Ingredients

1/2 ounce dried shiitake or porcini mushrooms, finely chopped
2 cups boiling water
1/3 cup olive oil, divided
4 yellow onions (about 2 pounds)
4 cloves garlic, finely minced
1/2 pound cremini mushrooms, cleaned and sliced
1 large sprig fresh rosemary
1 cup Arborio or short-grain white rice
1/2 cup dry white wine, such as Sauvignon Blanc
2 tablespoons balsamic vinegar
2 cups vegetable broth
1 teaspoon salt
1/2 teaspoon freshly ground black pepper, plus more to garnish

Steps:

Heat the oven to 300°F. Rehydrate dried mushrooms. Set them aside to steep while you cook the onions. Chop one of the onions into a fine dice. Heat 2 tablespoons of the olive oil in a 3-quart (or larger) ovenproof pot or Dutch oven over medium heat. Add the onion and garlic and cook, stirring occasionally, for about 8 minutes, or until soft and golden. Push the onions to the side of the pot, and turn the heat up to medium-high. Add all the sliced cremini mushrooms and let them cook for 5 minutes without stirring. Flip the mushrooms and cook for another five minutes, or until they are quite brown and a crust is developing on the bottom of the pan. Drain the dried mushrooms, reserving the liquid. Add the mushrooms and rosemary sprig to the pan and sauté briefly, mixing with the onion and the rest of the mushrooms. Add the rice and cook, stirring once or twice, for about 4 minutes, or until the rice begins to turn transparent. Turn the heat to high and add the white wine, vinegar, broth, and reserved mushroom steeping liquid. Stir and scrape the bottom of the pan as you add the liquid to deglaze any yummy mushroomy bits sticking to the pan. Stir in the salt and pepper. Bring to a boil. Cover the pan with a tight-fitting lid and put it in the oven to bake for 35 minutes. While the rice is baking, make the caramelized onions. Heat the remaining olive oil in a cast iron skillet. Cut the remaining three onions in half, and then slice them into thin half moons. Add them to the oil and sprinkle liberally with salt. Cook on low heat, stirring occasionally, until the onions turn a dark mahogany brown. Let them go as long as you can; I usually cook mine for at least 30 minutes. When the risotto has finished baking, let it stand uncovered for 5 minutes before serving. Dish it up and top each bowl with a spoonful of caramelized onions, a little extra pepper, and, if desired, a scoop of whipped mascarpone.
