Ingredients

Scale
  • 4 cups grated zucchini (about 3.5 medium zucchinis)
  • ½ teaspoon salt
  • ½ cup finely chopped onion
  • 1 tablespoon minced garlic (about 3 cloves)
  • 2 large eggs
  • ½ cup grated Parmesan cheese (plus 2 tablespoons for topping)
  • 1 cup shredded mozzarella cheese
  • ½ cup shredded cheddar cheese
  • ½ cup Panko breadcrumbs
  • 2 tablespoons melted salted butter

Instructions

1. Prepare the Zucchini

  • Grate the zucchini and place it in a colander.
  • Sprinkle ½ teaspoon of salt over the zucchini and let it sit for 15 minutes to draw out excess moisture.
  • After 15 minutes, press the zucchini with a paper towel or clean cloth to remove any remaining liquid.

2. Combine the Ingredients

  • In a large mixing bowl, combine:
    • Grated zucchini
    • Chopped onion
    • Minced garlic
    • Eggs
  • Stir thoroughly to mix everything evenly.

3. Add the Cheeses

  • Mix in the Parmesan, mozzarella, and cheddar cheeses, stirring until well combined.

4. Assemble the Casserole

  • Lightly grease a baking dish with olive oil or cooking spray.
  • Spread the zucchini mixture evenly in the dish, pressing it down with a spatula.

5. Prepare the Topping

  • In a small bowl, mix together:
    • Panko breadcrumbs
    • Melted butter
    • 2 tablespoons Parmesan cheese
  • Stir until the breadcrumbs are evenly coated.

6. Bake the Casserole

  • Sprinkle the breadcrumb mixture evenly over the zucchini layer.
  • Preheat oven to 375°F (190°C).
  • Bake for 25-30 minutes or until the top is golden brown and crispy.

7. Serve & Enjoy

  • Let the casserole cool for a few minutes before slicing.
  • Serve warm as a side dish, appetizer, or light meal.

Notes

  • For a gluten-free version, replace Panko breadcrumbs with gluten-free breadcrumbs or almond flour.
  • To make it extra crispy, broil for the last 3-4 minutes of baking.
  • Add chopped spinach, mushrooms, or bell peppers for extra flavor.
  • Store leftovers in an airtight container in the fridge for up to 4 days.
  • Reheat in the oven at 350°F (175°C) for 10 minutes to restore crispiness.
