Add 1-2 tablespoons of olive oil to a large pan on a medium heat. Add the finely chopped onion and saute until soft but not browned (about 5-10 minutes).
Next, add the risotto rice and stir for 1 minute to coat in the oils. Next add 1-2 ladlefuls of stock to the rice and stir it until it’s mostly absorbed. Add a good pinch of salt at this point if you are using low-sodium stock.
Continue the process, adding 1-2 ladlefuls of stock at a time and letting it absorb before adding more. By the end of the process, the rice should be cooked through (about 20 minutes).
When you’ve used up all the stock and the risotto is ready, turn off the heat and add the butter, stir in until melted.
Next, stir in the zest of 1 lemon and the juice of half the lemon. Finally, stir in 1-2 tablespoons of Parmigiano Reggiano or to taste.
Check for seasoning and add more salt as needed.
Tip: Depending on the size and tartness of the lemon you’re using you can add more to taste.
Serve in bowl and garnish with either more lemon zest or Parmigiano.
