How to Cook Spaghetti Squash – 4 Easy Methods

1. Oven Roasted (Halved) — Most Flavorful

This is the most popular method and gives the best flavor and texture.

Prep time: 10 minutes
Cook time: 35–45 minutes
Total time: ~50 minutes

What you’ll need:

1 spaghetti squash
Olive oil
Salt and pepper
Baking sheet
Sharp knife and spoon

Instructions:

Preheat your oven to 400°F (200°C).
Carefully cut the squash in half lengthwise (stem to end). Scoop out the seeds with a spoon.
Drizzle the cut sides with olive oil, and sprinkle with salt and pepper.
Place squash cut-side down on a parchment-lined or lightly greased baking sheet.
Roast for 35–45 minutes, depending on the size. It’s done when the flesh is fork-tender.
Flip it over, let cool for a few minutes, then shred the strands with a fork.

Pro tip: Roasting cut-side down caramelizes the edges and keeps the moisture in.

2. Oven Roasted (Whole) — Easiest to Prep

Great for those who don’t want to deal with cutting a raw squash.

Prep time: 2 minutes
Cook time: 60–70 minutes
Total time: ~1 hour 10 minutes

What you’ll need:

1 whole spaghetti squash
Knife
Baking sheet

Instructions:

Preheat oven to 400°F (200°C).
Pierce the squash a few times with a sharp knife to let steam escape.
Place the whole squash on a baking sheet.
Roast for 60–70 minutes, turning once halfway through.
Let it cool slightly, then cut in half, remove the seeds, and scrape into strands with a fork.

Pro tip: This method is mess-free and safe, especially if you’re nervous about cutting raw squash

3. Microwave (Quickest Method)

Great for when you’re short on time.

Prep time: 5 minutes
Cook time: 10–12 minutes
Total time: ~15 minutes

What you’ll need:

1 spaghetti squash
Knife
Microwave-safe dish with lid

Instructions:

Cut the squash in half lengthwise and scoop out the seeds.

Cover with a microwave-safe lid or plastic wrap (leave a small gap for steam).
Microwave on high for 10–12 minutes, or until tender.
Let cool slightly, then scrape with a fork to get strands.

Pro tip: If your squash is too hard to cut, microwave it whole for 3–5 minutes first to soften.

4. Instant Pot / Pressure Cooker — Fast & Hands-Off

Great for batch-cooking or softening squash for other recipes.

Prep time: 5 minutes
Cook time: 7–8 minutes (plus pressure build & release)
Total time: ~20 minutes

What you’ll need:

1 spaghetti squash (whole or halved)
1 cup water
Trivet or steamer basket

Place the trivet or basket in the Instant Pot and pour in 1 cup of water.
Place the whole squash (or halved) on the trivet.
Close the lid, set the valve to sealing, and cook on high pressure for 7–8 minutes.
Quick release the pressure carefully.
Let it cool slightly, cut in half (if whole), remove seeds, and shred into strands.

Pro tip: Halving the squash before cooking may reduce the time by about two minutes.
