Instant Pot Rigatoni with Mushroom Ragu

Ingredients

1½ pounds cremini mushrooms, trimmed and quartered1 carrot, peeled and chopped1 small onion, chopped3 tablespoons extra-virgin olive oil ½ ounce dried porcini mushrooms, rinsed and minced3 garlic cloves, minced2 tablespoons tomato paste ¾ cup dry red wine 1 (28-ounce) can diced tomatoes 1 pound 100 percent whole-wheat rigatoni 2 cups vegetable or chicken broth 1½ cups water 1 tablespoon soy sauce Grated Parmesan cheese

Before You Begin

If using traditional pasta, decrease the water to ¾ cup. Do not substitute other pasta shapes in this recipe.

Instructions

  1.  Working in batches, pulse cremini mushrooms in food processor until pieces are no larger than ½ inch, 5 to 7 pulses; transfer to large bowl. Pulse carrot and onion in now-empty processor until finely chopped, 5 to 7 pulses; transfer to bowl with mushrooms.
  2.  Using highest sauté function, heat oil in Instant Pot until shimmering. Add processed vegetables and porcini mushrooms, partially cover pot, and cook, stirring occasionally, until vegetables release their liquid, about 5 minutes. Uncover and continue to cook until liquid has evaporated and vegetables begin to brown, 8 to 10 minutes.
  3.  Add garlic and tomato paste and cook, stirring frequently, until fragrant, about 30 seconds. Stir in wine, scraping up any browned bits, and cook until mostly evaporated, about 1 minute. Stir in tomatoes and their juice, rigatoni, broth, water, and soy sauce.
  4.  Lock lid into place and close pressure-release valve. Select high pressure-cook function and cook for 5 minutes. Turn off Instant Pot and quick-release pressure. Carefully remove lid, allowing steam to escape away from you.
  5.  Stir rigatoni and sauce to combine. Partially cover pot and let sit until rigatoni is tender and sauce is thickened, 5 to 8 minutes. Season with salt and pepper to taste. Serve, passing Parmesan separately.

Why This Recipe Works

For complexity, we turned to two types of mushrooms: Dried porcini delivered depth of flavor, while a whopping 1½ pounds of fresh cremini gave the sauce substantial feel. To round out the sauce's umami qualities, we added a splash of soy sauce and some tomato paste, while a bit of red wine and diced tomatoes added the right amount of fruity acidity and body. To make prep easy, we used the food processor to chop the cremini, onion, and carrot. The key to success was pairing this rich sauce with the right pasta: Rigatoni proved to be a great match, with its sturdy body (to stand up to the heavy sauce) and its delicate ridges (to which the sauce could adhere). After cooking everything under pressure, we let the pasta and sauce rest until the sauce was perfectly thickened. A sprinkle of grated Parmesan cheese was a simple, classic finish.
