Ingredients

  • 1 tablespoon olive oil or butter
  • 1/2 cup finely chopped onions
  • 1 1/2 cups arborio rice
  • 1/2 cup dry white wine or dry vermouth
  • 3 to 3 1/2 cups chicken or vegetable broth
  • 1 ounce dried porcini, broken into bits
  • 1 cup frozen peas
  • 1/2 cup grated Parmesan, plus more to pass at the table
  • Salt and freshly ground pepper to taste
  • 2 tablespoons chopped parsley, for garnish

Method

  • Heat the oil in a 2 1/2-quart or larger pressure cooker.
  • Add the onions, and cook over high heat for 1 minute, stirring frequently.
  • Stir in the rice, taking care to coat it with the oil.
  • Cook for 30 seconds, stirring constantly.
  • Stir in the wine.
  • Cook over high heat until the rice has absorbed the wine, about 30 seconds.
  • Stir in 3 cups of the broth and the porcini, taking care to scrape up any rice that might be sticking to the bottom of the cooker.
  • Lock the lid in place.
  • Over high heat, bring to high pressure.
  • Reduce the heat just enough to maintain high pressure, and cook for 4 minutes.
  • Turn off the heat.
  • Quick-release the pressure by setting the cooker under cold running water.
  • Remove the lid, tilting it away from you to allow the steam to escape.
  • Set the cooker over medium-high heat, and stir vigorously.
  • The risotto will look fairly soupy at this point.
  • Boil while stirring every minute or so, until the mixture thickens and the rice is tender but still chewy, 1 to 4 minutes.
  • Stir in the peas when the rice is almost done.
  • (If the mixture becomes dry before the rice is done, stir in the extra 1/2 cup of broth.
  • The finished risotto should be slightly runny; it will continue to thicken as it sits on the plate.)
  • Turn off the heat.
  • Stir in the Parmesan, and salt and pepper to taste.
  • Serve immediately, garnished with a little parsley.
  • Pass extra Parmesan at the table.
