Preheat the oven to 350°F. Butter a 1 1/2 quart gratin or casserole dish.
Put the diced zucchini in a large microwave safe bowl and microwave on high for about 4-5 minutes, stirring to rearrange the zucchini twice during cooking. Drain the zucchini in a mesh strainer to remove any excess moisture and set aside.
Toss the topping ingredients together in a small bowl, mixing until the butter is evenly dispersed and everything is evenly mixed. Set aside.
Whisk together the remaining casserole ingredients to combine well.
Fold in the zucchini and turn into your prepared casserole dish.
Sprinkle the topping evenly over the casserole and bake for about 45 minutes, or until the casserole is bubbling and the topping is golden. Serve immediately.
