Ingredients

  • 1 3-4 lb. spaghetti squash see note
  • splash of oil roasting only
  • salt and pepper

Instructions

For the Oven:

  • Preheat oven to 400ºF and line a baking sheet with foil
  • Cut spaghetti squash lengthwise (for short "noodles") or crosswise (for long "noodles") and scoop out seeds.
  • Scoop out seeds and discard.
  • Brush inside with oil, and sprinkle with salt and pepper.
  • Place facedown on baking sheet and bake for 45-50 minutes, or until you can pierce with a fork.
  • When cool enough to handle, scrape out "spaghetti" with a fork.
  • Cooked spaghetti squash will keep for 5 days in the refrigerator.

For the Instant Pot:

  • Cut spaghetti squash lengthwise (for short "noodles") or crosswise (for long "noodles") and scoop out seeds. Sprinkle with a pinch of salt.
  • Add 1 cup of water to the Instant Pot.
  • Stack the spaghetti squash on top of each other (cut-side up).
  • Close the lid and make sure the knob is turned to sealing.
  • Set to manual high-pressure for 10 minutes (longer time will be needed for bigger squash)
  • When the timer goes off, turn the vent on the top of the lid to venting to release the steam.
  • Once the venting knob has dropped, open the lid and shred the spaghetti squash with two forks to turn squash into spaghetti-like noodles!
  • Cooked spaghetti squash will keep for 5 days in the refrigerator.

Notes

If your spaghetti squash is a different size, you may have to adjust the cooking time, especially for the Instant Pot.
