Ingredients

For spaghetti squash

  • 1 spaghetti squash, about 3-1/2 pounds
  • 1 tablespoon olive oil
  • 1/4 teaspoon kosher salt
  • 1/4 teaspoon black pepper
  • Pinch of red pepper flakes

For tomatoes

  • 1 pint cherry tomatoes or grape tomatoes, halved
  • 1 tablespoon olive oil
  • 1/4 teaspoon kosher salt
  • 1/4 teaspoon black pepper

For spinach

  • 1 tablespoon olive oil
  • 1 garlic clove, minced
  • 3 ounces baby spinach
  • Shaved or grated Parmesan for serving

Instructions

  • Preheat the oven to 400 degrees F. Line 2 sheet pans with parchment paper.
  • Slice the spaghetti squash in half lengthwise and scoop out the seeds. Drizzle the cut sides with 1 tablespoon olive oil and season with 1/4 teaspoon kosher salt, 1/4 teaspoon black pepper and red pepper flakes. Place the squash cut-side down on one of the baking sheets. Roast for 40-45 minutes until the squash can be easily pierced with a knife.  
  • When the squash is cool enough to handle, use a fork remove the flesh.
  • On the other sheet pan, toss the tomatoes with 1 tablespoon olive oil, 1/4 teaspoon kosher salt and 1/4 teaspoon black pepper. Arrange the tomatoes, so they are cut side up. Roast them for 25-30 minutes until they are wrinkled, but still juicy in the middle.
  • Heat 1 tablespoon olive oil in a large skillet or sauté pan over medium high heat. Sauté the garlic until it is fragrant, about 30 seconds.
  • Stir the spaghetti squash into the sautéed garlic.
  • Then fold in spinach giving it a couple minutes to wilt. 
  • Gently stir in the roasted tomatoes. Top with grated parmesan.

Notes

If it is not tomato season, you can use jarred sun-dried tomatoes or marinated roasted tomatoes. Drain the oil from the jar and then chop them, so you have about 1 cup chopped sun-dried tomatoes. 
Let leftovers cool to room temperature and then store them in an airtight container in the refrigerator up to 3 days. Reheat them in the microwave and garnish with additional grated Parmesan.
To make the recipe vegan, leave out the Parmesan or use a plant-based substitute.
