Instructions
Begin by soaking the butter beans overnight in plenty of cold water; this step softens the beans and reduces cooking time, so be patient for the best texture. Once soaked, drain and rinse the beans well to remove any residue. Transfer the beans to a large pan and cover them with fresh water. Bring to a gentle boil over medium-high heat, then lower the heat to a simmer and cook uncovered for approximately 50 minutes. The goal is to have the beans tender but still holding their shape, not mushy. Drain the beans carefully and set them aside. Preheat your oven to 180°C (160°C for fan ovens) or gas mark 4. Meanwhile, heat the olive oil in a spacious frying pan over medium heat. Add the chopped onion and garlic, cooking slowly for about 10 minutes until they become soft and fragrant but avoid browning, which can turn the flavor bitter. Stir in the tomato purée and cook for an additional minute to deepen the flavor. Next, add the peeled chopped tomatoes, sugar, dried oregano, and a pinch of cinnamon—the cinnamon gently warms the dish without overpowering it. Allow this sauce to simmer for 2 to 3 minutes, stirring occasionally, to meld the flavors. Season generously with salt and freshly ground black pepper to taste, then fold in the drained butter beans, ensuring each bean is well coated with the luscious sauce. Pour the mixture into a large ovenproof dish, spreading it out evenly. Place it in the preheated oven and bake uncovered for about 1 hour. Do not stir during baking; this helps the beans to absorb all the wonderful flavors and lets the sauce thicken into a rich coating. Once baked to tender perfection and bubbling with flavor, remove the dish from the oven and allow it to cool slightly. Just before serving, sprinkle the chopped parsley over the top and drizzle with a little extra virgin olive oil to add brightness and richness. Tip: For an even more intense flavor, consider preparing the sauce a day ahead and refrigerating it overnight before assembling the dish. This resting time allows the herbs and spices to blend deeply with the tomatoes and beans.
