Step 2

Heat the oven to 180C/160C fan/gas 4. Heat the olive oil in a large frying pan, add the onion and garlic, and cook over medium heat for 10 minutes until softened but not browned.

Step 3

Add the tomato purée and cook for 1 minute. Add the tinned tomatoes, sugar, oregano, and cinnamon, simmer for 2–3 minutes, and season generously. Stir in the par-cooked beans.

Step 4

Tip the mixture into a large ovenproof dish. Bake uncovered, without stirring, for approximately 1 hour until the beans are completely tender and the sauce has thickened.

Step 5

Allow to cool slightly, then scatter with parsley and drizzle with a little more olive oil before serving.
