Spaghetti Squash

  • l large spaghetti squash or two small ones
  • extra virgin olive oil
  • Salt and pepper


  • 1 large yellow onion diced
  • 1 pint cherry or grape tomatoes
  • 2 tbsp olive oil extra virgin
  • 1 cup California walnuts toasted, chopped
  • 2 garlic cloves minced
  • 2 cups spinach
  • salt to taste
  • pepper to taste
  • red chili flakes to taste
  • 4 oz crumbled goat cheese


How to Cook Spaghetti Squash

  • Preheat the oven to 375°F.
  • Cut off the stem and slice the spaghetti squash in half lengthwise. Scoop out the seeds and ribbing. It may be helpful to microwave the spaghetti squash for 5-6 minutes prior to cutting. The squash tends to be very hard.
  • Drizzle the inside of the squash with olive oil and sprinkle with salt and pepper.
  • Place the spaghetti squash cut side down on the baking sheet. Roast for 30 to 35 minutes or until lightly browned on the outside.
  • Remove from the oven and using oven mitts, flip the squash so that it’s cut side up. Use a fork, check to make sure the squash is done and you can easily scrape the squash aways from the sides. If not, flip and place back in the oven.
  • When cool to the touch, use a fork to scrape and fluff the strands from the sides of the squash.

How to Make the Sauce

  • Sauté the onion and cherry tomatoes in olive oil over medium heat. Cook until the onions are golden and the tomatoes are about to burst.
  • Turn down the heat to low and add 2 cloves of minced garlic and the spinach. Using a fork, mash some of the tomatoes to create a “tomato sauce”.
  • Add the spaghetti squash, chili flakes, salt, and pepper.
  • Stir in goat cheese and the toasted walnuts and enjoy!
