Step-by-Step Cooking Directions
1. Prepare the Zucchini:
Grate the zucchini and sprinkle with salt. Let it sit for 10 minutes to draw out the moisture. Then, squeeze out as much liquid as possible using a clean kitchen towel or your hands.
2. Sauté the Vegetables:
In a pan, heat olive oil and sauté the chopped onion until translucent. Add the grated carrot, bell pepper, diced tomatoes, and sliced mushrooms. Season with salt, pepper, and basil. Cook on medium heat, stirring occasionally, until vegetables are tender, about 7–10 minutes. Set aside to cool slightly.
3. Prepare the Batter:
In a mixing bowl, whisk together eggs, milk, flour, baking powder, and a pinch of salt until smooth.
4. Combine and Layer:
Add the drained zucchini and sautéed vegetables to the batter and mix well. Pour the mixture into a greased baking dish lined with parchment paper. Bake at 180°C (350°F) for 35–40 minutes.
5. Prepare the Potato Layer:
Meanwhile, boil potatoes until soft, then mash or grate them. In a pan, melt butter and sauté the onion until translucent. Add garlic, carrot, and chopped tomato. Cook for 3–5 minutes. Stir in chopped parsley, salt, black pepper, and Italian herbs.
6. Mix Egg Base:
In a bowl, whisk together 2 eggs, salt, Greek yogurt or sour cream, and add to the potato mixture. Stir in half of the Parmesan cheese.
7. Assemble Final Bake:
Once the vegetable bake is cooked, layer the creamy potato mixture on top. Sprinkle the remaining Parmesan cheese. Return to the oven and bake for another 20 minutes at 180°C (350°F), or until golden brown on top.
