Methods for Cooking Spaghetti Squash

Here are the most popular methods for cooking spaghetti squash. Choose whichever suits your preference.

1. Roasting

  • Preheat oven: Set your oven to 400°F (200°C).
  • Prep the squash: Cut the squash in half lengthwise, and scoop out the seeds and stringy pulp.
  • Season: Drizzle the cut sides with olive oil, sprinkle with salt and pepper.
  • Roast: Place squash cut-side down on a baking sheet. Roast for 30-45 minutes, or until a fork easily pierces the flesh.
  • Shred: Once cool enough to handle, use a fork to shred the squash into “spaghetti” strands.

2. Microwaving

  • Pierce: Poke a few holes in the whole squash with a fork for ventilation.
  • Microwave: Place squash on a microwave-safe plate. Microwave on high for 5-minute intervals until it yields slightly to pressure when squeezed. (Times vary depending on size).
  • Cool and prep: Let squash cool. Cut in half, remove the seeds, and shred.

3. Instant Pot

  • Trivet: Place a trivet or steamer basket in the Instant Pot and add 1 cup water.
  • Prep the squash: Cut the squash in half, remove seeds, and place cut-side down on the trivet.
  • Cook: Seal the Instant Pot. Cook on high pressure for 7 minutes (small squash) to 20 minutes (large squash). Let pressure release naturally for around 10 minutes.
  • Shred: When cool, shred the squash with a fork.


Test for doneness: The squash is ready when you can easily scrape the flesh into strands with a fork.

Avoid overcooking: Overcooked squash becomes mushy.

Be careful when cutting: Cutting a raw squash can be difficult. For easier slicing, microwave the whole squash for a few minutes to soften it slightly.

Serving suggestions: Serve spaghetti squash as a low-carb pasta substitute with your favorite sauce, toss with herbs and butter, or mix with roasted vegetables.

Enjoy your delicious and healthy spaghetti squash!
