Keep the stock hot in a separate pan. Soften onion in 2 tablespoons oil over medium-low heat. Add courgettes and cook for 5 minutes.
Add rice and stir for 1–2 minutes. Add a ladle of hot stock and stir as it cooks.
Continue adding stock gradually until the rice is cooked but retains a little bite. Follow the rice pack as a timing guide.
Remove from the heat. Stir in the remaining oil, lemon zest and juice. Rest for 2 minutes and adjust seasoning and consistency.
