Every summer when the zucchini are ready to be picked out of the garden, I pull out all my favorite zucchini recipes, including this Chicken & Zucchini Casserole recipe. With just 7 ingredients, it is one of my favorite weeknight dinner recipes. Best of all, it takes less than 10 minutes to prepare. Then throw it in the oven and in an hour a complete and delicious dinner is ready to be served.
