Cheesy Zucchini Gratin is a great side dish for all of those upcoming summer BBQ’s and potluck parties! It’s full of fresh zucchini and sweet onions nestled a cheesy sauce that compliments just about anything you serve it with.

I love just about anything with the name “gratin”… Potato Gratin, Cauliflower Gratin, Sweet Onion Gratin. This recipe for Cheesy Zucchini Gratin is no exception. It’s really delicious and makes a wonderful side dish that goes with just about anything! According to Wikipedia, the French word “gratin” refers to the shallow ceramic dish that these recipes are normally baked in. Traditionally, gratin recipes include cheese, breadcrumbs, and butter and have a browned, crispy topping. I’ve gone a bit against tradition here and used an 8-inch x 8-inch baking dish to bake this in and used buttery crackers for the topping, instead of breadcrumbs, but the recipe is true to its name in every other sense!

This recipe is adapted from an Ina Garten recipe. I just love, love, love Ina, and her simple, yet utterly delicious, recipes and cooking style. I always know, when I start with an Ina recipe, the end result will be a successful one. She is especially adept at creating wonderful comfort foods like this one. I mean cheesy…who doesn’t find comfort in cheese?

It won’t be long before everyone’s gardens are overflowing with zucchini and even if you don’t have a garden, zucchini will soon be abundant and priced right in the grocery stores. Why not turn all that zucchini into something spectacular? This is a wonderful recipe and my family enjoyed it very much. I know it will show up on my table again and again. I think maybe the only way to make it better might be to add some bacon next time! What do you think?
