In a small saucepan over low heat, warm 4 cups low sodium chicken broth. Allow to simmer on low while cooking the arborio.
In a Dutch oven or large pot over medium-high heat, add 2 tablespoons olive oil and 1 cup finely chopped onion and sauté until the onions are soft (about 3-4 minutes).
Add 1¼ cups arborio rice and 2 tablespoons minced garlic and stir until the rice begins to brown (about 5 minutes). Stir continuously so as not to allow the rice to burn while browning. Add ½ cup white cooking wine and continue to cook and stir until the wine has dissipated.
Next, add ½ cup of the chicken broth, stirring and cooking until the liquid is gone from the pot. Add broth in ½ cup increments, allowing each portion of broth to absorb into the rice before adding the next portion. Continue to add in ½ cup increments until all broth has been added. Stir continuously. This will take about 15 - 20 minutes.
Once all of the broth is absorbed, remove from heat and stir in ¾ cup grated Parmesan, 2 tablespoons unsalted butter, ½ teaspoon kosher salt, ½ teaspoon ground black pepper, and 2 tablespoons chopped parsley.
Garnish with shredded Parmesan and 1 tablespoons chopped flat-leaf parsley.
Serve and enjoy!
