Patty pan squash could more accurately be called "flying saucer" squash because of its appearance—and, in fact, it sometimes is. Some say these little squashes look like Scottish tams. The patty pan is small, round and flat, with edges that resemble an alien spacecraft. It might be yellow, white, or green.
Its appearance aside, patty pan squash is versatile and makes for some delightful summer recipes. It can be grilled, fried, or, in this case, oven-roasted. Patty pans impart a somewhat buttery flavor, although some people think they taste more like olive oil.
