Laura’s Tips for Cooking Spaghetti Squash in the Microwave
After 15 to 20 minutes on high, your squash should be soft and tender, but not all squash are the same, so check doneness by poking with a fork. If there’s very little resistance and the skin is soft, then it’s cooked.
The microwave is notorious for trapping steam when cooking spaghetti squash because it cooks for a long time inside. To keep it from getting soggy, open the microwave door a few times during the cooking process, and once it’s finished cooking, use a paper towel to absorb the excess moisture before shredding it with a fork.
Yes! You can reheat cooked spaghetti squash in the microwave as you would do with pasta, no sticking risk! Warm it up for about one minute, stir, and keep microwaving until it’s heated through.
What to Serve with This Side
One of my favorite main dishes to serve with spaghetti squash is garlic butter chicken. If you ask my kids, they tell you these spaghetti squash lasagna boats can’t be beaten. It’s also a great side for baked salmon, pork loin roast, or meatballs.

Prep:

- On a flat surface, carefully slice it lengthwise. With a spoon, scrape the seeds out and discard. Pierce the skin of the squash with a sharp knife -this helps the heat go through the squash layers.
- Place one-half of the squash into a microwaveable-safe dish that is a few inches deep. Then, top it with the other half. Fill the bottom of the dish with water, about half an inch.
Microwave:
- Microwave the spaghetti squash for 15 to 20 minutes, or until the skin is soft and you can poke it with a fork with little resistance. Opening the microwave at the 10-minute mark to let some of the steam out and carefully swap the positions of the spaghetti squash. Remove from the microwave.
Serve:
- When ready to serve, remove the squash from the dish onto a cutting board, and with a fork, separate the squash shreds from the skin and transfer them onto a plate. Top it with your favorite sauces or use it in a recipe.
