Set your Instant Pot to sauté and wait for it to get hot while prepping the other ingredients. (Get everything measured out and ready to go.) Add the diced onion and minced garlic to the hot Instant Pot. Stirring, sauté it for 30 seconds to 1 minute or until it becomes fragrant.
1/2 small onion, 3 cloves garlic
Add the Arborio rice, stirring it, until it becomes toasted, about 2 to 3 minutes.
1 1/2 cups Arborio rice
Stir in the white wine, and deglaze the bottom of the Instant Pot, scraping up all the browned bits. Stir in the chicken broth, salt, and pepper, until well combined, scraping the bottom of the Instant Pot to make sure no rice is stuck there.
1/2 cup white wine, 1/2 teaspoon kosher salt, dash black pepper, 3 1/2 cups chicken broth
Close the Instant Pot and cook at high pressure for 10 minutes. When the ten minutes is up, quick release the pressure by turning the steam release from "sealing" to "venting". From the time you close the Instant Pot to the time you open it will be about 23 minutes, this includes the time it takes to come to pressure, the 10 minutes of cook time, and the time it takes for the pressure to release.
Once the float valve has dropped remove the cover and stir in the Parmesan. Taste and adjust seasonings if needed, adding more salt and pepper. Enjoy immediately with some freshly grated Parmesan and minced parsley.
1/2 cup Parmesan cheese, 2 tablespoons unsalted butter
