Spaghetti Squash has been referred to as the noodle squash. It is a winter vegetable that is oblong in shape and is yellow. It has a hard outer rind and is medium size.

How to Cut a Spaghetti Squash:

The best way to cut a spaghetti squash is right down the middle. It will take a sharp chef’s knife and a cutting board to cut it. Be careful as the skin on the squash is very tough.

There are two ways to cut the squash, widthwise or lengthwise. We usually cut lengthwise as it easier to cut. It all depends on the size of strands you want.

Once it is cut in half then you can start removing the seeds and squash strands so you can begin cooking.
