Ingredients
  • 4 cups grated zucchini I used about 3.5 medium zucchinis
  • ½ teaspoon salt
  • ½ cup finely diced onion I like to use frozen diced onion as a shortcut
  • 1 tablespoon minced garlic
  • 2 eggs
  • ½ cup grated Parmesan cheese plus an additional 2 tablespoons
  • 1 cup shredded mozzarella cheese
  • ½ cup shredded cheddar cheese
  • ½ cup Panko breadcrumbs
  • 2 tablespoons melted butter
Instructions
  1. Preheat oven to 375 degrees F. Spray a small baking dish with cooking spray and set aside (I used a dish that was 8-in x 5-in, but an 8-inch square pan will also work).
  2. Place zucchini in a colander, sprinkle with salt, and allow to sit for about 10 minutes (this will help draw out some of the water from the zucchini). After 10 minutes, squeeze out moisture from the zucchini. TIP: In order to make sure that I get most of the water out of the zucchini (and avoid a runny casserole), I like wrap the zucchini in a dish towel. Squeeze it and wring it out multiple times while it's in the towel -- you will be shocked by how much liquid comes out!
  3. In the prepared dish, combine zucchini, onion, garlic, eggs, ½ cup Parmesan cheese, mozzarella cheese, and cheddar cheese. I like to use my hands to make sure that it’s all completely combined, and then gently press the mixture evenly into the prepared dish.
  4. Bake uncovered for 20 minutes.
  5. Meanwhile, in a small bowl, pour melted butter over breadcrumbs and 2 tablespoons of Parmesan cheese. Stir until completely combined.
  6. After 20 minutes, remove zucchini from the oven. Sprinkle buttered breadcrumbs over the zucchini and return the dish to the oven. Continue baking for about 5-10 more minutes, or until the top is golden brown and crispy.
