Preheat oven to 400 degrees. Lightly spray a 2-quart casserole dish with cooking spray and set aside.
In a small saucepan, melt 2 Tablespoons of butter over medium heat, and whisk in the flour, salt, and pepper. Add the whipping cream and stir for about 2 minutes until it thickens. Add ¼ cup parmesan cheese.
Arrange half of the zucchini in the prepared casserole dish overlapping each other. Spread half of the sauce on top, followed by ½ cup mozzarella cheese and ½ cup Gruyere cheese. Repeat with another layer of zucchini and sauce.
Top with the remaining mozzarella cheese and parmesan cheese.
Bake for 25 minutes or until the zucchini is fork tender and the top starts to brown. Sprinkle with chives before serving.
