. Meanwhile, combine avocado, basil, pistachios, lemon juice, garlic, ½ teaspoon salt and ¼ teaspoon pepper in a food processor. Pulse until finely chopped. Add 4 tablespoons oil and process until smooth.
  4. Ten minutes before the squash is done, toss chicken, the remaining 1 tablespoon oil and the remaining ¼ teaspoon each salt and pepper together in a medium bowl. Spread the chicken in an even layer on the empty side of the baking sheet. Return to the oven and bake until just cooked through, about 10 minutes.
  5. Using a fork, scrape the squash from the shells into a large bowl. Add the chicken and toss gently to combine. Serve topped with the pesto.

This is a very satisfying meal and will make again! Instead of adding 4T of oil to the pesto I used 2 T oil and 2 T water. Brushed 1/2 T oil on squash before roasting and added 1 T oil to shredded squash to moisten a bit. I added one wedged purple onion and sliced red pepper to chicken and roasted it all together Mixed in several handfuls of chopped spinach/arugula mix to shredded squash and divided into 5 portions instead of 4. I bought stir-fry chicken breast which saved time.

This was delicious. Even my 15 year old son went back for seconds! I added garlic powder, paprika and onion powder to the chicken before cooking it and I added a sliced red pepper to the same pan when I added the chicken. Everything else was as in the recipe. The sauce was sooo tasty and it was much more filling than I expected. Will definitely make again.

A most happy result, packed full of flavor and goodness we all had seconds. The only thing I changed is I drizzled on the finished squash some excellent EVOO from California Olive Ranch. The chicken was good but not essential so next time I’ll invite my vegan sister in law and leave off the chicken.

I love the pesto in this recipe. Based on previous comments I added a clove of garlic and 1/4 cup of diced onion and red pepper along with some chopped kale for color. I cooked it all with the chicken and it was amazing. Had the leftovers for lunch and it was still great the next day.

I made this today for lunch today. The avocado pesto was a surprise, I really like it. I'm taking leftovers to work for lunch tomorrow so I hope it doesn't turn brown. This recipe is filling and tasty. Next time I will experiment with adding different spices to the pesto to give it some kick because I feel like it's missing some depth of flavour.
