Preparation Steps

Preheating the Oven

First, preheat your oven to 180°C (350°F). This ensures that it’s ready to bake the casserole evenly.

Preparing the Zucchini and Onion

Slice the zucchini and chop the onion. These will form the base layer of your casserole.

Layering the Casserole

Arranging Zucchini and Onion in the Baking Dish

In a baking dish, layer the sliced zucchini and chopped onion evenly. This layering ensures that every bite is flavorful.

Seasoning with Salt and Pepper

Season the zucchini and onion with salt and ground pepper to taste. This simple seasoning brings out the natural flavors of the vegetables.

Baking the Base

Initial Baking Process

Place the baking dish in the preheated oven and bake for 20 minutes. This initial baking softens the vegetables and prepares them for the next layers.

Preparing the Egg Mixture

Whisking Eggs with Spices

In a bowl, whisk together 4 beaten eggs, salt, ground pepper, and a dash of paprika. This mixture will add a rich, custardy texture to the casserole.

Adding the Egg Mixture

Pouring the Egg Mixture Over the Baked Vegetables

After the initial baking, pour the egg mixture over the baked zucchini and onion. Make sure the mixture spreads evenly.

Cheese and Oat Flake Topping

Adding Parmesan Cheese and Oat Flakes

Sprinkle grated Parmesan cheese and 2 tablespoons of oat flakes over the top. This adds a delicious crunch and rich flavor.

Sprinkling Chopped Parsley

Add a handful of chopped fresh parsley for a burst of freshness and color.

Mozzarella Cheese Layer

Topping with Grated Mozzarella

Finally, top the casserole with a generous amount of grated Mozzarella cheese. This creates a gooey, golden crust when baked.

Final Baking

Baking Until Golden Brown

Return the baking dish to the oven and bake for another 35 minutes, or until the top is golden brown and bubbly.

Preparing the Yogurt Sauce

Mixing Yogurt with Dill, Garlic, and Lemon Juice

In a small bowl, mix 3 tablespoons of yogurt with chopped fresh dill, minced garlic, and the juice of half a lemon. This sauce adds a refreshing tangy flavor that complements the casserole perfectly.
