Personally, I prefer roasting  spaghetti squash in the oven. But many asked me how to cook it in the microwave without going through the hardship of cutting through its skin. Here is now: * Poke many hols in the skin with a fork, or make small cuts all around with a knife, then place in a microwave safe dish. * Microwave on medium-high ( I would say 70% power) for 5 minutes. * Rotate the squash and microwave again for another 5 minutes. * Repeat rotating and microwaving until it is done , time depends on the size of your squash. * Let it set for 10 minutes, cut, scoop the seeds out and proceed with the recipe as is.
