In a 2-quart pot, heat the chicken broth so that it is warm for the risotto making.
Meanwhile, in a 4-quart pot, heat the olive oil over medium heat. When the oil is hot, add in the onion.
Cook until the onion is translucent, about 2 minutes. Add in the rice.
Stir to coat the rice completely in the oil and allow to cook, stirring frequently, until the rice turns fragrant and begins to turn translucent on the edges. It will also begin to make a popping sound. Add in the wine.
Cook until the wine is almost completely absorbed by the rice, but some moisture remains.
Ladle in 1 cup of the warm broth and cook until the broth is almost completely absorbed (about 5 minutes). Be sure to stir frequently to prevent sticking to the pan.
Ladle in 1 more cup of warm broth and repeat.
Ladle in the last cup of broth and repeat.
Taste test- the risotto should be creamy but still have a bite to it (al dente). If it is not quite al dente yet, add 1/2 cup more of broth and repeat step 6.
Remove from heat and add in the butter and Parmesan. Stir until the butter and cheese has melted and the risotto is creamy.
Spread into a pan and allow to cool for 10 minutes before covering and cooling completely in the refrigerator for at least 1 hour and up to overnight.
