Preheat oven to 200C.
Cut the small potatoes in half and then score a shallow crosshatch pattern into the cut side of each half. Cut thick rounds from the zucchini and cut the crosshatch pattern into each piece, making sure to not cut all the way through. Cut the halloumi into cubes and score the same crosshatch pattern into each cube.
6 small potatoes*, 1 large zucchini, 180 g halloumi
Working with half of the tray only, mix half the melted butter, half the za’atar, half the aleppo pepper and half the parmesan together until you have a paste. Gently spread the paste out to cover half the tray – it’s okay to have a few small gaps in the paste, the parmesan will melt and spread a little. Add the potatoes, scored side down, and nestle them gently into the paste.
50 g butter, 2 heaped tablespoons za’ater, 2 heaped teaspoons aleppo pepper, 30 g parmesan
Roast just the potatoes for 15 minutes – yes, half the baking tray will be empty!
Remove the tray from the oven (leave the potatoes where they are – do not lift them yet!). In the empty side of the tray, combine the remaining melted butter, za’atar, aleppo pepper and parmesan. Mix to make another paste and spread it out to cover the rest of the tray. Add the zucchini and halloumi pieces, scored side down, and push them gently into the parmesan paste.
Pop the whole tray back into the over and roast for another 15-20 minutes or until everything is cooked through, golden brown and has beautiful parmesan crust on the bottom.
Serve as a traybake side or as a snack eaten right out of the baking tray!
