While testing zucchini recipes for my new e-book, 23 Zucchini: Fast, fun, easy recipes from The Perfect Pantry® kitchen, I tried some dishes that, although successful, didn't make the final cut, often because they were similar to other recipes in the book. My friend Ann first suggested I include a zucchini pie, and I read through many recipes before I stepped into the kitchen. I decided to make a pie that would hold up well for picnics and potlucks -- something a bit more sturdy than a traditional frittata or egg casserole -- and this version passes the test. It's important to squeeze as much water as you can out of the shredded zucchini before adding it to the egg batter (this short video I made for 23 Zucchini shows you an easy way to do it). If you don't, you'll end up with something more like pudding than pie. You can make this up to a day or two ahead.
