A great way to use-up all that extra zucchini this summer!
Baked Zucchini Gratin
1 onion, sliced
2 lb. zucchini, sliced
1/2 c. butter, melted
2 c. shredded mozzarella cheese
1/2 c. cracker crumbs
1/4 c. grated Parmesan cheese
Saute the onion in a little olive oil until tender.
Layer the zucchini and onions into a greased 2-quart dish. Drizzle with half of the butter; sprinkle with mozzarella cheese.
In a separate bowl, combine remaining butter, cracker crumbs and Parmesan cheese. Sprinkle crumb mixture evenly over top.
Bake, uncovered at 350 for 35-40 minutes, or until zucchini is tender.
