Choosing and Preparing Your Spaghetti Squash

Start with a firm, medium-sized spaghetti squash that feels heavy for its size. The skin should be hard and free of soft spots or bruises. A squash weighing about 3 to 4 pounds is ideal for most recipes.

Before cooking, wash the squash thoroughly. Use a sharp knife to cut it in half lengthwise. This can be challenging because of the tough skin, so take your time and use a sturdy cutting board. Scoop out the seeds and stringy pulp with a spoon. You can save the seeds for roasting later if you like.

Roasting Spaghetti Squash for Best Flavor and Texture

Roasting is the most popular way to cook spaghetti squash because it enhances the natural sweetness and gives a slightly nutty flavor.

Steps for Roasting

• Preheat your oven to 400°F (200°C).

• Cut the squash in half lengthwise and remove seeds.

• Brush the cut sides with olive oil and sprinkle with salt and pepper.

• Place the halves cut side down on a baking sheet lined with parchment paper.

• Roast for 40 to 50 minutes, depending on size. The flesh should be tender and easily pierced with a fork.

• Let it cool for a few minutes, then use a fork to scrape the flesh into spaghetti-like strands.

  
  

Roasted spaghetti squash pairs well with tomato sauce, garlic butter, or a sprinkle of Parmesan cheese.

Microwaving Spaghetti Squash for Quick Cooking

If you’re short on time, microwaving is a fast and effective method.

How to Microwave

• Pierce the whole squash several times with a fork to allow steam to escape.

• Place the squash in a microwave-safe dish.

• Microwave on high for 10 to 12 minutes, turning halfway through.

• Check for tenderness by poking with a fork. If it’s still firm, microwave in 2-minute increments.

• Let it cool slightly, then cut in half and scoop out the strands.

  
  

Microwaving keeps the squash moist but may result in a milder flavor compared to roasting.

Boiling Spaghetti Squash for Soft Texture

Boiling is less common but useful if you want very soft strands for soups or casseroles.

Boiling Instructions

• Cut the squash in half and remove seeds.

• Bring a large pot of salted water to a boil.

• Submerge the squash halves cut side down.

• Boil for 20 to 30 minutes until the flesh is tender.

• Drain and let cool before scraping out the strands.

  
  

Boiled spaghetti squash absorbs sauces well but can be watery, so drain thoroughly.

Tips for Perfect Spaghetti Squash Every Time

• Don’t overcook: Overcooked squash becomes mushy and loses its noodle-like texture.

• Use a fork to test doneness: The flesh should separate easily into strands.

• Season after cooking: Add salt, pepper, herbs, or sauces once the squash is cooked to keep the texture intact.

• Save the seeds: Roast them with olive oil and spices for a crunchy snack.

• Store leftovers properly: Keep cooked squash in an airtight container in the fridge for up to 5 days.
