Staple Ingredients for Squash

  • Squash: Look for heavy squash that is golden in color and free from blemishes.
  • Butter: Butter makes everything better, and spaghetti squash is no exception. The mild flavor of squash is perfectly complemented by melted butter.
  • Seasonings: Simple salt and black pepper are all that is needed for a perfect, simple flavor every time.

Savory Swaps

Replace the butter with bacon grease for a smoky flavor.

Sprinkle the squash with some Parmesan cheese or herb and garlic seasoning.

Brush on some hot sauce or salad dressing to add instant flavor to spaghetti squash.

How to Cook Spaghetti Squash in the Microwave

  1. Cut the spaghetti squash vertically from top to bottom and scoop out the seeds.
  2. Place half of the squash, cut side down, in a casserole dish with water.
  3. Cover with plastic wrap and cook (full recipe below).
  4. Remove the squash from the microwave and run a fork over the flesh to separate the strands.
  5. Season with butter, salt, and pepper before serving.

Handy Hints

  • Don’t cook spaghetti squash whole, it cooks better and is easier to handle when halved. If it’s tough to cut, poke it with a fork and microwave for 3-4 minutes first.
  • The best way to check for doneness is to pierce the outer skin with a fork. It should be soft.
  • When the squash is cooked, flip it over and start shredding the flesh, or it may become overcooked.

Leftover Squash?

Keep leftover microwave spaghetti squash in a covered container in the refrigerator for up to 4 days, and in the freezer for up to 6 months.

Use leftover spaghetti squash in spaghetti tacos, or use it instead of macaroni in a hearty minestrone. Don’t forget to rinse, dry, and season spaghetti squash seeds and toast them in the oven for a healthy snack, just like these roasted pumpkin seeds!

Ways to Use Spaghetti Squash

Use spaghetti squash instead of pasta in your favorite recipes for a healthy twist.
