Jump to RecipeThis method is especially helpful when you want something simple, reliable, and hands-off, perfect for busy days when you still want a wholesome, vegetable-forward meal without turning the kitchen upside down.
Why the Instant Pot Is Ideal for Cooking Spaghetti Squash
The Instant Pot makes cooking spaghetti squash easier than oven roasting and far more consistent than stovetop methods.
Here’s why it works so well:
- Even pressure cooking prevents mushy or uneven texture
- Steam keeps the squash tender without drying it out
- Cook time is predictable, even for beginners
- Minimal dishes compared to traditional methods
Because everything happens in one sealed pot, this approach naturally fits into low-effort cooking routines without extra steps or complicated prep.
Ingredients You’ll Need
- 1 medium spaghetti squash
- 1 cup water
That’s it. No oil, no seasoning required at this stage, which makes it easy to customize later.
How to Cook Spaghetti Squash in the Instant Pot

Preparing the Squash Safely
Start by washing the squash thoroughly. Using a sharp knife, carefully cut it in half lengthwise. If the squash feels too firm, you can microwave it for 2 to 3 minutes to soften the skin slightly, this makes cutting safer and easier.
Scoop out the seeds with a spoon and discard them.
Pressure Cooking Method
Pour 1 cup of water into the Instant Pot and place the trivet inside. Arrange the squash halves cut-side up on the trivet.
Seal the lid and cook on High Pressure.
Cooking time will vary slightly depending on size, but most medium squash cook evenly without issue.
Releasing Pressure Correctly
Once cooking is complete, allow a quick pressure release for firmer strands or a short natural release if you prefer slightly softer texture. Carefully open the lid and remove the squash using tongs.
Whole vs Halved Spaghetti Squash (Which Method Should You Use?)
Both methods work, but halving the squash offers better control and more consistent results.
- Halved squash: Faster cooking, easier to shred, more predictable texture
- Whole squash: No cutting required, but longer cook time and slightly softer strands
If texture matters to you, especially if you’re aiming for spaghetti-like strands, cutting the squash in half is the better choice.
How to Get Perfect Spaghetti-Like Strands
Let the squash rest for a minute after cooking. Then use a fork to gently scrape lengthwise along the flesh. The strands will separate naturally.
Avoid over-scraping, pressing too hard can break the strands and create a softer, mashed texture.
Serving Ideas That Actually Work

Spaghetti squash is neutral by nature, which makes it incredibly versatile. You can keep things simple or dress it up depending on the meal.
- Toss with olive oil, salt, and black pepper
- Serve with tomato-based or cream sauces
- Pair with grilled chicken, shrimp, or roasted vegetables
- Use it as a lighter alternative to pasta dishes
Because it absorbs flavor well, it works beautifully as a base rather than the main attraction.
Storage, Meal Prep & Reheating Tips
Cooked spaghetti squash stores well, making it ideal for planning ahead.
- Store leftovers in an airtight container for up to 4 days
- Reheat gently in a skillet or microwave
- Avoid adding sauce before storing to prevent sogginess
If you plan to freeze it, drain excess moisture first and reheat directly from frozen for best results.
Common Mistakes to Avoid
This section is often overlooked, but avoiding these mistakes makes all the difference:
- Adding too much water (leads to watery squash)
- Overcooking, which causes mushy strands
- Skipping the trivet and submerging the squash
- Shredding immediately without resting
Small adjustments here lead to consistently better texture.

Notes
- Whole squash option: You can cook the squash whole, but cooking time increases and texture is softer. Halving gives better control.
- Avoid sogginess: Do not add extra water beyond 1 cup.
- Texture control: Shorter release = firmer strands; longer release = softer strands.
