Switch the oven on to 200°C and move one rack to the middle.
02 -
Drop potatoes and zucchini into a big bowl, toss in some salt and pepper, then sprinkle rosemary and oregano. Toss in parsley and minced garlic, give them a good splash of olive oil, and mix around so every piece gets coated.
03 -
Pour about half the diced tomatoes (with all their juice) right onto the bottom of a big round skillet or oven-proof pan.
04 -
Start lining up the onions, zucchini, and potatoes, switching back and forth, to cover the whole pan. If you’re using a deep or rectangle pan, just make sure to spread everything out evenly.
05 -
Whatever’s left of the oily garlic mix from the bowl, drizzle it all over the veggies. Pile on the rest of the diced tomatoes and their juices.
06 -
Loosely lay foil on top but don’t let it touch the food. Let it bake in the oven for 45 minutes at 200°C.
07 -
Take the hot pan out, remove the foil, then pop it back in. Bake, uncovered this time, for another 30 to 40 minutes. You want the edges to get a little crispy and most of the liquid to go away.
08 -
Set it out of the oven. Give it a final pour of olive oil if you like. Tastes awesome warm or once it’s cooled a bit.
