Using the sauté setting, heat the olive oil over "normal" heat for a minute.
1 Tablespoon extra virgin olive oil
Add the onion, and sauté for 2-3 minutes until it becomes translucent.
1 medium yellow onion
Add the garlic, thyme, and a good pinch of salt, and sauté for 3-5 minutes, stirring often, until the onions are golden brown.
2 cloves garlic, ½ teaspoon dried thyme
Add the rice, and stir to combine with the onions, toasting the rice for about one minute.
1 ½ cups short-grain brown rice
Add the wine, and stir constantly until it is mostly evaporated.
½ cup dry white wine
Hit cancel on your Instant Pot to end the sauté setting. Add the vegetable broth, and stir well, scraping the bottom of the pot to ensure there aren't any bits stuck to the bottom.
3 cups vegetable broth
Put the lid on the pot and ensure the vent is set to "sealing". Set to manual / high pressure for 24 minutes.
When the cooking cycle is complete, allow the pressure to release naturally for 15 minutes, and then quick-release the remaining pressure.
Remove the lid, and add the butter and the Parmesan cheese. Stir for 1-2 minutes to create a creamy texture.
2 Tablespoons butter, ½ cup freshly grated Parmesan cheese
Stir in the frozen peas if you like.
½ cup frozen peas
Serve topped with more Parm.
