Parmesan Zucchini Squares Recipe

I noticed that two women submitted the exact same recipe called zucchini appetizers in my North Carolina State Elks Association Cook Book, and we always have too many zucchini in the middle of garden season. So I grabbed a couple and got a pan of Parmesan Zucchini Squares baking in the oven.

The aroma that comes from the oven while these are baking is heavenly. It comes from the combination of dried oregano and parsley, and also the  garlic powder and minced fresh garlic.

The herbs, garlic and Parmesan cheese bring the flavor while the zucchini creates a nice texture. I love it, and it’s safe to say that it will be a regular on our summer menu.

If you’ve never used a baking mix like Bisquick, then I recommend getting a box to keep on hand. You can make a quick biscuit or pancake, or it makes a great base for breads like this Parmesan Herb Zucchini bread.

For the Parmesan Cheese in these Parmesan Zucchini Squares, just go ahead and use the cheap parmesan cheese in the green jar. You know the one. Your kids probably sprinkle it on top of spaghetti.
