How to Cook Spa Squash. It is literally one of my favorite veggies year round. It is delicious, filling and it makes a great low carb substitute for pasta dishes or in soups! Just a little bit of butter or olive oil and salt & pepper turns it into a simple side.

Tender spaghetti squash made easy in the microwave.


  • 1 spaghetti squash
  • 1/4 cup water
  • 2 tablespoons butter optional
  • salt & pepper to taste


  • Pierce spaghetti squash with a fork about 8 times. Place in the microwave 3-4 minutes (do not cook longer than 5 minutes whole).
  • Remove the squash from the microwave and slice from top to bottom lengthwise. Using a spoon, remove seeds and pulp and discard.
  • Place 1/4 cup water in the bottom of a small casserole dish. Add squash cut side down. Cover tightly with plastic wrap.
  • Microwave 6-10 minutes or until the squash is easily pierced through the skin with a fork.
  • Remove from microwave, carefully remove plastic wrap (hot steam will escape so use caution).  
  • Gently run a fork from top to bottom creating strands of spaghetti squash. Season with butter, salt and pepper.

Recipe Notes

A medium to small spaghetti squash takes about 7 minutes in my microwave. This can vary based on squash size and microwave wattage.
