How Long Does It Take To Cook Spaghetti Squash?

Cooking spaghetti squash can vary in time depending on the method you choose. If you opt to bake it in the oven, preheat the oven to 400°F and cut the squash in half lengthwise, removing the seeds. Place the halves cut-side down on a baking sheet lined with parchment paper. Bake for about 40 to 50 minutes, or until the flesh is tender and easily shredded with a fork. For microwaving, cut the squash in half and remove the seeds, then place the halves cut-side down in a microwave-safe dish with a bit of water. Microwave on high for about 10 to 12 minutes, checking for doneness. Alternatively, you can use an Instant Pot by placing a whole spaghetti squash on the trivet with a cup of water. Cook on high pressure for 15 to 20 minutes, then let the pressure release naturally for 10 minutes before quick-releasing any remaining pressure. The squash should be tender, allowing you to easily shred the flesh into spaghetti-like strands. Depending on your preference for texture and convenience, each method offers a slightly different cooking time but yields a delicious, versatile base for various dishes.

Preparing spaghetti squash before cooking

When preparing spaghetti squash, each cooking technique requires a slightly different approach. The method you choose ultimately depends on your personal preference. Are you drawn to the deeper, nuttier taste that roasting brings out in vegetables, or do you lean towards steaming your squash?

For most cooking methods, it's advisable to slice the squash in half across its width rather than lengthwise. This not only makes it easier to cut but also yields longer, pasta-like strands, which is why it's called "spaghetti" squash. If you're roasting it in the oven, remove the seeds (you can save them for roasting later), season with salt and pepper, and place it cut side down. When steaming spaghetti squash in the microwave, be sure to score the flesh before seasoning and place it cut side down in a shallow dish filled with water. If you're using an Instant Pot, there's no need to cut the squash in half; simply pierce it all over with a knife and add a cup of water.

Finding the right cooking time

Since no two spaghetti squashes are identical, the cooking time in your oven (or Instant Pot) will vary slightly. Each squash will differ in weight, shape, moisture level, and ripeness, but with a bit of patience and careful observation, you'll master the art of cooking it to perfection every time.

When baking, spaghetti squash usually requires about an hour at 350 degrees Fahrenheit. In contrast, steaming it in the microwave—similar to cooking a potato—takes only 5-10 minutes on high power. Ultimately, numerous factors can influence how the spaghetti squash cooks, so your attention is crucial for achieving the desired results. Check the squash for knife tenderness, use a fork to see how easily the flesh can be scraped, and don’t forget to taste it. If the texture isn’t quite right, simply cook it a bit longer and test again. After a few attempts, you’ll find the ideal texture for your spaghetti squash, tailored to your preferences and the size of the squash.
