Zucchini-Onion Casserole Recipe

I came up with this dish by downsizing my recipe for a crowd. I experimented with amounts, adding and deleting until I got it just right. This is a great side dish that goes well with any meat.
TOTAL TIME: Prep: 15 min. Bake: 25 min. YIELD:2 servings


  • 1-1/3 cups sliced zucchini
  • 3/4 cup water
  • 1 medium onion, chopped
  • 1 tablespoon chopped green pepper
  • 1 egg
  • 1/2 cup mayonnaise*
  • 1/3 cup grated Parmesan cheese
  • 1/4 teaspoon salt
  • 1/8 teaspoon pepper
  • 1/3 cup crushed butter-flavored crackers (about 8 crackers)


  • 1. In a saucepan, combine the zucchini, water, onion and green pepper; bring to a boil. Reduce heat. Cover and simmer for 5 minutes or until vegetables are crisp-tender; drain.
  • 2. In a bowl, beat the egg. Add mayonnaise, Parmesan cheese, salt and pepper; mix well. Stir into vegetable mixture. Transfer to a greased 1-qt. baking dish; sprinkle with cracker crumbs. Bake, uncovered, at 350° for 25-30 minutes or until golden brown. Yield: 2 servings.

"This was super easy. I was leery because of the ingredients what this would turn out to be, but it was really tasty. It has an almost quiche like consistency."
