Ingredients

  • 8 ounces pappardelle pasta
  • 1/4 cup extra virgin olive oil
  • 3 medium onions, thinly sliced
  • 12 ounces shiitake mushrooms, stemmed and sliced
  • 8 ounces sliced white mushrooms
  • 4 garlic cloves, thinly sliced
  • 1 tablespoon chopped fresh oregano
  • 1/4 teaspoon +1/8 teaspoon salt, divided
  • 6 cups coarsely chopped mustard greens
  • 2 tablespoons unsalted butter
  • 1 cup shredded Asiago cheese
  • 1/4 teaspoon ground black pepper

Directions

  1. Bring a large pot of salted water to a boil. Add the pasta and cook according to package directions; drain (reserving 1/2 cup cooking liquid), rinse under cold water and drain again.
  2. Heat 2 tablespoons of the oil in a large nonstick skillet over medium. Add the onions and cook until golden brown, about 15-16 minutes. Transfer to a bowl and reserve. Add the remaining oil to the skillet and stir in the shiitake mushrooms, white mushrooms, garlic, oregano and salt; cook until the mushrooms are browned and tender, about 16-18 minutes. Add the mustard greens and cook, stirring often, until the greens are wilted, 3-4 minutes. Stir in the onions, pasta and reserved cooking liquid and cook, tossing, until hot, about 2 minutes. Stir in the butter until melted. Remove from the heat and stir in 3/4 cup of the cheese, remaining 1/8 teaspoon salt and pepper. Divide among 4 bowls and sprinkle each with the remaining cheese.
