Place the spaghetti squash on a stable cutting board – if needed, place a damp towel under the cutting board to prevent sliding.
Hold one end of the squash with your non-dominant hand, and using a sharp chef’s knife, pierce the squash in the middle and cut through the squash length-wise.
Then turn the squash vertically and cut through the other end of the squash.
Using a spoon, scrape and scoop out the seeds.
Oven Method:
Preheat the oven to 400°F (200°C).
Place the spaghetti squash halves, cut side up, on a baking sheet, lined with a parchment paper.
Then drizzle olive oil all over and generously salt and pepper.
Bake for 40-45 minutes, or until it's fork tender.
Cool the squash until safe to handle and then scrape the flesh with a fork to reveal the strands.
Instant Pot Method:
Place a rack in inner pot of Instant Pot and add 1 cup of water.
Put squash halves and close the pot.
Set the Instant Pot for 8 minutes on High pressure.
Once the timer is up, release the pressure right away. And carefully open the lid. Remove the squash using a pair of kitchen tongs.
Cool the squash until safe to handle and then scrape the flesh with a fork to reveal the strands.
Refrigerate the cooked spaghetti squash in an airtight container for up to 5 days.
