This zucchini gratin is layers of tender sauteed zucchini and cheese in a creamy sauce, topped with breadcrumbs and baked to perfection. A simple yet elegant side dish!
If you like zucchini, you’ll love this easy, cheesy and flavorful recipe. This is my absolute favorite way to eat zucchini.
It is almost summer, and soon everyone’s gardens will be overflowing with zucchini and summer squash! When I have zucchini on hand, I often use it in this amazingly delicious zucchini gratin. The flavors and textures just can’t be beat!
How do you make zucchini gratin?
This dish has a couple of components – the vegetables, the cheese and the sauce. The first step is to saute zucchini and onions in butter. You want your zucchini to be crisp tender, be careful not to over cook it as it will continue to cook in the oven.
After the zucchini is cooked, it gets layered in a baking dish with plenty of creamy sauce and shredded cheese. I typically use Monterey Jack or mozzarella cheese here, but other great options are cheddar or fontina.
The final step is more sauce and a sprinkling of seasoned breadcrumbs before the gratin goes into the oven.
Bake until golden brown, then serve up your zucchini gratin and watch the compliments come in!
How do you cook zucchini?
You can actually cook the zucchini for this recipe any way you like – I personally prefer sauteeing the zucchini because I think it’s the most flavorful method. That being said, steamed or roasted zucchini would also work well in this recipe.
Is zucchini good for you?
Zucchini has a lot of nutritional benefits! It’s low calorie and packed with antioxidants, and vitamins B and C. It’s also a great source of potassium.
I love to serve this zucchini gratin as a side dish to grilled meats and seafood. Try it alongside a roasted chicken or baked salmon for an easy yet satisfying meal. You’ll never look at zucchini the same way again!
