How to Cook Spaghetti Squash
Spaghetti squash only takes on its signature noodle-like strands with the right roasting setup, cut wrong or roasted the wrong way up and it turns mushy or stays undercooked in the center. This walks through the roasting method that reliably gets long, distinct strands every time.
Steps
- 1Preheat the oven to 400°F (200°C).
- 2Slice the spaghetti squash in half lengthwise, from stem to base. If the whole squash is hard to cut, microwave it whole for 3-4 minutes first to soften the skin.
- 3Scoop out the seeds and stringy pulp from the center with a spoon, just like a pumpkin.
- 4Drizzle the cut sides with olive oil and season with salt and pepper.
- 5Place both halves cut-side down on a parchment-lined baking sheet.
- 6Roast for 40-50 minutes, until the skin gives slightly when pressed and a fork slides in easily.
- 7Let the squash cool for about 10 minutes, it holds heat and can burn fingers if handled right away.
- 8Using a fork, scrape the flesh lengthwise from the skin. It separates into long, spaghetti-like strands.
Common mistakes
- Roasting cut-side up: cut-side down traps steam and keeps the flesh moist; cut-side up dries the strands out on the surface while leaving the center undercooked.
- Undercooking: if a fork doesn't glide through easily, the strands come out short and won't separate cleanly. Give it the full roasting time rather than checking too early.
- Not draining excess moisture: spaghetti squash holds a lot of water. If the dish will sit or be sauced, salt the strands lightly and let them sit in a colander for a few minutes to release extra liquid.
Equipment
- Sharp chef's knife
- Baking sheet
- Parchment paper (optional)
- Fork
FAQ
Can I microwave spaghetti squash instead of roasting it?
Yes, it's faster but the strands turn out softer and wetter. Halve and seed it, place cut-side down in a microwave-safe dish with an inch of water, and microwave 10-12 minutes for an average-size squash, checking for fork-tenderness.
How do I know when spaghetti squash is done?
A fork should slide into the flesh with almost no resistance, and the skin gives slightly when pressed. If the fork meets resistance, the strands will be short and won't separate cleanly, give it more time rather than pulling it early.
Why did my spaghetti squash come out watery?
Spaghetti squash naturally holds a lot of water. Salt the scraped strands lightly and let them sit in a colander for 5-10 minutes before saucing or serving to draw out the extra liquid.
