Do I need to peel yellow squash?
Almost never. Like zucchini, a yellow squash is a summer squash that's picked while immature, and has a delicate, edible rind. Its thin skin and high water content allow it to cook up quickly, whether grilled, steamed, baked, sautéed or deep-fried.
Occasionally, you'll run across an especially bumby crookneck squash, which you might need to whittle down. Otherwise, you're all set.
