This is a mouth-watering way to use up some of your zucchini bounty. If you didn't grow any zucchini this year, it will be worth going to the store to pick some up! I came up with this recipe the year I planted four zucchini plants...and the zucchini couldn't grow fast enough for our family! Every time there was one big enough, we made this recipe! :D And yes, the garlic amount is correct...a head, not a clove. It's very garlicky, but the garlic softens and mellows in texture and flavor. I've actually had the garlic melt (for lack of a better phrase) when baked long enough.
