Ingredients & Equipment

Ingredients

4 medium zucchini, thinly sliced
1 cup shredded cheddar cheese
1/2 cup shredded mozzarella cheese
1/2 cup grated Parmesan cheese
1 small onion, finely diced
2 cloves garlic, minced
1/2 cup breadcrumbs (plain or seasoned)
1/2 teaspoon salt
1/4 teaspoon black pepper
1/4 teaspoon paprika (optional)
1/2 cup milk (dairy or plant-based)
2 tablespoons butter, melted
2 tablespoons olive oil
Fresh parsley, chopped, for garnish

Equipment

9×13-inch baking dish
Large mixing bowl
Knife and cutting board
Measuring cups and spoons
Wooden spoon or spatula
Skillet for sautéing onions and garlic

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with olive oil or butter to prevent sticking and ensure easy serving.

Step 2: Prepare the Zucchini

Wash the zucchini and slice thinly, about 1/4-inch thick. Pat slices dry with paper towels to remove excess moisture—this helps prevent a watery casserole.

Step 3: Sauté Aromatics

In a skillet, heat olive oil over medium heat. Add diced onion and minced garlic, sautéing for 3–4 minutes until softened and fragrant. Cooking these aromatics first enhances the flavor of the casserole and distributes the flavors evenly.

Step 4: Combine Ingredients

In a large mixing bowl, combine zucchini slices, sautéed onion and garlic, cheddar cheese, mozzarella cheese, milk, salt, black pepper, and paprika. Mix gently to ensure the zucchini is evenly coated with the cheese and milk. This forms a creamy base for the casserole.

Step 5: Assemble the Casserole

Pour the zucchini mixture into the prepared baking dish, spreading it evenly. In a small bowl, mix breadcrumbs with melted butter and Parmesan cheese. Sprinkle the breadcrumb mixture over the top of the casserole. This will create a golden, crunchy topping that contrasts beautifully with the creamy zucchini beneath.

Step 6: Bake

Bake in the preheated oven for 30–35 minutes, or until the cheese is melted, the topping is golden brown, and the zucchini is tender. To test doneness, insert a fork into the casserole; it should go through easily without resistance.

Step 7: Rest and Serve

Allow the casserole to cool for 5 minutes before serving. Garnish with fresh parsley for a pop of color and freshness. Serve as a side dish or a vegetarian main, pairing with a simple salad, roasted vegetables, or grains like quinoa or rice.

Expert Tips & Troubleshooting

Prevent sogginess: Pat zucchini slices dry and avoid overcrowding the baking dish. Excess moisture can make the casserole watery.
Cheese alternatives: Feel free to try Gruyère, Monterey Jack, or a blend of your favorite cheeses for different flavors.
Add more vegetables: Bell peppers, spinach, or mushrooms can add extra flavor, texture, and nutrition.
Breadcrumb crunch: Mix in garlic powder or Italian seasoning for added flavor and aroma.
Leftover storage: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven to maintain the crunchy topping.

Variations & Customizations

Low-carb option: Use almond flour or crushed nuts for the topping instead of breadcrumbs.
Spicy twist: Add a pinch of red pepper flakes or diced jalapeños to the zucchini mixture.
Herb boost: Fresh basil, thyme, or oregano can enhance the flavor and add an aromatic touch.
Protein addition: Stir in cooked chicken or turkey for a heartier dish suitable for dinner.
Vegan version: Substitute dairy cheeses with plant-based alternatives and use non-dairy milk.

Serving & Presentation Ideas

Serve alongside grilled chicken, fish, or roasted tofu for a complete meal.
Pair with a crisp green salad dressed with lemon vinaigrette for a light contrast.
Garnish with freshly chopped parsley or basil to make the dish visually appealing.
Serve family-style directly from the baking dish for a cozy, inviting presentation.
Drizzle a little extra olive oil or a squeeze of lemon over the top before serving to brighten flavors.

Storage & Make-Ahead Tips

Refrigeration: Store cooled casserole in an airtight container for up to 3 days. Reheat in the oven at 350°F (175°C) to maintain the crunchy topping.
Freezing: Assemble the casserole without baking and freeze for up to 2 months. Thaw in the fridge overnight and bake as directed.
Make-ahead prep: Prepare zucchini slices, sauté onions and garlic, and mix ingredients ahead of time. Assemble the casserole just before baking.
