Prep Time15 minutes
Cook Time1 hour 10 minutes
Total Time1 hour 25 minutes
Servings: 4 servings

Ingredients

  • 1 large spaghetti squash see notes
  • 2 tbsp olive oil
  • 2 tsp Italian herb blend or other seasoning of your choice
  • 3 tbsp basil pesto more or less to taste
  • 1 1/4 cups coarsely grated Parmesan cheese divided (1 cup for mixing, 1/4 cup for topping)
  • salt to taste
  • freshly ground black pepper to taste

Instructions

  • Preheat the oven to 400°F (200°C).
  • Wash the outside of the spaghetti squash, then cut it in half lengthwise. Trim the ends if desired.
  • Use a spoon to scrape out the seeds and fibrous strands from each half.
  • Rub the cut surfaces of the squash with 2 tablespoons olive oil and sprinkle evenly with the Italian herb blend.
  • Place the squash cut-side up on a baking sheet sprayed with non-stick spray and roast for 40–55 minutes, checking after 40 minutes, until the flesh is tender and can be scraped into spaghetti-like strands.
  • Let the squash cool a few minutes until safe to handle, then use a fork to scrape the strands into a mixing bowl and discard the skins.
  • Gently stir in 3 tablespoons pesto and 1 cup of the grated Parmesan until combined; season with salt and freshly ground black pepper to taste.
  • Transfer the squash mixture to a gratin or baking dish, sprinkle the remaining 1/4 cup Parmesan evenly over the top, and bake 20–30 minutes until the mixture is bubbling and the cheese is melted and starting to brown.
  • Remove from the oven and serve hot.
