In a sauté pan, heat the oil over medium heat and then gently fry the onion, carrot, celery and garlic for 2-3 minutes until soft.
Add the parsley, oregano, cinnamon (if using), salt and pepper. Stir well to combine.
Add the tomato paste, passata and vegetable stock and the drained beans and bring to a simmer. Remove from the heat.
Transfer the bean mixture to a shallow ovenproof dish and spread out evenly. Cover with foil and bake in the oven for 25 minutes.
Remove the foil and continue to cook for another 10 minutes, until the sauce has thickened a little. Remove from the oven, cover lightly and leave to cool completely.
Serve at room temperature.
Notes
Serving
Gigantes Plaki is traditionally served at room temperature, but it’s also excellent warm from the oven.Serving Ideas Enjoy with crusty bread and a simple salad, or serve as a mezze-style side with grilled lamb chops, chicken skewers or roasted fish.Beans Authentically this dish uses Greek gigantes beans, but butter beans (lima beans) are the closest substitute and work perfectly.Storage Store in an airtight container in the fridge for up to 4 days. The flavour improves as the beans soak up the sauce.Freezing Freeze for up to 3 months. Defrost overnight in the fridge and bring to room temperature or warm gently before serving.
