Servings
Ingredients
- 4 cups grated zucchini approximately 3.5 medium zucchinis
- ½ teaspoon salt
- ½ cup finely diced onion
- 1 tablespoon minced garlic
- 2 large eggs
- ½ cup grated Parmesan cheese plus an additional 2 tablespoons for topping
- 1 cup shredded mozzarella cheese
- ½ cup shredded cheddar cheese
- ½ cup Panko breadcrumbs
- 2 tablespoons melted butter
Instructions
Prepare the Zucchini
- Begin by placing the grated zucchini in a colander. Sprinkle it with ½ teaspoon salt and allow it to sit for 10 minutes to draw out excess moisture. Afterward, use a clean kitchen towel to squeeze out as much liquid as possible. This step is essential to prevent a watery casserole.
Preheat the Oven
- Preheat the oven to 375°F (190°C) and lightly grease a small baking dish with cooking spray to prevent sticking.
Mix the Ingredients
- In the prepared baking dish, combine the drained zucchini, diced onion, minced garlic, eggs, ½ cup Parmesan cheese, mozzarella cheese, and cheddar cheese. Mix until well combined, then spread the mixture evenly into the dish.
Bake the Casserole
- Place the dish in the preheated oven and bake uncovered for 20 minutes to allow the cheese to melt and the zucchini to soften.
Prepare the Topping
- While the casserole bakes, prepare the topping by combining Panko breadcrumbs, melted butter, and the remaining 2 tablespoons of Parmesan cheese in a small bowl. Stir until evenly coated.
Add the Topping & Continue Baking
- After 20 minutes, remove the casserole from the oven. Evenly sprinkle the prepared breadcrumb mixture over the top. Return the dish to the oven and bake for an additional 5 to 10 minutes until the topping becomes golden brown and crisp.
Rest & Serve
- Allow the casserole to rest for a few minutes before serving. This allows the flavors to meld and the texture to set properly. Serve warm as a flavorful side dish alongside your favorite main course.
