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 olive oil to the hot Instant Pot. Then stir in the onion and minced garlic. Stirring, sauté it for 30 seconds to one minute or until it becomes fragrant.
1/2 small onion, 3 cloves garlic
Add the Arborio rice, stirring it, until it becomes toasted, about two to three 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 ten 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 ten 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 and butter. 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
