If you’ve ever wondered how to turn spaghetti squash into perfect noodle-like strands, you’re in the right place!

You can watch the quick video, scroll through the step-by-step photos, or grab the printable recipe card at the bottom—whichever way you like to learn.

Spaghetti squash is a type of winter squash that becomes long, noodle-like strands when cooked. These veggie “noodles” are naturally gluten-free, lower in carbs than pasta, and high in fiber, calcium, and potassium. When roasted correctly, they’re tender, slightly sweet, and make the perfect base for your favorite sauces.

Why Use Spaghetti Squash Instead of Pasta?

• Naturally gluten-free: An easy swap for anyone avoiding wheat.
• Low in calories & carbs: A lighter choice that still satisfies.
• Nutrient-dense: Provides fiber, vitamin A, vitamin C, potassium, and antioxidants.
• Versatile: Works with marinara, pesto, butter, or any sauce you love.

It’s also a fun way to get more vegetables on your plate—especially if you’re cooking for picky eaters.

How to Cook Spaghetti Squash Noodles

Step 1: Preheat the Oven to 400°F (204° C)

Heat your oven to 400°F (204°C). Line a rimmed baking sheet with parchment paper or a silicone baking mat for easy cleanup.

Step 2: Slice an Inch Off the Top and Bottom of the Spaghetti Squash, Then Slice Down the Middle

Cut about 1 inch off both ends of the squash (the stem end and bottom). Then, using a large, sharp knife, carefully slice the squash lengthwise. Cutting can be the hardest part—go slowly and make sure the squash is stable.

Remember to use the biggest knife you have and proceed slowly. It may take a few minutes, but prioritizing safety is always better than risking an accident.

 

Step 3: Using a Spoon, Scrape Out All of the Seeds and Flesh

Use a spoon to scrape out the seeds and stringy bits. (Save the seeds if you’d like to roast them later for a snack—similar to pumpkin seeds.)

Step 4: Brush the Inside of the Squash with Olive Oil

Brush the cut side of the squash halves with a little olive oil. Place them cut side down on your prepared baking sheet.

Pro tip: In arid climates, you can add one or more tablespoons to the baking sheet if needed to retain moisture. I typically don’t do this because I find it can make the noodles too wet, but in a very dry climate, this might help.

Step 5: Roast the Spaghetti Squash for 30-40 Minutes Until the Flesh is Fork-Tender

Bake for 30–40 minutes, until the flesh is fork-tender. The outside will still be firm, but the inside should easily shred into strands.

Step 6: Let it Cool, Then Scrape Out Your Spaghetti Squash Noodles

Let the squash cool for at least 10–15 minutes. Use a fork to scrape the inside lengthwise—you’ll see noodle-like strands form.

That’s it! Fresh, golden spaghetti squash noodles ready to serve.

Storage Tips

Spaghetti Squash FAQ

Can I cook spaghetti squash in the microwave?

Yes! Pierce the squash whole with a fork several times, then microwave for 5–7 minutes to soften it. This makes cutting easier. Slice, remove seeds, then microwave the halves cut side down for 10–12 more minutes until tender.

Should I roast spaghetti squash whole or cut in half?

You can do either. Roasting squash halves cut side down gives the best texture and caramelization. Roasting the squash whole works too—it just takes longer and is trickier to scoop.

How do I know when the squash is done?

The flesh should be tender when pierced with a fork and easily pull into noodle-like strands.

Can I freeze spaghetti squash noodles?

Yes, but they tend to get watery when thawed. If freezing, press out excess moisture first, then store in freezer-safe bags for up to 2 months.

How much protein is in spaghetti squash?

Spaghetti squash is not a high-protein food (about 1g per cup). To make it a balanced meal, pair it with a protein source like chicken, beans, or ground turkey.
