Ingredients

  • 3 cups thinly sliced zucchini
  • 1/2 cup Bisquick
  • 1/2 cup chopped onions
  • 1/2 cup grated cheese
  • 1/2 teaspoon salt
  • 1/2 cup vegetable oil
  • 1 clove garlic
  • 4 beaten eggs

Instructions

  1. Set aside 1/2 cup grated cheese for topping.
  2. Grease or spray a 13 x 9 x 2-inch baking dish or smaller for a thicker crust.
  3. Mix all ingredients except the reserved cheese and spread evenly in the prepared dish.
  4. Top with the reserved grated cheese.
  5. Bake for 30 to 35 minutes or until golden brown.

Tips & Substitutions

For a lighter version, consider using egg whites instead of whole eggs. If you don’t have Bisquick, you can substitute it with a homemade mixture of flour, baking powder, and salt. Adding fresh herbs like basil or oregano can elevate the flavor profile. For extra creaminess, mix in some cottage cheese or Greek yogurt. If you enjoy comforting baked goods, check out Mom'S Deep Dark Chocolate Cake for dessert.
