🔔🔔Spaghetti Squash Cooking Options 🔔🔔
1. Oven Roasted – Preheat oven to 400 degrees; line a rimmed baking sheet with parchment paper to prevent sticking. Cut your squash in half and remove the seeds and pulp. Brush the flesh of the squash with 2 tablespoons of olive oil, season generously with salt to help remove excess water. Place the 2 halves cut side down on the parchment lined baking sheet. Cook until tender 45-50 minutes (depending on size of squash).

2. Microwave– Cut your squash in half and remove the seeds and pulp. Place the squash cut side down in a microwave safe dish. Add in ½ an inch of water to the dish. Microwave on high for 10-15 minutes (maybe longer depending on size of squash) until a knife can easily pierce the flesh.

3. Boiling – Pierce your squash with a fork multiple times. Place the squash in a large stock pot and fill with water. Place lid on pot and bring water to a boil. Using tongs, every 5 minutes rotate the squash to ensure an even boil. After 15-20 minutes see if you can easily pierce the shell and flesh with a paring knife. Once squash is soft, remove from water and let cool for 15 minutes. Cut the squash in half and scrape out the seeds; use a fork to remove the flesh.

4. Instant Pot – Cut squash in half and remove seeds and pulp. Place the steamer insert into your pressure cooker and add 1 cup of water. Place the squash halves inside the pot cut side down. Place the lid on the pressure cooker. Cook under high pressure for 7 minutes. When squash is finished, release the valve at the top to quickly lower the pressure. Remove lid and check your squash for doneness. I find 7 minutes is usually enough, but if you are using a large squash, you may have to add 2-3 minutes more. Remove from pot and let cook for about 15 minutes before handling.
