Cut the spaghetti squash in half lengthwise and scoop out the seeds. Season with salt and pepper lightly.
Place both halves in a microwave-safe dish, cut side down. If both halves don't fit in your microwave plate, cook them separately.
Microwave on high for 7-12 minutes or until fork-tender. The time will vary depending on the size of your squash.
Let it cool, then scrape the squash into strands. Serve in your favorite way!
Notes
Ensure even cooking by placing squash halves cut sides down in a microwave-safe dish and cover with a microwave-safe lid or wrap to trap steam. This will help speed up the cooking process.
