This zucchini casserole is an easy mixture of sliced zucchini with tomato sauce and bacon. A butter cracker and Parmesan cheese topping is the perfect finishing touch. Use diced tomatoes or crushed tomatoes in the dish instead of sauce, if desired.

The casserole is an excellent way to use fresh garden zucchini, and it goes well with just about any main dish. It also makes a great holiday side dish.


  • Butter, for greasing

  • 6 slices bacon, diced

  • 1 large yellow onion, chopped

  • 4 to 5 cups sliced zucchini

  5. Turn the zucchini mixture into the prepared 2-quart casserole

  6. In a bowl, toss the crushed crackers with the melted butter.

  7.  Sprinkle the buttered cracker crumbs and Parmesan cheese over the casserole.
