Ingredients
For the Casserole:
- 4 cups shredded zucchini about 3–4 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
For the Topping:
- ½ cup panko breadcrumbs or gluten-free alternative
- 2 tablespoons melted butter
- 2 tablespoons grated Parmesan cheese
Instructions
- Prep the Oven & Dish: Preheat your oven to 375°F (190°C). Grease a 1 ½-quart baking dish to prevent sticking.
- Remove Excess Water from Zucchini: Place shredded zucchini in a colander and sprinkle with salt. Let it sit for 10 minutes to draw out excess moisture. Use a dish towel to squeeze out as much liquid as possible. This prevents a watery casserole.
- Mix the Casserole Base: In a large mixing bowl, combine zucchini, onion, garlic, eggs, Parmesan, mozzarella, and cheddar cheese. Mix well and spread evenly into the prepared baking dish.
- Bake the Casserole: Bake uncovered for 20 minutes to help set the mixture.
- Prepare the Crunchy Topping: In a small bowl, mix breadcrumbs, melted butter, and Parmesan cheese. Stir until the crumbs are evenly coated.
- Add the Topping & Finish Baking: Remove the casserole from the oven and sprinkle the buttered breadcrumbs over the top. Return to the oven and bake for another 5–10 minutes, until golden brown and crispy.
- Serve & Enjoy: Let the casserole cool slightly before serving. Pair it with a fresh salad or grilled protein for a complete meal!
