    Are you wondering what to make with all that fresh zucchini and fresh yellow squash that seems to be available every year? They grow easily and are commonly found in many people's summertime gardens. This delicious zucchini gratin is something the whole family and even picky eaters will enjoy.

    This easy zucchini casserole would go perfectly served alongside pork chops or chicken coated with this Homemade Shake and Bake (copycat) Recipe.

    Ingredients needed

    You can make this effortless cheesy squash side dish with these simple ingredients. Plus, you can easily switch up the ingredients, like the type of squash, cheese, or the seasoning used, to make this recipe work perfectly for your family.

    Ingredients shown, and labeled for zucchini gratin.
    • Zucchini - I used two medium zucchinis.
    • Yellow Squash - I used one large yellow squash.

    • Panko Crumbs - Just plain panko crumbs.
    • Olive Oil
    • Salt
    • Black Pepper

    How to make this easy recipe

    Preheat the oven to 425 degrees F.

    Wash, drain, and dry off the squash.

    If you are not using shredded cheese already, shred some now. You will need 4 - 6 ounces, depending on your taste.

    Place the squash mixture in the oven and bake for 15 minutes. Remove from the oven.

    Helpful hint

    I know that heating up the oven in the summertime can be dreadful. When I baked this cheesy squash pictured above, I used my countertop 10-in-1 unit. It worked perfectly since this isn't a huge casserole dish. I still baked it at 425 degrees F and for the time noted in the recipe.

    Substitutions

    • If you prefer, use all zucchini or all yellow squash.
    • Instead of garlic seasoning, use Italian seasoning.
    • Use your favorite type of cheese. I know kids usually prefer cheddar cheese. Adding a little bit of Parmesan cheese would be great too!
    • Instead of panko, use crushed Ritz crackers.

    This recipe is perfect for

    Fix this simple zucchini casserole for

    • A summertime side dish.
    • A side dish served at a BBQ or get-together.
    • Since your local grocery store probably carries squash year-round, this would also make a perfect side dish for Thanksgiving or Christmas.

    Store any leftovers in a covered dish in the refrigerator. We usually heat up any leftovers in the microwave oven.

      I make a version of this all the time with an addition of chopped fresh tomatoes and fresh garlic. Everyone loves it and it's so good for you.
