How to Make Spaghetti Squash
Spaghetti squash only turns into long noodle-like strands when it's cut, seasoned, and cooked the right way. Get the orientation or timing wrong and it either stays crunchy in the center or turns into wet mush that clumps instead of shredding.
Steps
- 1Choose a squash that's firm, heavy for its size, and free of soft spots; a 3-4 pound squash yields about 4-5 cups of strands.
- 2Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.
- 3Cut the squash in half lengthwise, from stem to base, using a sturdy chef's knife (microwave the whole squash for 3-4 minutes first if the skin is too hard to cut through).
- 4Scoop out the seeds and stringy pulp from the center of each half with a spoon, leaving the firm flesh intact.
- 5Rub the cut sides with 1-2 teaspoons of olive oil per half and season with salt and pepper.
- 6Place both halves cut-side down on the prepared baking sheet so the flesh steams against the pan.
- 7Roast for 40-50 minutes, until the skin dents slightly under light pressure and a fork slides through the thickest part with little resistance.
- 8Let the squash cool for 10 minutes, then run a fork lengthwise through the flesh in long strokes to pull the strands loose from the shell.
- 9Transfer the strands to a colander, salt lightly, and let them sit for 5-10 minutes to drain off excess water before serving or tossing with sauce.
Common mistakes
- Roasting cut-side up: this lets moisture escape as steam instead of staying in contact with the flesh, drying out the edges before the center finishes cooking.
- Pulling the strands right out of the oven: hot squash still has loose water bound in the flesh, and forking it immediately releases that water into whatever sauce it's tossed with.
- Skipping the fork test: squash that isn't fully soft yields short, stiff strands that won't separate cleanly no matter how long it's forked.
- Cutting through the widest part instead of stem to base: cutting the wrong way shortens the strands considerably since spaghetti squash fibers run lengthwise.
Equipment
- Sturdy chef's knife
- Baking sheet with parchment paper
- Metal spoon for scooping seeds
- Fork for shredding
- Colander
FAQ
Can spaghetti squash be microwaved instead of roasted?
Yes. Halve it, scoop the seeds, place cut-side down in a microwave-safe dish with an inch of water, and microwave on high for 10-12 minutes per half. It cooks faster but the strands come out noticeably softer and wetter than roasted squash.
How do I know when spaghetti squash is fully cooked?
A fork should push through the thickest part of the flesh with almost no resistance, and the outer skin should give slightly when pressed with a thumb.
Why did my spaghetti squash turn out watery?
The flesh naturally holds a lot of water, which is why draining the forked strands in a colander for 5-10 minutes with a little salt makes a real difference before adding sauce.
Can spaghetti squash be roasted whole without cutting it first?
Yes, poke several holes in the skin with a knife and roast it whole at 400°F for about an hour, then let it cool before cutting and scooping. This method takes longer but is useful if the squash is too hard to cut when raw.
How long does cooked spaghetti squash keep in the fridge?
Cooked strands keep in an airtight container for 4-5 days and reheat well in a dry skillet, which also helps evaporate any remaining moisture.
