This type of squash changes the weeknight dinner game. Will and I love picking one up, slicing it open, and throwing together some type of filling while it’s cooking in the oven.

How to Cook Spaghetti Squash in the Oven

There are a few different ways to make spaghetti squash in the oven. I prefer to slice it in half lengthwise, remove the seeds (discard or roast), and then rub each half with a little olive oil, salt, and pepper. Place the halves cut side down on a baking sheet lined with parchment.

You can also put the squash halves cut side down in a 9×13 baking dish (with sides) and fill the dish with ½-1″ of water. This will help “steam” the squash while it cooks.

Cook in the oven at 400 degrees F for 35-50 minutes. Cooking time will vary depending on the size of the squash.

Use an oven mitt to flip over each half to let the heat escape (spaghetti squash can be really hot)! Then use a fork to pull the strings away from the skin.

How to Cook Spaghetti Squash in the Microwave

Making spaghetti squash in the microwave is the best way to cook it fast! Here’s how to do it:

Slice the squash in half lengthwise and remove the seeds.
Place the squash cut side down in a small baking dish. Fill the dish with ~1″ of water.
Microwave on high for 10-12 minutes, or until you can pierce the skin with a fork.
Let the squash cook for a few minutes before you flip it over and remove the flesh.

Be sure to keep an eye on the squash while it’s cooking. Smaller squash will cook faster. Cooking times will also depend on the power of your microwave.

Can cooked spaghetti squash be frozen?

Cooked spaghetti squash can be frozen in airtight freezer bags or Stasher bags. Let the squash cool before transferring to bags, then squeeze out as much air as possible before sealing.
