Place the potatoes, onion and garlic in a large roasting tray.
Add the olive oil, passata, sundried tomato paste, water, allspice, smoked paprika, sugar, salt and black pepper.
3 Tbsp extra virgin olive oil, 250 ml passata, 2 Tbsp sundried tomato paste, 125 ml water, ¼ tsp allspice, ½ tsp hot smoked paprika, ¼ tsp sugar, 1 tsp fine sea salt, freshly ground black pepper
Toss everything well so the potatoes are coated in the sauce. Spread into an even layer.
Cover the tray tightly with foil and bake for 40 minutes.
Halfway through
Remove the tray from the oven and carefully lift off the foil. Stir everything gently and check that the potatoes are almost tender. If the tray looks dry and the potatoes still need time, add a splash more hot water.
Add the drained butter beans and cherry tomatoes. Stir gently so the beans are coated without being crushed.
Return the tray to the oven, uncovered, and bake for another 20 - 30 minutes, or until the potatoes are fully tender and the sauce has thickened and is bubbling around the edges.
Finish and Serve
Remove from the oven. Finish with extra olive oil, lemon juice, parsley, Aleppo pepper and more black pepper.Serve as suggesyed in the article above: with bread, couscous, rice, or as part of a mezze spread.
