In a large mixing bowl, combine the sliced potatoes and zucchini. Season with salt, black pepper, dried oregano, and rosemary. Add the chopped parsley, minced garlic, and a generous drizzle of extra virgin olive oil. Toss thoroughly to coat all vegetables evenly.

Spread half of the canned diced tomatoes with their juice evenly over the bottom of a large, oven-safe round pan or skillet.
04 -
Arrange the seasoned potatoes, zucchini, and sliced onions in rows, alternating, to fill the pan. If using a rectangular or deep dish, simply evenly distribute the vegetables.
05 -
Pour any excess olive oil and garlic mixture from the mixing bowl over the arranged vegetables, then top with the remaining canned diced tomatoes and juices.
06 -
Cover the pan loosely with aluminium foil, ensuring it does not touch the vegetables. Bake at 200°C for 45 minutes.

Remove the pan from the oven, carefully take off the foil, and return to the oven. Roast uncovered for an additional 30–40 minutes, until the vegetables are tender, edges are charred, and most liquid has evaporated.

Remove from the oven. Serve warm or at room temperature with an extra drizzle of extra virgin olive oil as desired.
