This step-by-step guide tells you how to microwave spaghetti squash, how to tell when it’s fully cooked, and how to scoop out the seeds.


  • Spaghetti squash
  • Water


  1. Carefully cut the squash in half lengthwise with a large chef’s knife. Break it apart at the stem.
  2. Open the squash and scoop out the seeds and pulp.
  3. Place the squash halves, cut side down, in a large microwave safe casserole dish. (I used a 9 by 13-inch pyrex lasagna dish.) Pour 1 cup tap water over the squash.
  4. Layer parchment or wax paper over the squash. Then cover with plastic wrap.
  5. Microwave the squash until it is done. To be safe, microwave the squash in 5-minute intervals (smaller squash will cook faster, while larger squash might need up to 15+ minutes). If you can’t tell if your squash is done, see my notes in the post above for tips on testing the doneness of the squash.
