Zucchini and Onion Gratin

One of my favorite side dishes.  Easy to make and tastes good hot or warm.  The tomato/onion mixture blends nicely with the zucchini.  I even had some leftovers for breakfast.  Yummy!!

Even DH who normally complains when I cook zucchini said it was yummy.  Definitely a keeper here.

Made this exactly as written and turned out wonderful. The Onions had the best flavor. Very easy dish to prepare ahead also.

I'm tired of grilled zucchini and this was a great recipe for a change.

instead of tomato sauce used a can of tomatoes which delivered more flavour. added some garlic too.

Love this recipe. Added 2 sliced tomatoes sliced when broiled the zucchini. And a layer of extra parmesan cheese. The onion base seems dry but the liquid from the veggies loosens the tomato bases to a lovely sauce. Really great

Dee-licious! Next time I'm going to double the onion mixture, layering it on top before adding the cheese. I know the calorie count will increase, but I don't care!!!!!

This was excellent! It went together quickly and easily and was extremely tasty. I used the leftovers for filling in a quesadilla for lunch the next day. Yummy! I'll definitely hold on to this one for when my garden is exploding with zucchini in a few weeks.

Loved this side dish. I am always looking for new ways with zucchini and this was perfect. The only change I made was to grill the zucchini--everything else I did as written.
