Zucchini & Caramelized Onion Quiche

No, your eyes aren’t deceiving you. This may look like my Italian Zucchini Crescent Pie, but instead it’s Zucchini & Caramelized Onion Quiche! Since my recent turn from a zucchini hater to a zucchini lover, I’m cooking it all the time now. Usually I cut it into big chunks and roast it in my oven with other veggies, but thanks to these two recipes, I’ve learned it cooperates very nicely in quiche form. Thin slices with that pretty green edge make for an equally good-looking dish, too.

So, how’s it taste?

Gosh this was so good! I’m a sucker for quiche anyway and this one has a layer of caramelized onions at the bottom that I just loved. Slowly cooked, sweet onions are awesome. I used skim milk instead of 1% and it worked great. However, I do think three cloves of garlic was too much. I’ll reduce it down to two cloves next time. I also liked how one serving was a sixth of the quiche. Sometimes with these low calorie quiche recipes, they’ll be eight servings, which is too small. A slice of this quiche was pretty satisfying for a light lunch.
