Easiest Way to Cook Spaghetti Squash!

  • Enjoy spaghetti squash as a low-carb alternative to pasta, by running a fork in the same direction as the strands to create ‘noodles.’
Ingredients to make microwave spaghetti squash including spaghetti squash, salt, pepper, and water

Only 5 Ingredients

Spaghetti Squash: Look for squashes that are clean and heavy with unblemished skins. Butternut and acorn squash can be microwaved, too!

Seasonings: Experiment with new flavors like a savory Italian seasoning, or a zesty Cajun flavor.

Protein Packed Snack

Don’t toss those spaghetti squash seeds! Roast them for a nutritious grab and go snack!

  • Simply rinse, pat dry, and roast them at 375°F for 15 minutes.
  • Lower the heat to 350°F.
  • Toss the seeds with a little olive oil and salt, and bake until they are golden brown.

How to Microwave Spaghetti Squash

  1. Prepare the spaghetti squash by poking holes around the squash with a fork in a line lengthwise (for easier cutting in half) and microwaving it for 3 minutes to soften it.
  2. Cut squash in half lengthwise and scrape out the seeds.
  3. Add water to a glass baking dish then place squash, cut side down, in the dish. Cover with plastic wrap.
  4. Cook until fork tender (as per the recipe below).
  5. Scrape with a fork to make noodles or cut into slices or cubes and season with sweet or savory herbs and spices!

Tips for Microwaving Squash

  • Do not try to cook a whole squash all of the way in the microwave, steam buildup can cause it to burst open.
  • Avoid adding too much water as it will make the squash mushy and the strands won’t be as long as they could be.
